Pale are: palpi, tegula, legs (except for arioli and extreme inner tip of metatibia); in fore wing base and apex of costa, apex of subcostal, base of stigma (Fig. 23A), R1, 1A, 2A+3A [color differences between veins of hind wing not clearly definable]; margins of median excision of abdominal tergum 1, medio-distal part of terga 2-4 (-6) [pale area on tergum 3 is the largest of these], all sterna, more or less the downturned parts of terga 2-8, more or less hypopygium and ovipositor valvifer 2. Wing membranes hyaline. Head. Pedicel about as long as scape. Head in lateral view with widest point on temple about equal to length of pedicel (Fig. 23E). Malar space slightly shorter than diameter of anterior ocellus. Lowest part of gena densely sculptured, without shining interspaces between the ill-defined pits (Fig. 23E). Clypeus densely pitted, weakly shiny; anterior margin widely emarginate, to about 0.4 of its length (Fig. 23D). Setae on upper head as long, or longer than, diameter of anterior ocellus (Fig. 23E). Thorax. Whole pronotum except for small antero-ventral area dull, with sculpture (Fig. 23H). Pits on upper mesepisternum large and well-defined (Fig. 23H). Mesoscutellum with large, scattered pits anteriorly and laterally, interspaces shiny; medially and posteriorly nearly without pits and entirely unsculptured (Fig. 23F). Anterior of mesoscutellar appendage densely pitted, with numerous setae, only small posterior area unpitted (Fig. 23F). Abdomen. Anterior of tergum 1 densely setose. Terga 2 and 3 glabrous. Terga increasingly setose from tergum 4 to apex of abdomen. Weak surface sculpture on tergum 2 becoming stronger on more distal terga. Sawsheath in dorsal view broad, with blunt tip (Fig. 24C). In lateral view exposed length of cercus about 0.5 × as long as exposed upper length of valvula 3 (Fig. 23G). Lancet (Fig. 24B, C): 13-14 serrulae; apical serrulae short and high.

Finland: Nylandia, Vantaa, YKJ grid coordinates: 669:37, 17.06.2021, 1♀, leg. Miikka Friman. Etymology. Named after Matti Viitasaari, who first recognised a very large female of this species as probably not belonging to Heptamelus ochroleucus or H. dahlbomi. Habitat. Damp, shady places in woodland. Biology. Many female specimens have been reared from larvae in Athyrium filix-femina (L.) Roth. (Fig. 25). Larvae found abundantly in 2021 in Matteucia struthiopteris (L.) Tod. in Kitee, Finland, were provisionally identified as H. viitasaarii by genetic comparison (identical to adults), as later confirmed when females started to emerge in 2022. The larvae feed inside the rachis, eating alternate portions nearly completely, or only partly (Fig. 25B, C). This results internally in a “ladder-like” appearance, which is externally clearly visible, especially against the light (Fig. 25A). This feeding habit is, however, possibly widespread in Heptamelus: at least H. dahlbomi larvae feed in the same way. Larvae of H. viitasaarii in M. struthiopteris regularly overwinter in a chamber made within the fertile fronds at the base of the stem. Strangely, no males have so far been reared, and the few males so far netted are all from a single locality (within an area of less than 1km2). It was observed that adults reared from plants of different size varied very much in body size, and that the smallest individuals had been feeding on the smallest plant, with correspondingly thin stalks. Distribution. Finland (North and South Karelia, Tavastia, and Helsinki area), Russia (Moscow). The record from Moscow was published by Vikberg (2017) as Heptamelus ochroleucus. Differential diagnosis. The characters which are most useful for the identification of European Heptamelus species are presented below in a key. The extensively pitted and setose mesoscutellar appendage distinguishes H. viitasaarii from the two other European species, as well as H. magnocularis Malaise, 1931 (Malaise 1931b) from the Russian Far East (see Liston et al. 2018). Note that all body parts of H. viitasaarii are conspicuously more densely setose, and pitted, than most other Heptamelus species which we have so far examined. From the females of Heptamelus dahlbomi, H. ochroleucus, H. magnocularis, H. montanus Togashi, 1961, and H. takeuchii Togashi, 1961 (the latter two from Japan), H. viitasaarii differs in its much shorter and higher apical serrulae of the lancet (Fig. 24A, B). Heptamelus viitasaarii has a wider sawsheath in dorsal view than either H. dahlbomi or H. ochroleucus. Heptamelus japonicus Togashi, 1961, only known in the male sex, differs from H. viitasaarii in its entirely pale thorax, abdomen and fore wing pterostigma. The male of H. takeuchii differs from H. viitasaarii in its more shallowly emarginate and smoother clypeus, and the pale abdominal sternum 9. The male of H. montanus resembles that of H. viitasaarii in coloration, but as in females of these species, the clypeus of H. montanus is much less deeply emarginate (approx. to about 0.2 of its length) and the setae on the upper head shorter (mostly shorter than the diameter of the anterior ocellus)., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Vikberg, V, 2017.

Phymatoceropsis sibiricola (Zhelochovtsev, 1939) comb. nov. Figs 28, 29 Notes. Rhadinoceraea sibiricola Zhelochovtsev, 1939: 159-160. ♀. Holotype. Type locality: Russia, Krasnoyarsk Krai, Vostotschnoe (35 km SE of Minussinsk). In the original description, Zhelochovtsev (1939) compared R. sibiricola with " Rh. japonica Malaise" [Phymatoceropsis japonica (Malaise, 1931) (Malaise 1931a)], and stated that they are "closely allied". Comparison of female P. sibiricola specimens from Finland (Fig. 28) with a Japanese female of P. japonica in the SDEI collection confirmed their similarity. As mentioned by Zhelochovtsev, P. japonica has much longer antennae, but the differences described in the structure of the frontal area and mesopleura seemed less clear. The host plant of P. sibiricola, as discovered by Vikberg in Finland (see below), is Sambucus racemosa (Adoxaceae), since verified several times by Mutanen. The host plant of P. japonica is Sambucus sieboldiana Blume (Okutani 1956), which is sometimes treated as a synonym or subspecies of S. racemosa L.

Oviposition trial by Vikberg (3/2011 VV): three females captured in Hangastenmäki in 2011 were used in this experiment. Adoxa, Sambucus racemosa, Lonicera xylosteum and Galium sp. were offered to them. They laid eggs only on Sambucus racemosa leaves. The egg is laid through the upperside of the leaf into the tissue of the underside, usually one to two eggs per leaflet, but in one small leaflet eight eggs were counted. Oviposition occurred on 21.05.-24.05. The first larvae were observed on the morning of 28.05. Later, 28 larvae were counted. Five feeding instars were observed and after finishing feeding there was an "extra moult". Prepupae were seen on 07.06-08.06. 1st and 2nd instar larvae are gray, with a brown head. 5th instar larvae are 13-14 mm long; head width ca. 1.6 mm (Fig. 29). Head brownish, behind the eye a black fleck which is curved backwards and upwards. Body dorsally dark gray with greenish hue; ventrally whitish gray. Black suprastigmal flecks on thoracic segment 3 and abdominal segments 1-9.

Calameuta haemorrhoidalis: Gussakovskij (1935), Benson (1946), and most subsequent authors. Type material examined and taxonomic notes. Lectotype of Cephus variabilis Mocsáry, 1886, hereby designated: ♀, id nr.017651 HNHM Hym.coll. (Fig. 5A); labels (Fig. 5A). Type locality: Romania, Herkulesfürdõ (HNHM). Paralectotypes (all HNHM): 5♂ and 2♀ also belong to the type series and have been labelled as paralectotypes: details of their sexes and localities were given by Zombori (1978). Note that the type series is heterogeneous, and contains specimens of Calameuta punctata as well as C. variabilis. Zombori noted the heterogeneity of the type series, but did not publish a lectotype designation, although the specimens were labelled by him as lectotype and paralectotypes. The types were found by Z. Vas in the HNHM, grouped as stated by Zombori. We do not follow Zombori’s intention according to his labels, but designate the female from Herculesfürdö (= Baile Herculane, Romania) (id nr. 017651 HNHM Hym. coll., labelled by Z. Vas) as lectotype (Fig. 5A). Thus, Calameuta variabilis (Mocsáry, 1886) comb. nov. can be used as a valid name for Calameuta haemorrhoidalis sensu Gussakovskij et auct. Cephus atripes Stephens, 1835 has sometimes been listed as a synonym of C. variabilis, e,g. by Taeger et al. (2010, under Calameuta haemorrhoidalis). The type specimen, or specimens, is probably lost. The description is short, and does not state the sex of the described specimens(s). de Dalla Torre (1894) treated C. atripes as a synonym of C. pygmeus (Linnaeus, 1767) and Konow (1905a) as a synonym of C. haemorrhoidalis. The color pattern described by Stephens does not fit very well with either of these, in either sex, nor with any other known north-west European cephid species. Stephens’ name is best treated as a species inquirendae. Biology and distribution. According to Macek et al. (2020, under Calameuta haemorrhoidalis) the host plants of C. variabilis are various Poaceae, including cereals such as rye (Secale cereale) and wheat (Triticum). According to our personal experiences, adults occur in dry places, mostly on or near wild grasses. The taxon to which the name C. variabilis is now applied has so far been found only in the West Palaearctic, and has an essentially Mediterranean distribution, summarized by Gussakovskij (1935) as comprising southern Europe, Crimea, Caucasus, western Turkmenia (Kopet-Dagh) and Syria. In Central Europe, it reaches at least as far north as Hungary (Zombori 1978), but specimens recorded from Austria and the Czech Republic (see Taeger et al. 2006) should be checked., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Ghigi, A, 1905.

Dolerus junci (Stephens, 1835) nom. rev. Dosytheus Junci [sic!] Stephens, 1835: 84-85. Sex not explicitly stated. Syntypes. Published type localty: "Devonshire, and near Windsor" (England). Lectotype designated below. Dolerus Busaei [sic!] Snellen van Vollenhoven, 1858: 277. Sex not given. Lectotype ♂ designated by Thomas (1987). Type locality: “Haarlem” (Netherlands). syn. nov. Dolerus cothurnatus auct. nec Serville, 1823 (e.g. Benson 1952, Zhelochovtsev 1994, Lacourt 2020). Dolerus thargitai Zombori, 1994: 185-187. ♀. Holotype. Type locality: Csíkszentkirály, Borsáros, Kérújfürdő: Tolvajos patak (Romania). syn. nov. Remarks. Similarly to the melanic color form of D. yukonensis (see below), which was described as a distinct species, D. scoticus, by Cameron (1881a), the melanic form of D. junci was also described as a distinct species, D. thargitai, by Zombori (regarded as a synonym of D. yukonensis / D. scoticus until now). The melanic color form of D. junci has also been recorded from central Europe (Germany) and southern Europe (Italy, Switzerland: see, e.g. Pesarini 2012), but is not known from Fennoscandia. The males of the melanic forms of D. junci (01.06.1984) and D. yukonensis (24.05.1984) have been collected at the same locality at nearly the same time (Germany: Federsee, Brackenhof, leg. E. Jansen, CEJ). In addition to their different penis valve structure and other characters used in the keys by Benson (1952) and Zhelochovtsev (1994), D. junci and D. yukonensis differ in the shape and sculpture of the mesoscutellar appendage: almost unsculptured and without a distinct longitudinal keel in the former, and clearly sculptured and with a distinct keel in the latter. Most likely, the melanic color form of D. junci does not occur within the geographic range of D. incisus, but they can also be distinguished by the shape and the sculpture of the mesoscutellar appendage: meshed (nearly matt) and long, with a distinct median longitudinal keel (D. incisus) versus short and almost unsculptured (more or less glossy) and without a distinct median keel (D. junci). Type material examined and taxonomic notes. Dosytheus junci Stephens, 1835. Lectotype ♀ hereby designated, labelled: "Type H.T. [holotype]" [round with wide red margin, printed; not a holotype but a syntype!], "B.M. TYPE HYM. [printed] 1.575.", "B.M. TYPE HYM.

Condition: legs partly destroyed, left midleg missing, the apical flagellomeres missing, apex of left forewing broken. BMNH. The original description of D. junci by Stephens (1835) refers to syntypes ("Devonshire and near Windsor"). Although Kirby (1882) mentioned a "Type of D. junci ", this cannot be regarded as a lectotype designation, even though he was apparently only able to locate a single specimen. Dolerus busaei Snellen van Vollenhoven, 1858. Photos of the lectotype and of the penis valve were checked. Left midleg and two segments of the right antenna missing; the genital capsule is glued on a card. RMNH. This nominal taxon was previously treated as a synonym of D. cothurnatus auct. Dolerus cothurnatus auct. nec Serville, 1823. Haris and later Lacourt (2000) studied the syntypes (3 ♂) of D. cothurnatus Serville, but not their genitalia. Based on their penis valve structure, none of the syntypes fits D. cothurnatus auct.: the two syntypes (among them the one labelled as lectotype) represent D. germanicus and the third one is a male of D. aericeps. The name D. cothurnatus by Serville is placed here as a junior synonym of D. germanicus, by designating its lectotype (see also under D. germanicus), and the name Dolerus junci (Stephens, 1835) has to be used for D. cothurnatus auct. nec Serville. Dolerus thargitai Zombori, 1994. The holotype and some paratypes (2♀, 4♂) were studied. HNHM.

Lectotype designated by Malaise and Benson (1934). LSUK. Images of the lectotype (LINN 2402) in dorsal and lateral view are available (The Linnean Society of London 2022). Tenthredo sericea Linnaeus, 1767: 921. Sex not stated [but probably female, because dark dorsal patches on abdomen are not mentioned]. Syntypes (assumed). Type locality: Leipzig. syn. nov. Abia sericea: de Dalla Torre (1894), Konow (1905b), Enslin (1917), Liston and Späth (2006), Taeger et al. (2010). Abia dorsalis Costa, 1859: 5-6. ♀. Holotype [not examined]. Type locality: Italy, Cape Miseno near Naples. syn. nov. Notes. Abia nitens was successively mentioned as occurring in Sweden by Fallén (1807), Dahlbom (1836), and Thomson (1871), who all placed Tenthredo sericea as its synonym. Thomson’s description of leg color indicates that he had before him specimens of the species called by Taeger (1998) A. sericea, or perhaps A. candens [not distinguished from the former in Thomson’s time]. Influenced by the continued, widespread use of the name Abia nitens in Scandinavian literature, Taeger et al. (2006) and ArtDatabanken (2015) included Sweden within the range of A. brevicornis [as A. nitens auct.]. In fact, no Swedish specimens of A. brevicornis have been located in the MZLU or NHRS collections, and there are no published records from other Fennoscandian countries. Abia brevicornis is restricted to extremely dry, summer-warm sites, where its larval hosts occur (Scabiosa spp.) (Liston and Späth 2006). Probably it has a strongly continental distribution: its most north-westerly known localities in Europe are in Central Germany, whereas it is not definitely known in France (Noblecourt 2020), and a single old record from Spain needs confirmation. Although a presence of A. brevicornis in southern Sweden cannot be ruled out, we consider it likely that all references to A. nitens auct. in Sweden relate to either A. nitens [= Abia sericea] or A. candens., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Malaise, R, Benson, RB, 1934.

Pristiphora coactula (Ruthe, 1859) Nematus coactulus Ruthe, 1859: 307-308. ♀. Holotype. Type locality: Iceland. Lygaeonematus (Lygaeotus) trochantericus Lindqvist, 1952: 101-102. ♀. Holotype (http://id.luomus.fi/GL.7708) and paratypes (♀, ♂). Type locality: Finland, Utsjoki, Outakoski. syn. nov. Notes. The nuclear sequence data obtained for this study revealed three main clusters within the Pristiphora carinata group: P. carinata, P. coactula, and P. borea + P. groenblomi + P. albilabris (Fig. 30). No nuclear sequence data are yet available for P. breadalbanensis (Cameron, 1882b) and P. lativentris (Thomson, 1871). A nearly perfect match morphologically to the L. trochantericus holotype is ZMUO.035514, which falls within the P. coactula cluster based on nuclear DNA (Fig. 30). There are two main clusters based on COI sequences, one of which contains only P. borea (Konow, 1904) and P. groenblomi (Lindqvist, 1952) and the other one all species (Fig. 31). Within the COI cluster containing all species (Fig. 31), P. borea, P. groenblomi, and P. albilabris (Boheman, 1852) (Betula feeders) tend to separate from P. coactula (Salix) and P. carinata (Hartig, 1837) (Vaccinium). Based on the specimens having nuclear data, the species (mainly females) of the Pristiphora carinata group may be separated by the following key, although it might not always work for all specimens, particularly P. coactula and P. borea. Excluded from the key are the (sub)arctic species P. breadalbanensis and P. lativentris. Pristiphora Pristiphora lativentris may have somewhat different serrulae from the other species (almost papilliform, see fig. 215 in Prous et al. 2017). The identity of Pristiphora breadalbanensis (most similar to P. borea and P. coactula) needs further research to confirm if characters (e.g. structure of median mesoscutal lobes) mentioned by Benson (1958) to separate this species are reliable. [table omitted] Examples of lancets of P. borea, P. carinata, and P. coactula are shown in Fig. 32A-C, but more specimens need to be examined to check if there are any consistent differences between the species. Morphological differences between the males of P. borea, P. carinata, and P. coactula are not clear. Externally, it seems that P. coactula tends to be paler (clypeus, pronotal angles, tegula, metafemur, and sternum 9 completely or mostly pale) than P. borea and P. carinata. The dorso-apical margin of the paravalva of P. borea (Fig. 34B) may be more strongly inclined basally compared to P. carinata and P. coactula, but differences between the penis valves of the latter two species are not clear (Fig. 34A, D, E). The most distinctive penis valve in the P. carinata group seems to belong to P. albilabris (Fig. 34F), which has the most distinctly inclined dorso-apical margin of paravalva. Overall shape of penis valve of P. groenblomi (Fig. 34C) is most similar to P. borea, but it may be larger., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Prous, M, Kramp, K, Vikberg, V, Liston, A, 2017.

Cephalcia intermedia: Vikberg (1982); raised to species rank. Van Achterberg and van Aartsen (1986); synonymy with C. lariciphila (Wachtl, 1898). syn. nov. Notes. Cephalcia intermedia has in recent years mostly been understood as a distinct species close to C. arvensis (e.g. Viitasaari 2002b, Taeger et al. 2006), but with more extensively dark-patterned adults, occurring in northern Europe and the central European mountains. Because of its dark coloration, specimens of C. intermedia can also be mixed up with C. lariciphila (Wachtl, 1898), but the host plant of C. intermedia is Picea, as in C. arvensis, not Larix as in C. lariciphila. The status of C. intermedia and the supposed differences to C. arvensis were discussed by Vikberg (1982), Shinohara (1985), Midtgaard (1987) and Viitasaari (2002b). The only differences between C. arvensis and C. intermedia are in coloration: mainly of the abdomen, and less so of the antennae and legs. Shinohara (1985) pointed out that an unbroken range of color variability occurs between pale C. arvensis and the dark specimens identified as C. intermedia. This is in accordance with our observations, as the amount of dark color on the male abdomen varies considerably even in a single locality (Fig. 6). Small differences in colouration of larvae are possibly not constant, as the larvae of C. intermedia used for comparison were offspring of a single female. At present, there seems to be no convincing evidence for treating C. intermedia as a species distinct from C. arvensis, and we therefore synonymize them., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Blank, SM, Taeger, A, Liston, AD, Smith, DR, Rasnitsyn, AP, Shinohara, A, Heidemaa, M, Viitasaari, M, 2009.

Among 2♀ and 1♂ specimens preserved in the ZMUC collection under the name T. eglanteriae, only the above female can be regarded as a syntype. The scutellum of the other female is red, and the tip of the abdomen of the male black. Both characters conflict with Fabricius’ original description. Compared with the other two specimens, the pale parts of the legs of the lectotype are darkened. The lectotype agrees with the species which has for a long time been known as Dolerus aericeps Thomson, 1871 (Zhelochovtsev 1994), characterized for example by the laterally directed and distally curved setae of the ovipositor sheath. Lacourt (2000) used the name D. bajulus Serville, 1823 for this species, but Blank et al. (2009) presented arguments for the use of the name D. aericeps (nomen protectum) versus D. bajulus (nomen oblitum). Tenthredo eglanteriae was synonymized with T. germanica by Klug (1819) and with Athalia glabricollis Thomson, 1870 by Konow (1897a). Since Brullé (1846), T. eglanteriae (nomen oblitum) has never again been used as valid, while between 1971-2021 the name Dolerus aericeps (nomen protectum) was used as valid by more than 120 authors in over 150 publications (Article 23.9.1, ICZN 1999).

They comprise a distinct cluster BIN BOLD:ABV8002, with 0.3% intraspecific variability. Based on sequences longer than 600 bp, the minimum distance to the closest relative D. aericeps (n=26) is 3.9%, but a few specimens identified as D. yukonensis from North America show a minimum distance of even less, 3.6%. Differential diagnosis. Adults of D. aericepsellus are most similar to D. aericeps Thomson, but are distinguished by the following characters: smaller body size (similar to D. elderi Kincaid, 1900, or smaller); very short, strongly narrowing postocular area; glossy metascutellum with few distinct pits and setae (3-6); pectus without distinct pits; and thorax black, including tegulae (based on the barcoded specimens: 1♀ 2♂). Lateral postocellar furrows very distinct in both sexes (Fig. 9F), like in D. aericeps and D. incisus. The thorax of female D. aericeps is usually largely red, whereas in the D. aericepsellus paratype female it is almost entirely black. Dolerus aericeps ab. nigricollis was described by Lindqvist (1943) from northern Finland close to the localities where D. aericepsellus was collected. We examined the type specimen of Dolerus aericeps ab. nigricollis deposited in the MZH and found that it is not conspecific with D. aericepsellus but with D. aericeps, although it has a nearly completely black thorax, with two obscure reddish flecks. Some other examined specimens of D. aericeps from northern Finland show reduced red markings on the thorax, suggesting that this character varies in D. aericeps. Type material. Holotype ♀.

Notes. The species boundaries between willow-feeding taxa of the Empria immersa group (E. immersa, E. camtschatica, E. plana, and E. improba) have proved to be difficult to elucidate (Prous et al. 2014, 2020). In Fennoscandia, two forms can commonly be found at the same time and place (Prous et al. 2014): E. immersa with a dark pterostigma and short antenna, and E. camtschatica with a pale pterostigma and long antenna. These two forms can also be distinguished by larval morphology (Fig. 22). Based on ex ovo rearings by M. Prous (two females from Sweden and Estonia) and ex larva rearings by Ponomarev (2022) of E. immersa, and ex ovo rearings by M. Prous of E. camtschatica (using two females from Sweden), the main difference seems to be in head coloration: E. immersa with an occipital fleck or stripe (Fig. 22F-M) and E. camtschatica with occipital and parietal stripes (Fig. 22A-E). An additional difference may be that glandubae (white conical warts) are more prominent in E. immersa than in E. camtschatica. Although based on limited specimen sampling, genome scale data (Prous et al. 2020) support E. immersa as a distinct species most consistently compared to the other species in the E. immersa group. In Fennoscandia, taxonomy is complicated by the presence of occasional specimens identifiable as E. plana, somewhat intermediate in morphology between E. immersa and E. camtschatica (pterostigma like E. camtschatica, saw intermediate). Genome scale data of one E. plana female from Sweden do not indicate affinity with E. immersa, but do show at least some affinity with E. camtschatica (Sweden), E. improba (Canada), and one other E. plana (Hokkaido, Japan) (see fig. 5 in Prous et al. 2020). Given the above, we synonymize E. plana and E. camtschatica with E. improba, because clear boundaries between these taxa cannot at present be drawn. Thus, in Europe, the specimens with dark pterostigma, short antennae and more prominent serrulae of the saw can be identified as E. immersa, and those with pale pterostigma, usually longer antennae, and less prominent serrulae as E. improba (see Prous et al. 2014). In North America, however, at least some E. improba specimens look externally more like E. immersa (dark pterostigma and metafemur), while the serrulae of the saw resemble E. camtschatica. Lacourt (2020) suggested that E. camtschatica could be a synonym of E. improba, but genetically these taxa are not necessarily closer to each other than they are to E. plana (Prous et al. 2020). If the circumscription of E. improba as proposed here is considered incorrect, then it remains unclear how many additional species should be recognized, and how these should be delimited. For example, in Europe the morphological distinction between E. camtschatica and E. plana is not clear, although these forms can be more reliably distinguished from E. immersa., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Smith, DR, 1979.

To help resolve the taxonomic disagreements in the interpretation of these nominal taxa, and promote the future stability of nomenclature, a neotype is designated for Astatus punctatus: Astatus punctatus Klug, 1803.

Germany, Brandenburg, Landkreis Märkisch-Oderland, Müncheberg, Trebnitz, 52.535°N, 14.204°E, damp meadow, swept from Alopecurus pratensis, 16.05.2015, leg. A. Liston (deposited in the SDEI). Labelling [printed on pale paper if not stated otherwise]: "Germany: Brandenburg; Landkreis Märkisch-Oderland, Müncheberg Trebnitz 16.05.2015 leg. A. D. Liston", “21255” [handwritten] with part of a leg gummed to card], “DEI-GISHym21255”, "♀ Calameuta punctata (Klug) [handwritten] det. A. Liston 2018", "NEOTYPE ♀ Astatus punctatus Klug, 1803 designated A. Liston 2022" [red]. Klug’s description states that abdominal segment 4 has obscure, paired dorsal spots; segment 5 four separate yellow spots, one pair laterally, the other dorsally; segments 6 and 7 with spots on their lower posterior margins; segment 8 immaculate; segment 9 completely yellow. Accordingly, we selected as neotype a specimen with small pale markings on terga 4-7 as well as 8-10 (Fig. 4A-D). The abdomen of a second female (DEI-GISHym21260) collected at the same place and time has fewer and less extensive pale markings and is thus intermediate in this respect to other female C. punctata specimens collected in Germany and all known Finnish and Estonian specimens, which have a completely black abdomen apart from terga 8-10 (Fig. 3A, C). Astatus floralis and A. analis have in the past generally been treated as synonyms of Calameuta haemorrhoidalis auct. [our Calameuta variabilis], e.g. by Konow (1905a). The opinion that A. floralis is a synonym of Cephus pygmeus (Linnaeus, 1767), as in de Dalla Torre (1894), cannot be accepted: Klug’s description of leg colour does not fit C. pygmeus. Our reason for placing A. floralis and A. analis as synonyms of Calameuta punctata rather than of C. variabilis is based primarily on one of the main characters which distinguishes C. punctata from C. variabilis: the structure of the maxillary palps. In the description of Astatus which precedes the descriptions of A. floralis, A. analis and A. punctatus, Klug characterized the genus thus: "Palpi[...]anteriores[...]sexarticulati, articulis duobus baseos cylindricis, aequalibus, tertio crassiori, longiori, subcylindrico, quarto longissimo, graciliori, quinto brevissimo, ultimo longitudine fere tertii subulato[...]". The described proportions of maxillary palpomeres 5 and 6 therefore fit C. punctata (Fig. 3D), not C. variabilis (Fig. 5B). Calameuta variabilis is unique in Calameuta in having maxillary palpomeres 5 and 6 of almost equal length (Gussakovskij 1935; Benson 1968; Zombori 1978). Zombori (1978) correctly identified Calameuta variabilis [which he called C. haemorrhoidalis] as a taxon distinct from C. punctata, and summarized the characters that distinguish them, but interpreted some of the names wrongly. Notably, Zombori (1978) did not mention the major contradiction in the morphology of the maxillary palps, as described by Klug, when he tentatively suggested that A. floralis and A. analis might be synonyms of Astatus haemorrhoidalis auct. ["the description of the latter two [Astatus floralis, Astatus analis] rather corresponds to the one given by Fabricius for C. haemorrhoidalis, accordingly, they are considered as synonyms of the latter name."]. Zombori’s main reason for doubting that Astatus analis was synonymous with Calameuta punctata, seems to have been the wording of Klug’s descriptions, which suggested that the thorax of Astatus analis is shinier than that of Calameuta punctata. Apart from this, Klug’s description of A. analis fits the darker forms within the rather wide range of variability in the female sex of C. punctata. Strangely, in his discussion of these names, Zombori (1978) does not mention Calameuta filum at all. The explicit collection data given by Klug (1803) for Astatus floralis ("Locus in editioribus argillosis; in floribus"), A. analis ("Locus in editioribus; in floribus"), and A. punctatus ("Locus in floribus") are, in part, not easy to interpret. Clearly, "in floribus" means that the specimens were collected from flowers. We think that "in editioribus argillosis" refers simply to the type of locality, i.e. an elevated place on clayey ground. This fits well with the type of sites at which C. punctata has recently been collected in Germany (see below). The synonymy of Calameuta filum with C. punctata can be proposed with a high degree of confidence. The characters described by Gussakovskij (1935) for the former are precisely those used by Zombori (1978) to characterize the latter. The same characters are also given by Viitasaari (1975) in his description of Finnish specimens identified as Calameuta filum, and which he compared with a syntype of that species. Viitasaari (1984) subsequently noted that Calameuta punctata sensu Zombori (1978) and C. filum are probably conspecific. Biology and distribution. The only recorded host plant of Calameuta punctata is Alopecurus pratensis L. (Vikberg 1978; Liston 2015), on which it is possibly monophagous. Accordingly, C. punctata occurs mostly in rather moist places. Its wider geographic range is not entirely clear, particularly because the identity of Calameuta pravei (Dovnar-Zapolskij, 1926) remains unresolved. This has been considered to be a valid species (e.g. Llorente and Gayubo 1990), or a synonym of C. punctata (e.g. Taeger et al. 2010). Calameuta pravei was recorded by Gussakovskij (1935) from Transcaucasia, Crimea, and the western Kopet-Dagh (Turkmenia). Llorente and Gayubo (1990) added records from Spain. Excluding these records, C. punctata is known from south-east Russia, Transcaucasia and south Siberia to Irkutsk (Gussakovskij 1935, as Cephus filum), and central and northern Europe (specimens examined by us). The distribution of C. punctata is therefore rather different from that of C. variabilis (see below), but their ranges overlap at least in parts of south-central Europe. Calameuta variabilis [as C. haemorrhoidalis auct.] has been stated to occur in Germany based on the mention of Germany as the type locality in the original descriptions by Fabricius (1781) of Tenthredo haemorrhoidalis and by Klug (1803) of Astatus punctatus, A. floralis and A. analis, coupled to an apparently faulty understanding of which taxa are represented by these names. Blank et al. (1998, 2001) listed C. haemorrhoidalis from Germany, only for Berlin-Brandenburg, dating the record respectively as "vor 1803" and “1802”. This refers to the type material of Klug’s species. Later, Liston et al. (2012) treated C. haemorrhoidalis auct. [C. variabilis] as extinct in Germany, and added C. punctata to the German list, based on recently collected specimens. Although it cannot be ruled out that C. variabilis once occurred in Germany, but has since disappeared, we think it more likely that in historical times only C. punctata ever occurred there, and propose in future to include only it in the list of German Symphyta. Fennoscandian and Estonian specimens which were previously identified as C. filum also belong to C. punctata. Based on COI sequences, C. punctata is split into two barcode clusters. Three specimens from Finland and one from Estonia are identical (BOLD:ACQ7596), but differ from two German specimens by 5.0-5.5% (no BIN assigned yet, GenBank accessions MW353981 and MW353982). The BOLD:ACQ7596 is closer to C. pallipes, differing by a minimum of 4.1%., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Zombori, L, 1978.

The color form of Dolerus gessneri with a red-banded abdomen was described as a distinct species, D. labiosus Konow, 1897 (Konow 1897b), but was later mostly treated as a synonym (sometimes also as a subspecies) of D. gessneri, because intermediate color forms with variable red markings on the abdomen occur. The specimens from the Russian Far East with completely black forelegs, which have sometimes been determined as D. gessneri, probably belong to some other Dolerus (subgen. Equidolerus) species. Dolerus gessneri, a Holarctic species, needs a revision, because COI barcoding data suggest that it could include more than one species, and some morphological characters correlate with the genetic data. There are three BIN clusters (BOLD:AAL2317, BOLD:ACE7304, BOLD:ACE3617) diverging by 1.8-2.3%. BOLD:AAL2317 is closest to D. timidus and BOLD:ACE7304 is closest to D. pratensis (minimum divergence in both cases 1.2%).

Fenusa ewaldi was described from two females reared from leaf-mines on Rosa collected in Novosibirsk, West Siberia (Smith and Altenhofer 2011). Also reared from Rosa by Ponomarev (2022): Russia, Moscow oblast, Voynovo-Gora, 55.846°N, 39.063°E, 10.07.2020. Since at least 2018, leaf-mines of Fenusa ewaldi have been frequently found on Rosa, e.g. R. woodsii and R. acicularis in Oulu Botanic Garden, and numerous females reared (Fig. 36). At these three localities, cultivated Rosa species in parks and gardens were the hosts (Fig. 37A). Mines were found mostly on more sheltered rose bushes. The rearing of four females from leaf-mines on Rubus chamaemorus (above) was therefore unexpected, considering the habitat was shady, moist, natural old-growth mixed forest dominated by spruce (Fig. 37B)., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Smith, DR, Altenhofer, E, 2011.

Dolerus incisus Goulet, 1986 Fig. 20A-C Notes. Finland: Regio kuusamoensis, Kuusamo Siikauopaja, YKJ grid coordinates: 7362:3612 [66.334°N, 29.511°E], 2♀ (ZMUO.035155, ZMUO.035156), 12.06.2018. 1♀ (ZMUO.045265), 20.06.2020. All specimens leg. M. Mutanen. ZMUO. First record in the Palaearctic. Recorded previously only in boreal North America: Alaska, Alberta, Yukon, and North West Territories (Goulet 1986). The genetic and morphological affinity of D. incisus to D. junci and D. yukonensis suggests that the host plant of D. incisus is also a species of Equisetum (Goulet 1986). The habitat in Finland is a shallow oxbow lake (meander) of the Oulanka river with plenty of Equisetum fluviatile, which is also the host of D. junci. This habitat matches perfectly with that given for D. incisus in North America by Goulet (1986). Several other Dolerus species occur syntopically, including the closely related D. junci Stephens (= D. cothurnatus auct., see above). The melanic form of D. incisus is recorded from Finland (all three are females, see above, Fig. 20A) and Norway (Heimdalsmunnen, alt 1150 m, leg. E. Heibo, CEH). Melanic females of D. subarcticus (recorded from Norway and Kamtschatka, see under D. subarcticus) can be distinguished by their postocellar furrows, the sawsheath (valvula 3) shape, and its apical setation (Fig. 20B). Melanic males can be separated most reliably by their penis valves (Fig. 20C, 20D). Only the melanic colour form of D. incisus has so far been recognized from Fennoscandian countries, whereas in Canada and the USA both the black color form and a form with red-banded abdomen and partly reddish legs are known.

Dolerus yukonensis has a Holarctic distribution, and both red-banded/-marked as well as melanic color forms occur. According to Goulet (1986) the color forms developed independently in the coastal areas of both continents. This speaks against the subspecific status of the melanic color forms suggested by Benson (1959). According to Benson (1934a) D. scoticus Cameron can be distinguished from melanic forms of D. yukonensis by the strongly developed temporal furrows, like in D. junci and D. incisus, which are absent in D. yukonensis. He also wrote that " Dolerus totus Malaise, 1931, from Kamtchatka may be the same species as D. scoticus Cam." Benson (1934b) synonymized them (and D. arcticola Kiaer, 1898) with D. scoticus and later all of them with D. yukonensis (Benson 1958: corrigenda). Latterly, he regarded D. scoticus as a subspecies of D. yukonensis (Benson 1959) and reported it from Switzerland (Benson 1961) and southern Norway, Hallingskarvet District (Benson 1966). However, Benson was not aware of the presence of melanic forms of D. incisus and D. subarcticus in Norway, the males of which can most reliably be identified by their penis valves (Fig. 20C, D). The sculpture of the abdominal terga in D. yukonensis, as in D. subarcticus, is not as stable as is often assumed. The depth of the clypeus emargination and the lateral postocellar furrows also vary. However, no potential male of D. scoticus, which could support its status as a distinct species as proposed by Haris (2000), has so far been recognized. The lectotype female of D. scoticus probably belongs to D. yukonensis, and certainly not to D. junci or D. incisus. Here we retain the synonymy of D. scoticus with D. yukonensis proposed by Benson (1958) and concurred with by Goulet (1986), but admit that more DNA sequence data are needed to test the taxonomic status of the melanic forms, which show at least some coinciding structural differences. We have studied melanic and red-marked color forms from the Palaearctic, but only red-marked forms from the Nearctic., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Ross, HH, 1931.

Chambers (1961): Potentilla reptans recorded as host of larva. Biology. ZMUO specimens, from Finland, are not reared; Sanguisorba, recorded as a host plant by Benson (1952), can be excluded as a possible host plant at these localities, but Potentilla erecta is present in abundance at one of the localities in Eastern Finland. Taxonomic notes. Konow (1886a), in a key, described the tibiae of Claremontia confusa (as Blennocampa confusa) as mainly black with only the knees very narrowly whitish and the protibia only whitish on the anterior face, and wrote that the tibiae of C. puncticeps were mainly pale. Benson (1952) and Lacourt (2020), among others, distinguished Claremontia brevicornis (as Claremontia confusa) from C. puncticeps using several characters, also including the color of the metatibia of females. However, Brischke (1883) described the metatibia of Claremontia brevicornis, a nominal species not known to Konow (1886a), as extensively yellow-white. Numerous barcoded females (SDEI, ZMUO) belong to two separate COI sequence clusters (distance 3.1-5.8%), which correlate fully with their leg color. Accordingly, we think that the original description of C. brevicornis refers to what has more recently come to be known as C. puncticeps, and that the correct name for the other species is C. confusa. Unlike some previous authors, we did not detect a clear difference in the sculpture of the head of the two forms. Distinction of the males is problematic, because of the lack of reliably identified male specimens of C. confusa. Benson (1952) stated that C. confusa "is entirely parthenogenetic, at least in Britain". On the other hand, several male specimens of C. brevicornis (Fig. 7C) have been barcoded, and can thus definitely be associated with that species. Based mainly on barcode-sequenced specimens in ZMUO, females of Claremontia confusa and C. brevicornis may be separated as follows.

Phymatoceropsis Rohwer, 1916 Phymatoceropsis Rohwer, 1916: 107-109. Type species: Phymatoceropsis fulvocincta Rohwer, 1916, by original designation. Dicrostema Benson, 1952: 97-98, 101. Type species: Selandria gracilicornis Zaddach, 1859, by original designation. Smith (1969): synonymy with Paracharactus. syn. nov. Description. Antennal flagellomeres proportionately narrow; flagellomere 1 3.2-4.7 × as long as distal width; the basal flagellomeres not widening distally, and setae normal (not long and coarse as in Phymatocera). Outer orbit with pronounced groove behind nearly whole length of eye. Postgenal carina developed slightly below eye (clearly in P. sibiricola, but very weakly in P. gracilicornis). Posterior of mesoscutellum with some conspicuous pits. Epicnemium variably developed, e.g. present in P. sibiricola, absent in P. gracilicornis. Claws with a small to minute inner tooth. Stub of 2A + 3A (Astatus analis) of fore wings straight, curved towards anterior, or furcate at apex; hind wing with enclosed cell M. Diagnosis. Phymatoceropsis can be distinguished from Rhadinoceraea by its proportionately narrower flagellomeres (flagellomere 1 3.2-4.7 × as long as distal width in Phymatoceropsis, 2.6-3.1 × as long as distal width in Rhadinoceraea); basal flagellomeres not distally widened (widened in Rhadinoceraea); outer orbit with pronounced groove behind whole length of eye (in Rhadinoceraea, if a groove is present, then this is behind only part of the eye. Phymatoceropsis differs from Lagonis in its mainly smooth mesepisternum (upper mesepisternum of Lagonis with numerous, large, crater-like pits). Phymatoceropsis can be separated from Paracharactus (based on North American species and the European P. hyalinus) by the mesoscutellum having at least a row of deep, well-defined pits on the posterior part (mesoscutellum entirely without pits in Paracharactus). Although in all examined specimens of Phymatoceropsis the stub of 2A + 3A of the fore wing is apically furcate (as is also usual in Rhadinoceraea), and in most specimens of various Nearctic Paracharactus and the European P. hyalinus (Konow, 1886) (Konow 1886a) the apex of 2A + 3A is straight, in some individuals of Nearctic Paracharactus species, as already noted by Smith (1969), it is furcate / curved strongly upwards, e.g. in P. rudis (Norton, 1861). Comments. The phylogeny of the Blennocampinae (Fig. 27) requires additional study, including analysis of genetic data obtained from a larger number of taxa. The large number of genus names currently in use as valid (Taeger et al. 2010 listed over 100), and their often weak morphological characterization, lead us to suspect that significant “oversplitting” may have occurred. However, at present it seems reasonable to retain Phymatoceropsis as valid, and to place P. sibiricola and P. gracilicornis there. The synonymy of Phymatoceropsis and Dicrostema is based on the close genetic similarity of the type species of Dicrostema to Phymatoceropsis sibiricola, and because these two species possess the same combination of characters exhibited by other Phymatoceropsis species, including its type species. The host plant ranges of lineages of the Phymatocerini may correlate to a certain degree with their phylogeny. As far as is known, Rhadinoceraea species are attached to Iridaceae and Liliaceae (Smith 1969), and Phymatoceropsis species to Adoxaceae, i.e. P. gracilicornis on Adoxa, and P. japonica and P. sibiricola on Sambucus. Interestingly, Sambucus species are also the hosts of Lagonis nevadensis, and L. opacicollis, which genetically also group with Phymatoceropsis, albeit with weak statistical support (Fig. 27). Unfortunately, the hosts of Paracharactus species are not known for certain. Smith (1969) reasoned that North American species might be attached to Carex, based on a tentative identification of a larva, whereas Lacourt (1985) speculated that the West Palaearctic P. hyalinus feeds on Ranunculus aconitifolius and R. platanifolius, without presenting any supporting data or observations. On the other hand, Okutani (1967) recorded the East Palaearctic Paracharactus leucopodus Rohwer, 1910 from Smilax (Liliales, Smilacaceae), but confirmation of this would be desirable. Both European Phymatoceropsis species are univoltine, as are probably nearly all Phymatocerini. Possible exceptions are Eurhadinoceraea ventralis (Severin 1997) and Phymatocera aterrima (Chevin and Silvestre de Sacy 2001), but the prolonged phenological periods of activity recorded for these species may be the result of polymodal emergence of adults, rather than true plurivoltinism., Published as part of Liston, Andrew, Mutanen, Marko, Heidemaa, Mikk, Blank, Stephan M., Kiljunen, Niina, Taeger, Andreas, Viitasaari, Matti, Vikberg, Veli, Wutke, Saskia & Prous, Marko, 2022, Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta), pp. 151-218 in Deutsche Entomologische Zeitschrift 69 (2) on page 151, DOI: 10.3897/dez.69.84080, {"references":["Smith, DR, 1969.

Synonymy with E. nigrans Konow by Liston et al. (2006). Notes. COI barcodes of a few specimens identified as E. nigrans are indistinguishable from those of a large number of E. ephippium (red-marked females). Vikberg et al. (2011) discussed the distribution of the two forms in Fennoscandia and more widely in Europe, noting that the patterns of occurrence are complex, and that they are regionally often sympatric, but that the dark form becomes more common towards the West, suggesting that climatic causes may play a role in maintaining this polymorphism. No other differences have been detected between the red-marked and black forms.
