3. Campoplex difformis sensu Aubert (MZL). This species does not belong to the difformis species group but it is C. deficiens Gravenhorst, 1829 sensu Horstmann. According to Horstmann’s collection, C. deficiens forms a group of its own, being characterized by the occipital carina in the ventral half not turned outwards, meeting the hypostomal carina at an acute angle at the base of the mandible; head and mesopleuron with strong punctures on a polished surface; propodeal carinae strong, with the area superomedia about 1.5 × as long as wide, open posteriorly and mostly striate; posterior margins of the female sixth and seventh metasomal tergites clearly concave (Horstmann 1979) (Figs 1, 2A–C)., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on page 5, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836, {"references":["Gravenhorst J.

Notes on the identification of species of the Campoplex difformis group In his original boxes at the ZSM in Munich, Horstmann arranged the species of Campoplex into ten groups: borealis, continuus, difformis, discrepans, deficiens, faunus, fusciplica, melanostictus, spurius, and tumidulus groups. Of these, only five (borealis, continuus, difformis, discrepans, and melanostictus groups) have been defined by Horstmann in his works (1985, 2000, 2008). Horstmann (1985) provided a key to European species belonging to the continuus, difformis, discrepans, melanostictus and spurius groups (the last one included in the melanostictus group in Horstmann (1985), but separated in Horstmann’s original boxes), which can be distinguished from the other European species of the genus Campoplex in having the occipital carina in the ventral half turned outwards, meeting the hypostomal carina at a right angle at the base of the mandible (Fig. 2E–F). Even if the demarcation between these groups is often difficult (Horstmann 1985), species of the difformis group are characterized by the mesopleuron with scattered and shallow punctures on a coriaceous background (i.e., Figs 3C, 4A–B, 4D, 5, 8B, 11B, 15B); posterior margins of the female sixth and seventh metasomal tergites only very slightly concave (Fig. 2D); hind tibia yellowish to red-brown, seldom proximally and distally slightly darker, rarely proximally with a light spot (in C. helveticus Horstmann, 1985 and C. hercynicus Horstmann, 1985); hind femur red (with the exception of C. helveticus and C. nigricanae Horstmann, 1980, with the hind femur brown to black); and hind coxa black (except C. canariensis Horstmann, 1980 that has a red hind coxa). In the difformis group, a few species can easily be recognized by the peculiar shape of the epicnemial carina. In Campoplex melanostoma (Strobl, 1904) (syn. C. anterior Aubert, 1960) and C. punctulatus (Szépligeti, 1916), the epicnemial carina is subventrally abruptly turned towards the ventral hind corner of the pronotum, forming a sharp angled keel (Fig. 4A–C), while it is subventrally more or less straight in the other species of the group (Fig. 4D–E); in C. bilobus (Thomson, 1887) and C. hinziator Aubert, 1980, the epicnemial carina is ventrally raised and divided into two distinct lobes, thus with a clear notch in the middle separating the two parts (Fig. 5A); in C. hercynicus, the epicnemial carina is strongly raised ventrally, gently rounded and slightly notched in the middle, its width ventrally clearly greater than its width subventrally (Fig. 5B); in C. unicingulatus, the epicnemial carina is evenly raised ventrally and submedially, its width in the middle approximately as high as the width of the fore basitarsus, and not divided in the middle (Fig. 5C). Females of the remaining species can be separated on the basis of the ovipositor sheath ratio.The ovipositor ratio is less than 1.4 (usually significantly less) in Campoplex tibialis and related species (Fig. 6A), while it is 1.4 or more in species related to C. difformis. In C. restrictor Aubert, 1960 and C. striatus Horstmann, 1985, the temples are strongly narrowed behind the eyes: imaginary lines connecting the outer side of the eye and temple intersect at the level of the scutellar groove (Fig. 4F), while in species strictly related to C. difformis the temples are not so narrowed: imaginary lines connecting the outer side of the eye and temple intersect at the level of the scutellum or just behind it (Figs 4G, 7; with the only possible exception of C. corsicator stat. rev., that has imaginary lines connecting the outer side of the eye and temple intersecting at the level of the scutellar groove or just behind it). Since the revision of the difformis group by Horstmann (1985), two new species have been described, Campoplex ocellanae Horstmann, 1993 and C. formosanae Horstmann, 2012, and a third one, C. psilopterus Gravenhorst, 1829, was recognized as belonging to this group by Horstmann (2000). According to Horstmann (1993), the identification of Campoplex ocellanae in his key led to C. parvus Horstmann & Yu, 1999 (syn. C. minor Horstmann, 1985). Campoplex ocellanae can be inserted at couplet 26 in Horstmann’s key (1985) as follows: 26a.Temples slightly narrowed behind eyes, imaginary lines connecting outer side of eye and temple intersect at the base of the metasoma (Horstmann 1985: fig. 5). Area superomedia finely coriaceous, not wrinkled; area petiolaris anteriorly coriaceous, posteriorly finely striate; area superomedia and area petiolaris slightly depressed (Horstmann 1985: fig. 15). Body length about 4 mm............................................................................................ C. parvus Horstmann & Yu, 1999 – Temples comparatively more narrowed behind eyes, imaginary lines connecting outer side of eye and temple intersect behind the middle of the mesoscutum (Horstmann 1985: fig. 6; Horstmann 1993: fig. 4)................................................................................................................................... 26b 26b.Area superomedia and area petiolaris coriaceous and finely wrinkled; area petiolaris in addition with fine transverse wrinkles (Horstmann 1985: fig. 16). Body length about 6 mm................................................................................................. C. sulcatus Horstmann, 1985 – Area superomedia coriaceous and wrinkled only at the lateral margins; area petiolaris entirely and strongly striate, slightly depressed (Horstmann 1993: fig. 8). Body length about 5 mm................................................................................................. C. ocellanae Horstmann, 1993 Campoplex formosanae and C. psilopterus belong to the subgroup of closely related species, together with C. difformis, C. capitator, C. dubitator, and C. unicingulatus, which form a tricky complex of very similar species that are better characterized by their host association (Horstmann 2012). Campoplex psilopterus was described from a male by Gravenhorst (1829: 508), probably based on a specimen not completely pigmented (“Suspicor, hoc individuum, coloribus nondum perfecte temperatis, necatum esse”). The species was then cited and redescribed by Ratzeburg (1852: 86), who also described the female and reported a record of Siebold of a male and a female obtained from a species of Psychidae. According to Horstmann (2000), C. psilopterus is near to C. capitator, but it differs in its smaller body size (about 4 mm), slightly narrower face and area petiolaris clearly depressed. With respect to Gravenhorst’s description, Ratzeburg added that the female ovipositor is ¼– 1 / 5 as long as the metasoma. Unfortunately, the original descriptions of Gravenhorst and Ratzeburg and the short note of Horstmann based on the male in Gravenhorst’s collection do not allow this species to be unequivocally characterized. Thus – following Taxapad (Yu et al. 2016) – C. psilopterus is treated here as species inquirenda. Campoplex formosanae was reared from the cherry-bark tortrix, Enarmonia formosana (Scopoli, 1763), in Germany. The species was first treated by authors as C. dubitator (in Tanigoshi & Starý 2003; Jenner et al. 2004, 2005, 2013; Jenner & Kuhlmann 2006; Hunt & Kuhlmann 2007; Hunt et al. 2008; Jenner & Roitberg 2009), while molecular-based studies indicated that it might be conspecific with C. capitator, as molecular differences between the two species were not significant (Hunt & Kuhlmann 2007; Hunt et al. 2008). However, laboratory tests showed that C. formosanae was unable to develop in Lobesia botrana, the selected host species of C. capitator, and small but constant morphological characters can be found to support C. formosanae as a species distinct from C. capitator and related species (Hunt et al. 2008; Jenner et al. 2013). According to Horstmann (1985, 2012), Campoplex formosanae has morphologically intermediate characters between C. dubitator and C. unicingulatus (Horstmann 2012). It differs from C. unicingulatus in having ovipositor sheath ratio 1.7–1.8 the (Fig. 8A) (ovipositor ratio 1.4–1.5 in C. unicingulatus) and the epicnemial carina slightly raised ventrally (at most as high as half the width of the fore basitarsus, Fig. 8B) (strongly raised ventrally, about as high as the width of the fore basitarsus in C. unicingulatus). He reports also that flagellar segments in the apical quarter of C. formosanae are “as long as or slightly shorter than wide” (Horstmann 2012), but actually flagellar segments in C. formosanae identified by Horstmann himself in NMS seem to be relatively longer than those of C. unicingulatus in Horstmann’s collection (Fig. 9D–E). It differs from C. dubitator in having the area petiolaris clearly depressed and almost entirely covered by transverse wrinkles, including the anterior half (Figs 8C, 10D and Horstmann 2012: fig. 7) (only granulate and with no transverse wrinkles in the anterior half and with fine transverse wrinkles in the posterior half in C. dubitator; see Figs 10C, 11C and Horstmann 1985: fig. 10). Notes on cocoons of the Campoplex difformis group Cocoons of the following species have been examined: Campoplex capitator (Fig. 12A), C. dubitator (Fig. 12B), C. formosanae (Fig. 12C–E), C. unicingulatus (Fig. 12F), C. punctulatus (Fig. 13A–B), C. restrictor (Fig. 13C–D), C. sulcatus Horstmann, 1985 (Fig. 13E), and C. melanostoma (Fig. 13F). Species of Campoplex are solitary koinobiont endoparasitoids, mainly of small moths belonging to families Coleophoridae, Gelechiidae, Pyralidae, Tortricidae, and Yponomeutidae (Aubert 1983; Horstmann 1980, 1985; Shaw & Aeshlimann 1994; Yu et al. 2016). They preferentially oviposit in larvae and complete their development killing the host as prepupa. Sometimes, when unusual larger hosts are attacked, the hosts are killed before they can reach the prepupal stage; also, a few species kill the host when it has pupated (Shaw & Aeshlimann 1994; Shaw et al. 2016; Broad et al. 2018); the parasitoid spins its own cocoon inside or outside the host’s remains (Leong & Oatman 1968; Shaw & Aeshlimann 1994; Athanassov et al. 1998; Shaw et al. 2016); in our samples, at least two species – C. formosanae and C. punctulatus – spin their cocoon both externally to the host’s prepupa remains (that are made by the host's final instar skin) or wait for the host to have pupated and spin the cocoon inside the host’s chrysalis (Figs 12C–D, 13A–B). Cocoons of Campoplex (Figs 12–13) are elongate, sub-cylindrical, with rounded poles; cocoon size is related to adult size, so that male cocoons are generally smaller than those of females; in the examined cocoons, the length is about 3 × (± 0.3) in females and about 2.6 × (± 0.1) in males, the maximum width being measured at the equatorial zone. The colour is quite variable, even within the same species, ranging from pure silky white to very dark brown or blackish, with different shades of colour. The CEB can be present or absent, even when looking at cocoons of the same species; when present, the band can be intense white or dark, or sometimes the cocoon appears bicoloured with two thin external dark bands and a lighter internal band. Thickness and texture are variable too, from very thin and translucent (like in C. capitator) to very thick and opaque, and from smooth to corrugated surface. The loosely woven outer layer can be reduced or thick, giving the cocoon a woolly appearance and hiding the surface details of the dense middle layer. In several species of Ichneumonidae and Braconidae there is seasonal dimorphism in the structure and robustness of the cocoon, with the overwintering one thicker, darker and tougher than the summer one (Shaw & Huddleston 1991; Quicke 2015). The cocoons of Campoplex we examined show an evident dimorphism, even if probably not related to seasonality; most of them are from spring-summer generations, which have not entered diapause. Thus, the cause of observed dimorphism has to be sought in the exploited host and host plant. For example, observing a conspicuous series of cocoons of C. capitator reared in the laboratory on Lobesia botrana collected on Daphne gnidium and on Vitis vinifera L. in Italy, we noticed a constancy in the structure and colour of the cocoons, without evident seasonal variation. However, it cannot be excluded that observed variation in other species is due to the presence of further sibling species that are difficult to separate on a morphological basis. Without a better knowledge of intraspecific variation, it remains extremely difficult to reliably assign specimens developed on different hosts and different places to the same taxon on the base of cocoon features and shapes., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on pages 5-10, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836, {"references":["Horstmann K. 1985.

4. Campoplex mutabilis corsicator Aubert, 1960 (MZL). This was reported by Horstmann (1985) as a synonym of C. tibialis. Following Horstmann (1985), specimens of corsicator in Aubert’s collection belong to neither tibialis nor related species, as they have an ovipositor ratio of about 1.6 (whilst tibialis in Horstmann’s collection has an index of about 1.3). Campoplex corsicator also has very short temples (temple in lateral view about 0.5–0.6 as long as the transverse diameter of the eye in C. tibialis) and the area basalis triangular, i.e., with lateral carinae bounding the area basalis converging posteriorly to a single point, then extended to a short longitudinal carina towards the base of the area superomedia (area basalis trapezoidal, i.e., with lateral carinae converging posteriorly, but not touching at the base of the area superomedia in C. tibialis) (see redescription below and Fig. 3)., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on page 5, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836, {"references":["Aubert J-F. 1960 a.

1. Campoplex mutabilis mutabilis (Holmgren, 1860) (MZL). The specimens bear red labels specifying that the identification was made from comparison with Thomson’s material in Lund. We studied two females in Aubert’s collection and, after comparison with C. difformis in Horstmann’s collection, we think they are likely C. unicingulatus as they have the epicnemial carina evenly raised ventrally and submedially, propodeum with the area superomedia and area petiolaris only slightly depressed and with fine transverse striae starting from the base of the area petiolaris, and an ovipositor ratio of 1.5–1.6 (ovipositor ratio slightly exceeding that stated for C. unicingulatus). In our opinion, this misidentification could be the reason that led Aubert to reject Horstmann’s interpretation of mutabilis as a synonym of difformis., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on page 4, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836

2. Campoplex mutabilis var. gracilis (Ulbricht, 1910) (MZL). Campoplex gracilis is a synonym of C. dubitator Horstmann, 1985 (Horstmann 1985). Specimens of C. gracilis in Aubert’s collection are actually C. difformis sensu Horstmann; two specimens in Aubert’s collection, one female and one male, have been correctly identified and labelled as difformis by Horstmann himself., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on page 5, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836, {"references":["Horstmann K. 1985.

Metasoma and ovipositor sheath black. Notes The examined specimen, which we designate as the lectotype, does not fit the description of Campoplex tibialis, as the ovipositor ratio is clearly greater than that of C. tibialis. Also, the specimen is characterized by the temple, in lateral view, at most 0.4–0.5 × as long as the transverse diameter of the eye and the propodeum with the area basalis triangular (as in Campoplex angustioranae (Bauer, 1937); Horstmann 1985). These reasons led us to remove C. corsicator from synonymy with C. tibialis (Horstmann, 1985)., Published as part of Giovanni, Filippo Di, Scaramozzino, Pier Luigi, Loni, Augusto & Lucchi, Andrea, 2021, Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance, pp. 1-35 in European Journal of Taxonomy 740 on pages 10-15, DOI: 10.5852/ejt.2021.740.1277, http://zenodo.org/record/4637836, {"references":["Aubert J-F. 1960 a.

Metasoma with tergite I black with apical spot yellowish-red, following tergites dark brown with apical margin yellowish-red, thyridia on tergite II, tergite VII and parameres yellowish-red. Wings hyaline, veins and pterostigma yellowish-brown. Diagnosis. The male of M. strumiai differs from the female (see Fig. 5���8 in Di Giovanni et al. 2018) in having metasoma not laterally compressed, postpetiole with few rugulose punctures and tergite II slightly longer than in female, slightly coriaceous at the base then polished with dense punctures, with thyridia strong; in the color pattern, it differs in having flagellum dark brown dorsally and reddish-brown ventrally, mesosoma mostly black, with scutellum apically and postscutellum reddish-brown and subalar prominence, ventral margin and dorsal hind corner of pronotum yellow, metasoma with abdominal tergites dark brown with apical margin yellowish-red, hind femur and tibia dark brown. According to the key to the European males of Misetus by Selfa & Diller (1995: 801), the male of M. strumiai can be keyed out with M. tyloidalis Kolarov, 1985, as it has hind femur dark brown and propodeum with area superomedia not defined, but it can be distinguished from the latter by its smaller size, antenna with 24���25 flagellomeres and tyloidae starting from 8 th flagellomere, temple shorter than eye width, mesopleuron covered with fine longitudinal striae, and metasomal tergite II basally slightly coriaceous-strigose. From M. nigritulus Kolarov, 1985 it differs by its smaller size and in having propodeum with costulae distinct only at the base, dorsolateral carina of postpetiolus weakly distinct, metasomal tergite II longer than apically wide, with thyridia separated from the base of the tergite to a distance longer than its width, and tegula yellow. From males of M. oculatus Wesmael, 1845, it can be separated by smaller size, antenna with only 24��� 25 flagellomeres, propodeum with area superomedia irregularly shaped, metasomal tergite II basally slightly coriaceousstrigose, scutellum apically and postscutellum reddish-brown, hind coxa and femur dark brown. Males of M. strumiai resemble in size, irregular shape of area superomedia and color pattern small specimens M. hispanator Selfa, 1995, but can be distinguished from this species by tegulae yellow, scutellum apically and postscutellum reddish-brown, hind femur and tibia entirely dark brown, metasomal tergite II basally comparatively less strigose, coriaceous in the middle.

Mandible about 2.5> as long as basally wide, teeth unequal, lower tooth clearly longer the upper one. Labial palps 4-segmented, maxillary palps 5- segmented, the first segment medially enlarged. Occipital carina complete, joining hypostomal carina at base of mandible. Antenna with 24 flagellomeres, first flagellomere about 2.1> as long as apically wide. Mesosoma. Pronotum smooth and polished, with just few undefined punctures on dorsal part and small fine wrinkles on anterior and posterior margins; epomia absent. Mesoscutum with dense punctures, notaulus deeply impressed in the anterior half; scutellum with dense punctures, without lateral carinae. Mesopleuron, except for smooth speculum, covered with fine longitudinal striae; sternaulus impressed in the anterior half of mesopleuron; epicnemial carina present and reaching anterior margin of mesopleuron; mesosternum coriaceous–punctate; posterior transverse carina of mesosternum complete but weak at level of middle coxa. Fore wing areolet regularly pentagonal; cu-a opposite Rs &M; length of Cu1 between 1m-cu and Cu1a about 1.7> as long as Cu1b. Hind wing with distal abscissa of Cu1 present; length of Cu1 between cu-a and M about 2.2> as long as cu-a. Coxae coriaceous–punctate, subpolished. Hind femur about 2.8> as long as maximum width. Propodeum coriaceous, irregularly wrinkled, with propodeal carinae weakly marked, with the exception of posterior transverse carina and pleural carina; area superomedia as in Fig. 7, about 1.3–1.4> as long as wide and with costulae originating from basal half of the area superomedia; area basalis not defined; area petiolaris strongly concave and transversally striate; metapleuron smooth in the anterior half, coriaceous and with irregular wrinkles on posterior half. Metasoma. Metasoma, seen from above, narrowed from tergite III to apex, covered with fine, short and sparse pubescence. Tergite I with dorsal longitudinal carinae weak, median and lateral parts of postpetiole not differentiated; postpetiole with few punctures medially. Metasomal tergite II about 1.3–1.4> as long as apically wide, thyridia weakly marked and separated from the base, placed at about 0.25 the length of the tergite; tergite II slightly coriaceous at the basal 0.1, then polished, with very few scattered punctures. Remaining metasomal tergites polished and without punctures; metasomal tergites V–VII only weakly emarginate apically. Ovipositor short and upcurved, ovipositor sheaths about 0.2> as long as hind basitarsus. Color. Head entirely black, with the exception of clypeus reddish-brown, mandible yellowish-red (except red teeth), maxillary and labial palps yellowish-white; scapus and pedicellus red, flagellum red with flagellar segments 5–9 whitish (seen from inner side). Mesosoma red (including scutellum and postscutellum), dorsal part of propleuron, anterior part of mesoscutum, metapleuron and propodeum somewhat darker; upper hind corner of propleuron, tegula and subalar prominence yellowish-white. Legs red, fore and middle coxae and all trochanters yellowish-red, hind femur slightly dark red on the apical half. Metasoma red, tergite II and III basally red, apically paler. Wings hyaline, veins and pterostigma yellowish. Male. Unknown. Etymology. The new species is named in honour of Franco Strumia, a renowned Italian expert of Chrysididae who collected the specimen, in recognition of his efforts in sampling the entomological fauna of Tuscany. Differential diagnosis. Misetus strumiai sp. nov. can be clearly distinguished by all the other species of the genus by having metasomal tergite II almost completely smooth and polished, slightly coriaceous only at the basal 0.1 and with few scattered punctures and clypeus with a small developed medial tooth. Other species of Misetus have metasomal tergite II longitudinally striate or wrinkled in the basal half, and usually more densely punctuate in the apical half, and clypeus with medial tooth strong and more developed (in M. hispanator relatively small but still clearly visible in frontal view). In addition: postpetiole with median and lateral parts not differentiated and with few punctures medially (median and lateral parts usually separated, or if weakly differentiated—as in male of M. tyloidalis —then more markedly striate); antenna relatively short, with fewer than 25 segments; propodeum with area superomedia longer than wide (area superomedia as long as wide in male of M. nigritulus); mesosoma, including scutellum, legs, including hind coxa, and metasoma entirely red (mesosoma in greater part black in other species; hind coxa redas in M. oculatus —or brown to black in other species; metasoma more or less brownish-black in other species, extensively red in some specimens of M. oculatus).
