Lobe of anterior mesopleural area absent and epicnemial pit open ventrally (Fig.18). Mesepimeral and transpleural sulci present; mesopleural carina and matt spot on mesopleuron above mesocoxa absent. All trochantelli present. Tegula, if present, covering lateral subapical lobe of humeral complex of fore wing base only partly. Fore wing, if present, with venation distinctly exceeding basal half of wing length (stigmal vein almost perpendicular to marginal vein, postmarginal vein present). Hind wing, if present, without closed basal cell. Median and lateral grooves present on T2 and S2; S2 without setose lines. S2 without basal cushion of setae; last sternite (S6) of female equal to or shorter than S3���S5 sternites combined. Remarks. The examined external morphological features and DNA sequence data support the allospecificity of Idiotypa maritima (Haliday) and I. mariae Gregor. Both species are widely distributed in Palaearctic from West Europe to Japan. Examination of the type material, the lectotype of I. nigriceps Kieffer, 1909 (the same specimen also the lectotype of I. nigriceps Kieffer, 1911), the lectotype of I. rufiventris (Thomson), and the lectotype of I. maritima (Haliday), clearly shows that these names are synonyms. The species Eunuchopria nitens Szab��, 1961, originally described in the monotypic genus Eunuchopria (Szab��, 1961), appears at first sight very different from Idiotypa, most noticeably by its aptery in both sexes, lack of ocelli, notauli, tegulae, axillae and axillar depressions; scutellum only visible as narrow transverse sclerite with only scutoscutellar sulcus between it and mesoscutum. However this is an expression of a common suite of reduction characters associated with extreme wing reduction and fossorial habits, which appears to have arisen commonly in several unrelated genera of diapriines. Similar extreme examples can be found in some undescribed species of Idiotypa from Chile and Argentina (Masner & Garcia, 2002), Spilomicrus myrmecophilus Nixon (females) and Platymischus dilatatus Westwood (both sexes). If these particular reductions are discounted the remaining features of E. nitens correspond well with diagnosis of the genus Idiotypa. We therefore consider E. nitens is simply a highly derived species of Idiotypa and Eunuchopria Szab��, 1961 is therefore a junior synonym of Idiotypa F��rster, 1856. Unfortunately the diagnostic characters of the species of Idiotypa are not universal in all parts of the Palaearctic region. The key below works well for the fauna of Europe (including the European part of Russia), Siberia and Russian Far East. While antennal characters of female I. maritima and I. mariae are difficult to appreciate, in combination with characters of the mesopleural sculpture and body colour, they can be used to make reliable determinations, however in Japan no combination of characters is consistent for species recognition., Published as part of Chemyreva, Vasilisa G., Notton, David G. & Zald��var-River��n, Alejandro, 2021, Revision of Palaearctic Idiotypa (Hymenoptera, Diapriidae, Diapriinae, Spilomicrini), pp. 127-144 in Zootaxa 4966 (2) on pages 129-130, DOI: 10.11646/zootaxa.4966.2.2, http://zenodo.org/record/4736399, {"references":["Ruthe, J.

Subspecies arabicum Ebmer, 2008 Lasioglossum (Evylaeus) villosulum arabicum Ebmer, 2008: 560. Holotype: ♀, UAE, Sharjah x Khor Kalba, 7–14 Jun. 2006, light trap, leg. A.V. Harten 6681 (SDEI). Examined by AP. Distribution This subspecies inhabits the Arabian Peninsula (Oman, UAE) and is distinguished mainly by red terga (Figs 13–14). Also conspicuous are the zones of snow white, felted, adpressed pubescence on the face, particularly on frontal area and pronotum, and white, felted, upstanding hairs on the mesopleura, particularly the front as well as the posterior propodeal surface and the lateral fields above. This pubescence marks the subspecies as a desert form (Ebmer 2008: 560; Dathe 2009: 385). Specimens from Oman and UAE have red terga, whereas those from Yemen, identified as L. villosulum by Ebmer (D. Notton, unpublished new record), have dark black terga. Maybe there is more taxonomic complexity here, but it is outside the scope of the current project to further examine this. It may correlate with topography and climate since Oman and UAE are generally lower altitude (hotter) and Yemen is generally higher altitude (cooler)., Published as part of Pauly, Alain, Noël, Grégoire, Sonet, Gontran, Notton, David G. & Boevé, Jean-Luc, 2019, Integrative taxonomy resuscitates two species in the Lasioglossum villosulum complex (Kirby, 1802) (Hymenoptera: Apoidea: Halictidae), pp. 1-43 in European Journal of Taxonomy 541 on page 22, DOI: 10.5852/ejt.2019.541, http://zenodo.org/record/3377625, {"references":["Ebmer A.

It is not the purpose of this paper to discuss the status and diagnosis of this subspecies, as little material is available for examination and no fresh material was available for DNA study. The subspecies is distinguished from the subspecies villosulum mainly by shorter and more rounded head and broader eyes. We have examined and photographed the heads of old specimens from the typical locality in Taiwan and preserved in the MNHUB and compared them with the heads of L. villosulum villosulum and L. medinai (Fig. 12).

However, Chambers (1981: as I. halidayi), but not Chambers (1955), which is in fact I. similis sp. nov., see below. Notes Kolyada & Chemyreva (2016) incorrectly state that Entomia campanulata is a nomen oblitum, however no action has been taken under Article 23.9.2 (ICZN 1999) to reverse the precedence with respect to I. halidayi so it cannot be a nomen oblitum. We follow Masner (1976) who doubtfully included in it synonymy with Ismarus halidayi and we consider that the interpretation of the species is doubtful and so the synonymy is also doubtful, and it is therefore a nomen dubium, i.e., although it is the older name, it is not certainly the valid name for the species referred to here as I. halidayi., Published as part of Kim, Chang-Jun, Notton, David G., ��degaard, Frode & Lee, Jong-Wook, 2018, Review of the Palaearctic species of Ismaridae Thomson, 1858 (Hymenoptera: Diaprioidea), pp. 1-38 in European Journal of Taxonomy 417 on pages 21-25, DOI: 10.5852/ejt.2018.417, http://zenodo.org/record/1211284, {"references":["ForsterA. 1850.

LeSage (sweep coastal vegetation— Macropiper sp.; CNCI). Comments. There are few data on the distribution of Aphanomerus. Perkins (1905), Brues (1908), Dodd (1914) and Kieffer (1926) found Aphanomerus only in Australia; Masner & Huggert (1989) confirmed the presence of Aphanomerus in Australia and recorded it also from New Zealand, New Guinea and Sulawesi; Vlug (1995) considered Aphanomerus to be an Australian and Oriental genus. Aphanomerus rufescens was described from Australia by Perkins (1905), and A. pusillus, Perkins was introduced from Australia into Hawai’i in 1904 as a biocontrol agent of Siphanta acuta (Walker) (Flatidae) (Fouts 1936; Lai 1988; Denoth et al. 2002; Gruner 2004). Aphanomerus pusillus was found in New Zealand (Gourlay 1930; Jamieson et al. 2009), where it was probably also introduced. We consider that Aphanomerus rufescens is not native, but introduced to the USA. The use of Aphanomerus (especially A. pusillus) in classical biological control of leafhoppers from the early twentieth century has likely contributed to its spread, though we have found no documentation that it was intentionally introduced into the United States of America. The descriptions of Aphanomerus rufescens (Perkins 1905; Dodd 1914; Kieffer 1926) were insufficient for reliable identification at species level, and consequently our determination was made only after examining photographs of the type specimen of A. rufescens Perkins (BPBM). Because of this, and because Aphanomerus contains parasitoids of some important pests (Siphanta) we consider it necessary to redescribe this species. Description. Female. Colour: head and mesosoma black; metasoma brown with T2 darker than the rest of tergites; head and mesosoma covered with silvery short hairs; legs including coxae, yellow with a reddish tint in some specimens; antenna with the same colour as the legs, but clava brown as in T2. Head in dorsal view wider that long, subellipsoidal with a coriaceous-imbricate sculpture and sparse long hairs; frons, above toruli, with an alutaceous sculpture; frons in the middle smooth almost without sculpture; occipital and hyperoccipital carina absent; postgenal sulcus and median sulcus of the postgenal bridge absent; postgenal pit present; eyes appearing glabrous, but under high magnification with minute, fine scattered hairs; malar sulcus absent, gena not striate; interantennal process not prominent; clypeus very narrow and short, not wider than the inter-mandibular space, with a row of strong and long setae; mandible bidentate; maxillary palp 2- segmented; labial palp 1-segmented; antenna 7-segmented, with abrupt, massive, compact 4-segmented clava, sensillar formula 1:2:2:1. Mesosoma with pronotal shoulders clearly visible in dorsal view, but not angular; mesoscutum and mesoscutellum with a clearly visible coriaceous-imbricate sculpture; skaphion and skaphion carina present, clearly visible; antero-admedian line and parapsidal line absent; notauli present, percurrent, rather superficial, not crenulate and convergent posteriorly; terminal, any notaulus with a conspicuous pit; transaxillar carina short but visible; axillular carina not visible; posterior scutellar sulcus deep and wide laterally, not visible medio-posteriorly; metanotum narrow, smooth, not foveolate; metascutellum not visible, overlapped by posteromedial margin of mesoscutellum; propodeum with no foamy structure, with some sparse hairs at sides, glabrous in middle, with clearly visible parallel lateral propodeal carinae; metasomal depression small, with some short hairs and a median carina; clearly visible propodeal spiracle; propodeum with a strong transverse carina posteriorly; along the posterior transverse propodeal carina there is a strong crenulate sulcus, interrupted by lateral propodeal carinae; transverse pronotal sulcus shallow and glabrous; lateral propleural area smooth and lustrous with some sparse hairs, without depression; netrion absent; transaxillar carina in lateral view with one or two striae; mesopleuron smooth, almost glabrous, with a shallow, rather absent mesopleural depression; pleural pit not visible; transpleural sulcus almost transverse, deep and sharply incised; speculum smooth, lustrous and glabrous; femoral depression small; mesopleural carina, present, clearly visible; metapleuron not sculptured, lustrous, rather glabrous, only ventrally near the posterior coxa with some sparse hairs; metapleural pit continuous with a clearly visible, deeply incised metapleural sulcus; metapleural carina, well developed; fore wing with a straight tubular submarginal vein, truncate knob and with nebulous Rs+M (but this is barely visible even on a microscopic slide at 400x); costal and submedian cells glabrous; submarginal vein without setae; hind wing with short stem of tubular submarginal vein; tibial spur formula 1-2-2 and with fore spur bifid. Metasoma no longer than head and mesosoma combined, hardly convex dorsally, with 6 visible tergites, terminally pointed; T1 trapezoidal, without horn; anterior pits of T1 clearly visible, the space between these pits with strong costae, the length of these costae not surpassing the posterior border of anterior pits of T1; laterally, in the area of the anterior pits, T1 is covered with sparse long setae, but in middle, in the area with sculpture it is glabrous; T2, the largest tergite almost rectangular, smooth, with anterior pits clearly visible; T3–T5 without sculpture, almost glabrous, with only a few sparse hairs; T6 well developed, triangular with sparse hairs; length of T6 the same as the combined lengths of T3–T5; laterotergites present, relatively narrow, almost 1/10 maximum width of S2; ventrally metasoma almost glabrous, with few sparse hairs on S1 and S6; anterior pits of S2 clearly visible without hairs; the felt field of S2 almost absent, indicated only by a hardly visible microsculpture. Male: with the same colour as female, but the head and mesosoma dark brown or brown. Differs from female in the antenna (8-segmented) and the shape and length of metasoma. Metasoma shorter than head and mesosoma together (length of head + length of mesosoma = 1.4–1.5× length of metasoma). T2 distinctly trapezoidal and apex of metasoma obtuse. Laterotergites 1/6 maximum width of S2 and wider than those of the female. Morphological variability. Usually intraspecific variability is shown in the colour of the metasoma, from dark to light brown. Usually the darkest tergite is T2, T1 being sometimes yellowish. Pilosity of T2 also varies, in some specimens the anterior pits of T2 being covered with a dense pilosity. In this case some sparse hairs can be seen on the lateral sides of T2, in contrast to specimens where the anterior pits of T2 have a few hairs and the rest of T2 is glabrous. The shape and size of T2 are also variable. In some cases T2 is long, with sides almost parallel so this tergite is almost rectangular. There are also specimens with T2 a shorter, with sides divergent and in this case the shape of T2 is almost trapezoidal (in these females, the shape of T2 is like the shape of T 2 in males). Although we did not make a rigorous statistical analysis, there was not a clear correlation between the variability of colour, size/ shape of T2 and overall size, and no suggestion of allometry.

The monotypic Tetrabaeus was previously only recorded from North America (Brues 1909; Kieffer 1912, 1926; Muesebeck 1963; Masner 1964; Vlug 1995). It is difficult to determine if T. americanus is a recently introduced species in the Palaearctic region or a native one that has been unrecorded until now. Masner (unpublished data), examined some specimens of this species in HNHM, collected from Hungary and labeled as Aphanomerus (as noted in the Results section, striae on T2 are usually present but difficult to see without good optics and are only rarely absent). These specimens are seemingly lost because OAP was not able to locate them in the HNHM during his recent visit. Because this species was also found in samples from Georgia, South Korea and Japan, we consider the possibility that Tetrabaeus is a Holarctic genus. Although the descriptions of Muesebeck (1963) and Masner & Huggert (1989) provide clear limits of this species, we here augment these descriptions with the addition of new data on variability and clear images of the morphology. Description. Female. Colour: Most specimens are black or dark brown, but also there are specimens with black head and mesosoma and dark brownish metasoma. Antenna light brown, in many specimens with yellow A3–A5 and brown clava, but in some specimens the entire antenna is light brown with a darker clava. Legs with coxae brown and tibiae and tarsi yellow; femora lighter than coxae and darker than tibiae and tarsi. Head in dorsal view wider than long, subellipsoidal with a coriaceous-imbricate sculpture and sparse long hairs; frons dorsal to toruli with alutaceous sculpture; frons medially smooth, almost without sculpture; hyperoccipital carina absent; occipital carina present, complete medially; postgenal sulcus and median sulcus of the postgenal bridge absent; postgenal pit present; eyes appear glabrous, but under high magnification with short, fine scattered hairs; interantennal process not prominent, deeply concave; clypeus very narrow, with a row of strong and long setae; maxillary palp 2-segmented; labial palp 1-segmented; antenna 7-segmented, with abrupt, massive, compact 4-segmented clava, sensillar formula 1:2:2:2. Mesosoma with pronotal shoulders strongly developed, clearly visible in dorsal view; mesoscutum and mesoscutellum with fine coriaceous sculpture; parapsidal line absent; notauli percurrent, deeply incised, broadened and convergent posteriorly; transaxillar carina and axillular carina not fused, both clearly visible; posterior mesoscutellar sulcus deep and wide, clearly visible on lateral sides of mesoscutellum, but superficial or absent on medio-posterior part of mesoscutellum; metanotum narrow, smooth, not foveolate; metascutellum hardly visible, with no sculpture or pilosity; propodeum with no foamy structure, hairy at sides, glabrous in middle, with two clearly visible, parallel lateral propodeal carinae; metasomal depression large, glabrous; propodeal spiracle clearly visible; transverse pronotal sulcus shallow and glabrous only in the median part, on ventral and dorsal third covered with short hairs; lateral propleural area with a large, deep and glabrous depression; netrion rudimentary, hardly visible; transaxillar carina in lateral view with numerous longitudinal striae; mesopleuron smooth, almost glabrous, with a clearly visible, rather deep mesopleural depression; pleural pit well visible; transpleural sulcus almost transverse, deep and sharply incised, interrupted in the median part; speculum with some transverse costae; metapleuron not sculptured, covered with sparse long hairs; clearly visible metapleural pit; metapleural sulcus weak; metapleural carina well developed; fore wing with a straight tubular submarginal vein and truncate knob and with nebulous RS+M, M and Cu (hardly visible); costal and submedian cells glabrous; submarginal vein without setae; hind wing with short stem of tubular submarginal vein, apically with some setae; legs relatively short with femora thickened; tibial spur formula 1-2-2 and fore spur bifid. Metasoma not longer than head and mesosoma combined, convex dorsally, with 6 visible tergites; T1 trapezoidal, without horn; anterior pits of T1 clearly visible, the space between these pits with strong costae, the length of these costae not surpassing the posterior border of anterior pits of T1; laterally, in the area of the anterior pits, T1 is covered with sparse long setae, but in middle, in the area with sculpture it is glabrous; T2, the largest tergite, smooth, with anterior pits clearly visible with some hairs; the space between the anterior pits of T2 with strong costae, protruding over T1; T3–T6 without sculpture, with few hairs, usually in a single transverse row; laterotergites present, well developed, almost ¼ maximum width of T2; ventrally metasoma with numerous hairs, especially on S1 and S2; anterior pits of S2 converging in a single transverse depression covered with dense hairs; the felt field of S2 indicated only by distinct microsculpture, not with dense pilosity. Male: similar to female, differing in the structure of antenna, clava less abrupt, limits between clavomeres more clearly marked than in female, A4 longer than A3 and metasoma consisting of 8 visible tergites with a rounded apex (apex rather obtuse in female). Our specimens represent a new record for the Palaearctic (Ukraine, Georgia and South Korea) and Sino- Japanese regions (Japan). Also, Tetrabaeus is a new record for Canada and Mexico (in the last case being found very close to the Panamanian region). Morphological variability. We consider that all of the examined specimens belong to the same species, T. americanus. We concluded this from a comparison of our specimens with specimens from the Nearctic. Regarding colour variability, we consider that the collecting method and preservation conditions (e.g. ethanol concentration, temperature, duration of time in trap) have an influence. The influence of the preservation conditions on the colour of insects was also emphasized by Noyes (1982), Masner (1994) and King & Porter (2004). Specimens in which the metasoma is paler also have this part of the body inflated, suggesting that these specimens have been bleached and distorted by prolonged storage in ethanol (O. Popovici, pers. obs.). We did not find a correlation between geographical distribution and colour. Another variable character we observed is the length of the costae on T2. The longest costae are in specimens from Canada and the costae are absent from a male specimen from South Korea. Masner & Huggert (1989) considered the sculpture of T2 important in the delimitation of the genera with 7 or 8 antennomeres, and with compact clava. The presence of the longitudinal costae/striae on T2 divide this group of genera into two subgroups: Pseudaphanomerus Szelényi, Calomerella Masner & Huggert, Aphanomerella Dodd and Tetrabaeus Kieffer, (costae present) and Aleyroctonus Masner & Huggert, Helava Masner & Huggert, Alfredella Masner & Huggert, and Aphanomerus Perkins (costae absent)., Published as part of Popovici, Ovidiu Alin, Masner, Lubomír, Viciriuc, Mădălina, Pintilioaie, Alexandru, Notton, David G. & Talamas, Elijah, 2018, New distribution data for some charismatic tramp species of Platygastroidea (Hymenoptera), pp. 1-22 in Zootaxa 4370 (1) on pages 6-10, DOI: 10.11646/zootaxa.4370.1.1, http://zenodo.org/record/1138484
