Description
Lectotype of Allantus dorsatus ♀ (Fig. 11), additions based on other specimens are given in brackets [ ].
Body length 11 mm. Greenish yellow, following parts black: apex of each mandible; antennae entirely (Fig. 14); supra-antennal tubercle, frons and adjacent area of upper inner orbit except a short stripe on frontal ridge, postocellar area, a broad band from upper hind corner of each eye to postocellar area (Figs 12, 13); a medial band on pronotum; meso- and metanotum, except mesoscutellum and 2 small triangular spots on mesoscutal lateral lobe and 2 linear spots on mesoscutal median lobe (the latter sometimes absent); abdomen above, except for tergites 8–10 and posterior 2/5 of tergites 3–4; depressed upper corner of mesepimeron and a small and roundish spot in lower posterior corner of mesepisternum. Legs greenish yellow, following parts black: a small dot on extreme apex of each femur; a narrow dorsal stripe on fore and middle tibiae, dorsal side of hind tibia; a narrow stripe on fore and middle tarsi above (sometimes interrupted), hind tarsus entirely. Wings hyaline with faint yellowish tinge, veins and stigma pale brown, base of stigma slightly darkened. Body hairs silver. Body shiny; labrum and outer side of mandible with some large punctures, head otherwise almost impunctate, frontal basin feebly microsculptured; mesoscutal median lobe and mesoscutal lateral lobe sparsely punctured, interspaces smooth and shiny; posterior margin of mesoscutellum densely punctured, dorsal side of mesoscutellum hardly punctured; mesoscutellar appendage and parapsis impunctate; metascutellum with some minute punctures; mesepisternum shallowly but distinctly punctured, surface smooth, strongly shiny; metepisternum densely punctured, mesepimeron and metepimeron polished, with scattered punctures. Abdominal tergites 1–2 strongly shiny, tergite 3 weakly microsculptured in basal half, tergites 4–7 distinctly microsculptured and punctured in basal half.
Clypeus, labrum, mandibles as Fig. 11; ED = 1.3; supra-antennal tubercle distinctly smaller than scape (Figs 12, 13), clearly lower than top of ocelli in lateral view; a small tubercle present in bottom of middle fovea and in line with posterior margins of supra-antennal tubercles; frontal walls broad and flat, weakly divergent forwards; postocellar area broader than long as 7 : 5; lateral furrows deep, weakly divergent backwards; POL : OOL : OCL = 15 : 29 : 27; head behind eyes about 0.7 × length of eyes in dorsal view, indistinctly narrowed (Fig. 12); occipital carina distinct in lower 2/3 and rather weak in dorsal 1/3. Antennae weakly compressed, as long as head and thorax combined, antennomere 3 0.9 × length of antennomeres 4 and 5 together, [antennomeres 6–8 1.5–2.4 × as long as broad (Fig. 14)]. Anal cell of hind wing with a very short petiole. Ovipositor sheath as long as fore tibia. [Lancet with 20 serrulae, serrulae 5–6 as Fig. 15].
Male. Body length 8 mm. Similar to female except head distinctly narrowed behind eyes in dorsal view, malar space slightly longer than diameter of median ocellus; pale stripe from upper inner orbit to postocellar area missing; subgenital plate rounded at apex; penis valve simple, valviceps weakly bent; harpe about 2 × as long as broad (see figs 678 and 680 in Saini 2007[3]).
Distribution
India: Himachal Pradesh, Jammu & Kashmir, Uttaranchal (Saini et al. 2006[4]); Pakistan: Islamabad (Togashi 1989[5]). It is ambiguous whether these records actually base on Tyloceridius dorsatus or on the new Tyloceridius stictocephalus. We studied material from Himachal Pradesh, Jammu & Kasmir and Uttaranchal. Referring to Muche (1983)[6], Saini (2007)[3] recorded Tyloceridius dorsatus also from Nepal and Bhutan, but Muche mentioned only 1 ♀ (!) from India (“Chaurengi” located in former Uttarpradesh).
Lectotype (Fig. 11): 1♀, “Himalaya, Plasow”; “Allantus dorsatus Mocs., India Oriental”; “Lectotypus Allantus dorsatus Mocs., design. A. Taeger, 1988” [red]; “Tyloceridius dorsatus (Mocs.), det. A. Taeger, 88”. (HNHM). Left antenna, apical 3 antennomeres of right antenna, right foreleg below femur, left middle tarsus, right hind tarsus and left leg below femur are missing.
Paralectotype. 1 ♀, “Himalaya, Plasow”; “Typus Allantus dorsatus Mocs.”; “Syntype [sic!] Allantus dorsatus Mocsáry, 1883. teste A. Taeger, 2011” [red]; “Tylocerus [sic!] gen. n. bituberculatus Cam., Malaise det. 1935”; “DEI-GISHym 10877” (HNHM, figs see http://dx.doi.org/10.6084/m9.figshare.781292).
Other specimens examined
1 ♀ (Figs 12–15), India, Uttaranchal (former N Uttar Pradesh), 5. 7. 1989, Rishikesh [30.117°N, 78.317°E], A. Riedel leg. (SDEI); 1♀ same data (see http://dx.doi.org/10.6084/m9.figshare.903712); 2 ♀♀, India, Kalatop, (H.P.), 8200’, 11.7.83, M.S. Saini (USNM); 1♀1♂, India, Himachal Pradesh, Kalatop, 2400m, July 1983, M.S. Saini collector, Tyloceridius dorsatus Malaise (!) (USNM); 1 ♀ 2 ♂♂, kept in NHRS, data unrecorded; 1 ♀ 1 ♂ India, Uttarakhand, Joshimath, 14.6.1983, leg. Balbir (NHRS, photo documentation by H. Vårdal).
Remarks
Saini (2007)[3] described both sexes and illustrated the lancet, penis valve and gonoforceps. This species is widely distributed at higher altitudes in Uttaranchal & Himachal Pradesh (Saini 2007[3]).
