Ordo: Hymenoptera

Genus: Antrocephalus
Name
Antrocephalus neogalleriae Narendran & van Achterberg, 2016 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype, ♀ (RMNH), “S. Vietnam: Dóng Nai, Cát Tiên N. P., Dong trail, Mal. traps, c. 100 m, 1–8.iv.2007, Mai Phu Quy & Nguyen Tanh Manh, RMNH’07”.
Diagnosis
This new species does not come close to any of the Oriental species of Antrocephalus described so far (Narendran 1989[1], Narendran and Sudheer 2005[2]). It runs to Antrocephalus galleriae Subba Rao and Antrocephalus maculipennis Cameron in the key by Narendran (1989)[1] but differs from them as follows: from Antrocephalus galleriae in having 1) metasoma distinctly shorter than mesosoma (in Antrocephalus galleriae metasoma distinctly longer than mesosoma); 2) metasoma 1.35 × as long as broad in dorsal view and not very acuminate posteriorly (in Antrocephalus galleriae metasoma 3 × as long as broad in dorsal view and acuminate posteriorly) and 3) fore wing with two infuscations (in Antrocephalus galleriae infuscations of fore wing absent).
This new species differs from Antrocephalus maculipennis in having: 1) pronotum with anterior carinae and tubercles absent (in Antrocephalus maculipennis pronotum with distinct anterior carinae and median tubercles); 2) PMV as long as MV (in Antrocephalus maculipennis PMV 1.5 × as long as MV) and 3) metasoma not acuminate posteriorly (in Antrocephalus maculipennis metasoma acuminate posteriorly.
Description
Holotype, ♀, length of body 4.8 mm.
Colour. Black; eyes pale gray, ocelli pale reflecting gray; antenna black except pedicel; anellus and F1 light pink; maxillary stipes and galea pale yellow; maxillary palp pale brown; teeth of mandibles dark brown; tegula dark brown basally separated from pale yellow distal part by a pink brown median part; all coxae and hind femora black; for femur, mid femur and mid tibia yellowish red; fore tibia and hind tibia brownish red; fore and mid tarsi pale yellow, hind tarsi reddish brown; all telotarsi dark; remaining parts of mesosoma and metasoma black; wings hyaline with two dark brown infuscation: one behind MV and other distal to STV; MV and STV black, PMV brown, SMV pale yellowish brown.
Head. Width of head 1.2 × its height in anterior view, 2.2 × as wide as long in dorsal view, subequal to width of mesosoma; scrobe reaching anterior ocellus, cross striate; pre-orbital carina running upwards joining each other behind anterior ocellus; post-orbital carina running upwards to vertex; malar ridge and auricular carinae present; eyes with widely scattered minute pubescence; malar space 0.5 × eye height in profile; eye length 0.7 × eye height in profile; geno-temporal furrow absent; POL 4. 8x OOL; AOL twice OOL; LOL subequal to OOL; width of interocular distance twice POL; each posterior ocellus with a characteristic deep pit attached to it; face and vertex with deep close setigerous pits; face and gena with moderate pubescence; scape reaching anterior ocellus; relative L:W of antennal segments: scape = 31:5; pedicel = 8:4; F1 = 7:5; F2 = 7:5; F3 = 6:6; F4 = 6:6; F5 = 5:6; F6 = 5:6; F7 = 5:6; clava = 11:6.
Mesosoma. Pronotum with anterior transverse carina present only on sides, median part ecarinate; surface closely punctate with interstices narrow, ecarinate, rugulose; posterior margin of pronotum concave medially; spiracular part with dense silvery pubescence; mesoscutum similarly pitted as in pronotum; tegula rugulose and pubescent; scutellum closely punctate as in mesoscutum and pronotum; interstices narrow and rugulose with a median fovea; apex of scutellum weakly emarginate; axillae densely pubescent. Propodeum subhorizontal with distinct submedian carinae, surface areolate and punctate with dense silvery pubescence on either side.
Wings. Fore wing 2.9 × as long as wide, relative length of CC = 29; SMV = 21; MV = 6; PMV = 6; STV = 2.
Legs. Hind coxa with a prominent dorso-basal tooth; hind femur without an inner basal tooth, ventral margin bi-lobed, with a comb of teeth; hind tibia closely reticulate granulate.
Metasoma. Sessile, shorter than mesosoma (25:18); T1 a little exceeding middle of metasoma, with a pit basally, smooth and shiny; T2 to T5 micro-sculptured and rugulose with pubescence on sides; T6 densely rugulose and punctate, fully pubescent, 1.5 × as long as epipygium; visible part of ovipositor sheath in dorsal view 0.5 × length of epipygium.
Male. Unknown.
Host
Unknown.
