description: Agonischius lateritius Fleutiaux, 1940
(Figures 1, 28, 29, 32–37)
Agonischius lateritius Fleutiaux, 1940: 122 (original description; type locality: Sen Kam, Laos; key to Agonischius species from Indochina region); Platia, 2008: 6 (redescription), 12 (key to the known species of Agonischius), 22 (photo of male aedeagus), 25 (photo of habitus); Platia, 2009: 43 (new record from China).
Type material. Holotype: Male (Fig. 28), Sen Kam, Laos, 29/V/1918, R. Vitalis de Salvaza leg. (MNHN). Non type materials. 2 female (Fig. 29), Bao Loc, Lam Dong Province, Vietnam, IV/2004, by the native (CAR); 1 female, West Siang District, Arunachal Pradesh State, India, 4/VII/2011, T. Maeda leg. (CAR). Distribution (Fig. 1). India, Nepal, Myanmar, China (Guangxi Zhuang Autonomous Region), Laos, Vietnam, Thailand.
Additional description. Adults. Measurements. Male, holotype. BL: 11.5, BW: 3.42, PL: 2.92, PML: 2.56, PW: 3.27, PL/PW: 0.893, EL: 8.30, EW: 3.42, EL/EW: 2.43. Female. BL: 10.3–11.2, BW: 2.88–3.18, PL: 2.42– 2.69, PML: 2.12–2.33, PW: 2.88–3.12, PL/PW: 0.840–0.862, EL: 7.35–7.97, EW: 2.87–3.18, EL/EW: 2.51–2.56.
Female. Tergite VIII (Fig. 32) long shield-shaped (length/width = ca. 1.3), widest at basal 9/20; apical margin prominent, with dense and fine setae (not represented in fig. 32); apical 7/20 to 17/20 area with dense numerous microtrichia except longitudinal median area with setae of various lengths; apical half margin fringed with setae of various lengths. Sternite VIII (Fig. 33) coalesced tergite VIII at part of lateral margin; basal area membranous, with definite limit between sclerotized area; sclerotized area almost as long as wide, with setae longer and denser apicad; speculum elongate, attached to sclerotized area of sternite VIII (Fig. 34).
Genitalia. Ovipositor (Fig. 35) long; coxites (Figs. 36, 37) with indefinite limit of two segments in ventral view; each coxite with two setae in dorsal view, with three setae in ventral view, with a short seta at apex; stylus without distinct pubescence (probably lost due to bad condition); vagina long, with a two dome-shaped bulges; bursa copulatrix (Fig. 35) thick and long, without sclerotized piece; spermatheca (Fig. 35) attached to apex of bursa copulatrix, coiled.
Remarks. I determined a type specimen as the holotype because only one specimen was recorded in the original description and I could found one type specimen in the Fleutiaux collection of the Muséum National d’historie Naturelle, Paris.
This species exhibits sexual dimorphism regarding antennae. The male possesses long antennae extending to the apices of the pronotal posterior angles by the apical segments, whereas the female possesses short antennae that do not extend to the apices of pronotal posterior angles by the apical segments. I determined that the holotype is male by comparing the lengths of antennae of specimens examined, although the sex of the holotype was not assigned in the original description.
