37) Eoxizicus (Eoxizicus) bihammeris Liu sp. n.

Holotype ♂ (left middle and hind legs, right middle and front legs lost): Laos: Bolouens / Plateau, 16km S of/ Thateng, 1020 m / 22–24.VII.1960; R. E. Leech / Collector / BISHOP; Malaise Trap

Paratype 1♀ (left front and hind legs, right hind leg lost): labeled as Holotype without third lable

Description. General appearance typical of the genus. Body moderate size. Fastigium of vertex with conical apex. Pronotum with relatively deep lateral plate, humeral sinus more or less distinct. Tegmina and wing well developed, moderately long. Hind tibia with 3 pairs of apical spurs.

Male 10 th tergite extended into a pair of posteriormedian processes separated each other, apex enlarged into 2 hammer-like lobes, bend slightly downwards (Fig. 17a). Male cerci with basal half widened into broad lobe, apical half narrowed lobe and bend inward in right angle. Subgenital plate with roundly even posterior margin, styli short (Fig. 17 a–c).

Female subgenital plate short with round posterior margin and a median furrow (Fig. 17d, e). Ovipositor almost straight with smooth and acute apex.

Measurement (mm). Body: ♂ 11.0, ♀ 11.1; Pronotum: ♂ 4.2, ♀ 4.1; Tegmina: ♂ 17.8, ♀ 18.6; Hind femora: ♂ 10.3; Ovipositor: 8.9.

Comparison. Similar to Eoxizicus divergentis Liu & Zhang, 2000 from Guangxi, China, by paired median process of male 10 th tergite, but apical part enlarged. Also similar to Xizicus (Eoxizicus) khaosoki Gorochov, 1998 (Figs. 60, 61) from Thailand by shape of female subgenital plate, but with slight projected posteriomedian margin.

Etymology. Name refers to the shape of paired median process of male 10 th tergite in hammer-like form.
