Type material
(2 exs). Holotype: CHINA: ♂, labeled 'China: Sichuan, Chengdu City (成都市), Dujiangyan City (都江堰市), Zipingpu Township (紫坪铺镇), Ling-yan-guan-yin-shan (灵岩观音山), 31.03°N, 103.61°E, 1180 m, 03.iv.2017, ant nest under rock, Zhou Chao & He Li leg.' (SNUC). Paratypes: CHINA: 1 ♂, same collecting data as the holotype, except 'ant colony under bark,' (SNUC).
Diagnosis.
Batrisodes zhouchaoi can be readily separated from all other Chinese congeners by the following combination of characters: antennomere X strongly transverse, with a small denticle at mesal margin, XI with a small denticle base; pronotum distinctly winder than long; mesotrochanter with a blunt ventral projection, mesofem ora with a long ventral protuberance at middle, mesotrochanter protuberant ventrally, metafemora expanded along the ventral margin; aedeagus strongly asymmetrical, with elongate, twisted ventral and dorsal lobes.
Description.
Male. (Fig. 11A), Body reddish brown, BL 2.18-2.19 mm. Head wider than long, near rectangular, and covered with short hair HL 0.45-0.46 mm, HW 0.50-0.51 mm, with large vertexal foveae, antennal tubercles prominent and punctate; area between obviously raised antennal tubercles concave and sparsely pubescent; clypeus slightly punctate, with round anterior margin; lateral longitudinal carinae extending from above eyes to occipital constriction. Each eye composed of about 55 facets. Antennomeres II–IX moniliform, X (Fig. 11B) much wider than long with small denticle near middle, XI (Fig. 11B) largest and with small denticle near base. Pronotum wider than long, PL 0.48-0.50 mm, PW 0.55- 0.56 mm, disc slightly convex; with small antebasal foveae, median and lateral longitudinal sulci clear; lateral antebasal fovea large and distinct, outer and inner basolateral foveae distinct. Elytra slight wider than long, EL 0.74-0.75 mm, EW 0.77-0.78 mm; each elytron with three large basal foveae, discal striae shallow and short. Mesotrochanter (Fig. 11C) with blunt, short spine; mesofemora (Fig. 11C) expanded at apical 1/3 and with long and distinct ventral spine at middle; mesotibiae (Fig. 11D) with distinct ventral denticle spine near middle and a small triangular apical denticle; metafemora (Fig. 11E) expanded along ventral margin, metatibiae (Fig. 11F) with long apical tuft of setae. Abdomen wider than long, AL 0.48-0.51 mm, AW 0.72-0.74 mm; tergite IV longest, three times as long as next, with distinct oblique marginal carinae. Aedeagus (Fig. 11 G–I) slender and asymmetrical, median lobe simple with two elongate and twisted lobe; length of aedeagus 0.48 mm.
