Type material
(5 exs). Holotype: CHINA: ♂, labeled 'China: Guangxi, Jinxiu County (金秀县), Dayao Mountain (大瑶山), 16 km (十六公里), 24°08'11"N, 110°14'28"E, beech forest, rotten wood, colony of ant, 1100 m, 17.vii.2014, Zhong Peng leg.' (SNUC). Paratypes: CHINA: 4 ♀♀, same label data as the holotype (SNUC).
Diagnosis of male.
The new species can be separated from other Chinese Batrisodes species by the following combination of characters: head dorsum, pronotum, and elytra roughly punctate, antennomeres III–V wider than VI–X, mesotrochanter, mesofemur, and mesotibia spinose, and slightly asymmetrical aedeagus expanded at the apex.
Description.
Male. (Fig. 2A), Body reddish brown, BL 2.58 mm. Head approximately as long as wide, near trapezoidal, rough and covered with short hair, HL 0.46 mm, HW 0.50 mm, with large vertexal foveae, antennal tubercles prominent; area between moderately raised antennal tubercles concave; clypeus punctate, with round anterior margin; lateral longitudinal carinae slight, extending from level of eyes to head base, lacking median vertexal carina. Each eye composed of about 50 facets. Antennomeres II–X (Fig. 3A) moniliform, III–V slightly expanded, XI largest, nearly 2.5 times as long as X. Punctate pronotum slightly wider than long, PL 0.52 mm, PW 0.59 mm, disc slightly convex; with small median antebasal foveae, median and lateral longitudinal sulci distinct; lateral antebasal fovea large and distinct; outer and inner basolateral foveae small but distinct. Elytra as wide as long, with large uniform punctation and covered with long moderate-length hair, EL 0.87 mm, EW 0.87 mm; each elytron with three small but distinct basal foveae, discal striae shallow and unobvious. Mesotrochanter (Fig. 3B) with distinct triangular short spine; mesofemora (Fig. 3B) with thin but distinct ventral spine at middle; mesotibiae (Fig. 3C) with small ventral denticle near middle and an acute triangular apical spine. Abdomen wider than long, AL 0.73 mm, AW 0.85 mm; tergite IV longest, approximately 1.5 times as long as next, with strongly oblique marginal carinae. Length of aedeagus (Fig. 3 D–E) 0.35 mm; median lobe simple, flattened, apical obviously expanded, nearly symmetrical.
Female (Fig. 2B). Similar to male, antennomere III–V normal; each eye composed of about 40 facets; legs lacking denticle and spine; tergite VIII (Fig. 3F) semicircular; sternite VIII (Fig. 3G) transverse; symmetrical genital complex (Fig. 3H) slightly sclerotized. Measurements of body parts: BL 2.45-2.53 mm, HL 0.45-0.46 mm, HW 0.50-0.51 mm, PL 0.49-0.52 mm, PW 0.58-0.60 mm, EL 0.81-0.84 mm, EW 0.87-0.88 mm, AL 0.70-0.71 mm, AW 0.83-0.84 mm.
Distribution.
Southwestern China: Yunnan.
Host ant.
Odontomachus sp.
Biology.
All adults were collected from an Odontomachus colony in a tree hole (Fig. 12).
Etymology.
The specific epithet refers to the roughly punctate body surface of the new species.
