Diagnosis of male. Length over 3.50 mm; antennomeres IX–XI elongate, IX strongly expanded, with large disc-like structure near apex; antennomere X transverse; metaventral processes moderately elongate; protrochanter with acute ventral spine, profemur with large, broad ventral spine, protibia with blunt apical projection; mesotrochanter with tiny ventral spine, mesotibia with small apical spine; aedeagus asymmetric, with median lobe narrow and curved leftwards at apex.
Description. Male ( Fig. 4A View FIGURE 4 ). Length 3.66 mm. Head longer than wide, HL 0.76 mm, HW 0.67 mm; eyes prominent, each composed of about 40 facets. Antenna with scape about 2.9 times as long as wide, antennomeres II–VII more or less elongate; antennomere VIII transverse, antennomere IX ( Fig. 5A View FIGURE 5 ) strongly expanded, with large disc-like structure near apex, antennomere X subquadrate, strongly transverse. Pronotum ( Fig. 5B View FIGURE 5 ) slightly longer than wide, PL 0.71 mm, PW 0.68 mm, sides roundly angulate at apical two-fifths. Elytra much broader than long, EL 0.85 mm, EW 1.31 mm. Metaventral processes ( Fig. 5C View FIGURE 5 ) moderately elongate, narrowed apically in lateral view. Protrochanter ( Fig. 5D View FIGURE 5 ) with distinct ventral spine, profemur with large, triangular ventral spine at middle, protibia ( Fig. 5E View FIGURE 5 ) with small, blunt projection at apex; mesotrochanter ( Fig. 5F View FIGURE 5 ) with small spine at ventral margin, mesofemur strongly expanded, mesotibia ( Fig. 5G View FIGURE 5 ) with small spine at apex; metacoxa, metatrochanter, and metafemur ( Fig. 5H View FIGURE 5 ) simple. Abdomen broad at base and narrowed posteriorly, AL 1.34 mm, AW 1.35 mm; tergite IV longest, more than twice as long as tergite V; sternite IX as in Fig. 5I View FIGURE 5 . Length of aedeagus ( Fig. 5 View FIGURE 5 J–L) 0.53 mm; median lobe slightly asymmetric, slight curved leftward and pointed at apex; parameres broad, curved in lateral view, each with two long apical macrosetae.
Female. Unknown.
Distribution. China: Yunnan.
Etymology. The specific epithet refers to the stout body form of the new species.
Comparative notes. The new species is similar to L. torus Yin, Li & Zhao from Qinghai and L. paratorus Yin & Li, 2012 from Shaanxi in sharing a stout habitus and an enlarged antennomere IX in the male. Labomimus corpulentus sp. nov. can be readily separated from both latter species by the small apical spine or projection of the pro- and mesotibia, and the much borderer median lobe of the aedeagus in dorso-ventral view.
