Diagnosis
Reddish brown; length 3.36–3.75; postgenae rounded; antennomeres IX–XI enlarged, IX–X modified in the male; pronotum with lateral margins moderately angulate laterally; with short sharp metaventral processes; metacoxae simple; aedeagus with median lobe nearly symmetric.
Description
Male (Fig. 1C). Length 3.41–3.75. Head slightly longer than wide, HL 0.71–0.72, HW 0.65–0.68; eyes each composed of about 45 facets. Antennal clubs as in Fig. 4A. Pronotum (Fig. 4B) about as long as wide, PL 0.70–0.73, PW 0.65–0.71, with roundly angulate lateral margins. Elytra wider than long, EL 0.87–0.93, EW 1.38–1.40. Metaventral processes short, narrowed from base toward apex (Fig. 4C). Protrochanters with small ventral spine, profemora with large thick ventral spine (Fig. 4D); mesotrochanters (Fig. 4E) with small spine at ventral margin, mesotibiae (Fig. 4F) with short blunt apical tubercle; metatrochanters and metafemora (Fig. 4G) simple. Abdomen broad at base and narrowed apically, AL 1.13–1.37, AW 1.35–1.43. Sternite IX as in Fig. 4H. Aedeagus length 0.67, with broad median lobe elongate nearly symmetric (Figs 3I–K).
Female. Similar to male in general; BL 3.36, HL 0.71, HW 0.64, PL 0.66, PW 0.64, EL 0.74, EW 1.21, AL 1.25, 1.43. Eyes each composed of about 35 facets. Antennae lacking modification; metaventral processes absent.
Comparative notes
The postgenae of the head being rounded and not laterally expanded quickly separates this species from Labomimus sichuanicus Hlaváč, Labomimus schuelkei sp. n. described below, Labomimus dabashanus and Labomimus shibatai. From the rest of the members of the genus, Labomimus mirus can be readily recognized by its characteristic antennal modification and aedeagus.
Distribution
Southwest China: Yunnan.
Biology
Species were sifted from various kinds of leaf litter and moss in mixed forests.
Etymology
Tha Latin word ‘mirus’ means ‘extraodinary, remarkable’, referring to the unique antennal modification and aedeagal form of this species.
