Diagnosis
Reddish brown; length 2.80–2.95; postgenae rounded; antennomeres IX–XI enlarged, IX modified in the male; pronotum with lateral margins roundly expanded basolaterally; with short blunt metaventral processes; metacoxae spinose; aedeagus with asymmetric median lobe.
Description
Male (Fig. 6D). Length 2.80–2.95. Head longer than wide, HL 0.65–0.66, HW 0.59–0.60; eyes each composed of about 17 facets. Antennal clubs as in Fig. 10A. Pronotum (Fig. 10B) about as long as wide, PL 0.61–0.62, PW 0.59–0.60, with round lateral margins. Elytra wider than long, EL 0.71–0.74, EW 1.08–1.09. Short metaventral processes with rounded apices (Fig. 10C). Protrochanters and profemora simple (Fig. 10D), protibiae with distinct small apical tubercle (Fig. 10E); mesotrochanters (Fig. 10F) with blunt triangular spine at ventral margin; metacoxae (Fig. 10G) with hook-like protuberance at ventral margin, metatrochanters and metafemora simple. Abdomen broad at base and narrowed apically, AL 0.83–0.93, AW 1.14–1.19. Sternite IX as in Fig. 10H. Aedeagus length 0.60, with asymmetric median lobe (Figs 10I–K).
Female. Similar to male in general; BL 2.81–2.92, HL 0.64–0.66, HW 0.58–0.59, PL 0.60–0.62, PW 0.60–0.62, EL 0.70–0.72, EW 1.16–1.19, AL 0.87–0.92, AW 1.22–1.25. Eyes each composed of about 16 facets. Antennae lacking modification; metaventral processes absent.
Comparative notes
Linan tendothorax is placed as a member of the Labomimus cardialis species-group (sensu Yin et al. 2011b[1]) based on its strongly modified antennomeres IX–X. It can be separated from all known Linan species by the unique pronotum that is roundly expanded laterally at the basolateral margins.
Distribution
Southwest China: Yunnan.
Biology
Individuals were sifted from mixed litter, moss, debris and dead wood in primary or secondary deciduous forests.
Etymology
The species name is combined from the Latin stem ‘tend’ and Greek word ‘thorax’, referring to the unique basolaterally extended pronotum of the new species.
