Genus: Pselaphodes
Name
Pselaphodes wrasei Yin & Li sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
(1 ♂, 5 ♀♀). Holotype: ♂, labeled ‘CHINA (N-Yunnan) Zhongdian Co. / 36 km ESE Zhongdian, 3500–3550 m / 27°40'09"N, 100°01'05E (over grown / rock hillside with old mixed forest, / bamboo, dead wood, leaf litter) / 23–24.VIII.2003 Wrase [13]’ (pcMS); 4 ♀♀, same label data as holotype (pcMS); 1 ♀, same label data, except ’24.VIII.2003, M. Schülke’ (pcMS).
Diagnosis
Reddish brown; length 3.27–3.32; postgenae rounded laterally; antennomeres IX–XI enlarged; antennomeres IX modified in male; pronotum rounded at anterolateral margins; male with long metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.
Description
Male (Fig. 19A). Length 3.32. Head longer than wide, HL 0.75, HW 0.68; eyes each composed of about 45 facets. Antennal clubs as in Fig. 20A. Pronotum (Fig. 20B) slightly longer than wide, PL 0.72, PW 0.69, rounded at anterolateral margins. Elytra wider than long, EL 0.89, EW 1.34. Metaventral processes long, apically narrowed (Fig. 20C). Protrochanters and profemora spinose ventrally (Fig. 20D), protibiae with small apical projection (Fig. 20E); mesotrochanters with single ventral spine, mesofemora simple (Fig. 20F); metatrochanters and metafemora simple (Fig. 20G). Abdomen broad at base and narrowed apically, AL 0.96, AW 1.41. Sternite IX as in Fig. 20H. Aedeagus length 0.62, with asymmetric median lobe (Figs 20I–K).
Female. Similar to male in general; BL 3.27–3.32, HL 0.73–0.74, HW 0.62–0.63, PL 0.68–0.70, PW 0.65–0.66, EL 0.81–0.82, EW 1.29–1.31, AL 1.05–1.06, AW 1.45–1.46. Eyes each composed of about 25 facets. Antennae unmodified; metaventral processes absent.
Comparative notes
This species can be separated from the other species of the group by the thin, elongate metaventral processes, the thin median lobe of the aedeagus, the structure of the aedeagal endophallus, and its distribution.
Distribution
Southwest China: Yunnan.
Biology
Adults were collected by sifting leaf litter and moss in mixed forests.
Etymology
The new species is named after David W. Wrase, collector of the holotype and most paratypes.
