Genus: Pselaphodes
Name
Pselaphodes pengi Yin & Li sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
(3 ♂♂). Holotype: ♂, labeled ‘CHINA: Sichuan, Tianquan County / Labahe N. R., Heixuan Valley, ca. 30 / km NW Tianquan, 30°10'36"N, 102°28'04E, 2000 m, (mixed leaf litter / sifted), 2012.vii.10, Dai, Peng, Yin’ (SNUC). Paratypes: 1 ♂, same label data as holotype (SNUC); 1 ♂, labeled ‘CHINA: Sichuan, E’meishan City / E’mei Shan Mt., pass between / Jiuling Hill and Xixinsuo Temple / 29°33'15"N, 103°21'24E, 1800 m / (leaf litter, sifted), 2012.vii.24 / C. C. Dai, Z. Peng & Z. W. Yin leg.’ (SNUC).
Diagnosis
Reddish brown; length 3.41–3.50; postgenae rounded laterally; antennomeres IX–XI enlarged; VI–VII and IX–XI modified in male; pronotum rounded at anterolateral margins; male with long metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.
Description
Male (Fig. 25B). Length 3.41–3.50. Head longer than wide, HL 0.76–0.78, HW 0.74–0.75; eyes each composed of about 50 facets. Antennal clubs as in Fig. 27A. Pronotum (Fig. 27B) slightly longer than wide, PL 0.78–0.79, PW 0.74–0.75, rounded at anterolateral margins. Elytra wider than long, EL 0.94–0.99, EW 1.32–1.35. Metaventral processes long, apically broadened (Fig. 27C). Protrochanters and profemora strongly spinose at ventral margins (Fig. 27D), protibiae with small apical spur (Fig. 27E); mesotrochanters with distinct ventral spines, mesofemora with small ventral spine (Fig. 27F); metatrochanters and metafemora simple (Fig. 27G). Abdomen broad at base and narrowed apically, AL 0.93–0.94, AW 1.31–1.37. Sternite IX as in Fig. 27H. Aedeagus length 0.60, with asymmetric median lobe (Figs 27I–K).
Female. Unknown.
Comparative notes
The new species has unique, modified antennomeres VI, combined with the slightly modified antennomeres VII, the enlarged antennomeres IX with a round apical process, the metaventral processes each with a preapical denticle on the upper surface, and the aedeagus with an apically greatly broadened median lobe, it can be quickly separated from all other species of the genus. Currently there is no other Pselaphodes species known to process modified antennomeres VI in the male.
Distribution
Southwest China: Sichuan.
Biology
Individuals were sifted from leaf litter along roads in forests.
Etymology
This species is named after Zhong Peng, co-collector of the type series.
