Genus: Pselaphodes
Name
Pselaphodes longilobus Yin & Hlaváč sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
(4 ♂♂, 5 ♀♀). Holotype: ♂, labeled ‘P. R. CHINA, Yunnan / Jizushan, 25°58'39"N, 100°21'14E / 28.VI.2011, 3216 m / sift27, V. Grebennikov’ (pcPH); Paratypes: 1 ♂, 4 ♀♀, same label data as holotype, except ‘25°58'18"N, 100°21'33N / 30.VI.2011, 2875 m / sift30’ (pcPH, SNUC); 2 ♂♂, 1 ♀, labeled ‘P. R. China, Hubei / Dabieshan, 31°06.013'N, 115°47.300'E / 11–21.VI.2008, 640 m / sifting, V. Grebennikov’ (pcPH, SNUC).
Diagnosis
Reddish brown; length 3.31–3.37; 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. 13B). Length 3.31–3.37. Head longer than wide, HL 0.71–0.73, HW 0.63–0.64; eyes each composed of about 25 facets. Antennal clubs as in Fig. 15A. Pronotum (Fig. 15B) slightly longer than wide, PL 0.69–0.71, PW 0.61–0.66, rounded at anterolateral margins. Elytra wider than long, EL 0.87–0.88, EW 1.23–1.29. Metaventral processes broad and long, apically narrowed (Fig. 15C). Protrochanters and profemora spinose ventrally (Fig. 15D), protibiae with tiny apical projection (Fig. 15E); mesotrochanters with two ventral spines, mesofemora simple (Fig. 15F); metatrochanters and metafemora simple (Fig. 15G). Abdomen broad at base and narrowed apically, AL 1.04–1.05, AW 1.28–1.30. Sternite IX as in Fig. 15H. Aedeagus length 0.70, with asymmetric median lobe (Figs 15I–K).
Female. Similar to male in general; BL 3.36, HL 0.74, HW 0.61, PL 0.70, PW 0.65, EL 0.85, EW 1.29, AL 1.07, AW 1.38. Eyes each composed of about 20 facets. Antennae unmodified; metaventral processes absent.
Comparative notes
This new species can be separated from the other species of the group by the metaventral processes being curved from the mid-length and then narrowed apically, the aedeagus with an elongate and apically truncate median lobe, the structure of the aedeagal endophallus, and its distribution.
Distribution
Southwest China: Yunnan; Central China: Hubei.
Biology
Individuals were sifted from leaf litter in forests.
Etymology
The specific name refers to the long aedeagal median lobe of the new species.
