Pselaphodes maolanensis sp. nov.

( Figs 10A , 11 )

Type material ( 1 ex.). HOLOTYPE: ♁, CHINA: ‘ China: Guizhou, Libo Hsien ( ĠǾR), Maolan N. R. (ṈỄḄỸāŊḨOiṖữ), 25°13′00″N, 107°54′43″E, mixed leaf litter, sifted, 750–800 m, 21.vii.2015, He, Hu & Wang leg.’ ( SNUC).

Diagnosis of male. Length 2.64 mm; antennomere X slightly oblique at apex; metaventral processes broad; protibia with acute apical spine; aedeagus with broad, slightly asymmetric median lobe, parameres slender, nearly symmetric.

Description. Male ( Fig. 10A ). Body reddish brown, BL 2.64 mm. Head wider than long, HL 0.53 mm, HW 0.56 mm; each eye composed of about 35 facets.Antennomeres IX–XI ( Fig. 11A ) forming distinct club, antennomere X slightly oblique at apex. Pronotum ( Fig. 11B ) as long as wide, PL 0.55 mm, PW 0.55 mm, with lateral margins narrowing toward anteriorly at apical third. Elytra wider than long, EL 0.81 mm, EW 1.07 mm. Metaventral processes ( Fig. 11C ) broad and straight. Protrochanter ( Fig. 11D ) with triangular ventral spine; protibia ( Fig. 11E ) with large apical spine; middle and hind legs simple ( Figs 11 F–G). Abdomen broad at base and narrowed apically, AL 0.75 mm, AW 1.11 mm. Sternite IX ( Fig. 11H ) semi-membranous. Length of aedeagus ( Figs 11 I–K) 0.51 mm; median lobe broad and nearly symmetric, parameres elongate and slender, almost symmetric, endophallus composed of two elongate sclerites.

Female. Unknown.

Comparative notes. Males of the new species can be readily separated from all known congeners primarily by the stout general habitus, nearly unmodified antennal clubs, and unique form of the aedeagus.

Etymology. The specific name is derived from the type locality, i.e., Maolan National Nature Reserve; adjective.

Distribution. China: Guizhou.
