Ordo: Coleoptera
Familia: Staphylinidae
Genus: Lathrobium
Name
Lathrobium manissimum Peng & Li sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
(5 ♂♂, 5 ♀♀). Holotype: ♂, labeled ‘CHINA: Zhejiang Prov. / Qingyuan County / Baishanzu N. R. / 27°45'N, 119°13'E / 22–23.ix.2008, alt. 1,500 m / Tang & Zhang leg.’. Paratypes: 3 ♂♂, 4 ♀♀, same label data as holotype; 1 ♂, 1 ♀, same label data, but ‘27°44'N, 119°13'E / 21.viii.2004, alt. 1,250–1,650 m / Hu, Tang & Zhu leg.’.
Description
Measurements and ratios:BL 10.57–12.51, FL 5.33–6.17, HL 1.63–1.70, HW 1.88–1.95, PL 2.23–2.30, PW 1.95–2.07, EL 1.40–1.50, HL/HW 0.86–0.88, HW/PW 0.94–0.96, HL/PL 0.73–0.74, PL/PW 1.11–1.14, EL/PL 0.63–0.65.
Habitus as in Fig. 1B. General appearance similar to that of Lathrobium baishanzuense, except for the much broader and larger body, the narrow impunctate midline on the pronotum and coarser punctation on the head, pronotum and elytra.
Male. Sternite III (Fig. 4H) with dense dark setae in small posterior impression; sternite IV (Fig. 4I) with dense darkish setae in postero-median impression and posterior margin with several peg-like setae; sternite V (Fig. 4K) similar to sternite IV, but with sparser setae in larger impression; sternite VI (Fig. 4J) with long setae in postero-median impression and posterior margin with several peg-like setae; sternite VII (Fig. 4D) with sparse setae in postero-median impression; sternite VIII (Fig. 4G) with shallow symmetric emargination and short dark setae in large impression; sternite IX (Fig. 4C) asymmetric; aedeagus (Fig. 4F, 4L) with very long ventral process curved to the left in ventral view, broad dorsal plate and with single sclerotized apical spine in internal sac.
Female. Posterior margin of tergite VIII (Fig. 4A) truncate; sternite VIII (Fig. 4B) longer than that of male, posterior margin strongly convex; tergite X (Fig. 4E) obtuse apically and almost reaching anterior margin of tergite IX (Fig. 4E).
Distribution
East China: Donggong mountain range.
Etymology
The specific epithet (superlative of the Latin adjective immanis: huge) alludes to the size of the aedeagus.
Comparative notes
. The new species is readily distinguished from all eastern Chinese Lathrobium species by the large size and stout habitus, and by the presence of dense dark setae in the small posterior impression of sternite III.
