==Type material==
(5 ♂♂, 5 ♀♀)'''.''' Holotype: ♂, labeled ‘'''CHINA:''' Zhejiang Prov. / Qingyuan County / Baishanzu N. R. / [http://ptp.pensoft.eu/redirect_to_googlemap.php?labels%5B0%5D=27%C2%B045%27N%2C+119%C2%B013%27E&coordinates%5B0%5D=27%C2%B045%27N%2C+119%C2%B013%27E 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 ‘[http://ptp.pensoft.eu/redirect_to_googlemap.php?labels%5B0%5D=27%C2%B044%27N%2C+119%C2%B013%27E&coordinates%5B0%5D=27%C2%B044%27N%2C+119%C2%B013%27E 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.<br />
Habitus as in Fig. 1B. General appearance similar to that of ''{{Taxon name|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.<br />
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.<br />
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 ''{{Taxon name|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.
