Type locality.

Jiulongshan Natural Reserve, Zhejiang Province, East China

Type material

(7 ♂♂, 5 ♀♀). Holotype: ♂, labeled 'CHINA: Zhejiang Prov. / Suichang County / Jiulongshan N. R. / 28.vii.2006, alt. 500-600 m / Li & Shen leg.'. Paratypes: 2 ♂♂, 3 ♀♀, same label data as holotype; 4 ♂♂, 2 ♀♀, same data, except 'Zhuji City / Majian Town / 16.x.2011, alt. 200 m / Tie-Xiong Zhao leg.'.

Description.

Measurements and ratios:BL 9.90-11.12, HL 1.36-1.43, HW 1.49-1.58, PL 1.74-1.80, PW 1.56-1.61, EL 1.05-1.14, HW/HL 1.07-1.14, HW/PW 0.94-0.98, HL/PL 0.76-0.80, PL/PW 1.12-1.13, EL/PL 0.59-0.65.

Habitus as in Fig. 1C. Generally similar to Lathrobium jiulongshanense , except for the lighter coloration of the legs, the somewhat larger body size, and the moderately sparse punctation on head and pronotum.

Male. Sternite V (Fig. 4C) with dense short darkish setae in posterior concavity; sternite VI (Fig. 4D) similar to sternite V, but with slightly shorter setae in median concavity; sternite VII (Fig. 4G) with different length of setae surrounding the distinctly asymmetric emargination in posterior portion; sternite VIII (Fig. 4F) with different length of setae in large impression and shallow posterior emargination; sternite IX (Fig. 4H) almost asymmetric; aedeagus (Fig. 4I, 4J) with short ventral process and dorsal sclerite.

Female. Posterior margin of tergite VIII (Fig. 4A) slightly convex; sternite VIII (Fig. 4B) longer than that of male, posterior margin distinctly pointed in the middle; tergite IX (Fig. 4C) narrowly separated from X (Fig. 4C) and with moderately slender lateral processes.

Distribution.

East China (Zhejiang: Jiulongshan Natural Reserve and Majian Town).

Etymology.

The species is named after Tie-Xiong Zhao, collector of the type series, a 12-year-old boy who is most enthusiastic about collecting beetles.

Remarks.

From other Lathrobium species of the Jiulongshan N. R., Lathrobium zhaotiexiongi is readily separated by the male sternite VII having setae of variable length surrounding the posterior emargination and the male sternite VIII having setae of variable length in the postero-median impression.
