Laena kurbatovi n. sp. ( Fig. 8 )

Holotype (Ψ): N Burma, Chin Prov., Saw, 900–1500 m, 27.–28.II.1996, leg. S. Kurbatov, HNHM.

Etymology: Dedicated to Sergej A. Kurbatov (Moscow), collector of the holotype.

Diagnosis: Separated from the single known species from Burma ( Laena bicolor Schuster, 1926 ) by the smaller body size (5.0 mm in Laena bicolor ), lack of prominent eyes (prominent in Laena bicolor ), distinctly bordered lateral margin of the pronotum (unbordered in Laena bicolor ), the distinct row of punctures on the elytral intervals (smooth in Laena bicolor ), and several setiferous pores on elytral interval 9 (a single tooth­like setiferous pore on interval 9 in bicolor ). Because of these distinct differences, I decided to describe this species from a quite remote area as new even without having a male available (the aedeagus of Laena bicolor thus unknown). Laena kurbatovi n. sp. is quite similar to Laena vietnamica Masumoto, 1995 from northern Vietnam and Laena champasaka n. sp. from southern Laos, but can be separated by differently shaped pronotum and different dorsal punctation and setation (compare Figs 1, 8 , 15 ). See also under Laena khaolaka n. sp. from southern Thailand with slightly armed femora ( Fig. 6 ).

Description: Body length 3.7 mm. Eyes not prominent. Pronotum ( Fig. 8 ) with large punctures, distance between 1–4 diameters, most punctures bearing long erect seta; surface flat, shining; lateral margin distinctly bordered, somewhat crenulate; propleura with similar punctation, setation to disc. Elytra ( Fig. 8 ) with complete rows of punctures without striae, punctures equal in size to pronotal punctures most bearing long, erect seta; intervals with a row of distinct punctures each bearing erect seta of similar length, anterior of interval 9 with several setiferous pores so that the shoulder looks dentate; all intervals distinctly convex, shining. Femora without distinct tooth or other modification. Sexual dimorphism unknown. Aedeagus unknown, only female available.
