Laena khaolaka n. sp. (Figs 6, 20)

Holotype (♂): S Thailand, Khao Lak NP, Thone Chong Fa Fall, 100–300 m, 6.–15.I.1998, leg. A. Schulz & K. Vock, SMNS.

Paratypes: Same data as holotype, 18 ex. SMNS, 3 ex. CRGT, 3 ex. HNHM, 3 ex. MHNG, 3 ex. NSMT.

Etymology: Named after the Khao Lak National Park, where the types were collected.

Diagnosis: Laena khaolaka n. sp. and Laena siamica Kaszab, 1973 also from southern Thailand share similar dorsal punctation, setation, but can be separated by the differently shaped pronotum (Figs 6, 11), feeble angle on the femora (with distinct tooth in Laena siamica), and differently shaped aedeagus (longer joint parameres in Laena siamica, see Fig. 18 in Kaszab 1973). Laena khaolaka n. sp. is also similar to Laena kurbatovi n. sp. from northern Burma, but can be separated by the armed femora (completely unarmed in Laena kurbatovi n. sp.) and the 2 distinct setiferous pores on the elytral interval 9 (several pores on interval 9 so that the shoulders appear dentate in Laena kurbatovi n. sp.).

Description: Body length 3.5–6.0 mm. Eyes not prominent. Pronotum (Fig. 6) with large punctures, distance between 0.5–3 diameters, most punctures bearing long erect seta; surface flat, shining; lateral margin bordered, somewhat crenulate; propleura with similar punctation, setation to disc. Elytra (Fig. 6) with complete rows of punctures without striae, punctures equal in size to pronotal punctures, most bearing long, erect seta; intervals with row of distinct punctures each bearing erect seta of similar length, interval 9 with 2 distinct setiferous pores; all intervals distinctly convex, shining. Femora in both sexes with a feeble angle. Tibiae in males without distinct sexual character. Aedeagus see Fig. 20.
