Laena inthanonica n. sp. (Figs 3, 17)

Holotype (♂): N Thailand, Doi Inthanon, 2500 m, 9.II.1986, leg. P. Schwendinger, MHNG.

Etymology: Named after the isolated Doi Inthanon mountain range where this species and other congeners were collected.

Diagnosis: Can be recognized by body shape and size, unbordered lateral margin of the pronotum and nearly glabrous dorsal side. Laena schwendingeri Schawaller, 1998 from the same region is quite similar, however, in this species, the body size averages somewhat smaller (4.3–6.0 mm), the shape of the pronotum is rounder, widest in the middle, most punctures of the elytral rows bear a long, erect seta, and the aedeagus is different (compare Figs 19–21 in Schawaller 1998).

Description: Body length 6.5 mm. Eyes distinctly prominent. Pronotum (Fig. 3) with large punctures, distance between 1–5 diameters, most punctures bearing long erect seta; surface flat, shining; lateral margin unbordered; propleura with sparser punctation, shorter setation. Elytra (Fig. 3) with complete rows of punctures without striae, punctures equal in size to pornotal punctures, punctures with indistinct microseta not longer than diameter of puncture; intervals with very few scattered punctures each bearing long erect seta, interval 9 with 3 distinct setiferous pores; all intervals slightly convex, shining. Femora in both sexes without distinct tooth or other modification. Tibiae in males without distinct sexual character. Aedeagus see Fig. 17.
