Laena rolandi n. sp. ( Figs 10 , 24 )

Holotype (♂): N Thailand, Chiang Mai, Doi Pui, 1600–1685 m, 7.–9.V.2004, leg. R. Grimm, CRGT.

Paratypes: N Thailand, Chiang Mai, Doi Suthep Pui NP, 30.V.1999, leg. R. Grimm, 1 ex. CRGT. – N Thailand, Chiang Mai, Doi Pui, 1600–1685 m, 23.IV.–12.V.2003, leg. R. Grimm, 5 ex. CRGT, 2 ex. SMNS.

Etymology: Dedicated to Dr. Roland Grimm (Tübingen), collector of the type series, for fruitful long­term cooperation.

Diagnosis: Laena rolandi n. sp. and Laena thailandica Kaszab & Chûjô, 1966 (see photo 6 in Kaszab & Chûjô 1966) from southern Thailand share the small body size, unarmed legs and the glabrous surface, but can be separated by completely different shaped pronotum (round and widest in the middle in thailandica ), dense nearly confluent pronotal punctation (sparse in thailandica ), unbordered lateral pronotal margin (bordered in thailandica ) and narrower elytral intervals. The aedeagus of Laena thailandica is unknown and so can not be compared.

Description: Body length 3.8–5.0 mm. Eyes somewhat prominent. Pronotum ( Fig. 10 ) with large punctures, distance between 0.5–3 diameters, most punctures bearing short adpressed seta; surface flat, shining; lateral margin unbordered; propleura with sparser punctation, nearly without setation. Elytra ( Fig. 10 ) with complete rows of punctures without striae, punctures equal in size to pronotal punctures, all without setae; intervals with very few scattered punctures, without setae, 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. 24 .
