( Figs. 14 , 20 ) Holotype ( ♂ ): NW Thailand , W Pai , sifted above waterfall, 800 m , 19.IV.2004 , leg. W. Schawaller , SMNS . FIGURES 12–13. Dorsal view of Oriental species of Indenicmosoma . 12 I. magnum , non-type. Malaysia (Perak). SMNS. 13 I. pocsi , non-type. Thailand. SMNS. Scale line: 1 mm. Description: Body length 3.6 mm. Dorsal and ventral surfaces and all appendages dark yellow-brown, head somewhat darker; dorsal and ventral surfaces punctured, punctures with short adpressed microsetae, surface between punctures shining. Head with distinctly denser punctation than pronotum, but not confluent; genae somewhat swollen but not dilated, with weak transverse impression between genae; anterior margin of epistome straight and without excavation or other modifications; eyes round and prominent, not enchroached by genae; antennae with 10 antennomeres, shape of the antennomeres as in Fig. 14 , antennomere 3 distinctly longer than antennomere 2, terminal two antennomeres forming loose club, terminal antennomere feebly bipartite. Pronotum widest in anterior third, anterior and posterior margins unbordered, lateral margins unbordered but distinctly crenulate, anterior angles rounded, posterior corners rectangular; surface convex with punctation irregular, coarse but not confluent, punctures larger to those of head and similar to those of elytra, prothoracic hypomera with similar punctation as on pronotum. Prosternum not prominent. Hind wings completely developed. Metasternal punctures larger laterally than medially. Elytra parallel-ovate, widest behind middle, lateral margins completely visible in dorsal view, surface with irregular punctation not arranged in rows or striae, epipleura with similar punctation as on elytra. Abdominal ventrites with punctures larger laterally than medially, terminal ventrite unbordered. Legs without particular modifications. Aedeagus ( Fig. 20 ) with broad triangular apicale with rounded tip. Diagnosis: Indenicmosoma paicum sp. nov. can be recognised by the large body length above 3.0 mm in combination with a narrow high convex pronotum widest in anterior third and parallel-ovate elytra, and by the shape of the aedeagus. I. magnum has a similar large body size (3.2–3.3 mm), but the pronotum is distinctly wider and flat, and the elytra are shorter. The aedeagal apicale of I. paicum sp. nov. is longer than the apicale of I. magnum , compare Figs. 17, 20 . Etymology: Named after the village Pai, in whose vicinity the holotype was collected. Distribution: Known only from the type locality in northern Thailand .
