Atomaria natmataunga nov.sp.

Type material: Holotype ♂: "Mya, Chin state, barkspray, Natmataung NP , 2960 m, wnw Kanpetlet, 6.6.201 0, leg. D. Zimmermann " [ NHMW] . Paratypes: 6 ex. with the same data as the holotype [ NHMW, cES].

Etymology: Named after Nat Ma Taung, the local name for Mount Victoria, the highest mountain into the Chin hills range in Myanmar (Chin state).

Description: Male, 1,4 mm, reddish-brow, elytra with a dark band, hind wings developed. Covered with pale decumbent hairs, pubescence coarse, beetle less shiny. Legs slender and pale. Antennae also pale and slender, club well separated but with segments 9, 10 and 11 relatively small. Segments 6 to 8 are globose, but segment 7 is larger than 6 and 8. Segment 1 slightly elongated and curved, longer and broader than segment 2. Segment 2 also elongated but smaller and shorter than segment 1. Segment 9 and 10 not transverse. Pronotum somewhat broader than long, broadest at the base. Base fully depressed, margins slightly rounded, nearly straight. Puncture moderately strong and dense. Elytra also with puncture moderately strong and dense, somewhat more as on pronotum. Elytra in the middle with a dark band, more ore less distinct, widened to the margins.

Comment: Atomaria natmataunga nov.sp. ( fig. 1 ) is well separated from all known species by the combination of general shape, antennae and coloration. The aeodeagus is typically for the genus. The tip of the medianlobus is very acute.

Distribution: Known only from the Nat Ma Taung National Park (Chin hills range in Myanmar).
