Horaeomorphus sp.  Figs 1B, 6A, 6F

Material examined.

3 ♀♀, labeled 'China: Guangxi Prov., Shangsi County [上思县], Shiwandashan [十万大山], alt. 300-400m, 23.iv.2011, Peng, Zhai &Zhu leg.'.

Description.

Body (Fig. 1B) large, strongly convex, BL 2.48-2.51 mm; HL 0.37-0.38 mm; HW 0.50 mm; antennae (Fig. 6A) relatively short, AnL 0.99 mm; relative lengths of antennomeres: 1.0 : 0.8 : 1.2 : 1.0 : 1.0 : 0.9 : 0.9 : 0.9 : 1.0 : 1.0 : 2.2; PL 0.74-0.76 mm; PWm 0.59-0.61 mm; PWb 0.46-0.47 mm; EL 1.35-1.39 mm; EW 1.00-1.03 mm; EI 1.30-1.38.

Spermatheca (Fig. 6F) elongate, SpL 0.13mm; with longitudinal groove at middle.

Comments.

These females have strongly convex and broadened elytra (EI 1.30-1.38), distance between humeral calli wider than the width of the pronotum at base, large and deep punctures sharply delimited from background in the center of pronotal disc and anterior third of elytra. The shape of the spermatheca is similar to that of Horaeomorphus caverniventris  Jałoszyński, 2006 (Malaysia: Pahang), but females of the Malaysian species are larger (2.79-3.12 mm). Therefore the three specimens almost certainly belong to a new species, but a male must be found for formal description.

Distribution.

Southern China: Guangxi.
