Abst ract The Vombisidris Bolton is recorded in China for the first time. A new species of the genus , V. umbrabdomina sp. nov. , is described. The new species is close to V. nahet Bolton but differs in sides of mesonotum slightly convex, not obtusely angular in dorsal view, antennal scape longer , colour yellowish2brown , gaster dark brown, darker than head and alitrunk.

The ant genus Vombisidris , described by Bolton Eyes at or slightly in front of the midlength of the sides in 1991 , is a small genus in the subfamil y of the head. Antennae 122segmented with a strongly , containing only 13 species in the world defined 32segmented club. Sides of head usuall y with a (Bolton , 1991 ; Zacharias, 2004 ) . Among the 13 strong sinuate subocular groove. Alitrunk elongate and known species , 2 are distributed in Pap ua New low in p rofile , promesonotum not domed2convex ; Guinea , 3 in East Malaysia , 3 in Indonesia, 2 in p ropodeum bispinose , p ropodeal spiracle high on side , Australia , 2 in India, and 1 in Bruner. This genus is at about midlength of sclerite, distinctl y separated predominantly arboreal and ranges from India to from the small metapleural gland bulla. Metapleural Queensland, with the majority of species in Malaysia lobes small and rounded. Petiole pedunculate. and Indonesia. A new species of the genus is described Postpetiolar sternite reduced, small in p rofile (Bolton , in this paper. The t ype specimen is deposited in the 1991) .

The large apical tooth followed by running from the mandibular insertion to the two smaller teeth (third smaller than second ) , then a anteroventral margin of the eye , then passing through long diastema and two small basal teeth. Len gth of a shallow angle and continuing along the sides to the diastema is at least equal to length of margin occupied lateroccipital margin, where the subocular groove ends by the apical group of three teeth. Anterior cl ypeal slightly concave. Antennal scape relatively long ( SI margin lacking an isolated median seta, instead with a 83) .Eyes relatively large ( 0128 × HW ) with 10 pair of setae that straddle the midpoint. Frontal lobes ommatidia in the longest row. Alitrunk elongate and narrow. Torulus concealed b y frontal lobes in full face low in profile, mesonotum unarmed. In dorsal view, view. Frontal carinae and antennal scrobes absent.
