Taxonomy. The genus Vombisidris is assigned to the Romblonella genus group of the tribe Formicoxenini (Bolton 2003). The worker of the single Vietnamese species has the following features.
Worker monomorphic; head in full-face view subrectangular, with round posterolateral corners; frontal carina and antennal scrobe absent; median portion of clypeus roundly convex anteriad; median clypeal seta absent; posterior portion of clypeus broadly inserted between frontal lobes; mandible triangular; masticatory margin with 5 teeth; large apical tooth followed by two smaller teeth, then a long diastema (or very finely serrate margin) and two small basal teeth; antenna 12-segmented, with strongly defined 3-segmented club; eye well developed; sides of head below eye with a strong, sinuate, subocular groove; mesosoma in lateral view elongate and low; promesonotum not convex dorsad; promesonotal suture and metanotal groove absent dorsally; propodeal spine developed well; propodeal lobe roundly expanded; petiole pedunculate, with relatively low node, with a subpetiolar process on anteroventral face of peduncle; gastral shoulder weakly present; sting well developed and simple.
The worker of Vombisidris is somewhat similar to that of Temnothorax , but in the latter the side of head below the eye lacks a subocular groove.
Vietnamese species. Only one species has been found from Vietnam: sp. eg-1 (Cuc Phuong).
Bionomics. A single colony was found inside a shoot of Saraca dives Pierre (Leguminosae) (Eguchi & Bui, 2007).
Vombisidris is a genus of subarboreal and arboreal ants in the subfamily Myrmicinae.[2] Its species are known from India to Queensland, Australia. Like most other arboreal ants, their biology remains unknown.[3]
