Vombisidris BoltonHNS, 1991

Taxonomy. The genus VombisidrisHNS is assigned to the RomblonellaHNS genus group of the tribe FormicoxeniniHNS (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 VombisidrisHNS is somewhat similar to that of TemnothoraxHNS, 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).
