Based on Ward et al. (2014) and Blaimer et al. (2018).

Vollenhovia species usually inhabit forest habitats and nest in rotting twigs, wood fragments and logs, and in spaces under the bark of logs. (Eguchi, Bui and Yamane 2011)

Identification

Similar to Gauromyrmex but differing by the 12-segmented antennae and the unarmed propodeum.

Terayama and Kinomura (1997) - This genus is distinguished from the other genera of the subfamily Myrmicinae by the following characteristics: 1) frontal carinae and antennal scrobes absent; 2) clypeus more or less longitudinally bicarinate; 3) antennae with 12 segments, rarely 11 segments. the funicles ending in a 3-segmented club; 4) frontal lobes present; 5) maxillary palp with 1-3 segments. usually 2 segments; 6) eyes present, relatively large; 7) ventral processes distinct on meso-and metasternum; 8) middle and hind legs without tibial spur; 9) petiole sessile or subsessile; 10) subpetiolar process present, often blade-like; 11) petiole not particularly more voluminous than postpetiole in dorsal view.

Eguchi, Bui and Yamane (2011) - The worker of Vollenhovia is easily separated from those of other known Vietnamese myrmicine genera by the flattened body and the posterodorsal margin of petiole produced as a rim.

Taxonomic Notes

Eguchi, Bui and Yamane (2011) - Workers of Vietnamese species have the following features. Worker monomorphic; head in full-face view subrectangular; frontal carina and antennal scrobe absent; median portion of clypeus raised, laterally margined with a slight to conspicuous longitudinal carina; anteromedian portion often forming a transverse strip; an isolated median seta absent; posteromedian portion relatively narrowly inserted between frontal lobes; lateral portion of clypeus never modified into a distinct ridge or wall in front of antennal insertion; mandible triangular; masticatory margin with 6 or more teeth; antennae 11- or 12-segmented, with 3-segmented club; eye always present, small to medium sized; mesosoma in lateral view long and low; promesonotum in lateral view usually not domed; promesonotal suture absent dorsally; metanotal groove weakly to slightly impressed dorsally; posterodorsal portion of propodeum with rounded corners or small teeth; propodeal lobe present as carina or low lamella; petiole nodiform; anterior peduncle short and obscure; posterodorsal margin of petiole produced posterodorsad as a rim which is distinctly (or at least a little) higher than the dorsal outline of helcium of petiole when waist segments stretched posteriad; subpetiolar process usually (but not always) developed as a large lamella; gastral shoulder absent.
