GAUROMYRMEX

(Subfamily Myrmicinae)

Taxonomy

Gauromyrmex was established by Menozzi (1933) and was treated as a junior synonym of Vollenhovia by Brown (1973) and subsequent authors, but revived and assigned into the Nesomyrmex genus group of the Formicoxenini by Bolton (2003).

Bionomics

All of known species of Gauromyrmex are arboreal (Bolton, 2003). Brühl (2003) reported that an undetermined Bornean species of the genus builds nest using resin on tree trunks at a height of about 15 to 18 m from the bases. The nests had a grayish, hard surface and were smoothly attached to the bark of the trees. A few tiny holes about one millimeter wide led inside the nest. Within the nest were many hollows and recognizable tunnels. There were between two and four nests of varying sizes on a tree trunk suggesting a possible polydomous colony structure.
