REMARKS. The collected gynandromorph of this species had a mosaic structure (Figs

1–3). The head was generally male-like (including the tridentate mandibles) except the antennae which were female-like (they had ten flagellomeres and a length typical of the female). It was hardly possible to ascertain the sex-type of the thorax due to its poor sexual dimorphism in this species but the legs were definitely male-like (claws were bifurcate in all the pairs of legs). The metasoma was generally female-like expect the pilosity which was male-like both dorsally (apical bands of the terga were not as strong as in the female) and ventrally (scopa was replaced by sparse long bands of setae). The genitalia were female-like.

The specimen bore deutonymphs of a symbiotic mite species.
