Gnamptogenys bruchi (Santschi, 1922) |
Apparently a predator of Trachymyrmex and other leaf cutting ants (Kempf and Brown, 1968:92).
Identification
A member of the hartmoni complex (in the regularis subgroup of the mordax species group). Striate body sculpture with weak transverse impressions; metacoxal process is shaped as a low, triangular lobe; clypeal lamella broadly convex anterad. Kempf (1969) notes Gnamptogenys bruchi as close to Gnamptogenys hartmani and that a synonymy could be possible. He also mentions the variability of the extent of impression of the metanotal groove and discards it as an indicator of species separation. This could very well be only a variant of hartmani but due to differences of sculpture on the posterior petiole face, postpetiolar sternal process and c1ypeal lamella, I have chosen to conserve this name until more material can be studied. The sculpture on the dorsum of the petiole can vary from longitudinal to whorled. (Lattke 1995)
