Welcome to the new AntWeb!

We here at AntWeb have been busy working on our newest (and most ambitious) version of the site - and there are lots of great new things! Which means there are lots of changes (don't worry, they're all for the best).

And we've put together a handy little guide to show you all the new features and enhancements - why don't you have a quick look to check out all the new features and enhancements?

Mandibles with distinct tooth in their basal margin, at or near midlength. Palp formula 1, 1 (Bolton, com. per.). Anterior margin of the clypeus without tooth. [Hypostomal tooth not observed]. Mesosoma slightly convex. Metanotal groove deep. Lateral sides of pronotum sharply angulated. Propodeal spiracle rounded, large, away from propodeal margin. Propodeum sloping with two stout short spines directed outward and backward, broadly separated between him. Propodeal lobe subtriangular. Petiole with node long. Head, thorax, petiole and postpetiole with numerous punctures, most separated by at least one puncture diameter; some small areas reticulo-punctated: between frontal carinae, in the center of promesonotal area, dorsal one third of propodeum; roughly sculptured on petiole. Several long and flexuous white hairs on body. Scape with several median suberect hairs, each scape with two long flexuous hairs. Body black, gaster dark brown, legs and antennae lighter.
Queen and male: Unknown.
Material examined: PAPUA NEW GUINEA : 2 workers, Wau N, on Bulolo Ridge, B- 278, 650 m , 1974 , S. Peck leg. ( BMNH ).
