WORKER - similar to procerus, TL 13.6-14.6 mm;
mandibles subtriangular, head narrower, scapes longer, petiole longer
than broad. Colour black (Bolton, 1975b: 13, not illustrated).
Collected by the Lang & Chapin expedition of 1910.
Santschi (1923e) noted (my translation) "the example shown by Wheeler
(1922, p 90-91, fig 17) has the head with much longer antennae than procerus,
of which I have a co-type, sent by Emery (figure of which was used by
Emery in Genera Insectorum). P. wheeleri differs on the
other hand from longiscapus Santschi by the striations of the
postpetiole, which are transverse with the former and longitudinal in
the latter. The procerus is stockier and more similar to obesus
Wheeler but that is larger".
Bolton's modern description (1975b) is at . Bolton (1975b) also reported examining
material from Cameroun, Avom (G. Terron, shown below) and
indicated that a
female may be among the 1910 material.
