Camponotus convexiclypeus Mackay, W.P., 1997 |
Known only from the queen holotype, nothing is known about the biology of Camponotus convexiclypeus.
Identification
A member of the subgenus Myrmostenus.
MacKay (1997) - This is a large species with a head much wider than in the other species in the subgenus (2.52 mm vs. 1.44- 2.00 mm in all other species in the subgenus). The clypeus is strongly convex as seen from above. It has the usual coarse hairs on the vertex and also on the underside of the head.
This species appears to be related to Camponotus sphenocephalus, as the vertex is rounded and the head is densely punctate as in C. sphenocephalus. The head is wider as seen in full face view, thus making it easily separated from C. sphenocephalus.

Description
Queen
HL 3.76, HW 2.52, SL 3.76, EL 0.98, clypeus length 1.52, clypeus width 1.22. Indices: SI 100, CI 67, clypeal index 80.
Mandible with 6 teeth and an angle at basal margin; clypeus longer than wide, strongly convex (Fig. 3); anterior clypeal border concave with two lateral lobes; scape extending about 1h length past posterior border of head; head flattened in profile; vertex convex; maxillary palps short, about 1.4 length of distance to foramen magnum; labial palps also short, about V3 length of maxillary palps; mesosoma lengthened as in other species; propodeum with poorly defined angle between two faces, posterior face appearing much shorter than basal face; petiole thin, with convex anterior face and straight posterior face (Fig. 2).
Hairs sparse, but coarse, some bent at angles and long (0.70-0.90 mm), area from vertex to upper edge of frontal carinae with about 20 coarse hairs, clypeus without hairs except for fringe at anterior border, about 20 hairs on underside of head, scapes with scattered erect hairs, up to 0.25 mm in length, dorsum of mesosoma with about 20 hairs, propodeum at point where faces meet with 6 hairs on left side, three on right side, node of petiole with three hairs on left, one on right, gaster with scattered hairs at the edges of each tergum but also on the other surfaces; decumbent pubescence almost absent.
Sculpture coarse on bead, consisting of dense punctures, similar to that of C. sphenocephalus, remainder of body smooth and shining.
Color medium brown, head, including mandibles, scapes and funiculi, darker brown.
Type Material
Holotype 9, Peru, Monson Valley, Tingo Maria, 11-XII-1954; E. I. Schlinger & E. S. Ross collectors.
Etymology
Refers to the strongly convex clypeus.
