Camponotus sanctaefidei convexinodis

Identification
This form might, perhaps, be regarded as a distinct species. In the structure of the petiole it closely resembles Camponotus bidens, but in most other respects it agrees with sanctaefidei, and the following variety seems clearly to represent a transition between the two forms. (Wheeler 1934)

Worker
minima Length 2.7-3.5 mm.

Head without the mandibles, distinctly broader than long, broad anteriorly, as in darlingtoni, but the eyes further back, as in the typical form of the species. Teeth on the epinotum not flattened, longer, stouter and more elevated at their tips, with a much broader excision between their bases. Petiole unlike that of any of the preceding forms of the species and like that of C. bidens, the anterior and dorsal surfaces not separated by a ridge but forming in profile a single convex surface, the superior border with a short, acuminate, median tooth like that of bidens.

Head, thorax and petiole more opaque than in the typical form and darlingtoni, but the sculpture as in the former. Pilosity and pubescence white, the hairs longer and more abundant on the head, thorax and gaster than in any of the preceding forms; pubescence long and sparse, conspicuous over the whole dorsal surface of the head, not appressed but merging into the pilosity. Black; scapes and trochanters yellow; mandibles, borders of cheeks, funiculi, neck and legs reddish yellow; coxae dark brown; last funicular joint and a streak along the flexor surface of the middle and hind femora brownish.
