Camponotus rectangularis

De Oliveira et al. (2015) found two colonies of C. rectangularis opportunistically nesting in Cecropia pachystachya trees (southwest Bahia, Brazil).

Distribution based on Regional Taxon Lists
Neotropical Region: Belize, Brazil, Costa Rica, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname.

Nomenclature

 *  rectangularis. Camponotus rectangularis Emery, 1890b: 57 (w.) COSTA RICA. [Also described as new by Emery, 1894k: 62.] Combination in C. (Myrmorhachis): Forel, 1914a: 274; in C. (Myrmocladoecus): Emery, 1925b: 167; Wheeler, W.M. 1933a: 63. Current subspecies: nominal plus aulicus, rubroniger, setipes, sordidatus, willowsi.

Worker
Minor. Differing from the typical form of the species and its var. rubroniger Forel in coloration, being deep black, with the exception of the posterior borders of the gastric segments and terminal tarsal joints, which are reddish, and the head, antennal scapes and first funicular joint, which are bright yellowish red. Cheeks, clypeus and mandibles yellow, mandibular teeth reddish. The dorsal surface of the gaster is less opaque and more glossy than in rectangularis and rubroniger, with distinctly longer and denser pubescence and even shorter hairs.

Type Material
A single specimen from Acapulco, Mexico (IV.5.'32). There is in my collection a second specimen taken by Frederick Knab in the same locality.
