Camponotus efitra species group
Based on Rasoamanana and Fisher 2022.
Species
Identification
Key to Malagasy Camponotus subgenus Mayria minor workers
Diagnosis
The efitra group is characterized by the color and sculpture of its integument; and a convex promesonotum separated from the propodeum by a weak metanotal suture.
Major and Minor workers - In profile, metanotal suture impressed, the propodeal dorsum forming a separate convexity from a domelike promesonotum, dorsum of propodeum below level of promesonotum. Clypeus evenly convex to straight in profile, its anterior margin convex to broadly triangular, not projecting, posterior margin weakly notched medially, major worker with massive mandible, occipital portion asetose, few standing setae present between frontal carinae but moderately present on clypeal dorsum and malar area. Petiole nodiform. Color brown. Integument sculpture finely imbricate to glabrous, apparently shiny.
Minor worker - In full-face view, head subovate with strongly convex posterior and lateral sides. Anterior clypeal margin broadly rounded.
Major worker - In full-face view, head roughly quadrate or rectangular, head sides evenly convex (as in C. efitra) to straight (as in C. chrislaini).
Notes
In Rakotonirina, Csősz & Fisher, 2017, C. efitra was considered a member of the grandidieri species group. Here, this species is separated from this group by the form of the mesosoma and the petiolar scale, the type of integument, and the general sculpture of major workers.
