Calosoma (Ctenosta) planicolle Chaudoir, 1869

Calosoma planicolle Chaudoir, 1869: 369 (description compatible with one specimen only, from: Zambéze); holotype ♀ designated by Deuve (1978: 250) by monotipy in Muséum National d'Histoire Naturelle, Paris [examined]
Calosoma procerum Harold, 1881: 260 (described from: “Taita und Ukamba”, as taken from the title of the publication) original material and depository not stated
Calosoma (Ctenosta) planicolle Breuning, 1927: 188
Ctenosta planicolle Jeannel, 1940: 130

Length 30-40 mm. The sculpture of the elytra in this species, as it happens in C. senegalense, is characterized by the tertiary intervals that are more elevated than the others (heterodynamic sculpture) and deeply incised. The primary and secondary ones instead consist of rough grains.
However, despite a superficial likeness with C. senegalense, C. planicolle can be recognized because of the glossy black color of the upper body with foveae of the primaries of the same color, the larger dimensions and, any way, examinig the metatrochanters that have a rounded tip in both sexes.
C. planicolle can be found in most sub-Saharan African countries from Niger to the horn of Africa, including Madagascar.
