Calosoma (Carabomimus) orizabae (Jeannel, 1940)

Length 22 mm. From the state of Vera Cruz (Orizaba), Jeannel had described, on a single specimen, Carabomimus orizabae, that he assumed must have been captured on the slopes of the volcano Orizaba.
The type specimen, object of the description, has its penis of the same model than C. striatulum, albeit with apex slightly thicker, the body is slightly longer, the elytra more elongated (although the proportions given by Jeannel: "three times longer than wide " are exaggerated) and without trace of striae.
This specimen would have been found in a not too well defined locality but surely inside the same vast region where also C. striatulum lives. Note that of this last species some new medium altitude populations have recently been discovered. These populations consist of individuals having morphological characteristics in some respect similar to the holotype of C. orizabae namely dimentions lightly larger than normal (20-22mm) and almost smooth elytra, but with wider pronotum and less slend shape.
One more female individual has been later identified in the collection of the Muséum National d'Histoire Naturelle in Paris. This individual, however, was collected far away, in the state of Guanajuato, most probably in the nineteenth century and, unfortunately, given its gender, it is not possible to use the characteristics of the genitals to verify its systematic placement.
Gidaspow (1959: 289) did not see this species and no more specimens are known. Therefore, we remain uncertain as to its true systematic position and actual distribution.

Examined specimens
Mexico. Vera Cruz: Orizaba (holotype MNHN); Guanajuato (det. Ball; MNHN)

Notes: Brachypterous. According to Erwin (2007: 99), it lives around 1250 m altitude. No more information is available.
