Calosoma (Castrida) abbreviatum Chaudoir, 1869

Calosoma abbreviatum Chaudoir, 1869: 371 (described from: Perou ou Bolivie); original material 1♂ (ex coll. Laferté); holotype ♂ (no locality label) designated by Deuve (1978: 249) by monotypy in Muséum National d'Histoire Naturelle, Paris [examined]

Length 23-26 mm. C. abbreviatum is easily recognizable because of the shape of its pronotum which is twice or more than twice as wide as it is long, narrowed in its rear part. The metatrochanter are rounded but in male, in some case, they are slightly pointed at tip. Moreover the second segment of the anterior tarsi of males does not have the depression on dorsal side, typical of the other species of subgenus Castrida. The color is dark bronze.
The type of C. abbreviatum is dubitatively indicated as coming from Peru or Bolivia. Many later authors therefore include Bolivia in the distribution area of this species, although there is no other indication of findings in this country. What is certain is that C. abbreviatum is widespread in north western South America, extending from Peru to the north up to Ecuador and Colombia.
C. abbreviatum prefers bush covered plains, sandy areas and cultivated land (Erwin, 2007: 85), and is therefore considered to be one of the species that possibly shall expand its range toward Central America following the destruction of forests (Erwin, 1991: 23).

Notes: Winged, after the rains is often attracted to light at night (Jeannel, 1940: 98). Preferably lives in lowlands, and active adults have been noted in the raining season from November to April (Erwin, 2007: 85).
