Calosoma (Callisthenes) mirificum Casale, 1979

Callisthenes regelianus mirificus Casale, 1979: 80 (Massiccio del Paropamisus, Sabzak pass 2500m., coll. Casale)
Callisthenes mirificus Obydov, 1999:132

Length 33-35 mm. C. mirificum was described as a subspecies of C. regelianum, but later Obydov (1999b) has revaluated it as distinct species.
C. mirificum is easily distinguishable from C. regelianum because of the large size, unusual for a Callisthenes, and because of the relatively more developed and more massive head and pronotum. The elytra have an evident groove in their suture, which on the contrary is not always visible in C. regelianum. The pronotum has almost parallel sides; the elytra are heavily punctate with transverse creases along the groove in the suture, more accentuated in the back half.
Three specimens are known, all female, from the same locality in western Afghanistan.

Examined material
Afghanistan: Paropamisus mountain range, Sabzak pass 2500m. (coll. Casale)

Notes: Brachypterous. It has been found under stones near the snow line around 2500m. altitude. Adults were collected on two occasions only, in March and June.
