Calosoma (Callisthenes) fischeri (Fischer von Waldheim, 1842)

Length 17-21 mm. C. fischeri is easily spotted among the other species of Callisthenes because its pronotum has the front sides considerably projecting in relation to the head. Moreover, it is an unique species because of its vibrant colours, not present in other species of the subgenus.
It spreads into Centre and South-West of Mongolia.

Johann Gotthelf Fischer von Waldheim (1771-1853) was born and studied in Germany and later became director of the Natural History Museum at the Moscow University, and founder of the Société Impériale des Naturalistes de Moscou. He gave in its publication of 1842 a schematic description of this species, of which he attributed the authorship to Édouard Ménétries (1802-1861), another important entomologist of French origin. However, Ménétries formalized his description only the following year (1843: 347), so the species is named in honor of Fisher although he also appears as its author.
