Calosoma (Calosoma) aurocinctum Chaudoir 1850

Calosoma aurocinctum Chaudoir

Calosoma splendidum Perbosc, 1839:261. [Holotype female, MEXICO, Santa Domingo (MNHP).]

Calosoma aurocinctum Chaudoir, 1850:420. [New name for C. splendidum Perbosc, 1839:261, not Dejean.]

DIAGNOSTIC COMBINATION.—Pronotum without basal seta at hind angle; venter brilliant metallic, pronotum bluish green, not contrasting with elytra. Color and luster: bluish green, elytra often dark green with purple or golden margin, femur blue, tibiae and tarsi black. Form: size medium large, head and pronotum narrow relative to broadly inflated elytra; eyes large and prominent Structure: pronotum with sides evenly and markedly arcuate, small pointed hind angles, without basal setae; elytra serrate or not near humerus, with striatopunctate interneurs, punctures connected by shallow scaly cross lines, intervals convex; middle tibia markedly arcuate in male, slightly arcuate in female; male foretarsi with four dilated articles, each with spongy pubescence beneath. ABL = 22.0 to 30.0 mm; 10.0 to 14.0 mm (from Gidaspow, 1959).

GEOGRAPHICAL DISTRIBUTION.—Although Gidaspow (1963) reported this species from Nicaragua, I have seen no specimens from there and she does not give, in her paper, a list of depositories associated with each species. As several southern Mexican records are available, I have no doubt that this species could inhabit Central America.

NATURAL HISTORY.—Unknown.

MATERIAL EXAMINED.—Type (see above) and 10 specimens from Mexico.
