Calosoma (Carabosoma) glabratum Dejean 1831

Calosoma glabratum Dejean

Calosoma glabratum Dejean, 1831:565. [Lectotype male, COLOMBIA (Goudot) (MNHP), herein selected.]

Calosoma bolivianum Géhin, 1885:65. [Type, male, “Bolivia” as originally given by Gelun (MNHP).]

DIAGNOSTIC COMBINATION.—Middle tibia straight (as in Figure 8); pronotum with angulate lateral margins, angles rounded, basal seta absent; elytral intervals flat, intemeurs shallowly striatopunctate; metatrochanter unisetose, round at tip; head finely and densely punctate. Color and luster: black, venter dark brown. Form: size small, head and pronotum narrow relative to broadly inflated elytra; eyes large and prominent. Structure: pronotum with sides obtusely angulate, small pointed hind angles, without basal setae; elytra serrate near humerus, with fine striatopunctate intemeurs, punctures connected by shallow scaly cross lines at base, intervals flat; middle tibia straight in male and female; male foretarsi with three dilated articles, each with spongy pubescence beneath. ABL = 18.5 mm; TW = 8.0 to 10.5 mm (from Gidaspow, 1963).

GEOGRAPHICAL DISTRIBUTION.—Gidaspow (1963) indicated that she saw specimens from Panama; however, I could not locate these specimens, and I have seen no other records of this species from Central America. Otherwise, the species has a known range extending from Bolivia north to Colombia.

NATURAL HISTORY.—Members of this species are found in cultivated lands and in natural grasslands. They are fully winged and probably are strong flyers as are other members of the genus.

MATERIAL EXAMINED.—Types (see above) and 4 specimens from Colombia.

Calosoma glabratum is a species of ground beetle in the subfamily of Carabinae. It was described by Pierre François Marie Auguste Dejean in 1831.
