Length 13-17 mm. C. morelianum, as C. politum, has slightly arched pronotum sides and it is characterized by a rounded apex of penis
Carabomimus morelianum, has been described from Huitzilac. This locality, and the others in which the species has been collected by us and those cited in the literature are included in a relatively small area on the border between the states of Mexico and Morelos. Its descriptor (Bates, 1891: 228) considered morelianum as a subspecies of C. diminutum (= C. politum). For our part, while we consider C. politum and C. diminutum as conspecific, we prefer to consider morelianum as a distinct species because of the constantly smaller size, the pronotum with scattered punctures on its rear part, the more marked microsculpture, less glossy aspect, almost glazed, The sculpture of elytra, with surface strigulose and covered with larger points and because of the differences in the shape of the apex of penis that is slightly less elongated.
From the surroundings of Ciudad de Mexico , Rotger (1976) has described Calosoma (Carabomimus) cicatricosum balli, which, according to the description and the accompanying images can be considered synonymous to morelianum, as also confirmed by Lassalle (2009: 6).
From the western Mexico state, morelianum goes further south to the Morelos. It is unlikely its presence in the state of Vera Cruz, as reported by Gidaspow, based on a dubious quote from Bates (1891).

Examined specimens and literature’s data
Mexico D F: El Guardia, 3000 m (SB), La Marquesa (SB); Mexico: San Nicolás Coatepec 2500 m (GP), Santa Marta, Ocuilan 2700m (EM, SB), 1ml. from Santa Marta, Ocuilan (paratype cicatricosum balli, UNAM); Morelos: Huitzilac (lectotype morelianum, MNHN).

Notes: Notes: Brachypterous. Nocturnal. It has been found under stones, on field and pastures on the fringe of woodland, in June-July, but according to Erwin (2007: 101) it is also active in May.
