Nomenclature

The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

  • laevidens. Calyptomyrmex (Dicroaspis) cryptocerus var. laevidens Santschi, 1919h: 88 (w.) DEMOCRATIC REPUBLIC OF CONGO. Combination in Dicroaspis: Bolton, 1981a: 59. Raised to species: Bolton, 1981a: 59.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

Description

Worker

Bolton (1981) - TL 2.5-2.6, HL 0.72, HW 0.62-0.64, CI 86-88, SL 0.44-0.46, SI 72-73, PW 0.46-0.48, AL 0.74 (2 measured).

Gross characters as given under the generic diagnosis (see Dicroaspis) and answering to the description of Dicroaspis cryptocera, but with the differences noted in the key (see identification above).

Apart from this laevidens is a somewhat smaller (compare measurements), more heavily sculptured version of cryptocera. Sculptural differences are in intensity rather than form; on the promesonotum the low rugae tend to enclose numerous reticular spaces or foveolate spaces, and on the first gastral tergite the piligerous punctures form broad but shallow conspicuous pits. Eye-size is about the same as in cryptocera, with maximum diameter 0.06 (0.09-0.10 x HW), with 3 ommatidia in the longest row.
