Dicroaspis laevidens

Nothing is known about the biology of .

Identification
D. laevidens is one of a pair of species in the genus Dicroaspis.


 * Piligerous punctures on basal portion of first gastral tergite effaced, barely visible. Propodeal dorsum in profile without a peak in the outline before sloping to the spines. Slightly larger species, HL 0.80-0.86, AL 0.86-0.92. (Zaire, Principe I.) . . . . . Dicroaspis cryptocera


 * Piligerous punctures on basal portion of first gastral tergite coarse, broad and conspicuous. Propodeal Qorsum in profile with a peak in the outline before sloping to the spines. Slightly smaller species, HL 0.72, AL 0.74. (Gabon, Zaire) . . . . . Dicroaspis laevidens

Nomenclature

 *  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.

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.

Type Material
Bolton (1981) - Syntype workers, ZAIRE: Yambuya, 26.xi.1913, no. 83 (Bequaert) (, Tervuren; NM, Basle) [examined].
