Aguiar, Alexandre P. & Santos, Bernardo F., 2012, Additions to the revision of Digonocryptus Viereck (Hymenoptera, Ichneumonidae, Cryptinae), with nine new taxa, new males, and distribution maps for all known species, Zootaxa 3282, pp. 1-41 : 9-10

Digonocryptus denticulatus ( Taschenberg, 1876)

Morphological variation. This is a very regular species. Considering the new distribution record reported here, which expands the known latitudinal distribution of the species to 15.04 degrees (1,671 km), it seems impressive that specimens from these two extremes show only one visible difference: the petiole apex and T2 base are dark brown for northern specimens, vs. lighter brown in the south.

Although a common event in Digonocryptus, Aguiar and Ramos (2011) have not demonstrated that the males of D. denticulatus are generally much smaller than females. For the present work, the length of the fore wing varied from 5.11–8.22 mm (only smallest and largest specimens measured) which is approximately about half of that known for the female (7.2–14.7 mm).
