Description
Cabera nevillei is a medium-sized Cabera species. The forewing is which is broad and pointed, with length ranging from 15–16 mm in males, and 16–17 mm in females. . The hindwing resembles the forewing, except it has a shorter point at the anal angle. Adults are on wing in February, April, May, October and December.[1]
It is morphologically similar to its sister species Cabera toulgoeti and Cabera limbata . From the former, it can be differentiated on the basis of having less prominent discal spots on the upperside of forewings. Furthermore, the underside bears striking resemblance of each, however, the terminal shade appears more developed in C. nevillei when observed closely. The genitals also differ in size and structure. The socci are shorter with a more curved aedeagus as compared to C. toulgoeti.[3][4]
From C. limbata, it is distinguished on its genitals. There are five conuti on the aedeagus, instead of a single one in the latter species. Occasionally, C. nevillei has more prominent and well-defined markings. Notably, one of the male paratypes exhibits partial albinism, where much of the violaceous-grey coloration in the postmedian areas of both pairs of wings is replaced by a whitish-grey hue.[4]
