Comments.
This species was described in detail by
Karny (1929)
, although, unfortunately, there are no data on the precise localities of the
type
specimens, so the distribution of this species is incomplete on
Map 1
, since it can extend even farther south and to the north, in contrast to the records documented here.
In the distribution range, based on the observed specimens, three variations or color forms are differentiated (
Map 1
, see the color code on each locality): 1) The body is yellowish (except for the head, which will always be black in all color forms) and the median ocellus red, as observed in the
holotype
of
Ecuador
(
Fig. 1
) and Colombian specimens from Circasia, Quindío department and Manizales, Caldas department. 2) The body is pink similar to the median ocellus. This color form was recorded at Cali-Dagua road in the Department of Valle del Cauca (
Fig. 2
). 3) Pink medan ocellus, green legs, pronotum, and abdomen yellowish, with diffuse pink spots. This color form was observed in only one specimen from Chinchina, Caldas (
Fig. 3
). It is currently unknown if these color forms are regional (although the yellowish form 1 is more widely distributed than the other two color forms) or are conditioned by the micro-habitat and food where the populations live.
