Erythrodiplax chromoptera is a species of dragonfly from the subfamily Sympetrinae . The female was described by Borror in his revision of the genusin 1942and classified in the Basalis group . The male is still unknown to this day. The species occurs from Rio de Janeiro south to just before the Uruguayan border.
features
The female abdomen is between 19.0 and 20.0 millimeters long and yellow-brown. A band to be found on both sides extends over all segments . On the first three segments it is dark brown, then later brownish black. The lateral keel is black. The thorax is yellowish green on the sides; yellow on the underside. The top is greenish brown. Except for the hip ( coxa ), the thigh ring (trochanter) and the back of the thighs ( femora ), which are yellow, the legs are black. On the femora of the last pair of legs there are 14 to 18 spines that get shorter with increasing distance from the body. The head of the dragonfly is red-brown behind and brown-yellow on the front. The wings are transparent, but have a large spot at the base that extends to the nodus . This spot also inspired Borror when it was named. The 3.0 to 3.4 millimeter large wing mark ( pterostigma ) is yellow-brown. The length of the hind wings measures between 21.5 and 23.0 millimeters.
Similar species
Erythrodiplax chromoptera is similar to Erythrodiplax solimaea , although the wing spots on both wings are roughly the same dark. In E. chromoptera, on the other hand, the spot in the fore wing is significantly lighter. E. solimaea also has no continuous lateral stripe on the abdomen.
