Synonyms

=  Chrysopa diploa  Navás, 1935

The listed synonymy of C. diploa is that of Hölzel & Ohm (1992).

Diagnosis

This is one of four species of Dichochrysa found in Madagascar.  Dichochrysa superficially looks like several other genera, including Apertochrysa, but male genitalia contains a tignum.  The genus is closely related to Mallada, males of which also have a tignum, and is generally separated by other components of the male genitalia: in Dichochrysa the male ectoproct is only moderately elongate and has an apodeme that extends to the callus cerci, and the sternite 8+9 is simple and without dorsal stalked setae at the apex.

Some of the Madagascar species of Dichochrysa have distinctive small dark spots at the base of the forewing.  The most distinctive feature of this species is the veins of the distal cubital cell (dcc) of the forewing are swollen and darkened, in contrast with the green veins of the rest of the wing.     

 This species has dark at the clypeal margin, dark palpi, red spot on the gena, pale antennae, and a red spot at the hind margin of the vertex near the eyes.  There is a dark lateral stripe on the pronotum.  There are small dark spots at the base of both the forewing and hindwing.  There are four dark inner gradates that extend far basally.     

          The nominate subspecies, D. duplicata duplicata, can be distinguished from the other two subspecies by the presence of small dark spots at the base of both fore and hind wings, and the presence of green gradate veins.  It is found only on mainland Madagascar.  (Hölzel and Ohm, 2000).
