Copera vittata Selys, 1863

Description
English: Copera vittata, Blue Bush Dart, is a species of damselfly in the Platycnemididae family with abdomen black on dorsum and sides as far as segment 10, which latter is pale blue ; segment 9 has also usually a small apical blue spot, sometimes extending along dorsum half way to base. Males of C. vittata are readily distinguished from other species by the straight anal appendages, the superiors being just half the length of the inferiors, and by the very slight dilatation of the tibire. Females are most easily determined by the divergent spines on the posterior lobe of the prothorax, absent in other species.


ID key: "Anal appendages : superiors pale blue or creamy white, as long as segment 10, conical, depressed, acute and tapered at apex ; inferiors nearly twice the length of superiors, broad at base, tapering to apex and directed obliquely medialwards so as to meet at apices, pale within, blackish-brown externally, a small obtuse spine at the middle of inner border. - Fraser, Odonata vol I, page 199"
