Didigua nigridorsum sp. n.


Didigua nigridorsum

13mm. This species is very close to effusa and martini, and is distinguished only by characteristics of the male. The hindwing is excavated in a similar manner to that of martini, but with the anterior angle of the excavation less produced. The dorsal zone is folded under to enclose a large, blackish brush of hair-scales, observed from the dorsal surface as a somewhat darkened ridge. The male genitalia are very similar to those of martini except in the aedeagus vesica where the most basal two spines are set on a lobe near the central one, rather than on the main tube halfway between the central spine and the base of the vesica.
