Zumatrichia angulata Flint 1970

Zumatrichia angulata

This species bears a simple basodorsal process from the claspers much like that of the preceding species, however, the shape of the ventral lobe of the claspers, and structure of the aedeagus point to a closer relationship with Z. bifida, new species. The simple, angulate basodorsal process of the claspers and the presence of two pairs of long spines in the aedeagus will serve to distinguish these two species.

ADULT.—Length of forewing, 4 mm. Coloration appearing typical (in alcohol). Male genitalia: Eighth sternum without processes; with a very small apicoventral emargination. Ninth segment with anterolateral angle broadly enlarged; posterolateral process slender, with a single long apical seta. Lateral penis sheadi short; apex nearly truncate, with a broad ventral tooth. Clasper with basodorsal process no longer than lateral penis sheath, simple, with apical half angled ventrad; ventral lobe with posterior margin almost squarely truncate in ventral aspect. Aedeagus with a middorsal rod, widened basolaterally, with 2 pairs of long spines, ventralmost slightly longer.
