Zumatrichia palmara Flint 1970

Zumatrichia palmara

This undescribed species, although distantly related to Z. anomaloptera Flint, is extremely distinctive. The shape of the process from the lateral margin and the midventral lobe of the eighth sternum, the long basodorsal process of the claspers, the structure of the apex of the aedeagus, and the lack of modification of the forewings will serve to characterize this species.

ADULT.—Length of forewing, 2.5–3 mm. Coloration typical pattern of grayish green and fuscus. Male genitalia: Eighth sternum with an elongate dorsolateral process which bears an apical, stout, angled seta; midventrally produced into a broad nearly truncate lobe. Ninth segment with anterolateral angle, broadly produced; posterolateral lobe slender, with a single large apical seta. Lateral penis sheath, narrowed and truncate apically, slightly longer than broad; constricted subapically in ventral aspect. Clasper with a straight, slender basodorsal process, ventral lobe elongate, slightly inflated apicad, halves widely separated in ventral aspect. Aedeagus with short, pointed basolateral plates, a long, tonguelike middorsal process, and a pair of long, slender, ventromesal spines which bear a basolateral scalelike process.
