Chimarra (Chimarra) poolei Flint 1981

Chimarra (Chimarra) poolei

This is another species of Chimarra that appears to be restricted to the streams of the higher elevations near Rancho Grande. It is related to C. uara Flint, from which it is most easily distinguished by the lack of a dorsal process from the tenth tergite, and by small differences in the shape of the clasper, especially in posterior aspect.

ADULT.—Length of forewing, 5–6 mm. Color uniformly fuscous. Forewing with bulla involving Rs; hind wing with 4 branches to Rs, and 3 to M. Male genitalia: Ninth segment rounded, and bilobed anteroventrally; with a posteroventral keel; dorsolaterally with a pair of long, slender, semierect process. Tenth tergum membranous mesally, with elongate lateral plates, dorsolateral margin bearing 2 sensillae on a dorsolateral flange. Cercus small, ovate. Clasper short and broad; in posterior aspect with a small dorsomesal point and a narrow, lightly sclerotized vertical plate beneath it; posteroventral margin entire. Aedeagus with apex produced into a pointed ventral lip; with 2 internal subequal spines, a large scabrous pouch and a lightly sclerotized rod and ring basally.
