Climacia chapini Parfin & Gurney

Figures 3, 6 , 15 , 18–20

The mostly hyaline forewings with narrow, conspicuous radiomedial pigment streaks ( Fig. 15 ) distinguish this species from C. areolaris and C. californica . In lateral view, male terminalia have the posterior border of the ectoproct straight and bearing numerous, coarse, dentigerous-based setae ( Fig. 18 ). The ventral lobe of the ectoproct is triangular in shape and much darker than the dorsal portion and its outer margin also has coarse dentigerous-based setae. Internal spines of the gonarcus complex are broadest anteriorly and taper posteriorly in dorsal view ( Fig. 19 ). Female terminalia have tergite 9 longer than broad in lateral view ( Fig. 20 ). The apex of the gonapophyses curve abruptly posteriad at an angle of approximately 65o with fine serrations dorso-apically.

Parfin and Gurney (1956) described this species from specimens collected in Texas and New Mexico. Subsequently, Penny et al. (1997) reported C. chapini from Oklahoma, and Flint (1998) reported the species from Chiapas, Mexico. In this study, new distribution records for C. chapini were recorded from Durango and San Luis Potosi, Mexico suggesting it occurs throughout much of Mexico. The flight period ranges from April through December. Adults are often co-collected with C. californica where their respective ranges overlap, but they are typically more abundant than the latter species.
