Diagnostic remarks

Stamnodes cassinoi is not easy to distinguish from S. annellata and S. costimacula . Males can be separated from those of S. costimacula by their filiform and non-bipectinate antennae. Generally, the basal half of the hindwing underside is darker brown than in S. annellata and S. costimacula , and the costal margin at the antemedian often has a noticeable semicircular ochreous patch. Genitalic dissection (Matson & Wagner in prep.) and genetic analysis are sometimes necessary to distinguish this taxon from others.

Distribution

Mexico: Stamnodes cassinoi is found in the chaparral associations, foothills, canyons, and Pacific coastal scrub communities of northwestern Baja California. USA: the core of this species’ range lies in California. Stamnodes cassinoi appears to prefer more coastal habitat than congeners and rarely ranges inland.

Biology

Stamnodes cassinoi feeds on Cercocarpus betuloides in southern California and likely Mexico. There is a single flight, from early December through January, with mature caterpillars following into March. The caterpillar and host plant were discovered by David L. Wagner and the author in March 2016 in southern California. Additional unpublished life history details and larval illustrations are forthcoming (Matson & Wagner in prep.).

Molecular characterization

This species is represented in BOLD as BIN: BOLD:AAF9456 (n = 10). At present, the average pairwise intraspecific distance is 0.59%, the pairwise maximum intraspecific distance is 1.12%, and the distance to the nearest neighbour, Stamnodes modocata (n = 2), is 4.67%.
