Diagnostic remarks

This species is easily confused with sympatric S. formosata , but Stamnodes lampra is smaller than S. formosata , has darker brown scaling at the forewing apex and darkened costomedial area, and beneath, the forewing apical area and hindwing are typically striated with rust and light brown scales that stand in opposition to S. formosata ’s bright red scales of the same areas.

Distribution

Mexico: Stamnodes lampra inhabits the rocky hillsides, open woodlands, and chaparral communities of the northern Sierra Madre Occidental. USA: Stamnodes lampra is relatively uncommon in the Madrean Sky Islands of southeast Arizona.

Biology

The peak adult flight occurs in July and August with larvae to follow. Larvae are hosted by alder leaf mountain mahogany ( Cercocarpus montanus ). The caterpillar and host plant were discovered by David L. Wagner and the author in September 2018 in southeast Arizona. Additional unpublished life history details and larval illustrations are forthcoming (Matson & Wagner in prep.).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:AAM3494 (n = 4). At present, the average pairwise intraspecific distance is 0.08%, the maximum pairwise intraspecific distance is 1.93%, and the distance to the nearest neighbour, Stamnodes coenonymphata (n = 26), is 4.33%.
