Taxonomic act

Stamnodes similis syn. nov. is newly regarded as a synonym of S. ululata . In the original description of S. similis, Wright describes this taxon as most closely resembling S. apollo and makes no mention of S. ululata . It is unlikely Wright compared the holotype female of S. ululata to his S. similis material, for had he done so, at the very least he would have had to mention their uncanny similarity. COI barcodes and genitalic preparations of S. similis specimens at the USNM are identical to those of S. ululata . Doug Ferguson in Furniss et al. (1988) entertained this taxonomic change but did not make an explicit call for synonymy.

Diagnostic remarks

Stamnodes ululata is one of only a few species of Stamnodes known to be sexually dimorphic. The male antennae are bipectinate with ciliated rami; those of the female are filiform. In males, the forewing apex, costa, and costomedial subquadrangular patch are darkened with brown-grey scales, while in females, these areas are much lighter and given towards clay. The female hindwing underside is also nearly immaculate, and only occasionally shows a very slight, medial, transverse colour transition.

Distribution

Mexico: Stamnodes ululata 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 to the north in California.

Biology

Adults precede larvae in the fall, flying from September to November across most of the range. Males rarely come to light according to McFarland (1965). Larvae are hosted by birch leaf mountain mahogany ( Cercocarpus betuloides ). In Furniss et al. (1988), Douglas Ferguson attributed the original host record of this species to reared adults from Chris Henne records in the Los Angeles County Museum (LACM). Additional unpublished life history details and larval illustrations are forthcoming (Matson & Wagner in prep.).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:AAL9317 (n = 21). At present, the average pairwise intraspecific distance is 1.31%, the pairwise maximum intraspecific distance is 2.75%, and the distance to the nearest neighbour, Stamnodes costimacula (n = 13), is 7.35%.
