Stagmomantis montana montana Saussure and Zehntner, 1894

Stagmomantis montana sinaloae Rehn 1935

Taxonomic history. Stagmomantis montana was first described by Saussure and Zehntner (1894). Rehn (1935a) recognized two subspecies: S. montana montana and S. montana sinaloae. There are at least seven synonyms for S. montana montana, including Stagomantis androgyna (given in Saussure and Zehntner 1894), Stagmatoptera typhon (given in Rehn 1904a), Auromantis (Stagmomantis) montana (given in Giglio-Tos 1917), Auromantis androgyna (given in Giglio-Tos 1917), Auromantis cinctipes (given in Giglio-Tos 1917).

Distribution. S. montana montana is the more widespread subspecies, occurring from USA and northern Mexico southward to Costa Rica (Ehrmann 2002; Agudelo et al. 2007). S. montana sinaloae appears to be mainly confined to the Mexican state of Sinaloa (Rehn 1935a; Ehrmann 2002).

Species description. Saussure and Zehntner (1894), Giglio-Tos (1927), as Auromantis; Rehn (1935a); Rehn (1935b), brief.

Features. Male features: forewings are hyaline, with a green opaque marginal strip; marginal strip is distinctly wider at the base, describing a concave line; hindwings are colorless (Giglio-Tos 1927; Rehn 1935b). Female features: forewings have broad marginal field; forewings are broadly rounded at apex; hindwings are tessellated with yellow spots; stigma is white; anterior coxa is distinctly dentate (Saussure and Zehntner 1894; Rehn 1935b). S. m. sinaloae is somewhat shorter than S. m. montana (Rehn 1935a), as indicated by biometric data (Table 2). In males, S. m. sinaloae differs from S. m. montana by having more slender forelegs, and having a narrower forewing marginal strip that does not describe a concave line (Rehn 1935a).
