Stagmomantis nahua Saussure, 1869

Taxonomic history. Described as Stagmomantis nahua by Saussure (1869). Synonym: Oromantis (Stagmomantis) nahua (given in Giglio-Tos 1917, 1927).

Distribution. Mexico through Central America to Colombia (Ehrmann 2002; Agudelo et al. 2007).

Species description. Saussure (1869); Saussure and Zehntner (1894), brief; Giglio-Tos (1927), as Oromantis; Rehn (1935b), brief.

Features. S. nahua is relatively short for this genus (Table 2). Male features: forewings are hyaline, being totally membranous, not reaching the end of the abdomen; marginal strip of forewings is hyaline or subhyaline; hindwings are dark or dusky; edges of the pronotum are denticulated (Giglio-Tos 1927; Rehn 1935b). Female features: forewings are relatively short, with the marginal field running evenly down the wings; hindwings have a yellow anterior with a dark posterior, or being ochreous-yellow and opaque; stigma is not differentiated in color from the forewing (Latin concolore); edge of the pronotum is very densely and finely denticulated at the metazone (Saussure and Zehntner 1894; Giglio-Tos 1927; Rehn 1935b). Brown individuals may have a dark spot on the inner surface of the anterior femora; green individuals tend to lack this marking (Rehn 1935b).
