Jamapa, Veracruz - Fig. 36). Paratype specimens examined from Mexico were distinctly smaller (but similar in coloration), accounting for the large size variance in the description of the species. Material examined from Mexico was limited, and thus it is difficult to assess the significance of the size variation observed in Mexican specimens. Compared to the paratype specimens from Mexico, the Costa Rican specimens have the apex of the phallobase slightly more elongate (Fig. 17B), the ventral lobe of the inferior appendage slightly more produced (Fig. 17A), the basomesal process of the inferior appendage more distinctly rounded (Figs 17A, 17D), and the mesal process of tergum X shorter (Fig. 17A). Mexican specimens were variable for most of these characters, especially in the development and angulation of the phallobase, without much evidence that this was anything more than intraspecific variation. A close side-by-side comparison reveals that specimens from Mexico and Costa Rica are very similar, especially when the variation among Mexican specimens is taken into account. In the absence of specimens from the intervening area between Mexico and Costa Rica and evidence to the contrary, this variation is here considered intraspecific.
