ETYMOLOGY. This species is named after the Maya   civilization, which in Pre­ Colombian times occupied areas that include the most northern parts of the range of its distribution.

DESCRIPTION. Dimensions. See Table I. Morphology. Ninth sternite ( Fig. 34 View FIGURE 34 ): abruptly narrowed at apex. Tenth tergite ( Fig. 23 View FIGURES 18 ­ 25 ): posterior margin trilobulate; medial lobe subtriangular, broader than long. Gonocoxite ( Figs. 33­34 View FIGURE 33 View FIGURE 34 ): distal half bifurcated; dorsal branch bearing a tuft of stout hairs, the three longest at its posterior margin; ventral branch with one long and stout hair at apex; other hairs long and slender. Gonostylus ( Figs. 15 View FIGURES 14 ­ 17 , 33­34 View FIGURE 33 View FIGURE 34 ): with two strongly sclerotized apical extensions ( Fig. 15 View FIGURES 14 ­ 17 , III and IV), the apicalmost (extension IV) slightly longer and broader than the other; posterior margin constricted at base, dilated at apex; thin hairs spread along most distal parts of lateral face. Aedeagal sheath ( Figs. 33­34 View FIGURE 33 View FIGURE 34 ): without lateral lobes; dorsal crest two­pointed, with points disposed side by side; ventral branches long, broad at base, abruptly narrowed at tip. Female cercus: narrowing gradually toward tip; ventral margin gently curved, not constricted.

REMARKS. Charles Paul Alexander insisted in associating specimens of this species with S. americana   (e. g. Alexander, 1945 b: 241 ( Figure 8 View FIGURES 8 ­ 9 ), 264; Alexander, 1947: 356 (List of Species)), without, however, clarifying the grounds on which these associations were based. The examined specimens of this new species deposited at USNM were all identified by Alexander as belonging to S. americana   .
