"Colombie/Funck [locality in error]," 1 ♀ (holotype) ( IRSNB); Mexico, Hidalgo state., km 170, carretera 105, 7 km N Tlanchinol , 21°3'5"N, 98°40'4"W, 1300 m, 22 vii 1992, leg. A. Maya, E.

González-Soriano, 1 ♀ ( RWG), Puebla state, 1 km SE Atepatahua, 20° 0' 50" N, 97° 29 3' 11" W, 650 m, 27 viii 2007, E. González-Soriano, 1♂ ( CNIN); Veracruz State., El Muro, km 14 carretera 131 Tlapacoyan-Altotonga , ca. 19° 52' 41.0" N, 97° 13' 40.6" W, 1100 m, 17 viii 1996, R. Novelo-Gutierrez, 1♂ ( INECOL) .

Diagnosis. The relatively unmodified pronota in males ( Figs. 1–2 ) and females ( Figs. 7–8 ), long paraprocts and medial quadrate lobe along medial 0.40 of cercus in males ( Figs. 24 , 28 , 32–34 ) uniquely distinguish this most northerly species of the genus.

Dimensions. Males (n = 5): Hw 34–37 (35.8); abdomen 38.5–42 (40.6); total length 48.3–55 (51.2). Females: (n = 3 including holotype): Hw 34-37 (35.8); abdomen 32.5-42.0 (40.6); total length 48.3-55.0 (51.2).

Distribution. Hidalgo, Oaxaca, Puebla and Veracruz States, Mexico ( Fig. 41 ).

FIGURES 14–17. wings.

Remarks. González-Soriano & von Ellenrieder (2009) noted differences among scattered populations in Mexico where specimens differ slightly in male pronotal ( Figs. 1–2 ), cercal ( Figs. 32–34 ) and in female pronotal ( Figs. 7–8 ) morphology. They believed these differences corresponded to intraspecific morphological variation related to geography rather than representing specific characters of distinct species. Synthoracic patterns may also differ between the sexes; males have more extensive black areas on synthorax, especially dorsally, where an inverted wedge-shaped incomplete pale antehumeral stripe of variable length occupies the lower 0.5 to 0.7 basal portion of the mesepisternum. In females, dorsal black may be limited to a mid-dorsal stripe with an incomplete dark humeral stripe occupying the upper third of humeral suture.
