Variation. Prepectal carina reaching 0.90–0.95 of distance to subtegular ridge ( vs. reaching subtegular ridge); second recurrent vein meeting areolet at middle ( vs. apical 0.3–0.4); first and second intercubiti about same length ( vs. first intercubitus shorter than second); nervellus intercepted a little above its middle ( vs. at middle); wings apically light infuscate ( vs. hyaline); hind femur dorsally light brown ( vs. black); hind tibia basally blackish ( vs. entirely yellow); T3 basally blackish, centrally light brown, apically yellow ( Fig. 4F ) ( vs. basally black, apically yellow); T4–8 basally light brown ( Fig. 4F ) ( vs. black).

Distribution. Mexico (Cordoba, Nuevo Leon, Orizaba, Quintana Roo NR, San Rafael, Sinaloa NR, Tamaulipas, Vera Cruz, Veracruz, Yucatan) ( Fig. 18H ). Bootstrap analysis suggests that this species occurs typically between 100–500 m, like most Agonocryptus spp. ( Fig. 20B ).
