( Figs 18View FIGURES 15–18, 27View FIGURES 22–27, 42View FIGURES 41–44, 55View FIGURES 54–57, 72, 85, 104, 108, 120)

Amblycerus cuernavacensis Romero et al. 1996  (desc., type, distr., key); Romero et al. 2002 (phyl.).

Type material. The species was recognized through its original description and illustration of the male genitalia ( Romero et al. 1996). Specimen identified by Romero and Kingsolver (below) was also examined.

Additional specimens examined. [1 male specimen]: Ajijic, JAL., MEX.\ 13 May, 1964\ WLNutting\ at lt. 5140’; Amblycerus  sp. ♀ [handwritten symbol]; Amblycerus  \ cuernavacensis\ det. R. J. + K.\ J. M. Kingsolver; Amblycerus cuernavacensis  \ Romero, Johnson and Kingsolver, 1996 \ Det.: A. T. Santos;\ C. S. Ribeiro-Costa, 2017. ( FSCA).

Measurements. BL: 6.8 mm; BW: 3.9 mm.

Diagnosis ( Figs 29View FIGURES 28–31, 104View FIGURES 103–106). Amblycerus cuernavacensis  is characterized by the following characters combination: pronotum subtrapezoidal in dorsal view with five dense strips of setae ( Fig. 55View FIGURES 54–57); internal sac of male genitalia with a pair of hollow, subquadrate, tuberculate sclerites in the apical region and median region with an unpaired trapezoidal sclerite ( Fig. 104View FIGURES 103–106). The species differs from A. spondiae  by the lateral carina reaching the posterior margin of pronotum (almost reaching the posterior margin of pronotum in A. spondiae  ), cervical boss with two setae (three setae in A. spondiae  ) and scutellum tridentate with all teeth with about the same length (median tooth longer in A. spondiae  ). Amblycerus cuernavacensis  can be distinguished from A. alternatus  by the distinct frontoclypeal suture (indistinct in A. alternatus  ), lateral carina reaching the posterior margin of pronotum (almost reaching in A. alternatus  ) and scutellum tridentate with all teeth with same length (median tooth longer than the lateral ones in A. alternatus  ). Finally, the species can be distinguished from A. vitis  by the subquadrate and tuberculate apical sclerite (subtriangular, non-tuberculated in A. vitis  ) and in median region, where A. cuernavacensis  has an unpaired, subtrapezoidal sclerite, whilst A. vitis  has a long wishbone sclerite.

Distribution ( Fig. 120View FIGURES 120–121). Mexico.
