Diagnosis ( Figs 28View FIGURES 28–31, 103View FIGURES 103–106). Amblycerus alternatus  is characterized by the following characters combination: eyes distant from each other anteriorly, ocular index: 4.6; elytra with dense stripes of setae more conspicuous on interestriae 3, 5, 7 and 9; internal sac of male genitalia in the apical region with a pair of hollow, subtriangular, tuberculate sclerite ( Fig. 103View FIGURES 103–106). Amblycerus alternatus  differs from A. spondiae  by the indistinct frontoclypeal suture (distinct in A. spondiae  ), cervical boss with two setae (three setae in A. spondiae  ), metaventrite with median sulcus about half as long as metaventrite (longer than a half the lenght of metaventrite in A. spondiae  ) male genitalia at apical region with a pair of hollow, subtriangular, tuberculate sclerites (with a pair of hollow, subtriangular not tuberculate sclerites in A. spondiae  ). Amblycerus alternatus  differs from A. vitis  in the apical region of male genitalia, where a pair of subtriangular sclerite is tuberculate in the former species and smooth in the latter, and in the median region, whose unpaired wishbone sclerite is short in A. alternatus  whereas it is longer in A. vitis  . Amblycerus alternatus  differs from A. cuernavacensis  by the indistinct frontoclypeal suture (distinct in A. cuernavacensis  ), lateral carina almost reaching the posterior margin of pronotum (reaching the posterior margin in A. cuernavacensis  ) and scutellum tridentate with median tooth longer than the lateral ones (all teeth with same length in A. cuernavacensis  ).

Distribution ( Fig. 120View FIGURES 120–121). Mexico, Guatemala (new country record), Honduras, Panama, Colombia and Brazil.
