Diagnosis ( Figs 18View FIGURES 15–18, 31View FIGURES 28–31, 74, 106). Amblycerus vitis  is characterized by the following combination of characters: eyes distant from each other anteriorly, ocular index: 2.7 ( Fig. 31View FIGURES 28–31); ocular sinus 2.6 and postocular lobe 0.2 the eye length; antennae long, going beyond the anterior margin of the hindcoxae; prosternal process longer than anterior coxae and slightly constricted between coxae; scutellum 1.3 longer than wide (Fig. 74); elytra with striae strongly impressed ( Fig. 18View FIGURES 15–18); at basal third, striae 2–6 with punctures more isolated; all striae free apically; hindtibia lateral spur about 1.2 times the length of median spur; basal tarsomere about 2.5 times the length of the median spur; pygidium without median strip of setae and with moderately coarse and sparse punctures ( Fig. 87View FIGURES 84–87); median lobe of male genitalia about 4.2 times as long as its greatest width at apical region ( Fig. 106View FIGURES 103–106); internal sac in the apical region with a pair of hollow, subtriangular sclerites ( Fig. 106View FIGURES 103–106). Amblycerus vitis  is similar, in terms of genitalia, to the other three species of the spondiae  group, from which it differs, however, because it has the apical sclerite subtriangular, non-tuberculate, with straight apex (subtriangular and tuberculate in A. alternatus  ; subquadrate, tuberculate in A. cuernavacensis  , and subtriangular, non-tuberculate and curved apically in A. spondiae  has subtriangular not tuberculate but with acute apex); on the median region, A. vitis  shows a long unpaired wishbone sclerite ( A. alternatus  and A. spondiae  have a short, wishbone and A. cuernavacensis  has a subtrapezoidal sclerite).

Distribution ( Fig. 121View FIGURES 120–121). United States (Arizona and Texas).

Life History. Amblycerus vitis  larvae feed on only one seed during their development, and pupate inside that seed ( Johnson & Kingsolver 1975). This contrasts with the common condition in this genus, where most larvae of species consume several seeds during their development ( Johnson et al. 2001). Apparently, A. vitis  is univoltine (i.e., has only one generation per year) and is confined to one host ( Johnson & Kingsolver 1975). According to the Johnson & Kingsolver (1975), Urosigalphus  sp. ( Hymenoptera  : Braconidae  ) is a parasite of A. vitis  .
