Spermophagus dispar Sharp, 1885: 494  (desc., distr.). For review of literature, see Ribeiro-Costa et al. (2018).

Types. The species was recognized through its original description and works by Ribeiro-Costa ( Ribeiro-Costa 1995; Kingsolver & Ribeiro-Costa 1997) that illustrated the male genitalia and examined the type material of A. dispar  as well as of its synonyms, with the exception of Spermophagus thomasi  . For the synonymical list of A. dispar  , see Ribeiro-Costa et al. (2018).

Tucumán \ TUCUMAN-ARGEN- TINA; FML; Amblycerus dispar  \ ( Sharp, 1885)\ Det.: A. T. Santos; C. S. Ribeiro-Costa, 2017. ( FML).

Diagnosis. Amblycerus dispar  is characterized by the following combination of characters: eyes closer to each another anteriorly, ocular index: 9.5 ( Fig. 23View FIGURES 22–27); median lobe of male genitalia about 4.5 times as long as its greatest width at apical region and internal sac at the apical region without sclerites ( Fig. 92View FIGURES 91–96). It differs from A. schwarzi  by the presence of a frontal carina (absent in A. schwarzi  ), cervical boss with three setae (two setae in A. schwarzi  ), metaventrite with median sulcus longer than a half the length of the metaventrite (about half the length of the metaventrite in A. schwarzi  ), last ventrite almost as long as ventrite IV (almost two times as long as ventrite IV in A. schwarzi  ) and internal sac of male genitalia without a pair of sclerite at the apical region (one pair in A. schwarzi  ). Amblycerus dispar  can be futher separated from A. crassipunctatus  by the presence of frontal carina (absent in A. crassipunctatus  ), eyes closer to each other anteriorly ( Fig. 23View FIGURES 22–27) (distant in A. crassipunctatus  ), and metaventrite with median sulcus longer than a half the length of metaventrite (about half the length of metaventrite in A. crassipunctatus  ).

Redescription. Measurements. BL: 7.9 mm; BW: 4.0 mm.

Integument color ( Fig. 10View FIGURES 9–14). Red to dark red.

Vestiture ( Figs 10View FIGURES 9–14, 36View FIGURES 35–40, 49View FIGURES 48–53, 79View FIGURES 78–83). Body covered with light yellow setae. Pronotum with six vaguely dense patches and a median basal line of setae. Elytra with setae uniformly distributed; pygidium with median stripe of setae.

Head ( Fig. 23View FIGURES 22–27). Eyes approximate anteriorly, ocular index: 9.5, ocular sinus 1.3 and postocular lobe about 0.4 the eye length. Frons covered with fine and moderately dense coarse punctures, with frontal carina. Antennae reaching anterior margin of hindcoxae, serrate on antennomeres 4–10; antennomere 7 about 1.5 longer than wide, last antennomere subelliptic. Frontoclypeal suture distinct. Clypeus covered with moderately coarse punctures, except near apex, where it is smooth. Labrum with few fine coarse punctures on basal margin. Prothorax ( Figs 36View FIGURES 35–40, 49View FIGURES 48–53). Pronotum trapezoidal with lateral margins slightly curved, covered entirely by coarse and dense punctures ( Fig. 49View FIGURES 48–53); lateral carina almost reaching posterior margin of pronotum; cervical boss with three setae; cervical sulcus conspicuous behind eyes. Prosternal process longer than anterior coxae, gently arched between coxae and slightly constricted between coxae. Meso- and metathorax ( Figs 2View FIGURES 1–8, 10View FIGURES 9–14, 36View FIGURES 35–40, 63, 64). Scutellum about 1.7 longer than wide, tridentate, median tooth longer than the lateral ones ( Figs 2View FIGURES 1–8, 63, 64). Elytra with striae strongly impressed, at basal third striae 1–6 with punctures more isolated, 6–7 striae fused apically ( Fig. 10View FIGURES 9–14). Metepisternum without coarse punctures; metepisternal sulcus with transverse axis gently oblique or straight; the longitudinal axis about half the lenght of metepisternum. Metaventrite not prominent in lateral view, without punctures and median sulcus longer than a half the lenght of metaventrite ( Fig. 36View FIGURES 35–40). Metacoxae with coarse punctures. Hindtibia with lateral spur about 2.8 times the length of median spur. First tarsomere about 1.6 the length of the lateral spur and 4.5 times the length of median spur. Abdomen ( Figs 36View FIGURES 35–40, 79View FIGURES 78–83). Ventrites with moderately coarse punctures ( Fig. 36View FIGURES 35–40); last ventrite almost as long as ventrite IV. Pygidium with apical margin rounded and with coarse and dense punctures ( Fig. 79View FIGURES 78–83).

Male genitalia ( Figs 92View FIGURES 91–96, 98View FIGURES 97–102). Median lobe of male genitalia about 4.5 times as long as its greatest width at apical region ( Fig. 92View FIGURES 91–96); ventral valve with lateral margins concave and acuminate apex; dorsal valve subtriangular, with lateral margins almost straight. Internal sac in the apical region without sclerites, some small spines dispersed ( Fig. 92View FIGURES 91–96). Median region with J-shaped unpaired sclerite, two vertical lines of denticles, two groups of denticles, and two laminar hat-shaped sclerites with denticles at apex. Basal region with several small denticles close to ejaculatory duct. Tegmen with deep, rounded emargination between the enlarged lateral lobes ( Fig. 98View FIGURES 97–102). Female. Similar to male except ventrite V not emarginate.

Distribution ( Fig. 117View FIGURES 117–118). Curaçao, Honduras, Panama, Venezuela, French Guiana, Brazil (Pará, Mato Grosso, Ceará, Paraíba, Pernambuco, Bahia, Rio de Janeiro), Peru, Paraguay (new country record), Argentina and Chile.

Life History. According to Johnson et al. (2001), the larvae of A. dispar  feed only on one seed during their entire development, while in other species of the genus it is common to find one larva feeding on several seeds during their development.
