Amblycerus goianiensis Santos & Ribeiro-Costa  , sp. n.

( Figs 14View FIGURES 9–14, 27View FIGURES 22–27, 40View FIGURES 35–40, 53View FIGURES 48–53, 70, 83, 96, 102, 119)

Type. Holotype deposited in DZUP, male, with label: Mineiros—GO\ X-1994 \ Magno Col. 

Diagnosis ( Figs 96View FIGURES 91–96). Amblycerus goianiensis Santos & Ribeiro-Costa  , sp. n. is very similar externally and in relation to genitalia to A. insuturatus  , from which it differs by the frontoclypeal suture distinct (indistinct in A. insuturatus  ), cervical boss with four setae (three setae in A. insuturatus  ), the last ventrite almost twice as long as the ventrite IV (almost as long as ventrite IV in A. insuturatus  ), internal sac of male genitalia in the apical region with a subtriangular sclerites (with a pair of ovoid sclerites in A. insuturatus  ), unpaired median subtrapezoidal sclerite (unpaired wishbone sclerite in A. insuturatus  ).

Description. Measurements. BL: 7.9 mm; BW: 4.6 mm.

Integument color ( Figs 14View FIGURES 9–14, 40View FIGURES 35–40, 83View FIGURES 78–83). Body red, except by light red antennae.

Vestiture ( Figs 14View FIGURES 9–14, 27View FIGURES 22–27, 40View FIGURES 35–40, 53View FIGURES 48–53, 83View FIGURES 78–83). Body covered with orange setae. Pronotum and elytra uniformly orange. Scutellum light yellow. Pygidium with median stripe of light yellow.

Head ( Fig. 27View FIGURES 22–27). Frons covered with fine and moderately dense coarse punctures; without frontal carina. Eyes distant from each other anteriorly, ocular index: 3.0; ocular sinus: 1.3. Postocular lobe 0.3 times the eye length. Antennae reaching anterior margin of hindcoxae; serrated from antennomeres 4–10; antennomere 7 about 1.4 longer than wide, last antennomere subelliptic. Frontoclypeal suture distinct. Clypeus covered with fine and moderately coarse punctures except by a narrow apical area. Labrum with few fine punctures on basal margin. Prothorax ( Fig. 53View FIGURES 48–53). Pronotum trapezoidal with lateral margins slightly curved, covered laterally by coarse and dense punctures ( Fig. 53View FIGURES 48–53); lateral carina almost reaching the posterior margin of pronotum; cervical boss with four 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 14View FIGURES 9–14, 40View FIGURES 35–40, 70). Scutellum about 1.5 longer than wide, tridentate in apical margin, median tooth longer than the lateral ones (Fig. 70). Elytra with striae strongly impressed, all free apically ( Fig. 14View FIGURES 9–14). Metepisternum with moderately coarse and sparse punctures ( Fig. 40View FIGURES 35–40); metepisternal sulcus with transverse axis gently oblique; the longitudinal axis about half the length of metepisternum. Metaventrite not prominent in lateral view, without punctures and with median sulcus longer than a half the lenght of metaventrite ( Fig. 40View FIGURES 35–40). Metacoxae with coarse punctures ( Fig. 40View FIGURES 35–40). Hindtibia with lateral spur about twice the length of median spur ( Fig. 40View FIGURES 35–40). Abdomen ( Figs 40View FIGURES 35–40, 83View FIGURES 78–83). Ventrites without moderately coarse punctures ( Fig. 40View FIGURES 35–40); last ventrite almost twice as long as the ventrite IV. Pygidium with apical margin rounded and with dense and moderately coarse punctures ( Fig. 83View FIGURES 78–83).

Male genitalia ( Figs 96View FIGURES 91–96, 102View FIGURES 97–102). Median lobe of male genitalia about 4.2 times times as long as its greatest width at apical region ( Fig. 96View FIGURES 91–96). Ventral valve with lateral margins almost straight and acuminate apex. Dorsal valve subtriangular, with lateral margins almost straight, rounded apically. Internal sac in the apical region with a pair of hollow, ovoid, tuberculate sclerites ( Fig. 96View FIGURES 91–96). Median region with a pair of blades serrate at lateral margin; with unpaired wishbone sclerite. Tegmen with moderate, rounded, emargination between the enlarged lateral lobes ( Fig. 102View FIGURES 97–102). Female. Unknown.

Distribution ( Fig. 119View FIGURE 119). Brazil (Goiás).
