Amblycerus simulator ( Jacquelin Du Val, 1857) 

( Figs 21View FIGURES 19–21, 34View FIGURES 32–34, 47View FIGURES 45–47, 60View FIGURES 58–60, 77, 90, 113, 116, 122)

Spermophagus simulator Jacquelin Du Val, 1857: 167–168  (desc., distr.). For review of literature, see Ribeiro-Costa et al. (2018).

Type material. The type material was requested from the MNHN, but it was not found by the curator. The recognition of A. simulator  was done by its original description, comparison with material previously identified by comparison with the type material by J. M. Kingsolver, and a work that illustrated the male genitalia ( Ribeiro-Costa 1995)  .

Additional specimens examined. [1 male specimen]: Faz. Nova Orlandia\ Jataí, Go—Brasil\ I. 964—Martins,\ Morgante & Silva.; Dep. Zool.\ São Paulo; Amblycerus  \ simulator\ (Jac-Duv)\ det.\ J. M. Kingsolver; Amblycerus simulator  \ (Jacquelin Duval, 1857)\ Det.: A. T. Santos; C. S. Ribeiro-Costa, 2018. ( MZSP). [1 female specimen]: Faz. Aceiro ♂ [symbol handwriting]\ Jatai, Goiás—Brasil\ X. 1962 \ Exp. Dep. Zool.; Dep. Zool.\ São Paulo; Am- blycerus\ simulator\ (Jac-Duval, 1857)\ Ribeiro-Costa, C.

Diagnosis ( Figs 34View FIGURES 32–34, 47View FIGURES 45–47, 77, 90, 113). Amblycerus simulator  is characterized by the following characters combination: head entirely covered by fine punctures ( Fig. 34View FIGURES 32–34); eyes closer to each other anteriorly ( Fig. 34View FIGURES 32–34), ocular index: 7.5; antennomere 7 about 1.1 longer than wide; scutellum about 6.3 longer than wide, bidentate (Fig. 77); longitudinal axis of metepisternal sulcus one-fourth the length of metepisternum ( Fig. 47View FIGURES 45–47); basal tarsomere about 2.6 the length of the median spur ( Fig. 47View FIGURES 45–47); pygidium with apical margin subtruncated ( Fig. 90View FIGURES 88–90); median lobe of male genitalia about 6.1 times as long as its greatest width at apical region ( Fig. 113View FIGURES 111–113); internal sac in the apical region with elongate unpaired sclerite in form of an inverted “V” in lateral view ( Fig. 113View FIGURES 111–113); median region with a subcylindrical unpaired sclerite and a pair of short, angulate sclerites. The species was similar to no other of the genus.

Redescription. Measurements. BL: 6.7 mm; BW: 3.5 mm.

Integument color ( Figs 21View FIGURES 19–21, 47View FIGURES 45–47, 90View FIGURES 88–90). Dorsum and abdomen red; head and ventral region of thorax dark red or entirely deep red.

Vestiture ( Figs 21View FIGURES 19–21, 47View FIGURES 45–47, 60View FIGURES 58–60, 90View FIGURES 88–90). Body covered with light yellow and brown setae. Pronotum and elytra mottled with light yellow and brown setae uniformly distributed. Scutellum light yellow. Ventral region with dark integument mottled with gray and brown setae. Pygidium with median faint stripe of light yellow.

Head ( Fig. 34View FIGURES 32–34). Frons covered with fine punctures, without frontal carina. Eyes strongly prominent laterally, closer to each other anteriorly ( Fig. 34View FIGURES 32–34), ocular index: 7.5; ocular sinus: 1.6 and postocular lobe about 0.2 the eye length. Antennae not reaching anterior margin of hind coxae, serrate from antennomeres 4–10 ( Fig. 47View FIGURES 45–47); antennomere 7 about 1.1 longer than wide, last antennomere subelliptic. Frontoclypeal suture indistinct. Clypeus covered with fine punctures, except for narrow region at apex. Labrum with few fine punctures on basal margin. Prothorax ( Fig. 60View FIGURES 58–60). Pronotum trapezoidal with lateral margins strongly curved, covered laterally by coarse and dense punctures; lateral carina reaching posterior margin of pronotum; cervical boss with two setae; cervical sulcus conspicuous behind eyes. Prosternal process expanded beyond anterior coxae, curved and gently constricted between coxae. Meso- and metathorax ( Figs 21View FIGURES 19–21, 47View FIGURES 45–47, 77). Scutellum about 6.3 longer than wide, bidentate (Fig. 77). Elytra with striae strongly impressed, all free apically ( Fig. 21View FIGURES 19–21). Metepisternum with moderately coarse and sparse punctures ( Fig. 47View FIGURES 45–47); metepisternal sulcus with transverse axis gently oblique; longitudinal axis about one-fourth the length of metepisternum. Metaventrite not proeminent in lateral view, without punctures and median sulcus longer than a half the lenght of metaventrite ( Fig. 47View FIGURES 45–47). Metacoxae with coarse punctures ( Fig. 47View FIGURES 45–47). Hind tibia with lateral spur about 1.8 times the length of median spur ( Fig. 47View FIGURES 45–47). Basal tarsomere about 1.4 times the length of lateral spur and 2.6 times the length of median spur. Abdomen ( Figs 47View FIGURES 45–47, 90View FIGURES 88–90). Ventrites with moderately coarse punctures ( Fig. 47View FIGURES 45–47); last ventrite almost twice as long as the ventrite IV. Pygidium with apical margin subtruncated and with coarse and sparse punctures ( Fig. 90View FIGURES 88–90).

Male genitalia ( Figs 113View FIGURES 111–113, 116View FIGURES 114–116). Median lobe of male genitalia about 6.1 times times as long as its greatest width at apical region ( Fig. 113View FIGURES 111–113). Ventral valve with lateral margins concave and acuminate apex; dorsal valve subtriangular with lateral margins almost convex. Internal sac on the apical region with elongate unpaired sclerite in form of an inverted “V”, in lateral view ( Fig. 113View FIGURES 111–113). Median region with subcylindrical unpaired sclerite, a pair of blades serrated on lateral margin and at apex, and a pair of short, angulate sclerites. Tegmen with shallow emargination between the enlarged lateral lobes ( Fig. 116View FIGURES 114–116). Female. Integument brown, excepted for blackish frons and hind legs; ventrite V not emarginated and pygidium with apex obtuse.

Distribution ( Fig. 122View FIGURE 122). Cuba, Honduras, Brazil (Mato Grosso, Goiás, São Paulo) and Peru.
