Acrotaphus amazonicus Pádua & Sääksjärvi  sp. n.

( Figs 18–26View FIGURES 18–27)

Diagnosis. This species can be distinguished from all other Acrotaphus  by the combination of the following characters: 1) margin of gena behind eyes concave (flat in male) in dorsal view; 2) posterior ocelli separated from eyes by 0.3–0.5× its diameter in dorsal view; 3) metasoma orange with distal half of tergite V and tergites VI+ black or tergites V+ black; 4) hind leg entirely black, except the base of coxa orange or orange with apex of coxa, femur, tibia and tarsus black; 5) ovipositor robust, 1.3–1.5× as long as hind tibia.

Description. Female. Body [18.0] 13.0–18.0 mm. Head. Lower face [0.9] 0.8–1.0× as broad as high (from supraclypeal suture to base of antenna), flat, with scattered punctures which bear long conspicuous bristles; head in dorsal view with margin of gena concave behind eyes; margin of gena [0.5] 0.5–0.7× length of eye in dorsal view; posterior ocelli separated from eyes by [0.3] 0.3–0.5× its diameter in dorsal view. Mesosoma. Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.5] 0.5–0.7× distance from tegula to hind margin of propodeum; mesoscutum smooth and polished, with notaulus weakly marked; scutellum in dorsal view triangular; mesopleuron polished, with fine bristles anteriorly and ventrally; epicnemial carina present ventrally, extending until reaching the level of the lower corner of the pronotum laterally; metapleuron polished, with sparse, fine bristles evenly spaced and with a strongly longitudinal groove in lower part below spiracle; propodeum smooth dorsally, laterally with scattered fine bristles. Fore wing [12.8] 10.5–13.0 mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.7] 0.6–0.9× as long as abscissa of M between 2 rs-m and 2 m-cu; hind wing with abscissa of Cu 1 between M and cu-a [1.0]× length of cu-a. Tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe. Metasoma. Tergite I [1.7] 1.45–1.9× as long as posteriorly broad; tergite II [1.3] 1.1–1.6× as long as posteriorly broad; tergite III [1.3] 1.1–1.6× as long as posteriorly broad; tergites IV–V [1.4] 1.0–1.4× as long as posteriorly broad; ovipositor robust, [1.6] 1.4–1.7× as long as hind tibia; lower valve with slightly swelling in the base and mid region.

Coloration. Head black, mouthparts orange, except apex of mandible black; antenna brownish. Mesosoma entirely orange. Metasoma orange, with weakly blackish marks on the posterior margin of tergites II–IV, tergite V with distal half black and tergites VI+ black.Anterior and mid leg entirely orange, the hind leg orange, with trochantellus, femur, tibia and tarsus black. Wings yellowish; fore wing with apex distal to 2 rs-m black, and with a black median band extending backwards from anterior margin, just proximal to the pterostigma, right through the 1 st subdiscal cell; pterostigma yellowish. Ovipositor brownish and sheath dark brown.

Male. ( Figs 21–22View FIGURES 18–27). Similar to female in structure and coloration, except body 7.0–10.0 mm; lower face 1.0– 1.2× as broad as high (from supraclypeal suture to base of antenna); head, in dorsal view, with margin of the gena flat behind the eyes; margin of the gena 0.5–0.6× length of eye, in dorsal view; posterior ocelli separated from eyes by 0.4–0.6× its diameter in dorsal view; fore wing 6.0–7.0 mm; tergite I 1.2–1.5× as long as posteriorly broad; tergite II 1.4–1.5× as long as posteriorly broad; tergite III 1.2–1.4× as long as posteriorly broad; sternite IX ( Fig 24View FIGURES 18–27) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin flat and posterior margin slightly concave centrally, with few bristles widely spaced posteriorly. Genital capsule ( Figs 25–26View FIGURES 18–27): Paramere truncated apically, slightly narrower than the parameral lamina, with bristles except in posterior margin; volsellar lamina with spaced bristles laterally and apically on the central region and with a set of four to five bristles in anterolateral region, just below the base of the digitus; cuspis robust with about five to six teeth aligned in the mid part until apex and with some small bristles in basal region and about five small bristles spaced laterally in apical region; digitus with teeth on apex, rounded distally and angular ventrally, with the margins of the apical region narrower than base; aedeagus with few teeth on apex and its apex slightly curved downward in lateral view.

Variation. Some specimens (found from the same locality as the holotype) have margin of gena slightly concave behind eyes; pronotum with anterior region blackish; metasoma orange with tergites V+ or VI+ black; hind coxa slightly blackish, except its base orange or coxa orange, except its apex blackish. Note: We have not treated those females and males into the paratypes. They are listed in other material.

Biological notes. Host unknown.

Etymology. The specific name refers to Amazonia.

Comments. Acrotaphus amazonicus  sp. n. closely resembles A. fasciatus (Brullé, 1846)  and A. pseudoamazonicus  sp. n. mainly by having last metasomal tergites black and hind leg orange with femur, tibia and tarsus blackish or hind leg entirely black. It differs from A. fasciatus  by having margin of gena behind eyes concave and posterior ocelli separated from eyes by 0.3–0.5× its diameter in dorsal view (margin of gena behind the eyes strongly concave and posterior ocelli separated from eyes by 0.1× its diameter in dorsal view in A. fasciatus  ). It differs from A. pseudoamazonicus  sp. n. by having margin of gena behind eyes concave (margin of gena behind eyes flat in A. pseudoamazonicus  sp. n.).
