Diagnosis.This species can be distinguished from all other species of Acrotaphusby the combination of the following characters: 1) margin of gena behind eyes flat in dorsal view; 2) margin of gena 0.6–0.8× length of eye in dorsal view; 3) posterior ocelli separated from eye by 0.6–0.8× its diameter in dorsal view; 4) metasoma orange with posterior margin of tergite V and tergites VI+ black; 5) ovipositor 1.0–1.3× as long as hind tibia.
Description.Female. Body [12.0] 9.0–12.0 mm. Head.Lower face [1.0] 1.0–1.05× 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 flat behind eyes; margin of gena [0.8] 0.6–0.8× length of eye in dorsal view; posterior ocelli separated from eyes by [0.7] 0.7–0.8× its diameter in dorsal view. Mesosoma.Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.5]× 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 [10.5] 8.5–10.5 mm; cu-aopposite to the base of Rs&M; 2 rs-m[0.6]× as long as abscissa of Mbetween 2 rs-mand 2 m-cu; hind wing with abscissa of Cu1 between Mand cu-a[0.8] 0.8–0.9× length of cu-a. Tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe. Metasoma.Tergite I [1.4] 1.0–1.4× as long as posteriorly broad; tergite II [1.1] 1.0–1.2× as long as posteriorly broad; tergite III [1.0] 1.0–1.2× as long as posteriorly broad; tergites IV–V [0.9] 0.9–1.1× as long as posteriorly broad; ovipositor robust [1.0] 1.0–1.3× as long as hind tibia; lower valve with slightly swelling in the base and mid region. Coloration.Head black, except apical margin of clypeus slightly yellowish, mouthparts orange, except apex of mandible black; antenna brownish. Mesosoma orange, except anterior region of pronotum blackish. Metasoma orange, with posterior margin of tergite V and tergites VI+ black. Anterior and mid leg entirely orange, the hind leg orange, with femur, except base, tibia and tarsus blackish. Wings yellowish; fore wing with apex distal to 2 rs-mblack, and with a black median band extending backwards from anterior margin, just proximal to the pterostigma, right through the 1 stsubdiscal cell; pterostigma yellowish. Ovipositor brownish, except basal region orange and apex slightly brownish, sheath dark brown. Male.( Figs 11–12). Similar to female in structure and coloration, except body 9.0–11.0 mm; lower face 1.1– 1.2× as broad as high (from supraclypeal suture to base of antenna); head in dorsal view with margin of gena flat behind eyes; margin of gena 0.6–0.8× length of eye in dorsal view; posterior ocelli separated from eyes by 0.85× its diameter in dorsal view; fore wing 7.0–9.0 mm; tergite I 1.1–1.4× as long as posteriorly broad; tergite II 1.0–1.1× as long as posteriorly broad; tergite III 0.9–1.3× as long as posteriorly broad; sternite IX ( Fig 14) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin flat and posterior margin concave centrally, with few bristles widely spaced posteriorly. Genital capsule ( Figs 15–16): Paramere truncated apically, slightly narrower than the parameral lamina, with bristles except in posterior margin; volsellar lamina with spaced bristles medially and apically, except in the inner margin and posterior part and with a set of three 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 two to four few bristles in basal region and spaced laterally in apical region; digitus with teeth in 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 with hind femur with proximal half orange and distal half black or hind femur orange with distal 0.4 black.

Distribution. Braziland Peru( Fig 17). Biological notes.Host unknown.
Etymology.The specific name (in apposition), refers to type locality ( holotype) of this specimen-type, Amajari, Roraima, Brazil.
Comments. Acrotaphus amajari sp. n.closely resembles A. chedelae Gauld, 1991mainly by the coloration, margin of gena flat behind eyes and margin of gena 0.6–0.8× length of eye in dorsal view. It differs from it by having ovipositor <1.3× as long as hind tibia (ovipositor>1.4× as long as hind tibia in A. chedelae).
