( Figs 176–184 View FIGURES 176–185 )

Diagnosis. This species can be distinguished from all other species of Acrotaphus by the combination of the following characters: 1) margin of gena behind eyes flat in dorsal view; 2) margin of gena 0.35–0.5× (0.5–0.6 in male) length of eye in dorsal view; 3) posterior ocelli separated from eyes by 0.3–0.5× its diameter in dorsal view; 4) metasoma orange with posterolateral bands in the tergites II–IV, tergite V with distal half and VI+ black; 5) hind leg entirely black, except the base of coxa orange or orange, with apex of coxa, femur, tibia and tarsus black; 6) ovipositor robust, 1.1–1.5× as long as hind tibia.

Description. Female. Body [11.0] 10.5–15.0 mm. Head. Lower face [0.8] 0.75–1.0× 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 flat behind eyes; margin of gena [0.45] 0.35–0.5× length of eye in dorsal view; posterior ocelli separated from eyes by [0.4] 0.3–0.5× its diameter in dorsal view. Mesosoma. Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.4] 0.4–0.5× 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.

Genital capsule ( Figs 183–184 View FIGURES 176–185 ): 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 about four to five bristles in anterolateral region, just below the base of the digitus; cuspis robust with about five teeth aligned in the mid part until apex and with about six few bristles in basal region and spaced laterally on apical region; digitus with teeth on apex, rounded distally and angular ventrally, with the margins of the apical region narrower than base; aedeagus with small teeth on apex and its apex slightly curved downward in lateral view.

Variation. Some specimens have the pronotum with anterior margin blackish; metasoma orange with tergites V+ or VI+ black or orange, with tergites II–IV with posterior margin black; hind coxa entirely black or orange, except apex blackish.

Biological notes. Two males were found from the nest of the Trypoxylon (Trypargilum) lactitarse Saussure, 1867 (Crabronidae) . See above under the biological notes of A. franklini .

Etymology. The specific name refers to the similarity with the species A. amazonicus sp. n..

Comments. Acrotaphus pseudoamazonicus sp. n. closely resembles A. fasciatus (Brullé, 1846) and A. amazonicus 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 flat and posterior ocelli separated from eyes by 0.3–0.5× its diameter in dorsal view (margin of gena behind eyes strongly concave and posterior ocelli separated from eyes by 0.1× its diameter in dorsal view, in A. fasciatu s), differs from A. amazonicus sp. n. by having margin of gena behind eyes flat (margin of gena behind eyes concave, in A. amazonicu s sp. n.).
