Acrotaphus zampieronae Pádua sp. n.

( Figs 222–226 )

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) posterior ocelli separated from eyes by 0.1–0.3× its diameter in dorsal view; 3) body entirely reddish orange; 4) hind leg entirely reddish orange or reddish orange, with femur, tibia and tarsus blackish; 5) ovipositor robust, 1.4–1.7× as long as hind tibia.

Description. Female. Body [14.3] 9.0– 16.5 mm. Head. Lower face [0.8] 0.7–0.9× 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 the gena flat behind the eyes; margin of the gena [0.4] 0.3–0.5× length of eye in dorsal view; posterior ocelli separated from eyes by [0.1] 0.1–0.3× its diameter in dorsal view. Mesosoma. Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.5] 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. Fore wing [12.0] 8.0–14.0 mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.8] 0.7–1.0× 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 [1.4] 1.0–1.4× length of cu-a. Tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe. Metasoma. Tergite I [2.0] 1.3–2.0× as long as posteriorly broad; tergite II [1.6] 1.1–1.6× as long as posteriorly broad; tergite III [1.5] 1.0–1.5× as long as posteriorly broad; tergites IV–V [1.5] 1.0–1.5× as long as posteriorly broad; ovipositor robust, [1.4] 1.4–1.7× as long as hind tibia; lower valve with slightly swelling in the base and mid region.

Coloration. Head black, mouthparts reddish orange, except apex of mandible black; antenna brownish. Mesosoma and metasoma entirely reddish orange. Anterior and mid leg entirely reddish orange, hind leg reddish orange, except femur, tibia and tarsus blackish. Fore wing with apex distal to 2 rs-m slightly black, and with a slightly black median band extending backwards from anterior margin, just proximal to the pterostigma, right through the 1 st subdiscal cell; pterostigma yellowish. Ovipositor reddish orange and sheath dark brown.

Male. Unknown.

Variation. Some specimens have the margin of gena behind eyes slightly concave in dorsal view; fore wing with cu-a more or less opposite to base of Rs&M; hind leg reddish orange except distal half of femur, tibia and tarsus blackish.

Biological notes. Host unknown.

Etymology. The specific name, in apposition, refers to Sônia Lúcia Modesto Zampieron for her dedication to the dissemination of science in the city of Passos/MG and region.

Comments. Acrotaphus zampieronae sp. n. closely resembles A. ferruginosus , A. fascipennis , A. chedelae and A. japi mainly by having metasoma entirely reddish orange. It differs from A. ferruginosus and A. japi by having margin of gena behind eyes flat (gena strongly concave, in A. ferruginosus and A. japi ) and from A. chedelae by having margin of of gena <0.5× length of eye in dorsal view and posterior ocelli separated from eyes by <0.3× its diameter in dorsal view (margin of the gena>0.6× length of eye, in dorsal view and posterior ocelli separated from eyes by>0.4× its diameter in dorsal view in A. chedelae ) and from A. fascipennis by having ovipositor>1.4× as long as hind tibia (ovipositor 1.1× as long as hind tibia, in A. fascipennis ).
