Acrotaphus homeofranklini Pádua sp. n.

( Figs 102–105 )

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 0.3–0.5× length of eye in dorsal view; 3) posterior ocelli separated from eyes by 0.2–0.3× its diameter in dorsal view; 4) mesosoma orange, with propleuron, pronotum, mesoscutum, basal half of the scutellum and mesopleuron, except posterior margin black; 5) hind leg entirely black or with proximal half of the femur brownish; 6) ovipositor robust, 1.3–1.5× as long as hind tibia.

Description. Female. Body [12.4] 12.0–15.0 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 gena flat behind eyes; margin of gena [0.4] 0.3–0.5× length of eye in dorsal view; posterior ocelli separated from eyes by [0.3] 0.2–0.3× 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 [11.5] 11.0–15.0 mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.6] 0.6–0.85× 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 [1.6] 1.5–1.7× as long as posteriorly broad; tergite II [1.25] 1.2–1.6× as long as posteriorly broad; tergite III [1.1] 1.1–1.4× as long as posteriorly broad; tergites IV–V [1.0] 1.0–1.3× as long as posteriorly broad; ovipositor robust, [1.45] 1.3–1.5× as long as hind tibia; lower valve with slightly swelling in the base and mid region.

Coloration. Head black, mouthparts orange; antenna brownish. Mesosoma orange, with propleuron, pronotum, mesoscutum, basal half of the scutellum and mesopleuron, except posterior margin black. Metasoma orange with tergites V+ black. Anterior and mid leg entirely orange, hind leg entirely 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, with its base and apex pallid and sheath dark brown.

Male. Unknown.

Variation. Some specimens have hind leg with proximal half of the femur brownish.

Distribution. Brazil, Colombia **, Ecuador ** and Peru ( Fig 106 ).

Biological notes. Host unknown.

Etymology. The specific name refers to the similarity with A. franklini Gauld, 1991 .

Comments. Acrotaphus homeofranklini sp. n. closely resembles A. franklini mainly by having parts of the mesosoma black, but differs from it by having the margin of the gena 0.3–0.5× length of eye in dorsal view and posterior ocelli separated from eyes by 0.2–0.3× its diameter in dorsal view (margin of the gena 0.6–0.75× length of eye in dorsal view and posterior ocelli separated from eyes by 0.4–0.7× its diameter in dorsal view, in A. franklini ).
