Oliveira, Marcio L. Zootaxa 2020 2020-01-09 4719 1 1 62 Padua Padua 2020 [151,518,1581,1608] Insecta Ichneumonidae Acrotaphus Animalia Hymenoptera 19 20 Arthropoda species dolichopus sp. nov.  ( Figs 53–56)   Diagnosis.This species can be distinguished from all other species of  Acrotaphusby the combination of the following characters: 1) posterior ocelli separated from eyes by 0.4–0.6× its diameter in dorsal view; 2) fore wing yellowish hyaline with two black bands; 3) tarsal claw with basal lobe longitudinally elongated, with claw apex clearly overtaking the posterior margin of lobe.   Description.Female. Body [10.6] 10.5–14.0 mm. Head.Lower face [0.9] 0.9–1.0× 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 the gena flat behind the eyes; margin of gena [0.4]× length of eye in dorsal view; posterior ocelli separated from eyes by [0.4] 0.4–0.6× its diameter in dorsal view. Mesosoma.Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.5] 0.5–0.6× 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 [9.5] 9.5–11.0 mm; cu-aopposite to the base of Rs&M; 2 rs-m[0.6] 0.6–0.7× as long as abscissa of Mbetween 2 rs-mand 2 m-cu; hind wing with abscissa of Cu1 between Mand cu-a[0.8] 0.8–1.3× length of cu-a. Tarsal claw with basal lobe longitudinally elongated, with claw apex clearly overtaking the posterior margin of lobe. Metasoma.Tergite I [1.5] 1.3–1.6× as long as posteriorly broad; tergite II [1.1] 1.1–1.5× as long as posteriorly broad; tergite III [1.0] 1.0–1.3× as long as posteriorly broad; tergites IV–V [0.85] 0.85–1.2× as long as posteriorly broad; ovipositor slender, [1.6] 1.5–1.8× as long as hind tibia; lower valve with slightly swelling in the base and mid region.   FIGURES 53–57.  Acrotaphus dolichopus  sp. n., ♀ (holotype): 53, habitus; 54, head, dorsal view; 55, face, frontal view; 56, tarsal claw, scale bar =0.2 mm. 57. Distribution of  Acrotaphus dolichopus  sp. n.in the Neotropical region.  Coloration.Head black, except apical margin of clypeus slightly orange, mouthparts orange, except apex of mandible black; antenna brownish. Mesosoma entirely orange. Metasoma orange with posterior margins of tergites II–IV black and tergites VI+ black. Anterior and mid leg entirely orange, hind leg entirely black. 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 orange and sheath dark brown.  Male.Unknown.  Variation.Three females from Panama(one specimen) and French Guiana(two specimens) with pronotum black, except its apical margin; metasoma orange, with posterior margin black in the tergite IV and tergites V+ black; pronotum orange, except anterior part black; and metasoma with tergites VI+ black. We think they are conspecific, but we are not treating them as paratypes.   Type material:   Holotype: ♀, BRAZIL, SP [= São Paulo], Luiz Antônio, Est.

It differs from it mainly by having posterior ocelli separated from eyes by 0.4–0.6× its diameter in dorsal view (posterior ocelli separated from eyes by 0.2× its diameter in dorsal view, in  A. nambilloensis  sp. n.). 2545462778 2009-04-29 R, APTA Pont I Brazil -21.613056 Ecologica de Jatai 21 47.817776 21 22 1 1 Sao Paulo holotype 2545462699 2009-10-15 APTA Brazil & Pont II Brazil -21.613056 Ecologica de Jatai 21 47.817776 21 22 1 1 Sao Paulo paratype 2545462809 MV French Guiana 227 4.568917 Km 1 -52.185833 Roura on Kaw Rd. 21 22 227 2545462698 [248,947,549,576] 2007-04-16 2007-04-17 2007-04-16 FSCA D.
