Acrotaphus jackiechani Pádua & Sääksjärvi sp. n.

( Figs 107–115 )

Diagnosis. This species can be distinguished from all other species of Acrotaphus by the combination of the following characters: 1) margin of gena concave (flat in male) behind eyes in dorsal view; 2) posterior ocelli separated from eyes by 0.3–0.4× its diameter in dorsal view; 3) mesosoma orange, with pronotum entirely or only its anterior margin black; 4) metasoma orange with tergites V+ black or orange with posterior margin black in the tergites II–III and tergites VI+ black; 5) hind leg entirely black, except the base of coxa orange; 6) ovipositor robust, 1.2–1.5× as long as hind tibia.

Description. Female. Body [16.0] 13.0–16.0 mm. Head. Lower face [0.95] 0.9–1.0× as broad as high (from supraclypeal suture to base of antenna), flat, with scattered punctures which bear long conspicuous bristles present laterally; head in dorsal view with margin of gena concave behind eyes; margin of gena [0.5]× length of eye in dorsal view; posterior ocelli separated from eyes by [0.3] 0.3–0.4× its diameter in dorsal view. Mesosoma. Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [0.6] 0.4–0.6× 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; propodeum smooth dorsally, laterally with scattered fine bristles. Fore wing [12.0] 10.0–12.0 mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.95] 0.7–0.95× 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 [1.8] 1.6–1.8× as long as posteriorly broad; tergite II [1.65] 1.5–1.8× as long as posteriorly broad; tergite III [1.6] 1.4–1.6× as long as posteriorly broad; tergites IV–V [1.4]× as long as posteriorly broad; ovipositor robust, [1.4] 1.3–1.4× as long as hind tibia; lower valve with slightly swelling on the base and mid region.

Coloration. Head black, mouthparts orange, except apex of mandible black; antenna brownish. Mesosoma orange, except pronotum blackish. Metasoma orange, with tergites V+ black. Anterior and mid leg entirely orange, the hind leg black, except base of the coxa orange. 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 pterostigma, right through the 1 st subdiscal cell; pterostigma yellowish. Ovipositor brownish and sheath dark brown.

Male. ( Figs 110–111 ). Similar to female in structure and coloration, except body 0.8–9.0 mm; lower face 1.0× 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 0.5–0.7× length of eye in dorsal view; posterior ocelli separated from eyes by 0.4–0.7× its diameter in dorsal view; fore wing 7.0– 0.8 mm; tergite I 1.2–1.6× as long as posteriorly broad; tergite II 1.0–1.2× as long as posteriorly broad; tergite III 1.0–1.1× as long as posteriorly broad; sternite IX ( Fig 113 ) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin and posterior margin flat, with a few bristles widely spaced posteriorly. Genital capsule ( Figs 114–115 ): Paramere truncated apically, slightly narrower than the parameral lamina, with bristles except on posterior margin; volsellar lamina with spaced bristles laterally and apically, except in the median and posterior regions and inner margin and posterior part and with a set of about four bristles in anterolateral region, just below the base of the digitus; cuspis robust with about five to six teeth more or less aligned in the mid part until apex and with some small bristles in basal region and spaced laterally in 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 with margin of gena more or less flat behind eyes and pronotum orange, with anterior margin black and metasoma orange, with posterior marks blackish on the tergites II–III. We think they are conspecific, but we are not treating them as paratypes.

Distribution. Brazil, Ecuador **, French Guiana, Nicaragua and Peru ( Fig 116 ).

Biological notes. Host unknown.

Etymology. The specific epithet, “jackiechani”, is the Latinized genitive form of the name Jackie Chan, chinese actor and director of several films, in which the first author is a fan.

Comments. Acrotaphus jackiechani sp. n. closely resembles A. latifasciatus (Cameron, 1911) mainly by coloration, but differs from A. latifasciatus by epicnemial carina present ventrally, extending until reaching the level of the lower corner of the pronotum laterally (epicnemial carina present only ventrally, not extending laterally until the level of the lower corner of pronotum, in A. latifasciatus ).
