Acrotaphus cuzconus Pádua & Sääksjärvi  sp. n.

( Figs 48–51View FIGURES 48–52)

Diagnosis. This species can be distinguished from all other species of Acrotaphus  by the combination of the following characters: 1) fore wing blackish with one yellowish band extending backwards from anterior margin, just proximal to the pterostigma to the encounter of cu-a to base of the Rs&M; 2) metasoma entirely reddish orange; 3) female tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe; 4) posterior ocelli separated from eyes by 0.1× its diameter in dorsal view.

Description. Female. Body [13.0] mm. Head. Lower face [0.8]× 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 [0.5]× length of eye in dorsal view; posterior ocelli separated from eyes by [0.1]× its diameter in dorsal view. Mesosoma. Pronotum moderately long, smooth and polished, with distance from tegula to head greater than [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 ventrally; epicnemial carina present ventrally, extending until reaching the level of the lower corner of the pronotum laterally; metapleuron polished, with fine bristles evenly spaced; propodeum smooth dorsally, laterally with scattered fine bristles. Fore wing [11.5] mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.8]× 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 [1.3]× 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]× as long as posteriorly broad; tergite II [1.5]× as long as posteriorly broad; tergite III [1.45]× as long as posteriorly broad; tergites IV–V [1.3]× as long as posteriorly broad; ovipositor slender, [1.5]× as long as hind tibia; lower valve with slightly swelling in the base and mid region.

Coloration. Head black, except apical margin of clypeus slightly yellowish, mouthparts yellowish, except apex of mandible black; antenna dark brown. Mesosoma and metasoma entirely reddish orange. Anterior leg orange and mid and hind legs entirely black. Fore wing blackish with one yellowish band extending backwards from anterior margin, just proximal to the pterostigma to the encounter of cu-a to base of the Rs&M; hind wing black with apex yellowish; pterostigma yellowish. Ovipositor brownish.

Male. Unknown.

Distribution. Peru ( Fig 52View FIGURES 48–52).

Biological notes. Host unknown.

Etymology. The specific name refers to Cuzco, Peru.

Comments. Acrotaphus cuzconus  sp. n. closely resembles A. monotaenius  sp. n. mainly by having fore wing blackish with one yellowish band extending backwards from anterior margin, just proximal to the pterostigma to the encounter of cu-a to base of the Rs&M, and differs from it mainly by having tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe, mid leg entirely black and metasoma entirely reddish orange (tarsal claw with basal lobe longitudinally elongated, with claw apex clearly overtaking the posterior margin of lobe, mid leg entirely orange and metasoma entirely black, in A. monotaenius  sp. n.).
