Diagnosis.

This species can be distinguished from all other Hymenoepimecis by the combination of the following characters: 1) head, in dorsal view, with gena short and slightly convex behind eyes; 2) posterior ocelli separated from eyes by 0.7-0.8 times its own maximum diameter; 3) occipital carina only slightly projected and not curved upwards dorsally; 4) ovipositor 1.1-1.2 times as long as hind tibia; 5) metasoma darkish brown, with whitish lateral marks on anterior margins of tergites II-V.

Description.

Female. Body approx. [8.0] 7.0-8.5 mm; face [0.8] times as broad as high, smooth, slightly convex with few spaced bristles laterally; head in dorsal view, with gena short and slightly convex behind eyes; posterior ocelli separated from eyes by approx. [0.7] 0.7-0.8 times its own maximum diameter; occipital carina little projected and not curved upwards dorsally. Pronotum more or less long, smooth and polished, with distance from tegula to head greater than [0.5] 0.5-0.6 times distance from tegula to hind margin of propodeum, and in anterior part with opening pocket-like structure not reduced longitudinally; mesoscutum smooth and polished; scutellum, in profile, convex; mesopleuron smooth and polished, with anterodorsal and posterodorsal parts bearing sparse, fine setiferous punctures; metapleuron smooth and polished, with few sparse, fine setiferous punctures; propodeum smooth, polished, with sparse, fine setiferous punctures and with lateral longitudinal carina present only posteriorly. Fore wing approx. [6.0] 6.0-7.0 mm; cu-a more or less interstitial to the base of Rs&M; 2rs-m approx. [0.3] 0.3-0.5 times as long as abscissa of M between 2rs-m and 2m-cu; hind wing with abscissa of Cu1 meet cu-a equidistant between 1A and M. Hind leg with tibia + tarsus [0.6] times fore wing length; tarsal claw with more or less square basal lobe with apex of claw slightly overtaking the lobe. Metasoma slender; tergite I [1.7] 1.6-1.7 times as long as posteriorly width, centrally quite strongly convex with lateral carinae present only at extreme anterior end flanking the anterior concavity; sternite I with a low, rounded swelling posteriorly; tergite II approx. [1.4] 1.3-1.4 times as long as posteriorly width; tergites III and IV approx. [1.2] 1.2-1.3 times as long as posteriorly width; ovipositor [1.1] 1.1-1.2 times as long as hind tibia.

Colour. Head black with apical margin of clypeus and mouthparts (except apex mandible black) yellowish; antenna blackish. Mesosoma orange. Fore and mid leg orange, the hind leg black. Wings hyaline slightly darkish; pterostigma brownish. Metasoma darkish brown, with whitish lateral marks on anterior margins of tergites II-V; ovipositor brownish with base and apex whitish, sheath blackish.

Male.

(Fig. 97 View Figures 97–102 ). Similar to female in structure and colouration, but with body with 6.0-8.0 mm; face approx.1.1 times as width as high; posterior ocelli separated from eyes by 0.7-0.9 times its own maximum diameter. Fore wing 4.5-6.5 mm. Tarsal claw simple. Metasoma slender; tergite I 1.6 times as long as posteriorly width; tergite II approx.1.4 times as long as posteriorly width; tergites III and IV 1.2-1.3 times as long as posteriorly width.

Distribution.

Peru (Andes) (Fig. 107 View Figures 107–112 ).

Type material.

Holotype ♀. Peru, Cusco, San Pedro, 13°02'58"S, 71°32'13"W, 1500 m., 20.ix.2007, Malaise trap (C. Castillo leg.), MUSM.

Comments.

Hymenoepimecis andina sp. nov. closely resembles H. tedfordi Gauld, 1991 and Hymenoepimecis castilloi sp. nov., mainly by having hyaline fore wing and darkish metasoma. It differs from both by having metasoma with whitish lateral marks on anterior margins of tergites II-V and propodeum orange (metasoma without whitish marks and propodeum black in other two species).
