Hymenoepimecis uberensis Pádua & Onody sp. n.

( Figs 65–69 )

Diagnosis. This species can be distinguished from all other Hymenoepimecis by the combination of the following characters: 1) fore wing blackish, with yellowish hyaline band between junction of vein R 1 up to pterostigma until half vein M; 2) face sculptured below the insertion of antennae, with longitudinal carina in the middle part; 3) occipital carina projected, not curved upwards, with a concavity in the apex dorsally; 4) pronotum with opening pocket-like structure reduced longitudinally; 5) sternite I with a ventral projection, spine-like, posteriorly; 6) female with tarsal claw with basal lobe slightly quadrangular and apex of claw slightly undertaking the lobe; 7) female with ovipositor about 1.1–1.2 × as long as hind tibia.

Description. Female. Body [9.7] 7.5–11.1 mm; face [1.0] 0.9–1.0 × as broad as high (from supraclypeal suture to base of antenna), sculptured below the insertion of antennae, with longitudinal carina in the middle part and with few bristles spaced on the lower face; head in dorsal view with genae strongly narrowed behind eyes; posterior ocelli separated from eyes by [0.75] 0.75–1.0 × its own maximum diameter; occipital carina not curved upwards, with a concavity in the apex dorsally. Pronotum long, smooth and polished, with distance from tegula to head is greater than [0.6] 0.6–0.7 × distance from tegula to hind margin of propodeum with an anteriorly, and opening pocket-like structure 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, rather uniformly covered with sparse, fine setiferous punctures; propodeum smooth, polished, with sparse, fine setiferous punctures and with lateral longitudinal carina present only posteriorlly. Fore wing with [7.7] 6.6–8.4 mm; cu-a interstitial to the base of Rs&M; 2 rs-m [0.3] 0.3–0.4 × as long as abscissa of M between 2 rs-m and 2 m-cu; abscissa of Cu 1 meeting 1 m-cu equidistant between Cu 1 a and Cu 1 b; hind wing with [5.5] 4.7–8.1 mm; abscissa of Cu 1 meeting cu-a close to 1 A that M. Hind leg with tibia + tarsus [0.5] 0.5–0.6 × the fore wing length; tarsal claw with basal lobe slightly quadrangular, with apex of claw slightly overtaking the lobe. Metasoma slender; tergite I [1.1] 1.1–1.4 × as long as posteriorly broad, centrally quite strongly convex with lateral carinae only presente at extreme anterior end flanking the anterior concavity; sternite I with a ventral projection, spine-like, posteriorly; tergite II [0.95] 0.9–1.1 × as long as posteriorly broad; tergites III– IV [0.88] 0.88–1.0 × as long as posteriorly broad; ovipositor [1.16] 1.1–1.2 × as long as hind tibia.

Coloration. Head black; clypeus yellowish with black base; mouthparts yellowish, with apex mandible black; antenna brown. Mesosoma orange. Anterior and median leg orange, the hind leg black, with base of coxa orange. Fore wing blackish, with yellowish hyaline band between junction of vein R 1 up to pterostigma until half vein M; pterostigma black; hind wing blackish with base and apex slightly yellowish. Metasoma orange, tergites VI+ black; ovipositor black with base and apex brownish and sheath brown blackish.

Male. ( Fig. 66 ). Similar to female in structure and coloration, but with tarsal claw simple; body with 5.9–8.6 mm; fore wing with 4.9–7.3 mm. Genital capsule ( Figs 80–82 ): Paramere rounded apically, narrower than the parameral lamina, with bristles in apicodorsal margin; parameral lamina, with bristles spaced, mainly in dorsal region; volsellar lamina with britles in anterolateral region; cuspis with tooth in apical part; digitus about 0.5 × the length of cuspis + volsellar lamina, with tooth in apex, truncated apically and angulated basally; aedeagus (including aedeagal apodeme) 1.0 × the length of paramere + parameral lamina (including parameral apodeme).

Distribution. Brazil (Amazonas, Pará, Rondônia, Roraima) (Fig. 70).

Comments. Hymenoepimecis uberensis sp. n. closely resembles H. amazonensis sp. n., H. jordanensis and H. kleini sp. n., mainly by having the face sculptured below the insertion of antennae, with longitudinal carina in the middle part and with few bristles spaced on the lower face, by sternite I with a ventral projection, spine-like, posteriorly. However, H. uberensis sp. n. differs from them mainly by having the fore wing blackish, with yellowish hyaline band between junction of vein R 1 up to pterostigma until half vein M.
