Hymenoepimecis duckensis Pádua & Onody sp. n.

( Figs 32–36 )

Diagnosis. This species can be distinguished from all other Hymenoepimecis by the combination of the following characters: 1) fore wing hyaline yellowish, with two blackish bands; 2) pronotum predominantly black; 3) female with tarsal claw narrow elongated vertically, with apex slightly overtaking the lobe; 4) female with ovipositor 1.5– 1.6 × as long as hind tibia.

Description. Female. Body [12.3] 11.0–14.0 mm; face [0.95] 0.95–1.0 × as broad as high (from supraclypeal suture to base of antenna), smooth, slightly convex with few spaced bristles; head in dorsal view with genae strongly narrowed behind eyes; posterior ocelli separated from eyes by about [1.0] 0.9–1.0 × its own maximum diameter; occipital carina projected and curved upwards dorsally. Pronotum long, smooth and polished, with distance from tegula to head is greater than [0.64] 0.6–0.7 × distance from tegula to hind margin of propodeum with an anteriorly, and 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, 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 [10.4] 9.8–11.8 mm; cu-a interstitial to the base of Rs&M; 1 m-cu with a stump in the middle; 2 rs-m [0.4] 0.4–0.7 × as long as abscissa of M between 2 rs-m and 2 mcu; abscissa of Cu 1 meet 1 m-cu close to Cu 1 b that Cu 1 a; hind wing with [7.0] 6.5–8.6 mm and abscissa of Cu 1 meeting cu-a equidistante between M and 1 A. Hind leg with tibia + tarsus [0.6] 0.5–0.6 × the fore wing length; tarsal claw narrow elongated vertically, with apex slightly overtaking the lobe. Metasoma slender; tergite I [1.3] 1.3–1.4 × as long as posteriorly broad, centrally quite strongly convex with lateral carinae only present at extreme anterior end flanking the anterior concavity; sternite I with a low, rounded swelling posteriorly; tergite II [1.0] 1.0– 1.1 × as long as posteriorly broad; tergites III–IV [0.88] 0.88–1.1 × as long as posteriorly broad; ovipositor [1.5] 1.5–1.6 × as long as hind tibia.

Coloration. Head black; clypeus with yellowish apex; mouthparts yellowish, with apex mandible black; antenna black with brownish apex. Mesosoma orange, with pronotum and propleuron blacks. Anterior and median leg orange, the hind black with base of coxa orange. Fore wing hyaline yellowish, with apex distal to 2 rs-m blackish, and with a blackish median band extending backwards from anterior margin, just veins Rs+M and junction of pterostigma with vein R 1; pterostigma black, hind wing with slightly blackish band in median part. Metasoma orange, with tergites VI+ black; ovipositor black with base and apex brownish and sheath black.

Male. ( Fig. 33 ). Similar to female in structure and coloration, but with tarsal claw simple; body with 8.6–11.0 mm; fore wing with 8.6– 7.1 mm. Genital capsule ( Fig. 71–73 ): Paramere rounded apically, narrower than the parameral lamina parameral, with bristles in apicodorsal margin; parameral lamina covered by dense bristles, except in posterior margin; volsellar lamina with bristles spaced, except in posterior region; cuspis with tooth in apical part; digitus about 0.4 × the length of cuspis + volsellar lamina, with tooth in apex, rounded apically and angulated basally, as wide as the basal region; aedeagus (including aedeagal apodeme) about 1.0 × the length of paramere + parameral lamina (including parameral apodeme).

Variation. Only male with black half part in the pronotum.

Distribution. Brazil (Amazonas, Pará, Rondônia) (Fig. 37).

Biological notes. Host unknown.

Etymology. The specific name refers to type locality of this species, Reserva Ducke in Amazonas State, Brazil.

Comments. Hymenoepimecis duckensis sp. n. closely resembles H. neotropica , mainly by having the fore wing hyaline yellowish with two blackish bands, metasoma with tergites VI+ and hind legs blacks, the sternite I with a low, rounded swelling posteriorly. It differs from it by not having tarsal claw with preapical tooth.
