Diagnosis. This species can be distinguished from all other Hymenoepimecis by the combination of the following characters: 1) hyaline wing; 2) metasoma orange, with posterior margins of tergites II–V narrowly black, tergites VI+ black; 3) sculptured below the insertion of antennae, with longitudinal carina in the middle part; 4) occipital carina projected, not curved upwards, with a concavity in the apex dorsally; 5) pronotum with pocket-like structure reduced longitudinally; 6) sternite I with a ventral projection, spine-like, posteriorly; 7) tarsal claw with short basal lobe vertically, slightly quadrangular with apex of claw clearly overtaking the lobe; 8) ovipositor 1.3–1.4 × as long as hind tibia.
Description. Female. Body [6.6] 6.4–6.9 mm; face [0.85] 0.9–0.95 × 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 [1.0] 0.9–1.0 × its own maximum diameter; occipital carina projected, not curved upwards, with a concavity in the apex dorsally. Pronotum long, smooth and polished, with distance from tegula to head is greater than [0.58] 0.58–0.7 × 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 [4.6] 4.6–4.9 mm; cu-a interstitial to the base of Rs&M; 2 rs-m [0.2] × as long as abscissa of M between 2 rs-m and 2 m-cu; hind wing with 3.2–3.3 mm; abscissa of Cu 1 meet cu-a equidistante between 1 A and M. Hind leg with tibia + tarsus [0.52] 0.5–0.6 × the fore wing length; tarsal claw with short basal lobe vertically, slightly quadrangular with apex of claw clearly overtaking the lobe. Metasoma slender; tergite I [1.88] 1.7–1.9 × 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 ventral projection, spine-like, posteriorly; tergite II [1.33] 1.3–1.4 × as long as posteriorly broad; tergites III–IV [1.15] 1.15–1.4 × as long as posteriorly broad; ovipositor [1.26] 1.26–1.4 × as long as hind tibia.
Coloration. Head black, area of the inserts of the antennae pale; clypeus yellowish, with base slightly black; mouthparts yellowish, with apex mandible black; antenna brown blackish. Mesosoma orange. Anterior and median leg orange, the hind leg orange, with apex of femur, tibia and tarsus brown blackish. Wings hyaline; pterostigma brown. Metasoma orange, with tergites VI+, and with weak black lateral marks on posterior margins of tergites II– IV, tergite V with posterior half black; ovipositor dark brown with base and apex slightly brownish, sheath dark brown.
Male. Unknown.
Distribution. Brazil (Amazonas) (Fig. 26).
Biological notes. Host unknown.
Etymology. The specific name refers to type locality of this species, Amazonas State, Brazil.
Type material. Holotype ♀. BRAZIL, Amazonas: Manaus, Reserva Ducke, Igarapé Bolívia, 10.ii.2003, Malaise (J.M.F. Ribeiro), INPA. Paratype: Amazonas: idem, but Igarapé Uberé, vi.2003 (J.M.F. Ribeiro & J. Vidal), 1 female; idem, but Igarapé Ipiranga, v.2003, Malaise (J.M.F. Ribeiro), MZUSP. Total: 3 females.
Comments. Hymenoepimecis amazonensis sp. n. closely resembles H. jordanensis Loffredo & Penteado-Dias, 2009, H. uberensis sp. n. and H. kleini sp. n. mainly by 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. It differs from the first by presence of weak black lateral marks on posterior margins of tergites II–IV and by ovipositor being 1.3–1.4 × as long as hind tibia. It differs from the second mainly by the hyaline wings hind leg orange with apex of femur, tibia and tarsus dark brown. It differs from the third mainly by having the tarsal claw with short basal lobe vertically, slightly quadrangular with apex of claw clearly vertaking the lobe.
