Hymenoepimecis kleini Pádua & Sobczak sp. n.

( Figs 43–46 )

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) face 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 opening pocket-like structure reduced longitudinally; 6) sternite I with a ventral projection, spine-like, posteriorly; 7) female with tarsal claw with flat preapical tooth, apex of claw overtaking 3.0 × the tooth; 8) female with ovipositor 1.3–1.4 × as long as hind tibia.

Description. Female. Body [8.0] 7.0–10.0 mm; face [0.85] 0.85–0.9 × 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] × 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 [0.8] 0.7–0.8 × 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 [5.9] 5.2–7.7 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 [4.0] 3.9–5.0 mm; abscissa of Cu 1 meeting cu-a equidistant between 1 A and M. Hind leg with tibia + tarsus [0.61] × the fore wing length; tarsal claw with a flat preapical tooth, apex of claw overtaking [3.0] 3.0-3.5 × the lobe. Metasoma slender; tergite I [1.75] 1.6–1.75 × as long as posteriorly broad, with lateral carinae only present at extreme anterior end flanking the anterior concavity; sternite I with a ventral projection, spine-like, posteriorly; tergite II [1.28] 1.28–1.4 × as long as posteriorly broad; tergites III–IV [1.3] 1.2–1.3 × as long as posteriorly broad; ovipositor [1.3] 1.3–1.4 × 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– III, tergite IV with half black, tergite V black with orange lateral mark on anterior margin; ovipositor dark brown with base and apex slightly brownish, sheath dark brown.

Male. Unknown.

Variation. Hind margin of tergites II–IV laterally black marked.

Distribution. Brazil (Amazonas) (Fig. 47).

Biological notes. Host unknown.

Etymology. This species is named after Bert Klein, in order to acknowledge his great sampling effort in the reserves of PDBFF (INPA), Amazonas State, Brazil.

Type material. Holotype ♀. BRAZIL, Amazonas: Manaus, Reserva 1208, Fazenda Esteio, PDBFF, 02°22’34’’S / 59°52’39’’W, 03.xii.1985, Malaise (B. Klein), INPA. Paratype Amazonas: Manaus, Reserva 1208, Fazenda Esteio, PDBFF, 02°22’34’’S / 59°52’39’’W, 06.viii.1985, Malaise (B. Klein), 1 female, INPA. Total: 2 females.

Comments. Hymenoepimecis kleini sp. n. closely resembles H. jordanensis , H. uberensis sp. n. and H. amazonensis sp. n., mainly by having the face sculptured below the insertion of antennae, longitudinal carina in the middle part of the face and with few bristles spaced on the lower face, by sternite I with a ventral projection, spinelike, posteriorly. It differs from the first by having weak black lateral marks on posterior margins of tergites II–IV. It differs from the second mainly by the hyaline wings, orange hind leg with apex of femur, tibia and tarsus dark brown. It differs from the third mainly by having the tarsal claw with a flat preapical tooth, apex of claw overtaking 3.0 × the lobe.
