description: Atractodes pleuripunctatus sp. nov.
(Figs 1 B, 2A, 2D, 3B, 4B, 4E)
Diagnosis. Atractodes pleuripunctatus can be distinguished from all other species of the A. pleuripunctatus species-group by the combination of the following characters: median area of propodeum strongly punctate (Fig. 2 D); postpetiole long, rectangular; hind femur 6.7 × longer than deep; tarsal claws with relatively broad base, moderately long and abruptly curved at distal 0.4 (Fig. 4 E); fore and mid coxa light orange, posterior coxa brown (Fig. 1 B); flagellum with conspicuous white long linear sensillae (Fig. 4 B).
Description. Female: Body length 5.1–5.9 mm. Fore wing length 4.3–4.5 mm.
Head (Figs 3 B, 4B). Transverse, about 0.5–0.6 × as wide as long, narrowed behind compound eyes, straight (viewed from above); gena about 0.5 × as long as eye, smooth and shiny with very sparse shallow setiferous punctures, setae relatively short. Frons and vertex smooth and shiny with shallow setiferous punctures, setae relatively short. Occipital carina rounded in middle part. Posterior ocellus separated from eye by 1.5 × its own maximum diameter; distance between posterior ocelli 0.5–0.6 × its own maximum diameter. Face finely and very densely punctate on a granulate background. Clypeus weakly convex, 2.0 × as wide as long, densely punctate on a smooth and shiny background, apex slightly upturned medially, setae conspicuously longer than in face. Lower tooth of mandible 0.7–0.8 × the length of upper tooth. Eye with very short sparse setae. Malar space about 1.1–1.2 × basal mandibular width, conspicuously granulate behind the mandible base, vanishing towards compound eye. Antenna with 17 flagellomeres; first flagellomere, seventh and penultimate 5.9, 3.7–3.9 and 1.6–1.7 × as long as wide, respectively; antenna slightly widened towards apex, width of penultimate 1.6–1.7 × the width of first flagellomere (Fig. 3 B); flagellum with conspicuous white long linear sensillae (Fig. 4 B).
Mesosoma (Figs 2 A, 2D, 4E). Pronotum finely and densely punctate, stronger and denser in the anterior lateral part; epomia shallow and short, only reaching the anterior submarginal depression. Mesoscutum fine and densely punctate on a smooth and shiny background; notauli shallow and short, reaching about 0.1–0.2 × the length of mesoscutum; prescutellar groove deep, smooth, with longitudinal striae; scutellum with dense fine and shallow setiferous punctures, not delimited by a lateral carina. Mesopleuron shiny, with fine and dense setiferous punctures; sternaulus deep, almost reaching the hind rim of mesopleuron (Fig. 2 A). Metapleuron strongly punctate and granulate; juxtacoxal carina absent. Propodeum more or less convex and uniformly sloped downwards posteriorly (Fig. 2 A); mostly strongly granulate, setae long and dense; area basalis not well defined; longitudinal carinae shallow and irregular, median area slightly defined, strongly granulate, more or less broader in the central part, about 2.5–3.5 × as long as its maximum width (Fig. 2 D); spiracle small, rounded, separated from pleural carina 1.8–2.0 × its diameter. Legs long and slender; length of hind femur about 6.7 × its width; tarsal claws with relatively broad base, moderately long and abruptly curved at distal 0.4, clearly longer than arolium (Fig. 4 E).
Wings. Very densely setose. Fore wing with pterostigma about 2.4–2.6 × wider than high, vein Rs +2 r about 1.0–1.1 × longer than its height; areolet pentagonal, open, about 0.7–0.8 × higher than wide; 2 m-cu with one or two close bullae; first abscissa of Cu 1a 1.1–1.5 × Cu 1b. Hind wing with cu-a angulated, intercepted at its lower 0.3, slightly reclivous; distal abscissa of Cu 1 not pigmented.
Metasoma. Tergite I finely granulate, with few long lateral setae, 4.3–4.5 × longer than posteriorly broad, in lateral view dorsal part strongly curved; cross section of petiole on the mid part circular, upper side slightly convex; postpetiole long, rectangular; tergite II polished, finely granulate only on basal third, about 2.9–3.1 × longer than basally broad; lateral crease separating tergite II from epipleuron more or less present at basal third; other tergites smooth and shiny, with only very few sparse setae.
Colouration (Fig. 1 B). Black to dark brown; apex of postannellus and mandibles somewhat lighter. Legs brown; fore and mid coxae, trochanters and trochantelli, light orange. Metasoma from tergite II to the apex, reddish; tergite I black.
Male: unknown.
Etymology. The specific name refers to the strongly punctate sculpture of the mesopleuron.
Type material. Holotype 1 ♀: Ecuador, Pimo, Cañar, 3200 m, 10–12.XII.1970, leg. Luis Peña (AEIC). Paratype: Same data, 1 ♀ (AEIC).
