description: Atractodes saragurensis sp. nov.
(Figs 1 C, 2B, 2E, 3C, 4C, 4F)
Diagnosis. Atractodes saragurensis can be distinguished from all other species of the A. pleuripunctatus speciesgroup by the combination of the following characters: median area of propodeum strongly punctate (Fig. 2 E); postpetiole long, rectangular (Fig. 2 E); hind femur 6.7 -7.7 × longer than deep; tarsal claws with a thin base, very narrow and long, apically as if stretched, evenly curved (Fig. 4 F); all coxae brown (Fig. 1 C); sensillae of flagellum more or less conspicuously apparent (Fig. 4 C).
Description. Female: Body length 5.7 mm. Fore wing length 4.5–4.8 mm.
Head (Figs 3 C, 4C). Transverse, about 0.6–0.7 × as wide as long, slightly narrowed behind compound eyes, rounded (viewed from above); gena about 0.6 × as long as eye, smooth and shiny with sparse setiferous punctures, setae relatively short. Frons and vertex mostly smooth and shiny with dense shallow setiferous punctures, frons rugose behind the antennal sockets, setae relatively short. Occipital carina rounded in middle part. Posterior ocellus separated from eye by 1.7–1.8 × its own maximum diameter; distance between posterior ocelli 0.6 × its own maximum diameter. Face finely and very densely punctate on a smooth and shiny background. Clypeus weakly convex, 2.2 × 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 0.6 × the length of upper tooth. Eye with relatively long 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 4.8–5.2, 2.9 and 2.1 × as long as wide, respectively; antenna slightly widened towards apex, width of penultimate about 1.3 × the width of first flagellomere (Figs 3 C); whitish sensillae of flagellum more or less conspicuously apparent (Fig. 4 C).
Mesosoma (Figs 2 B, 2E, 4F). Pronotum finely and densely punctate, slightly 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 0.3 × the length of mesoscutum; prescutellar groove deep, smooth, without 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 B). Metapleuron strongly punctate and granulate; juxtacoxal carina absent. Propodeum mostly strongly punctate and granulate, setae long and dense; area basalis not well defined; longitudinal carinae shallow and irregular, median area slightly defined, strongly punctate, about 2.1–3.0 × as long as its maximum width (Fig. 2 E); spiracle small, rounded, separated from pleural carina 2.4–3.4 × its diameter. Legs long and slender; length of hind femur about 6.7–7.7 × its width. Hind tarsal claws with thin base, very narrow and long, apically as if stretched, evenly curved (Fig. 4 F).
Wings. Very densely setose. Fore wing with pterostigma long, about 2.6–3.0 × wider than high, vein Rs +2 r about 1.4–1.6 × longer than its height; areolet pentagonal, open, about 0.8 × higher than wide; 2 m-cu with one bullae; first abscissa of Cu 1a 1.3–1.5 × Cu 1b. Hind wing with cu-a angulated, intercepted at its lower 0.2–0.3, straight; distal abscissa of Cu 1 not pigmented.
Metasoma (Figs 1 C, 2E). Tergite I with setiferous punctures on a shiny background, 4.3–4.8 × longer than posteriorly broad, in lateral view dorsal part strongly curved (Fig. 1 C); cross section of petiole on the mid part circular, upper side slightly convex; postpetiole long, rectangular (Fig. 2 E); tergite II polished, about 2.7–3.1 × longer than basally broad; lateral crease separating tergite II from epipleuron present at basal third or less; other tergites smooth and shiny, with sparse setae.
Colouration (Fig. 1 C). Black to dark brown. Legs dark brown. Metasoma from tergite II to the apex, reddish; tergite I black.
Male: unknown.
Etymology. The name of the species refers to Saraguro, locality where the holotype was collected. Saraguro is a village in the Ecuadorian province of Loja and is inhabited by the indigenous ethnic group Saraguros, belonging to the Kichwa indigenous nationality of the Ecuadorian Sierra.
