( Figs 4 A, 4D, 5A–B, 6A, 6C–D, 7A) Diagnosis. Female of A. verapacensis can be distinguished from all other species of the A. propodeator speciesgroup by the combination of the following characters: antenna entirely dark brown, with 20–21 flagellomeres, seventh flagellomere 2.6–2.7 × as long as broad; additionally, both female and male, have ventral part of gena and ventral part of mesopleuron with dense long silvery setae ( Fig. 6 A), and metasoma reddish from tergite II. Body length: 5.7–7.2 mm . Description. Female : Body length 5.7–7.2 mm . Front wing length 4.5–5.7 mm . Head . Transverse, about 0.6 × as wide as long, not narrowed behind compound eyes, rounded (viewed from above); gena about 0.5 × as long as eye, smooth and shiny with very dense shallow setiferous punctures, setae relatively long, denser at ventral part. 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 1.2–1.3 × its own maximum diameter; distance between posterior ocelli 0.7–0.8 × its own maximum diameter. Face finely and very densely punctate on a granulate background. Clypeus weakly convex, 2.2–2.3 × 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 about 0.8 × the length of upper tooth. Eye with very short sparse setae. Malar space about 0.8–0.9 × basal mandibular width, strongly granulate. Antenna with 20–21 flagellomeres; first flagellomere, seventh and penultimate 4.2–4.7, 2.6–2.8 and 1.9– 2.0 × as long as wide, respectively; antenna slightly widened at mid part or filiform, width of penultimate 0.9–1.0 × the width of first flagellomere ( Fig. 4 A).

FIGURE 3. Morphology of female meospleuron: A— Atractodes species-group A; B— A. propodeator species-group; C— A. altoandinus species-group; D— Atractodes species-group B. Mesosoma ( Figs 6 A, 6C). Pronotum sparsely punctate in the anterior lateral part, longitudinally strigose in the posterior ventral part; dorsal posterior corner with shallow punctures; epomia strong in the upper part, then very shallow and shortly extended parallel to the anterior margin of pronotum. Mesoscutum fine and densely punctate on a smooth and shiny background; notauli deep, reaching about 0.4–0.5 × the length of mesoscutum; prescutellar groove deep, smooth, with longitudinal striae; scutellum without lateral carina, with dense fine and shallow setiferous punctures, apically with vertical wrinkles. Mesopleuron shiny, with moderately strong and dense setiferous punctures, central part smooth and glabrous, setae long; sternaulus deep, reaching about 0.75 × the width of mesopleuron, not strigose or rugose. Metapleuron strongly rugose and very densely setose; juxtacoxal carina absent. Propodeum with a short dorsal face and a flat posterior face sloped abruptly downwards; posterior part of area basalis strongly elevated, almost reaching the level of postescutellum, forming a deep concavity at base, strigate longitudinally; propodeum mostly strongly rugose, more or less shiny, setae long and dense; median area strongly strigose transversally, broad in the central part, about 1.6–2.4 × as long as its maximum width, flat; spiracle small, rounded, separated from pleural carina 2.7–3.6 × its diameter. Legs long and slender; length of hind femur 4.3–5.0 × its width; hind tarsal claws thin and forming an obtuse angle, clearly longer than arolium. Wings . Densely setose. Fore wing with pterostigma about 3.0–3.3 × wider than high, vein Rs +2 r about 1.6–2.1 × longer than its height; areolet pentagonal, open, about 0.8–0.9 × higher than wide; 2 m-cu with a single bulla; first abscissa of Cu 1a 1.6–1.8 × Cu 1b. Hind wing with vein cu-a + abscissa of Cu 1 between M and cu-a, angulate, intercepted at its lower 0.3, slightly reclivous; distal abscissa of Cu 1 distinctly pigmented. Metasoma ( Figs 5 A, 7A). Tergite I smooth, with few short lateral setae and few longitudinal wrinkles, 3.0–3.3 × longer than posteriorly broad; in lateral view dorsal part strongly curved; cross section of petiole at the mid part hexagonal, upper side flat; tergite II smooth and shiny, about 1.5 × longer than basally broad; lateral crease separating tergite II from epipleuron, present at basal third; other tergites smooth and shiny, with only very few sparse setae. Colouration ( Fig. 5 A). Body black; mandible teeth and base of antenna dark brown. Legs orange to light brown. Metasoma from tergite II to the apex, reddish; tergite I black. Male : Body length 7.2 mm . Front wing 5.7 mm . Head . Clypeus about 2.4 × as wide as long. Malar space about 0.7 × basal mandibular width. Antenna with 24 flagellomeres; first flagellomere, seventh and penultimate 3.4, 2.7 and 2.0 × as long as wide, respectively; tyloids absent; flagellum evenly tapered to the apex ( Figs 4 D, 5B), width of penultimate about 0.6 × the width of first flagellomere.

Mesosoma . Prescutellar groove somewhat deep, smooth, without longitudinal striae. Propodeum with median area about 1.8 × as long as its maximum width, flat ( Fig. 6 D). Metasoma . Slender and elongate, seen from side apically acute, seen from above slightly depressed. Tergite I very finely granulate, postpetiolus somewhat smooth, with few long lateral setae and few longitudinal wrinkles, 3.6 × longer than posteriorly broad, dorsal part strongly curved in lateral view, lateromedian and lateral longitudinal carinae strong, reaching postpetiolus ( Fig. 6 D), ventral longitudinal carina complete; tergite II polished, about 2.2– 2.3 × longer than basally broad; other tergites smooth and shiny, with sparse setae, denser at apex. Colouration ( Fig. 5 B). Metasoma with tergites II–IV reddish, apex dark brown; tergite I brownish. Other features as in female. Etymology.
