( Figs. 2 A, 3B, 4C, 5D, 6B, 6F, 7C). Diagnosis. Atractodes propodeator can be distinguished from all other species of the species-group by the combination of the following characters: antenna with 19 flagellomeres, central flagellomeres thicker than the distal ones, the seventh one 1.7–2.0 × as long as broad, width of penultimate 0.86–0.9 × the width of first flagellomere ( Fig. 4 C); ventral part of gena and ventral part of mesopleuron with relatively short and sparse setae ( Figs 3 B, 6B); metasoma, except the black tergite I, entirely red-orange ( Fig. 7 C); basal half of antenna bright yellow, the rest dark brown ( Fig. 5 D). Body length: 9.6–11.1 mm . Description. Female : Body length 9.6–11.1 mm . Fore wing length 6.6–7.5 mm . Head . Transverse, about 0.6 × as wide as long, not narrowed behind compound eyes, rounded (viewed from above); gena 0.5–0.6 × as long as eye, smooth and shiny with dense shallow setiferous punctures, setae relatively short, not 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 1.4–1.7 × 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 glabrous. Malar space about 0.9 × basal mandibular width, strongly granulate. Antenna with 19 flagellomeres; first flagellomere, seventh and penultimate 3.5–4.4, 1.7–2.0 and 1.3–1.4 × as long as wide, respectively; antenna slightly widened at mid part, width of penultimate 0.86–0.9 × the width of first flagellomere. FIGURE 7. Metasoma of A. propodeator species-group, dorsal view: A— A. verapacensis (holotype); B– A. reijoi (paratype ♀); C— A. propodeator (paratype ♀). Mesosoma ( Figs 2 A, 3B, 6B, 6F). Pronotum strongly and densely punctate in the anterior lateral part, longitudinally strigose in the anterior submarginal depression and in the posterior ventral part; dorsal posterior corner with shallow punctures; epomia strong but short, only reaching the anterior submarginal depression. Mesoscutum fine and densely punctate on a smooth and shiny background, only central lobe slightly granulate anteriorly; notauli deep, reaching about 0.6–0.7 × the length of mesoscutum; prescutellar groove deep, with longitudinal striae; scutellum with sparse fine and shallow setiferous punctures, vertically strigose at apex; lateral carina present, reaching 0.7–0.8 × its length. Mesopleuron shiny, with moderately strong and sparse setiferous punctures; central part smooth and glabrous, ventral part with relatively short setae; sternaulus deep, reaching 0.8 × the length of mesopleuron, in anterior part transversally strigose, posteriorly widely rugose, shiny. Metapleuron strongly rugose and densely setose; juxtacoxal carina absent; propodeum mostly strongly rugose, shiny, setae long and sparse; median area strongly strigose transversally, conspicuously broader in the central part, about 1.5–1.9 × as long as its maximum width, flat; spiracle relatively big, slightly ovoid, separated from pleural carina 1.8–1.9 × its diameter. Legs long and slender; length of hind femur 4.2–4.5 × its width; hind tarsal claws thin and rightangled curved, clearly longer than arolium. Wings . Densely setose. Fore wing with pterostigma about 2.9–3.3 × wider than high, vein Rs +2 r about 1.8 × longer than its height; areolet pentagonal, open, about 0.9–1.0 × higher than wide; 2 m-cu with a single bulla; first abscissa of Cu 1a 1.3–1.6 × Cu 1b. Hind wing with vein cu-a + abscissa of Cu 1 between M and cu-a angulate, intercepted at its lower 0.2–0.3, slightly reclivous; distal abscissa of Cu 1 distinctly pigmented. Metasoma ( Fig. 7 C). Tergite I very finely granulate, with few short lateral setae and fine longitudinal wrinkles, 2.7–3.0 × longer than posteriorly broad; in lateral view, dorsal part strongly curved; cross section of petiole rectangular, upper side flat; tergite II very finely granulate, about 1.5–1.8 × longer than basally broad; lateral crease separating tergite II from epipleuron, absent; other tergites smooth and shiny, glabrous. Colouration ( Figs 5 D, 7C). Body black; mandible teeth orange; basal half of antenna bright yellow, the remainder dark brown. Legs red-brown. Metasoma from tergite II to the apex, red-orange, lighter at the apex; tergite I black. Male: unknown. Etymology. The specific name refers to the characteristic propodeum of the species. Type material. Holotype 1 ♀: Brazil , Nova Teutonia, Santa Catarina, October 1970 , Fritz Plaumann ( AEIC ). Paratype : Brazil , same locality and collector, 23.V.1948 , 1 ♀ ( AEIC ).
