Type material. Holotype ♀, Vipio fiebrigi Brethes , 1909, Paraguay : San Bernardino (no date) (Fiebrig) (MACN). Additional specimens examined. Argentina : 1 ♀, Chaco, Las Brecias (no date, collector) (USNM); 1 ♀, Chaco, Montevidio So. Amer. Paras lab, No. 674.20, v.1942 (Berry) (USNM); 1 ♂, Chaco, Colonia Benintez, 10.xii.1948 (R. Golbach) (IFML); 3 ♂, Tucuman, Araoz , Estacion, 8.i.1927 (no collector) (IFML). Diagnosis. This species can be distinguished from other Neotropical species with very long ovipositors (> 2.0 x body length) by having a yellow-red head, densely striate metasoma and a pointed basal lobe to the claw. Description. Holotype♀, length of body 8.5-12.3 mm, of fore wing 6.5-9.0 mm, and of ovipositor (part exserted beyond apex of abdomen) 21.5-30.0 mm. Head. Antenna robust, 0.94-0.97 x body length, with 62-68 flagellomeres; remaining 0.92-1.0 x longer than wide; first flagellomere 1.4 x longer than second; first flagellomere 2.7 x longer than wide; second flagellomere 1.4 x longer than wide; median flagellomeres 1 x longer than wide; terminal flagellomere (missing); head transverse to sub-transverse; clypeus higher in profile, slightly rugulose, clypeal guard setae typical; face sparsely punctate or rugulose; remainder of head smooth and shiny; HL 0.79-0.84 x HH; HW/HH 0.79-0.84; FH/FW 0.42-0.45; EH/HH 0.62-0.64; EH/FW 0.75-0.78; EW/EH 0.7-0.75; ITD 1.5-1.65 x TOD; MS 0.42-0.46 x EH; LMC 0.4 x HH; third segment of maxillary palp 4 x wider than long. Mesosoma. Length of mesosoma 1.70-1.81 x height; pronotum smooth and shiny or transversely carinate dorso-laterally, smooth and shiny or crenulate at furrow dorso-laterally; notauli smooth, mesonotal lobes well defined; metapleuron smooth to slightly punctate; propodeum strongly reticulate or areolate-rugose postero-medially, smooth or punctate on basal and lateral margins. Wings. Fore wing: length of fore wing/body length 0.72-0.76; PL/LRC 0.89-0.94; PW/PL 0.21-0.28; length of vein 3RSb 0.82-0.87 x combined length of r-rs and 3RSa; length of vein 1M 0.78-0.80 x length of (RS+M)a; vein 3RSa reaching wing margin 0.52-0.59 x distance between apex of pterostigma and wing tip. Hind wing: with basal glabrous area and/or with sparse basal setosity (Fig. 7E ); apex of vein C+SC+R with one basal hamule. Legs. Claw with strong pointed basal lobe. Metasoma. First metasomal tergite 1.32-1.34 x longer than wide, rectangular, slightly narrowing anteriorly; raised median area oval, areolate-rugose; basal smooth area narrowing and continuing posteriorly as median longitudinal carina reaching small smooth raised area at the apex of tergum; surrounding area with short transverse carinae; dorso-lateral carina present, area below crenulate; T II 1.15-1.25 x wider than medially long, depressed, baso-lateral areas sub-triangular, smooth and shiny, mediobasal area smooth and shiny, continuing posteriorly as median longitudinal carina, remainder of tergum longitudinally striate, oblique furrow strongly impressed, striate; T III 1.4 x wider than medially long, longitudinally striate, baso-lateral area well defined; T IV longitudinally striate, baso-lateral area short and transverse; T V-VII smooth and shiny; hypopygium extending 0.4-1.0 mm beyond apex of metasoma, ovipositor 2.2-2.6 x body length. Colour. Yellow to reddish yellow, except tip of mandible, labial palp, basal two segments of maxillary palp, labio-maxillary complex, antenna basally, fore trochanter, middle and hind legs and ovipositor sheath black. slightly smoky to dark brown, pterostigma black, yellow basally. Male . Unknown. Remarks. Based on the long body, ovipositor length, similar propodeal and metasomal sculpture, this species is closely related to V. melanocephalus Brulle . The longer MS (0.42-0.46 x EH) and yellow head in fiebrigi will separate it from melanocephalus , in which the MS/EH ratio is 0.39-0.41 and the head is black. Figure 7.
