Spalangia Latreille, 1805

Spalangia Latreille, 1805: 227–228 . Type species: Spalangia nigra Latreille , by monotypy.

Prospalangia Brèthes, 1915: 314 . Type species: Prospalangia platensis Brèthes , by original designation.

Diagnosis. Head, pronotal collar and/or mesonotum usually with some setiferous punctures or crenulae (e.g. Figs 1–7), but if not then mostly smooth and shiny with short, sparse setae (e.g. Figs 374–378). Head with occipital carina (e.g. Figs 4, 116), at least dorsally, except for noyesi -group species (Fig. 375); lower face often acutely angled under torulus so in lateral view torulus appears to be at apex of short tube extending beyond level of base of mandible (e.g. Figs 22, 286, 367). Maxillary and labial palpi 2-segmented (Fig. 116, insert). Wings fully developed, bare or variably densely setose behind submarginal vein but usually obviously less setose than disc (e.g. Figs 9, 191–194). Mesopleuron with variably sculptured subalar scrobe, episternal scrobe/line and precoxal scrobe/line differentiating upper and lower mesepimeron from upper mesepisternum posterior to acropleuron and pectal region (e.g. Fig. 6); pectal region with at least 1 seta posteroventrally; upper and lower mesepisternum usually differentiated by transepisternal line and/or variable number of setae in line anterior to mesocoxa (e.g. Figs 34, 44, 54). Propodeum with paramedian crenulate furrows (e.g. Fig. 7) except smooth and shiny in noyesi -group species (Fig. 381). Petiole much longer than wide, longitudinally carinate-strigose to reticulate-rugose, and with acutely pointed anterolateral angles directed anteriorly so as to form W- like depression for posterolateral margins of propodeal foramen (e.g. Figs 71, 89, 201, 355). Gaster with tergites strongly sclerotized, often flattened but not collapsed in air dried specimens, and with comparatively inconspicuous, sparse setae dorsally (Figs 121, 229, 230); Gt 1 deeply, uniformly concave anteriorly with depressed region carinately margined laterally (e.g. Figs 121, 229, 230), and Gt 3 usually conspicuously larger than Gt 2 and Gt 4.
