New species of Prototilla Schuster, 1949 from Argentina and diagnoses of the genus based on male and female (Hymenoptera: Bradynobaenidae: Typhoctinae: Eotillini) Author Torréns, Javier Author Fidalgo, Patricio Author Roig-Alsina, Arturo Author Brothers, Denis J. text Zootaxa 2012 3427 17 32 journal article 10.5281/zenodo.215056 9518f767-ef4a-4879-a21d-72b3f5f8233a 1175-5326 215056 Prototilla anomala Schuster, 1949 (Figs 1–3, 6, 29–32) Prototilla anomala Schuster, 1949 : 71 –75. Diagnosis. Male . First and second segments of metasoma reddish, the rest black (Figs 1, 3, 29, 30). T1 and T2 with plumose setae across their surfaces, scale-like setae only on their posterior margins (Fig. 2). T1 spiracle located on a small protuberance. Fore wing moderately setose ( Figs 6 , 32 ). Female . Unknown. Description and characterization provided by Schuster (1949) . Variation. T 3 may be entirely reddish like T1 and T2 (and then T 4 may be reddish basally), or reddish only basally, rather than entirely black. Discussion. Schuster based his description on a specimen deposited in the Paris Museum (André Collection) from “ Argentina (no further data)”. In fact, the holotype bears a second label “Mendoza” ( Fig. 31 ), which narrows down the type locality. The additional specimens examined here extend the known distribution several hundred kilometers north-north-east of the type locality. While the detailed description by Schuster (1949) is correct, a few additional characters useful to differentiate this species from others are given in the diagnosis above. Although Schuster indicated the length as “ 5–6 mm ”, which would indicate that he had more than one specimen, he stated (1949: 67, footnote) that Prototilla was represented by “the unique type ” and listed only the holotype , so the length was an estimate, perhaps because the metasomal segments are somewhat telescopically extended ( Figs 29, 30 ).
