Diller (2004): A new Aethecerus species from Spain (Insecta, Hy-menoptera, Ichneumonidae, Alomyini). -Spixiana 27/1: 61-65 Aethecerus tatoi, spec. nov. is described from the South of Spain. The differences to the most closely related species, Aethecerus subniger (Berthoumieu, 1904), are discussed.

Introduction The genus Aethecerus Wesmael, [1845] belongs to the tribe Alomyini (sensu Wahl & Mason 1995) and to the subtribe Phaeogenina (sensu Diller 1981, Selfa & Diller 1994). Aethecerus is characterized by: Oral carina strongly raised and excavated behind the base of the mandible; gena excavated; apex of clypeus strongly impressed, above the Impression with a more or less distinct ridge which is strongly im-pressed or absent centrally; clypeus separated from the supraclypeal area by a sharp groove. Aethecerus Wesmael is represented in the Palae-arctic region with 24 species and 1 subspecies, in the Nearctic region with 2 species (Yu & HorstmaiTn 1997, Sebald et al. 2000). Material and Methods The material was obtained from the G. Heinrich collec-tion (iabeled as "Mus. Zooi. Polonicum Warszawa, 6/46, ex. col. G. Heinrich") kcpt in the Instytut Zoologiczny (Warszawa, Poland) (IZW). It was collected by Andre Seyrig in southern Spain at two localities of the Province of Ciudad Real (Fucncaliente and Puertollano) during the years 1924 (1 ex.), 1926 (1 ex.), and 1927 (the remain-ing 45 ex, including the holotype). The entomological coliections of Zoologische Staatssammlung München (ZSM), Munich, Germany and the Laboratori d'Entomo-logia del Departament de Zoologia de la Universität de Valencia (LEUV), Valencia, Spain, contain 6 and 5 para-types, respectively. The new species has been compared with the lecto-type of Aethecerus subniger (Berthoumieu, 1904), desig-nation and combination by Diller (Diller & Horstmann 1994). The REM pictures were obtained with the technique established by Selfa & Schönitzer (1994). Aethecerus tatoi, spec. nov. Figs 1-3 Types.
