The Afrotropical and West-Palaearctic species of Ecrizotes Förster (Hymenoptera: Pirenidae)

The Afrotropical and West-Palaearctic species of Ecrizotes Förster, 1861 (Hymenoptera: Pirenidae) are reviewed. The genera Ecrizotomorpha Mani, 1939 syn. nov. and Spathopus Ashmead, 1904 syn. nov. are treated as junior synonyms of Ecrizotes based on morphological evidence. Eighteen world species of Ecrizotes are recognized, including six described as new: E. acer Mitroiu sp. nov., E. alternativa (Xiao & Huang, 1999) comb. nov., E. anomalipes (Ashmead, 1904) comb. nov., E. brevicauda Mitroiu sp. nov., E. caudatus (Thomson, 1876), E. filicornis (Thomson, 1876), E. hofferi (Bouček, 1964) comb. nov., E. incisus Mitroiu sp. nov., E. longicauda Mitroiu sp. nov., E. longicornis (Walker, 1848), E. longus Mitroiu sp. nov., E. montanus (Huggert, 1976) comb. nov., E. monticola Förster, 1861, E. nasalis (Springate & Noyes, 1990) comb. nov., E. rovumae Mitroiu sp. nov., E. taskhiri (Mani, 1939) comb. nov., and E. tenkasiensis (Jamal Ahmad & Shafee, 1993) comb. nov. All world species, except for the three East-Palearctic ones (E. alternativa, E. taskhiri, and E. tenkasiensis), and the single Nearctic species (E. anomalipes), are diagnosed, illustrated and keyed; Ecrizotes is newly reported from the Afrotropical region and new country records are given for several European species.
