THE GENUS CRYPTUS FABRICIUS, 1804 OF THE CANARY ISLANDS (HYMENOPTERA, ICHNEUMONIDAE) by G. VAN ROSSEM ABSTRACT Rossein, G. van, 1989. The genus.Cryptur Fabricius, 1804 of the Canary Islands (Hymenoptera, Ichneumonidae). - Tijdschrift voor Entomologie 132: 251-258, tables 1-7. [ISSN 0040-74961. Published 1 December 1989. Cryprur dzunae Gravenhorst, 1829 rofivagztr subsp. nov. is described from Tenerife. A rede- scriprion of the holotype of Cryprus obscuripes Zettersredt, 1838 is given and the species is acknowledged to be distinct. C. obscuriper impeditur subsp. nov. is described from Tenerife, Palma and Gomera. The lectotype of Cvptus nigritarrir Kriechbaumer, 1894 from Tenerife is redescribed. More specimens from Tenerife, only males, were found. Four new species are described, viz., Cryptus praefortir from Tenerife and Gomera. Cryptur uftramondanur from Lanzarote, Cryptur znsulrtrir from Fuerteventura and Cryprus furws from Gran Canaria. Keys to the Cryptus males and females from the Canary Islands are given.
