Itamoplex Foerster, 1868. Naturh. Ver. Rheinlande, Verb. 25: 188. 



Type-species: Cnjptns aniericanua Cresson. Desig. by Viereck, 1914 from three 

 species included by Ashmead, 1900. 

 • Plesiocryptiis Cameron, 1903. Ztschr. f. System. Hym. Dipt. 3: 299. 

 Type-species: Plesiocryptus carinifrous Cameron. Monotypic. 



This large genus is Holarctic, Oriental, and Ethiopian. The controversy regarding the name 

 Cryptiis remains unsettled. Even if Opinion 135 (see Hemming, 1939) were valid, Crypfus 

 Fabricius (1804) would still be preoccupied by Cryptus Panzer (1804) (a subjective synonym of 

 Arge), and Eucryptus Haldeman may be a valid replacement name for Cryptus Fabricius. 

 Henniiing's (1945) conclusion that "suspension [of the Rules] would not be essential in the case 

 of Cryptus Panzer [1804]" is incorrect because Panzer's fascicle 88 (1804) of Fauna Insectorum 

 Germanicae is shown to predate Fabricius's Systema Piezatorum by virtue of the fact that the 

 former is cited on page 35 of the latter. Cryptus is used here because I feel that it is virtually 

 certain that the majority of specialists presently studying Ichneumonidae would choose to sup- 

 press Cryptus Jurine (1801), Cryptus Panzer (1804), and Eucryptus Haldeman (if the latter is 

 valid).
