PLATECRIZOTES Ferriere 



Platecrizotes Ferriere, 1934 : 90-92. Type-species : P. sudanensis Ferriere, by monotypy. 

 Platecrizotes Ferriere ; Boucek, 1963 : 503-505. 

 Platecrizotes Ferriere ; Boucek, 1964a : 261. 



This genus was originally described in Pireninae, but Boucek (1963 : 503) 

 considered that it might be rather closely allied to Pachycrepoideus Ashmead. The 

 type-species is from Africa (Anglo-Egyptian Sudan), but recently Boucek discovered 

 a new species in Europe. 



Platecrizotes europaeus Boucek 



Platecrizotes europaeus Boucek, 1964a : 262-263, $. 



Type material. Holotype $, Moldavian S.S.R. , Vadu-lui-Vody, 29.viii.1963 

 {Boucek) in Narodni Museum, Prague (Cat. no. 25768). 



Poland, Moldavian S.S.R. 



Biology. Reared in Poland from puparia of a Dipterous genus near Drosophila 

 Fin., hidden in leaves of rosette-galls of the Cecidomyiid Rhabdophaga rosaria (Lw.) 

 on Salix purpurea L. (see Boucek, 1964a : 263). 



CRATOMINAE 



This subfamily, as defined in the present work, includes only one genus, Cratomus 

 Dalman, which is easily recognized by its characteristic head (Text-fig. 47) having 

 crests on the face and frons, in combination with the structure of the antennae. The 

 latter have the formula 11083 ; between the pedicellus and the clava there are 8 

 segments none of which is truly anelliform. 



Forster (1956 : 51) included Cratomus (=Caratomus) in his family Miscogastroidae. 

 Thomson (1876a : 217) formed for it a subtribe Caratomides of his tribe Pteromalina. 

 Ashmead (1904 : 327-332) regarded Cratomus and Paracaratomus as forming a 

 tribe within the subfamily Sphegigasterinae of Pteromalidae. Peck {in Muesebeck 

 et at., 1951 : 541 ; and 1963 : 622) follows Ashmead, but (rightly) excludes 

 Paracaratomus from Cratomini. 



The structure of the head, together with that of the antennae, seems to make the 

 group distinct enough to be regarded as a subfamily. Amongst European 

 Pteromalinae, the nearest approach to Cratomus seems to be Kaleva corynocera 

 Grah., which resembles it in many features of its thorax and gaster ; it differs 

 considerably, however, in the form of its head, antennae, and wings. Possibly the 

 resemblances do not indicate a real affinity between these two genera. 



Paracaratomus Ashmead (1894& : 335), according to the characters of its 

 type-species P. cephalotes Ashmead, is not a Cratomine. It belongs to Miscogaster- 

 inae, probably to the tribe Sphegigasterini as defined in the present work. It differs 

 from Cratomus in lacking crests on the head, and in having 2 anelli in the antennae, 

 whilst the gastral petiole is much more elongate than in Cratomus, the fore wing
