PTEROMALIDAE OF N.W. EUROPE 819 



Schizonotus sieboldi Ratzeburg 



Pteromalus (Schizonotus) Sieboldi Ratzeburg, 1852 : 230, $, [<£]. 

 Schizonotus sieboldi Ratzeburg ; Boucek, 1958a : 395-397, fig. 1, <$ $. 

 Pteromalus (Schizonotus) sieboldi Ratzeburg ; Boucek, 1964& : 672. 



Type material. Types presumed lost. Boucek (1958a : 395-397) discussed the 

 identity of sieboldi and concluded that it was a valid species, basing his conclusions 

 on the host mentioned by Ratzeburg and the latter's mention of the colour of the 

 antennae in one of his specimens, which could only have been a male of the present 

 species. Later (1964& : 672) he found, in a remnant of Ratzeburg's collection in 

 Eberswalde, a female which could be one of the original specimens ; it agreed with 

 his earlier definition. 



Germany, Czechoslovakia, U.S.S.R. 



Biology. Chief host Melasoma popidi (L.) (Col., Chrysomelidae) ; see Boucek, 

 1958a. 



KRANOPHORUS Graham 



Pteromalus sgen. Coelopisthus Thomson, 1878 : 162 [emendation of Coelopisthia Forster, 1856]. 



Coelopisthia Nikol'skaya, 1952 : 220, ex parte [nee Forster, 1856]. 



Kranophorus Graham, 1956b : 257. Type-species : Pteromalus extentus Walker, 1835, by 



original designation. 

 Coelopisthia Peck, 1963 : 665-667 [nee Forster, 1856]. 

 Kranophorus Graham ; Peck et al., 1964 : 50. 



It seems quite certain that Coelopisthus Thomson was intended as an emendation 

 of Coelopisthia Forster, from Thomson's reference in his Swedish footnote (1878 : 

 162) ; it was also regarded as such by Gahan & Fagan (1923 : 38). Now Ashmead 

 (1904 : 320, 371) designated Pteromalus cephalotes Walker [1836] as type-species of 

 Coelopisthia Forster, which had originally been described without included species. 

 Unfortunately the lectotype of Pteromalus cephalotes Walker is a female identical 

 with Pteromalus puparum (L.) ; hence Coelopisthia falls as a synonym of Pteromalus 

 Swederus (q.v.). The species included in Coelopisthus by Thomson as " Pteromalus 

 cephalotes Walker " was in fact erroneously identified on the basis of false informa- 

 tion supplied by Reinhard ; it has nothing to do with Walker's cephalotes but is the 

 same as extentus Walker. For this reason I redescribed (1956&) the genus 

 Coelopisthia of authors {nee Forster) as Kranophorus. Peck would prefer to preserve 

 the customary usage of the name Coelopisthia and suggested (1963 : 665) that the 

 International Commission should be asked to reject Ashmead's designation of 

 Pteromalus cephalotes Walker as type-species and to replace it by that of Coelopisthia 

 cephalotes Thomson [= C. extentus (Walker)].
