la. Theronia atalantae gestator (Thunberg), new status 



Ichneumon gestator Thunberg, 1822, Mem. Acad. Imp. Sci. St. P6tersbourg, vol. 8, 

 p. 262; 9. Type: 9, "in Indiis" (Uppsala). Redescription of type: 

 Roman, 1912, Zool. Bidr. Uppsala, vol. 1, p. 257. 



Theronia japonica Ashmead, 1906, Proc. U. S. Nat. Mus., vol. 30, p. 181, 9 • 

 New synonymy. Type: 9 , Sapporo, Japan (Washington). 



This subspecies is not particularly distinct in that some European 

 specimens and rare Nearctic specimens approach it, or are similar in 

 the amount of dark coloration. The Japanese and Korean populations 

 are rather uniform, however, in having extensive dark brown markings 

 and most individual specimens can be distinguished on this basis from 

 the great majority of European and American specimens. The 

 flagellum is reddish brown. 



Thunberg's type of Ichneumon gestator is labeled "Ind. Or." and the 

 species has always been considered an Oriental one, though a second 

 specimen has never been reported. We studied the type in 1958 and 

 found it to represent the Japanese subspecies of Theronia atalantae, 

 which is known only in Japan and Korea. 



Specimens: 3d", 179 from Japan and Korea. 



lb. Theronia atalantae atalantae (Poda) 



Ichneumon atalantae Poda, 1761, Insecta musei graecensis, p. 106. Type: Europe 



(location unknown). 

 There are also numerous synonyms of this subspecies. 



Coloration variable, paler specimens resembling the subspecies 

 fulvescens and darker specimens the subspecies japonica. The 

 majority are intermediate but closer to fulvescens. The flagellum is 

 brownish fulvous. 



Specimens: 6d\ 49 from Belgium and Germany. 



This subspecies occurs in Europe.
