Genus DOLOPHRON Foerster 



Dolophron Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 155. 



Type-species: Limneria pedella Holmgren. Monotypically included and desig. by 

 Townes, 1970. 



Townes (1970) said that this is a Holarctic genus including pedella and two undescribed spe- 

 cies, one North American and one Japanese. D. pedella is the only species known to me; I have 

 in the past identified as Dolophron a few Nearctic specimens which were sent to me for identifi- 

 cation, but now regard those specimens as representing an unidentifled species of Synetaeris. 



pedella (Holmgren). Europe. Introduced in N. H. in 1931 without becoming established. Host: 

 Heterarthrus nemoratus (Fall.). According to Dowden (1941) only 12 mated females 

 were released in the attempt to establish pedella in N. H. on H. nemoratus.

Genus SYNETAERIS Foerster 



Synetaeris Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 155. 



Type-species: Synetaeris heteropus Thomson. Desig. by Viereck, 1914 from three 

 species included by Thomson, 1887. 



This is a smaU genus; it is known to me from the Holarctic and Ethiopian Regions. There are a 

 number of unidentified or undescribed Nearctic species, some of which will probably prove to be 

 Holarctic species that have already been described from Europe or Asia. 



hyalina (Provancher), n. comb. Que. 



Limneria hyalina Provancher, 1874. Nat. Canad. 6: 147. 9 {6 misdet.). Townes (1945) and 

 Barron (1975) have applied this name to Campoplex crassatus (Viereck), contrary to the 

 valid lectotype selection of Gahan and Rohwer (1918). Barron's rejection of the Gahan 

 and Rohwer lectotype because of what he regarded as lack of agreement with the 

 original description has no validity. Because Provancher stated that he had two females 

 and one male, lack of agreement with the original description does not prove that the 

 Gahan and Rohwer lectotype was not one of Provancher^s syntypes. Gahan and Rohwer 

 (1918) evidently thought the specimen agreed sufficiently weU with the description to 

 have been a syntype, and their lectotype selection stands as valid unless evidence of 

 some other sort is found to prove that the specimen they selected was not a syntype.
