 Biolysia Schmiedeknecht, 1907. Hym. Mitteleuropas, p. 601. 



Type-species: Nepiesta marginella Thomson. Monotypic. 



This is a Holarctic genus of moderate size. Horstmann (1973, 1974) treated Biolysia as distinct 

 from Bathyplectes to facilitate an easier distinction of the Palearctic genus Nepiesta. Because 

 the species referable to Biolysia do not differ significantly in habits or life histories from other 

 Bathyplectes species and because Bathyplectes bryanti Viereck is structurally intermediate, I 

 prefer to treat Bathyplectes and Biolysia as synonymous. Known hosts include only weevils oi 

 the genus Hypera, but the majority of Bathyplectes species have not been reared. The native 

 Nearctic species are poorly represented in collections, and the majority of them are undescribed.

 anurus contractus (Thomson). Central Calif.; s.w. U. S. S. R., Iran, s. Yugoslovia?, s. Germany, 

 n. Italy, n. France, Ireland. Introduced. Host: Hypera brunneipennis Boh. Besides a. 

 contractus and a. anurus (Thomson), Horstmann (1974) recognized a. graecator Aubert 

 (treated here below); he knew a. anurus from southern Sweden (lectotype), The 

 Netherlands, and northern and middle Germany. I am not convinced that these 

 subspecies will be treated as valid taxa when more specimens have been collected and 

 studied, but I here accept them as valid because my knowledge of western Palearctic 

 zoogeography is not adequate for rejecting them for reasons of being insufficiently 

 sound zoogeographically. Dr. Richard Dysart informed me (personal commun., 1977) of 

 the establishment in Calif, of a population he thought most likely to be principally of 

 Iranian origin. For that reason I have applied the name a. contractus to it.

 anurus graecator Aubert. Southern N. H., s. Vt., Mass., Conn., N. Y., N. J., Pa., Del., Md., Va.,

 Yugoslavia, Greece, middle and s. Italy, s. France, n. Africa. Introduced. Host: Hypera 

 postica (Gyll.). According to Dysart and Day (1976) the bulk of the anurus individuals 

 released in eastern North America were of "French [apparently southern] origin," 

 although small numbers came from Sicily and the U. S. S. R.
