SUBTRIBE PHYGADEUONTINA 

 Genus OECOTELMA Townes 



Oecotelma Townes, 1970 (1969). Amer. Ent. Inst., Mem. 12: 94. 



Type-species: Hentiteles cushmaiti Butcher. Monotypic and orig. desig. 

 cushmani (Butcher). Mich. Host: Gyrinus sp.

Genus SULCARIUS Townes 



Sulcaritis Townes, 1970 (1969). Amer. Ent. Inst., Mem. 12: 95. 



Type-species: Hemiteles kellbachi Schmiedeknecht. Orig. desig. 



Species of this genus apparently parasitize larvae of caddisflies whose cases are left exposed 

 by the receding waters of vernal ponds or intermittent streams. 



biannulatus (Gravenhorst). Minn.?, 111.?; Europe. Host: Limnephilus iJidivisus Walker. North 

 American specimens were identified as biannulatus by Roman (1925) and Mickel and 

 Milliron (1939), but the question of conspecificity of Neartic and Paleartic specimens has 

 apparently not been readdressed; therefore, the occurrence of biannulatus in North 

 America remains unsubstantiated.
