Superfamily ICHNEUMONOIDEA 695 



Phradis Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 148. 



Type-species: Thersilochus (Phradis) hrevis Brischke. By subsequent monotypy 

 from inclusion by Brischke, 1880. 

 Eutomus Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 148. 



Type-species: Isurgus lanceolatus Szepligeti. Monotypically included and desig. by 

 Viereck, 1914. 

 Isurgus Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 148. 



Type-species: Isurgus lanceolatus Szepligeti. Desig. by Viereck, 1914 from nine 

 species included by Szepligeti, 1899. 



This is a Holarctic genus of moderate size. Horstmann (1971) treated 11 European species, and 

 Townes (1971) said he had seen five Nearctic species, all of which he believed to be undescribed.

Genus DIAPARSIS Foerster 



Ischnobatis Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 148. 



Type-species: Thersilochus (Ichnobatis[.']) stramineipes Brischke. By subsequent 

 monotypy from inclusion by Brischke, 1880. 

 Diaparsis Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 149. 



Type-species: Porizon nutritor Gravenhorst. Desig. by Perkins, 1962 from 12 

 species included by Thomson, 1889. The type-species is Gravenhorst's 

 misidentification of Ophion nutritor Fabricius. According to Horstmann (1971) 

 nutritor in the sense of Gravenhorst is a synonym of Diaparsis truncata 

 (Gravenhorst).

Type-species: Luchatema baldufi Walkley. Monotypic and orig. desig. 



According to Townes (1971) this is a large genus of Holarctic, Oriental, and Ethiopian distribu- 

 tion. Horstmann (1971) treated seven European species. Two European species which are 

 parasites of Oulema melanopus (L.) have been released in North America; one of these, D. 

 carinifer (Thomson), has not become established; the other, a new species soon to be described 

 by Dr. Klaus Horstmann, is established or at least has been recovered in w. N. Y., Pa., w. W. Va., 

 Ohio, s. Mich., and n. Ind. according to unpublished information supplied by T. L. Burger.

 carinifer (Thomson). Europe. Introduced in Michigan in 1967 and a number of times since, 

 without becoming established. Stehr and Haynes (1972) reported the species as 

 established, but the record of establishment applies not to carinifer but to Diasparsis n. 

 sp. (see above introductory paragraph on Diaparsis).

 published by Laboulbene (1889) indicates that fascicle 13 of Opusc. Ent. was published 

 prior to June 12, 1889.
