STUROVIA Boucek 



Sturovia Boucek, 1961 : 86. Type-species : S. tenuicornis Boucek, by monotypy and original 

 designation. 



Females of the type-species of Sturovia, squamifera Thomson (=tenuicornis 

 Boucek), differ from those of all the species of Mesopolobus in the shape of the 

 head, particularly when seen in frontal view. If this character alone were 

 considered, one might regard Sturovia as a genus distinct from, though very close 

 to, Mesopolobus. However, in males of squamifera the shape of the head is more 

 like that of some Mesopolobus. Moreover, the female of albitarsus (Walker), 

 although it has essentially the same type of venation, antennae, and thorax (parti- 

 cularly the propodeum) as squamifera, has the head shaped much as in some species 

 of Mesopolobus. This bridges the gap between Sturovia and Mesopolobus. 

 Undoubtedly squamifera and albitarsus are closely allied, and share a combination of 

 characters (striate clypeus and face, venation, structure of propodeum, and 

 coloration) which mark them off as a group rather distinct from Mesopolobus. 

 Provisionally I am treating this group as a distinct genus, although it might be 

 better regarded as a species-group, or at most a subgenus, of Mesopolobus. The 

 species are included in my keys to Mesopolobus.

Eutelus (Amblymerus) squamifer Thomson, 1878 : 81. 

 Sturovia tenuicornis Boucek, 1961 : 87-88, $. 

 Sturovia squamifera (Thomson) Boucek, 19650 : 35. 



Type material. Eutelus (Amblymerus) squamifer Thomson. One female, accepted 

 as type (probably holotype), labelled " Hbg " [Halsingborg] and " squamifer Ths ". 



Sturovia tenuicornis Boucek. Holotype $, Southern Slovakia, between Kamenica 

 nad Hronom and Kovacov, near Sturovo, 19. v. i960 (Boucek), in Narodni Museum, 

 Prague (Cat. no. 2973). The species was synonymized with Eutelus squamifer 

 Thomson by Boucek (19650). 



Britain : New record, Buckinghamshire, Hell Coppice, near Oakley, 1 9, ig.viii. 

 i960 (Graham) ; Sweden, Czechoslovakia. 



Biology. This species has been reared in Czechoslovakia from twigs of oak 

 (" aus Eichenzweigen ") according to Boucek (1961 : 88) ; my British specimen was 

 swept from foliage of Quercus robur L. Imagines April-May and Aug.-Sept.
