The SCHOENOBII-Grovp 

 Monobasic. 



Apanteles schoenobii Wilkinson 



Apanteles schoenobii Wilkinson, 1932a : 142 



This is a remarkable species, quite unlike any other known to me except that it 

 bears a curious, if fortuitous, resemblance to the N. American terminalis Gahan in 

 general habitus. 



The head is deep from back to front and is dull above with a satin-like sheen and 

 an extremely fine, dense punctation. The very narrow apical margin of tergite 

 (2 + 3)-6 is transparent and membranous (Text-fig. 346). 



In the type female, the apical half of tergite (2 -f- 3) is yellow but in all other 

 females I have seen, tergite (2 + 3) is entirely blackish. The apical half of this 

 tergite, though quite differently sculptured from the basal half, is, nevertheless, 

 finely roughened. The gaster bears a very fine, very dense pubescence. The ovi- 

 positor sheath is about as long as the hind tibia. 



India to the Philippines. Type locality : S. India. 

 Type in the British Museum (Nat. Hist.). 



Host : Schoenobius bipunctiferus Walker (Schoenobiidae) ; Proceras polychrysa 

 Meyrick (Crambidae) ; Diatraea sp. (Crambidae). 



Monobasic.

Apanteles vipio Reinhard 



Apanteles vipio Reinhard, 1880 : 365. [In key only]. 

 Apanteles vipio Reinhard, 1881 : 44. [Description]. 



$. Head from in front weakly elongate. Face, and more especially the clypeus, finely, very 

 superficially punctate. Galea fully twice as long as wide ; glossa deeply forked. Scape of the 

 antenna long, about twice as long as wide (Text-figs. 117 and 118). Mesoscutum highly polished. 

 Propodeum strongly rugose, the rugae tending to radiate outwards from an irregularly defined 

 medial keel. Vannal lobe beyond its widest part weakly convex and here with a trace of 

 projecting hairs. Inner spur of the hind tibia fully three quarters as long as the hind basitarsus. 

 Tergite 1 strongly, abruptly narrowed at apex ; deeply furrowed just where it turns over. 

 Lateral, polished zone of scutellum not cutting off a parallel-sided groove. Ovipositor sheath 

 about three fifths as long as the hind tibia. Length: ca. 3-5 mm. without ovipositor. 



Central Europe. 



Host : Reinhard records the single female known to him as having been bred 

 from Tinea (now Scythris) knochella F. (Scythrididae). 



This is a most distinctive species, without close allies known to me, and character- 

 ized very largely by the extremely short metacarp.
