reclassification of microgasterini 181 



The LONGIPALPIS-Grovp 

 Monobasic. 



Apanteles longipalpis Reinhard 



Apanteles longipalpis Reinhard, 1880 : 365, [in key only]. 

 Apanteles longipalpis Reinhard, 1881 : 44, [description]. 



Nothing really separates this species from the laevigatus-gvoup except the form of 

 the mouth parts. I have given it group-status merely to emphasise this feature, 

 since similar modifications have been used elsewhere in this work to throw into relief 

 any deviation from the normal structural patterns found within Apanteles. 



$. Except for the base of the tibia, the hind legs are black almost throughout. Wings milky- 

 white but the venation distal to the apex of the 1st abscissa of the medius pigmented ; stigma 

 brown. 



Head from in front (Text-fig. 122). Flagellum thin, thread-like, shorter than body with 

 segment 16 about twice as long as wide. 



Mesoscutum highly polished except for minute setiferous punctures. 



There is some variation in the shape of the 1st tergite, some specimens showing it less elongate, 

 some more, than in Text-fig. 121. Ovipositor sheath about one and a half times longer than the 

 hind tibia. 



Length: ca. 4 mm. without ovipositor. 



o*. One of the few species of Apanteles in which the male can be recognised ; the palpi are 

 exactly as in the female. 



Europe. In England, this species has been swept in numbers by R. L. E. Ford 

 from Achillea (Compositae). 



An unmistakeable species on account of the extraordinary mouth parts. 



The LAEVIGATUS-Grovp 



Group U, Wilkinson, in part. 



This group contains the majority of those solitary European species with long 

 ovipositor and propodeum without either areola or medial keel and includes laevigatus 

 (Ratzeburg). 19 Certain species such as dilectus Haliday (Wilkinson, 1945) which 

 Wilkinson included in his group U are probably better placed in my «/for-group. 

 Replacements of this kind will be dealt with at a later date. 



The edge of the vannal lobe is always more or less evenly convex and fringed 

 throughout with minute hairs though these tend to be absent in the common Euro- 

 pean sicarius Marshall (Wilkinson, 1945). 



The ACICULATUS-Grovp 

 Monobasic. 



Apanteles aciculatus (Ashmead) 



Urogaster aciculatus Ashmead, 1900 : 289. 



Pseudapanteles sancti-vincenti Ashmead, 1900 : 291 [Synonymy Muesebeck, 1908 : 431]. 



Apanteles thoracicus Muesebeck, 1920 : 534 [n. n. for Pseudapanteles sanctivincenti Ashmead, 



1900 : 291 nee Apanteles sanctivincenti Ashmead, 1900 : 279]. 



19 Microgaster laevigatus Ratzeburg, 1848 : 50.
