Key to Oriental Subgenera of CARCELIA Robineau-Desvoidy 



i Mid tibia without a submedian v seta. Humeral callus with the three main setae 

 standing in line or almost so. Intermediate abdominal tergites without discal 

 setae .............. 2 



- Mid tibia with a submedian v seta. Humeral callus with the three main setae either 



standing in line or in a definite triangle. Intermediate abdominal tergites with 



or without discal setae ........... 4 



2 Hind coxa bare on the posterodorsal surface ....... 3 



- Hind coxa with one or more long fine setulae on the posterodorsal surface 



subgenus CARCELIELLA Baranov 



3 Four post dc setae* ...... subgenus SENOMETOPIA Macquart 



- Three post dc setae ...... subgenus CATACARCELIA Townsend 



4 Hind coxa bare on the posterodorsal surface. Mid tibia with several strong ad setae. 



Genal region wider than usual, distance between lowermost point of the eye and 

 the peristomal margin subequal to width of third antennal segment. Humeral 

 callus with the three main setae standing in a triangle . subgenus CARCELINA Mesnil 

 [The single species comprising this subgenus has more the facies of a winthemiine, 

 especially in head profile, than of Carcelia. The humeral setae also resemble 

 those of Winthemiini; the barette is, however, bare except for a single minute 

 hair at the anterior end.] 



- Hind coxa with one or more long fine setulae on the posterodorsal surface. Mid tibia 



almost always with only one (submedian) ad seta, rarely with one additional ad 

 seta basad of the main one. Genal region very reduced, obviously narrower than 

 third antennal segment. Humeral setae in line or in a triangle .... 5 



5 Intermediate abdominal tergites with strong erect discal setae among the hairing. 



Humeral callus with the three main setae usually standing in a definite triangle. 

 Scutellum with very strong lateral setae that are as large as the basal setae; 

 apical scutellar setae sometimes directed upwards; distance between insertions 

 of the subapical setae about subequal to that between a subapical seta and its 

 corresponding basal seta . . . subgenus EURYCLEA Robineau-Desvoidy 



- Intermediate abdominal tergites without discal setae, though hairing may be rather 



strong and erect. Humeral callus with the three main setae standing in line or 

 almost so, at most the middle seta only slightly forwards of a line between the 

 other two. Scutellum with lateral setae weaker than the basal setae; apical 

 scutellar setae always horizontal ; subapical setae inserted very wide apart, distance 

 between their bases conspicuously greater than that between a subapical seta 

 and its corresponding basal seta (Text-fig. 78) subgenus CARCELIA Robineau-Desvoidy 



Tribe ANACAMPTOMYIINI 



It is rare for Tachinidae to parasitize aculeate Hymenoptera and this small 

 palaeotropical group is unusual biologically in that its member species are parasites 

 in the nests of solitary and social Vespoidea; in the Oriental Region the hosts are 

 known to include species of Eumenes, Vespa and Ropalidia, but other vespid genera 

 are probably attacked. The characters of the group conform very closely to those of 

 the Carceliini, and it is mainly on the grounds of the unusual host-relations that, fol- 

 lowing Townsend (19366; 1940), tribal status is accorded to the group (Crosskey, 19736). 

 Two genera are known in the Oriental Region, Euvespivora and Koralliomyia; 

 the latter genus was placed by its describer (Mesnil, 1950a) in the Sturmiini, 



* Except only three in holotype of Carcelia (Senometopia) nitidapex Mesnil.
