RECLASSIFICATION OF MICROGASTERINI 141 



Apanteles and I have found it elsewhere only in the S. African group of camma, the 

 Indo-oriental group of taeniaticornis and the Fijian group of trifasciatus. The 

 taeniaticornis-group has a certain affinity with annulicornis but this cannot be said of 

 camma, which is an aberrant and isolated species. 



Key to Species 

 Females 



1 Body entirely fulvous, except for a darker head ; antenna with a bright yellow band 

 covering flagellar segments 6-8; vannal lobe not at all concave beyond its widest 

 part and with distinct hair-fringe throughout ; cubitellan cell about twice as high 

 as long on the radiella ; (Text-fig. 130) ; tergite 1 longer, narrower, less abruptly nar- 

 rowed posteriorly ; legs relatively longer ; hind tarsus and apex of hind tibia less 

 contrastingly darkened ; ovipositor a little longer, thicker, more curved ; eyes larger 



annulicornis (Ashmead) 13 



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



Most distinct on account of the yellow-banded antenna of the female. The 

 antenna is slightly thickened apically with segments 14-17 more or less square in 

 outline. It is probable that A. lipomeringis Muesebeck, (1958) is related to this 

 species. 

 - At least the propodeal area and the dorsum of the gaster infuscated ; antenna 

 without a yellow band, slightly shorter than the body, not at all thickened towards 

 apex and with segments 14-17 distinctly longer than wide ; vannal lobe slightly 

 concave beyond its widest part and here without trace of a fringe ; cubitellan cell 

 much higher than long on the radiella, so short, in fact, as to be easily overlooked ; 

 tergite 1 shorter, very abruptly narrowed posteriorly, with its medial channel more 

 sharply defined and extending almost onto the posterior, horizontal surface ; legs of 

 a clearer yellow colour than in annulicornis with the hind tarsus and the apex of the 

 hind tibia more contrastingly darkened ; ovipositor slightly shorter and thinner, 

 less curved ; eyes smaller ...... ruficollis (Cameron) 14 



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



Host: Recorded by Cameron as having been bred from the Pyralid, Zinckenia 

 (now Hymenia) fascialis Stoll. 



The material in the British Museum (Nat. Hist.) is represented by 4 $9 ar >d 4 6*6 , > 

 mounted together on one card ; hence, possibly a gregarious parasite. The species 

 is most distinct on account of the slit-like cubitellan cell. The male is entirely 

 brown and in both sexes the stigma is almost colourless. The stigma is entirely 

 dark in annulicornis and the ocelli are slightly larger and closer together than in 

 ruficollis. 



Wilkinson (1930:154) incorrectly synonymised brunneus Ashmead under annuli- 

 cornis. A. brunneus has the cubitellan cell of the hind wing considerably wider 

 than high and thus lacks the salient feature of the annulicornis-group. It is closely 

 related to nerion of the «m'ow-group but since the type (in British Museum (Nat. 

 Hist.)) is a male, there is nothing at this stage that I can more usefully say about it.
