with specimens (including the holotype) of A. indica (type-species of Anavoria) 

 from India, and with specimens of A. munroi Curran (type-species of Afrovoria) 

 from eastern and southern Africa, has shown no differences that can be considered 

 generic (or even specific) and it is concluded that Afrovoria and Anavoria must be 

 sunk as synonyms of Hystricovoria. This supports the synonymy of Afrovoria 

 with Hystricovoria recently established by Mesnil (1974 : 1257). The principal 

 characteristics that differentiate Hystricovoria are evident from the accompanying 

 generic key. 



The comparison of specimens from different regions just referred to, whose prime 

 object was to determine generic synonymy, showed also that there were no obvious 

 differences to be found at the specific level on external characteristics, and the male 

 genitalia were therefore examined to determine whether the nominal species involved 

 (bakeri Townsend, munroi Curran and indica Mesnil) belonged to a single widespread 

 species. The male genitalia proved to be identical in specimens available from 

 Botswana, Kenya, India (specimen from same rearing as indica holotype) and 

 the Philippines, and the names munroi and indica are therefore here sunk as new 

 synonyms of bakeri. It is evident that (like Voria ruralis) Hystricovoria bakeri 

 has a very wide distribution throughout the Old World tropics and subtropics, 

 and it is likely that the range includes Western Australia as well as the areas already 

 mentioned (the undetermined species of Hystricovoria listed by Crosskey (19736 : 128) 

 is almost certainly bakeri but is not identified positively because male specimens 

 have not been available for appropriate examination). 



H. bakeri shows some variability in the setulae at the base of vein Cu 1 and in the 

 number of sternopleural setae. The holotype of bakeri has two small setulae at 

 the base of Cu x on both wings, but the majority of specimens have this vein totally 

 bare. Intermediates occur, and specimens have been seen from India with one 

 Cu 1 setula on each wing, and from the Philippines (type-locality of bakeri) without 

 such setula on one wing but with a setula on the other, or with two setulae on one 

 wing and one on the other. The presence or absence of setulae (maximum number 

 apparently two) at the base of Cu x is clearly intraspecifically variable. Likewise, 

 the holotype of bakeri has two stpi setae, but many specimens have three, and often 

 there are two on one side and three on the other. 



Whilst discussing Hystricovoria (syn. Afrovoria) it should be pointed out that 

 the supposed differences between munroi and indica cited by d'Aguilar (1957 : 263) 

 have not been substantiated in the present work. The holotype of indica (in 

 BMNH, examined) and the other specimens standing with it from the same reared 

 series do not conform to the features that d'Aguilar mentions for indica, but run 

 in his key to munroi. It seems that 'indica' sensu d'Aguilar must be a different 

 species from indica Mesnil (= bakeri Townsend); if so I have not seen it, and it is 

 presumably undescribed. 



Lastly it is necessary to discuss the identity of Voria edentata Baranov in relation 

 to other Old World Voria species. The male holotype of edentata is apparently 

 lost (see Sabrosky & Crosskey, 1969 : 53) but conspecific specimens from the type- 

 locality (Formosa), identified by Baranov, are present in the DEI collection, one 

 male of which is accompanied by a slide preparation of its genitalia made by Baranov
