SIMULIIDAE OF AFRICA n 5 



The subgenus Simulium s. str. is probably divisible into a number of species- 

 groups distinguishable by the number of pupal gill filaments, form of the cocoon, 

 scutal pattern, presence or absence of a small basal tooth in the female claw and 

 other characters, and Rubzov (1959-1964) in fact recognizes eight species-groups in 

 the Palaearctic fauna. Only one (or possibly two) species of Simulium s. str. occur 

 in Africa (Morocco and Algeria) , and a consideration of species groupings within the 

 subgenus is outside the scope of the present paper : it is hoped at some future time 

 to review the Oriental Simuliidae, amongst which the subgenus Simulium forms the 

 main faunal component, and an elucidation of the groups into which the species fall 

 will then be relevant. 



Included taxa. The subgenus includes the following forms from the Regions 

 indicated : — 



Palaearctic Region : all species-group taxa assigned to Simulium Latreille and 

 Gnus Rubzov in Rubzov's (1959-1964) monograph, and all species-group taxa 

 except the ornatum-gvoup assigned to Odagmia Enderlein by Rubzov (op. cit.). 

 From the African area only one confirmed species : Simulium (Simulium) gaudi 

 Grenier & Faure (Morocco). In addition there are old records based on adults of 

 Simulium s. str. species from North Africa by Seguy (1930) for reptans L. and 

 subornatum Edwards, and from the Canary Islands by Santos Abreu (1922) for 

 reptans L., variegatum Meigen, cincta Meigen, and cinerea Macquart but there is 

 scarcely any doubt that these are all misidentifications. 



Nearctic Region : all species assigned to Simulium Latreille s. str. and Gnus 

 Rubzov by Stone (1965). 



Oriental Region : no comprehensive work exists to which reference can be made, 

 but the British Museum (Natural History) contains material of almost all described 

 Oriental species, and the following are here assigned to Simulium s. str. after 

 examination of types and other material in that collection : Simulium (Simulium)

 consimile Puri ; S.(S.) crassimanum Edwards ; S.(S.) dentatum Puri ; S.(S.) 

 digitatum Puri ; S.(S.) eximium de Meijere ; S.(S.) fenestratum Edwards ; S.(S.) 

 fuscopilosum Edwards ; S.(S.) gravelyi Puri ; S.(S.) grisescens Brunetti ; S.(S.)
