SIMULIIDAE OF AFRICA 123 



Existing type-material of Simulium damnosum consists of two conspecific 

 female syntypes, each bearing two handwritten labels reading ' Uganda Dr. 

 Christy ' and ' Simulium damnosum (Type) F.V.T.', and both in British Museum 

 (Natural History) ; the head of one syntype is missing. The syntype retaining 

 the head has been labelled and is here designated as lectotype : the head-less 

 syntype has been labelled as paralectotype.

 TYPE $ [by present designation], Uganda : BMNH, London. 



Roubaud described dentulosum from seven female specimens collected by 

 Neave and stated to be in the British Museum collection. Three of these female 

 syntypes now exist in the collection of BMNH, London, and one with data 

 ' Uganda Prot. Siroko R., near W. foot of Mt. Elgon. 3600 ft. Aug. 12-14, 191 1.

 Lectotype fixation as ' holotype ' by Freeman & de Meillon, 1953, Sim. Ethiop. 

 Reg. : 109. 



Original material of dubium consists of a pupa, pupal parts, and parts of one 

 adult female and one adult male (all syntypic material) from Morogoro, Tangan- 

 yika, mounted on five card mounts in pinned collection in British Museum 

 (Natural History) : Freeman & de Meillon (loc. cit.) cite the single male as 

 ' holotype ', restricting the name to a single specimen and thereby providing valid 

 fixation of a lectotype.
