THYRIDIDAE OF AFRICA AND ITS ISLANDS 127 



Discussion. This species is only known from the holotype. It seems most 

 closely related to K. kibala but is less heavily patterned and has different fore wing 

 venation. Until more specimens are found the relationship of this species with the 

 others in the group is not clear. Gaede (1929 : 495) suggested that this species was a 

 subspecies of "B. minutula" (=Striglina minutula Saal.) and he also suggested that 

 majuscula might be near hamatipex Hampson. In this latter suggestion he was 

 more nearly correct.

HYPOLAMPRUS Hampson 



Hypolamprus Hampson, [1893] 1892 : 364. Type-species, Microsca striatalis Swinhoe, by 



original designation.

The five species in this genus are separated into two species-groups on the basis 

 of different antennal structures. The curvifluus-group (curvifluus, distrinctus, 

 gangaba) have shortly ciliate antennae, the janenschi-group (janenschi, quaesitus) 

 have monopectinate antennae. H. curvifluus and H. distrinctus are similarly 

 patterned species, differing externally in size and colour. H. curvifluus is widespread 

 in Africa and is one of the few species of Thyrididae (other than those of the genus 

 Dysodia) which extend into South Africa. H. gangaba is similar to the Indian species, 

 R. bastialis on external characters but the genitalia are different. This species has 

 previously been (incorrectly) recorded from Africa. Few specimens of the species in 

 the janenschi-group have been examined and the relationship between these species 

 and those in the curvifluus-group is not clear. All the species in the genus have the 

 characteristic twin signa in the bursa of the females. This genus is related to 

 Hapana Whalley but can be separated from this genus by the origin of the radial 

 veins in the fore wing, these are from the cell in Hypolamprus but R 2 + R 3 are stalked 

 in Hapana. 



The genus Hypolamprus is known from Africa, the Indo-Pacific region and has one 

 species described from South America. It does not occur in Madagascar, the species 

 described in Hypolamprus (Whalley, 1967 : 36) has been transferred to Cornuterus 

 Whalley (page 135). 



Generic description. Antennae shortly ciliate or monopectinate. Labial palps 3- 

 segmented. Eyes without interfacetal hairs. Proboscis present. Fore wing usually with 

 radial veins from cell. Fore tibia with epiphysis. Hind tibia with two pairs of spurs. Tarsi 

 usually without spines. Male with simple uncus and valve. Gnathus usually a sclerotized 

 loop without median process. Female with two thorn-like signa in bursa, first part of duct 

 usually heavily sclerotized.
