Rhodoneura catenula (Pagenstecher) ; Dalle Torre, 1914 : 21. 

 Rhodoneura catenula (Pagenstecher); Gaede, 1917 : 367. 

 Rhodoneura catenula (Pagenstecher); Gaede, 1929 : 491. 



o*. Wing, 16-5-20 mm. Vertex brown, irrorate with light brown. Frons similar, rounded. 

 Labial palps with third segment 1/3 length of second, upturned, reaching vertex. Length of 

 palp approximately equal to diameter of eye. Thorax brown. Hind tibia with inner spur 

 of proximal pair very slender with clavate end, outer spur of distal pair slightly more than 1/2 

 length of inner spur; inner spur of distal pair 1/2 length of first hind tarsal segment. Fore wing, 

 pattern as in PI. 12, fig. 57, grey-brown with darker brown median and basal areas. Prominent 

 reticulations. Underside paler, five or six patches of black scales (PI. 12, fig. 58) surrounded 

 by yellow scales in cell. Apex of cell with scattered yellow scales. Hind wing, colour and 

 pattern as fore wing but no black and yellow spots on underside. Sc+R x approaches Rs but 

 does not join it. 



Genitalia <$ (PI. 37, fig. 206). Aedeagus with shorter cornuti than gemmata. 



$. Wing, 22-23 mm. Colour and pattern as male. Labial palps with third segment 1/2 

 length of second. Hind tibia with proximal and distal pair of spurs almost equal in size, 

 proximal pair not slender as in male. 



Genitalia $ (PI. 60, fig. 366). Anal papillae broad, no signum. 



Discussion. This species is closely allied to gemmata, the grey-brown colour, 

 rather than red-brown, separating this species from gemmata. There are also 

 differences in the length of the gnathus and in the shape of the processes on the 

 uncus. In a series there is little difficulty in distinguishing catenula from gemmata. 

 However, until more is known of the biology of these two species there is an element 

 of doubt about their relationship. Gaede (1929) considered gemmata might be a 

 form of catenula but no intermediates have been found in the series examined. In 

 the original description of catenula Pagenstecher gives "Natal" as the type-locality 

 and says that the type-specimen is a female. The specimen in the Zoological 

 Museum, Berlin, labelled "origin" and with Pagenstecher's labels is a male from the 

 Cameroon. No recent specimens of this species having been found in South Africa, 

 it seems possible that the locality "Natal" given in the original description was an 

 error. I am therefore regarding Cameroon as the type-locality for this species.
