Sijua parvula sp. n. 



(PI. 20, fig. 105; PI. 44, fig. 248; PL 65, fig. 415) 



$. Wing, 7*5— 8*5 mm. Vertex pale brown, irons similar, flattened between eyes. Labial 

 palps with third segment 1/2 length of second, upturned, reaching vertex. Thorax brown. 

 Hind tibia with outer spur of distal pair 1/2 length of inner; inner spur of distal pair as long as 

 1st hind tarsal segment. Fore wing, pattern as in PL 20, fig. 105, brown, apex white with several 

 black spots between veins. Small black discal spot, some darker transverse marks, reticulations 

 obscure. Underside paler than upperside, white apical mark conspicuous. Iridescent scales along 

 costal margin under fore wing. Hind wing, colour and pattern as fore wing, darker transverse 

 fascia clearer than fore wing. Black spots on hind wing margin. 



Genitalia q* (PI. 44, fig. 248). Median basal process produced beyond margin of valve. No 

 cornuti in aedeagus. 



$. Wing, 8'5-q*5 mm. Similar to male but generally darker and often with dark costal 

 margin and grey (rather than white) apical patch. Underside with reddish tinge. 



Genitalia $ (PI. 65, fig. 415). Duct of bursa covered with minute sclerotized plate-like 

 spines. Bursa minutely spinose, no signum. 



Discussion. This species is structurally similar to 5. furcatula Pag. and S. 

 meriani Gaede. S. parvula can be separated from furcatula by its smaller size and 

 by the shape of the basal process of the valve of the male. From others in the 

 genus the small size of parvula readily separates it. The relationship between 

 parvula and meriani is not clear. At present meriani is only known from the badly 

 damaged holotype from the Seychelles but there are small differences between this 

 and parvula. The costal margin of the fore wing is more sinuous in parvula than 

 in the other species of the genus.

Sijua meriani (Gaede) comb. n. 

 (PI. 20, fig. 105a) 



Rhodoneura meriani Gaede, 191 7 : 376. 

 Rhodoneura meriani Gaede; Gaede, 1929 : 492. 



o". Wing, 8-5 mm. Head badly damaged. Antennae minutely ciliate. Proboscis present. 

 Labial palps broken. Fore wing, pattern as PL 20, fig. 105a, grey-brown with purplish tinge. 

 Underside with more distinct pattern. Apical white triangular patch with black spots between 

 veins. Median and basal reddish brown patches. Black scales in cell and along some veins. 

 Iridescent scales numerous on underside. Hind wings badly damaged. Abdomen missing. 



$. Unknown. 



Discussion. This specimen is badly damaged but it should be possible to match 

 it when other specimens are available from the Seychelles. From the fore wing 

 pattern, S. meriani is closely related to S. parvula. At present, parvula is known 

 only from West Africa but there is a general similarity to the Seychelles specimen
