species and their synonymy, reference should be made to this earlier paper. One 

 new species is described below (D. parvita). This species would key out in the fourth 

 couplet together with D. subsignata and D. lutescens in the previously published key 

 (Whalley, 1968 : 3). From both these species D. parvita can be separated by its 

 smaller size (wing 8 mm, parvita; 10 mm or over, lutescens or subsignata). 



The genus Dysodia is pantropical and is found on all continents except Australia. 

 Although widespread in Africa and India the genus does not occur in Madagascar or 

 the Seychelles. ("Dysodia" calidella Legrand, 1965, described from the Seychelles, 

 was transferred to the Pyraustinae, Whalley, 1968 : 1). 



Dysodia is a very distinctive genus with a characteristic external appearance. It 

 is probably related to Thyris Laspeyres which also has the dorsal process on the 

 tergum of the male genitalia, and other characters are common to both genera. 

 Further examination of Thyris Laspeyres, Hyperthyris Leech, Glanycus Walker and 

 Gippius Walker, all of which should be in the Pachythyrinae and comparison with 

 Dysodia is needed. 



Generic description. Labial palps three-segmented. Proboscis present. Eyes without 

 interfacetal hairs. Hind tibia with two pairs of spurs. Fore tibia with epiphysis. Tarsi with 

 rows of spines on each segment. Fore wing with some radial veins fused or from cell. Male 

 with prominent process ("hump") on tergum of genitalia. Female with secondary sac on bursa.
