Bathraula Meyrick, 1919, Exotic Microlepidoptera, vol. 2, p. 237 (type species: 

 Cryptolechia simulatella Walker, 1864, Sarawak); 1922, in Wytsman, Genera 

 Insectorum, fasc. 180, p. 49. — Fletcher, 1929, Mem. Dept. Agiic. India,

 vol. 5, p. 485, pi. 238, figs. 1-1 e (syn. of Syntomaida Meyrick). 



Bathybalia Diakonoff, 1954, Verb. Ned. Akad. Wet., Nat., ser. 2, vol. 50, no. 1, 

 p. 86 (type species: B. microsperma Diakonoff, 1954, New Guinea), 

 [new synonym]. 



I am now satisfied that the genus Bathybalia is a synonym of 

 Syntomaula. Clarke pointed out to me that Bathraula is another 

 synonym. This remarkable genus is puzzUng by aberrant neuration 

 of the hindwing; the species have the size and appearance, and one of 

 them also the coloring and markings of a Palaearctic Yponomeuta. 

 One would not attribute them to the Cosmopterygidae lightly. The 

 male genitalia, however, are convincing, although they are strongly 

 speciahzed and aberrant. Both Syntomaula and "Bathraula" were 

 originally attributed to the Oecophoridae, the latter genus subse- 

 quently relegated to the subfamily or tribe Scaeosophides by Meyrick 

 which he later raised to the family rank Scaeosophidae. I placed 

 "Bathybalia" also in the last mentioned family. Clarke, however, 

 pointed out (1955, vol. 2, p. 21-22) by his study of the type species 

 of Scaeosopha Meyrick that it was a true Cosmopterygid and that the 

 family name "Scaeosophidae" should be suppressed. 



At present there are three known species of Syntomaula. 



Key to the Species of Syntomaula 



1. Whitish or greyish, dotted with black 2 



White, mixed with pale greyish ochreous, markings fuscous (Ceylon). 



S. tephrota 



2. Eighth tergite with the hook-shaped dorsal process slightly shorter than the 



remaining sclerotizcd part of tergite; one short ventral process only. 



S. microsperma 

 Eighth tergite with the dorsal process less curved, longer than the rest of 

 tergite; one ventral and one dorsal short process.
