Schoédler (1877) renamed S. acutirostratus as S. paradoxus. Con- 
sequently, the latter name is an objective junior synonym of the 
former. 
S. vidyae Rane and S. vidyae gajareae Rane were described from 
Jabalpur (India). The descriptions (Rane, 1983, 1986) are very 
detailed and provided with excellent illustrations, but do not contain 
any characters which differentiate these taxa from S. acutirostratus. 
The types are deposited in the National collection of the Zoological 
Survey of India (Calcutta). Sharma & Sharma (1990) sink both 
names into the synonymy of S. acutirostratus on the basis of 
investigation of these types.

rounde prominence separated above and below with depressions. 
Dorso-posterior valve prominence absent. Diameter of circle in- 
scribed in dorso-posterior valve angle very large. Dorsal margin 
without denticles. Proximal and distal supra-anal angles small, 
embayments of postabdomen shallow, proximal angle rounded.

REMARKS. There is no doubt that S. victoriensis and S. acutirostratus 
are separate species because they are sympatric and differ markedly 
from each other. 
Judging from illustration made by Haase (1903), the author 
examined specimens of S. victoriensis but erroneously identified 
them as S. acutirostratus.
