Material examined.

1♀, Sri Lanka (Ceylon), deposited in London, type no. 18. 314 (NHM).

Remarks.

Wickwar (1908) described this specimen as belonging to the genus Odynerus Latreille. Having examined the same specimen, Giordani Soika (1941) placed Odynerus subfistulosus in the subgenus Stenodyneroides and then added the following characters: superior carina of propodeum dentiform, tergum I sub-square, basally truncated, slightly wider than long, and its lateral margins parallel, tergum II very slightly longer and slightly wider than tergum I and strongly reflected at the apex. With those characters in mind, we examined the holotype specimen and found that more characters match to those of the genus Pararrhynchium , such as one large cephalic fovea on the vertex (Fig. 23 ), the clypeus coarsely punctate and more or less emarginated at apex (Fig. 24 ), the scutellum and mesoscutum flattened (Fig. 22 ), the propodeum with a superior carina (Fig. 26 ), and tergum I with transverse carina basally (Figs 25 , 26 ). Therefore, we suggest that Odynerus subfistulosum Wickwar, 1908 should be transferred to the genus Pararrhynchium .

Distribution.

Sri Lanka.
