Type Material

The following notes on F. Smith type specimens have been provided by Barry Bolton (details):

Odontomachus ruficeps

Holotype worker in The Natural History Museum. The specimen matches the description very well but Smith merely gives “Australia” as the type-locality, whereas the specimen has, “O. ruficeps Sm. Type,” and “New Holl, 44/4.” Acc. Reg.: “1844 no. 4 New Holland n. and nw. coast. Presented by Haslar Hospital. Collected by Bynoe esq. Surgeoan R.N.”
