Ponera scalprata

Holotype worker in. Labelled “N. Ind. 54/16.” Acc. Reg.: “1854 no. 16. N. India (Sikkim, Him.) From Dr Hooker’s collection. Collected by Dr Hooker during his travels in n. India. A few of the insects were from Khasya Hills.”

A second scalprata specimen is in, but here the usual data label is missing and has been replaced by a white card square with, “Phil. N. India.” The half-written then deleted Phil (= Philippines) raises the possibility that this specimen may not be from the original type-series.
