Remarks
We could only study historical material of this reportedly rare species, loaned from the RMNH. The specimen shows the distinct coarse reticulation on head and mesosoma (Fig. 6 B) that was already described by Förster and also mentioned, described, and imaged by subsequent authors (Pschorn-Walcher 1955, Townes 1977, Van Achterberg 2006). Note that Pschorn-Walcher (1955) wrote that the name H. rugosus Thomson should be preferred because Thomson’s material was, in contrast to Förster’s, still present. Pschorn-Walcher (1971) continued to use the name H. rugosus. Pschorn-Walcher (1955) designated a lectotype for H. rugosus, deposited at Stockholm Museum (SMNH). It is unclear if Townes (1977) was aware of this designation and was looking for the same specimens Pschorn-Walcher (1955) examined when he briefly reports the type as “ … lost, not found in Stockholm 1975 ”. Despite the allegedly lost primary type of H. nigripes, we agree with Townes (1977) that the statement describing the unique coarse sculpture by Förster leaves no doubt about the identity of the name. The absence of the primary type of H. nigripes is irrelevant. Therefore, H. nigripes is used here, maintaining the principle of priority.
