DISCUSSION: Edwards (1961: 152) examined the two syntypes of Lipeurus diversus var. major , and qualified them as stragglers. I agree with Edwards in regarding those syntypes as stragglers, but I have not been able to examine them. In the course of my research on the lice from the Galápagos Islands, I have examined all specimens from those islands included in the Kellogg Collection held at CISC. Unfortunately, the syntypes of L. diversus var. major were not among them. Although Edwards (1961: 151) clearly indicated that H. (H.) intermedius was a nomen novum, he still designated a holotype, an allotype and paratypes for his new name. That designation contravenes Article 72.7 of the I.C.Z.N. (1999) Code, which states that the types of a nomen novum are the same as those of the preocuppied name it replaces. Therefore, the specimens listed above as “ types ” of H. (H.) intermedius are, in fact, not types.

The Timmermann (1960: 330, fig. 16b) illustration of the female last segment, taken from the allotype of H. noctivagus , has a clear angular indentation in its distal margin. However, all females listed above—identified as H. noctivagus according to males in the same samples—have terminalia with a slightly convex distal margin ( Fig. 53 ). Timmermann (1965: 152) realised that females described by Edwards (1961: 138, fig. 4S) from the same host were much larger than the allotype of H. noctivagus and that also differed from it in the shape of the distal margin; therefore, he admitted that the “allotype” belonged to another species, not H. noctivagus .
