Not illustrated. 1898 Excerpt: ...emarginated by an uncolored space surrounding the stigmata; on the ventral aspect fulvous transverse bands, concave posteriorly; segment 7 with two longitudinal, lateral fulvous blotches; segment 8 with irregular black marginal bands; segment 9 wholly dark brown to black. Lipeurus diversus Kellogg. New Mallophaga I, 1896, p. 123, pi. viii. figs. 3 and 4. Many specimens from thirteen out of thirty-four individuals shot of the Black-vented Shearwater, Puffmus opisthomelus, from twelve out of fourteen individuals shot of the Dark-bodied Shearwater, P. griseus, from five out of six individuals shot of the Pink-footed Shearwater, P. creatopus, from a single specimen shot of P. bulleri, from a single specimen shot of P. tenuirostris, and a single specimen, probably straggler, from a Short-tailed Albatross, Diomedea albatrus (all the birds from the Bay of Monterey, California). The species was described from Pujjinus opisthomelas (same locality). This species and Lipeurus angusticeps Piaget (Les Pediculines, p. 306, pi. xxv, fig. 4) from Thalassidroma leachi, and Lipeurus abnormis Piaget (Supplement, p. 65, pi. vii, fig. 2) from Puf/inus major, are closely related. There is a regular sequence in size from angusticeps through diversus to abnormis. It may be suspected that we have to do with one species of great variation in size; but the diagnostic characters of the three species are sufficiently important to justify the separation of the forms. Lipeurus densus Kellogg. New Mallophaga II, 1896, p. 114, pi. vii, figs. 1 and 2. Two females and a male from a Short-tailed Albatross, Diomedea albatrus (Bay of Monterey, California). Types taken from Diomedea albatrus and D. nigripes (see Kellogg, Mallophaga from Birds of Panama, Baja California and Alaska, in New Malloph...
