Lpeurus languidus Kellogg & Kuwana, 1902

The original description of Lipeurus languidus by Kellogg & Kuwana (1902: 475) was based on specimens collected from eight different host species. Kellogg (1906: 319) added four further hosts for L. languidus . Subsequent collections show that only two ( Oceanites gracilis and Oceanodroma tethys ) of those 12 hosts are natural and regular hosts for H. pelagicus (see material examined above). Hopkins & Clay (1952: 164) selected Oceanites gracilis as the type host for L. languidus . However, the specimen figured by Kellogg & Kuwana (1902: pl. 29, fig. 8) is a male from Oceanodroma tethys mounted on slide 1047b ( CISC), which was labelled as the lectotype by Theresa Clay at an unknown date. From the literature available, it appears that neither Clay nor anybody else published the designation of that lectotype. Therefore, as I agree with Clay’s informal proposal, I herewith designate the same male on slide 1047b as the lectotype of L. languidus Kellogg & Kuwana, 1902 . The female from the same host species on slide 1047a ( CISC), with the same data as the lectotype (see material examined above), is a paralectotype. Consequently, Oceanodroma tethys becomes the type host of L. languidus . The taxonomic purpose of this designation is to clarify the status of the type specimens and to fix the type host of L. languidus .
