Bioacoustics of Zosterops semperi

COMMENTS: No type was designated in the original description, Hartert only saying that the Rothschild Collection had ‘‘received a large series from Ruk.’’ Hartert (1920: 435) listed as the type the only specimen collected on 7 May 1896 , thereby designating it the lectotype . The Owston label is marked ‘‘Type’’ in what appears to be Rothschild’s hand, and it also bears a Rothschild type label. Mees (1969: 157) did not appear to accept Hartert’s designation of lectotype , although he usually did so, and only listed part of the type series even though he examined the specimens in AMNH. Hartert’s published designation applies to a unique specimen from the original type series, and this is sufficient for lectotypification. The following are paralectotypes , collected on Chuuk in November 1895 , February, March, May, and June 1896 : AMNH 700791– 700802 , 700804–700811 . Mees (1969: 143–144) included the Caroline Islands white-eyes in the broad species Z. conspicillatus . Pratt et al. (1987: 283–284) , based on song, included the subspecies semperi , owstoni , and takatsukasai in the species Z. semperi , and the recent mitochondrial sequence data of Slikas et al. (2000: 355–365) support this arrangement.
