A NEW SPECIES OF NACADUBA MOORE (LEPIDOPTERA: LYCAENIDAE) FROM NIUE, SOUTHWESTERN PACIFIC OCEAN

摘要

Nacaduba niueensis sp. n. is described and illustrated from Niue in the southwestern Pacific Ocean. The status of the previously illustrated female of this species is clarified.Miller and Miller (1993) recorded three species of Lycaenidae from the island of Niue. These included a species they tentatively identified as Spalgis sp., plus Jamides bochus argentina Prittwitz, 1867 and Zizina otis mangoensis (Butler, 1884). In theirpaper, they suggested that the first mentioned species, of which they had a single female specimen, may belong to the genus Spalgis Moore, 1879 as it bore 'markings reminiscent of Spalgis epeus (Westwood, [1851]), and particularly, S. e. nubilus Moore, [1884] but bolder and more pronounced.' While they described and illustrated the female and the female genitalia of this specimen, they did not describe it as a new species. I collected a single male specimen, clearly the same species as that illustratedby Miller and Miller (1993), on Niue in December 2009. Examination of both specimens showed they did not belong to the genus Spalgis and they are described here as a new species in the genus Nacaduba Moore, [1881].
