nitida Macquart, 1851 , Aricia

Aricia nitida Macquart, 1851b: 231 ( 1851d: 258) , pl. 23, fig. 14. Lectotype ♂, “ Tasmanie. Muséum.” ( Australia, Tasmania), by present designation, in MNHN.

MATERIAL. — Described from both sexes. The syntype series, consisting of 1 ♂ and 3 ♀♀, is under no. 2401 of the Macquart collection in MNHN. The ♂ and 2 ♀♀ have the accession no. 4.46, whilst the 3rd ♀ has the number 3.47. Both refer to collections made in Tasmania by Verreaux. In addition, the ♂ has an old tag with the figure “46” and is labelled by Macquart “ Aricia / nitida / ♂. Macq. n. sp.”. The ♂ lacks left foretarsomeres 2-5 and right mid tarsomeres 2-5, but is otherwise in excellent condition. I have labelled it and designate it herewith as lectotype. The 3 ♀♀ have each been labelled as paralectotypes.

Albuquerque (1950b: 3) listed this material as “lectótipos ♂ e ♀ e 2 ♀ paralectótipos”. This is an invalid lectotype designation as it does not restrict the name to a single specimen.

CURRENT IDENTITY. — The lectotype belongs to the genus Helina Robineau-Desvoidy, 1830 , and is apparently a distinct species closely similar to H. caerulescens (Stein, 1910) ( Pont 1989b: 686) . It has three postsutural dorsocentral setae (a fortuitous fourth seta is present on one side), dark halteres and white calypters, and differs from H. caerulescens by the dense anteroventral to posterior setulae on hind tibia. It was redescribed by Albuquerque (1950b: 2, 3, figs 3, 4). The 3 ♀♀ are apparently conspecific.
