olivacea Macquart, 1851 , Aricia

Aricia olivacea Macquart, 1851b: 230 ( 1851d: 257) , pl. 23, fig. 12. Lectotype ♂, “ Tasmanie. Muséum.” ( Australia, Tasmania), by designation of Albuquerque (1950a: 244), in MNHN.

MATERIAL. — There is 1 ♂ syntype in MNHN under no. 2399 of the Macquart collection. It has the accession no. 3.47 (Tasmania, collector Verreaux) and it is labelled by Macquart “ Aricia / olivacea / ♂. Macq. n. sp.”. It is rather mouldy and quite damaged: antennae, both mid tarsi, and both hind legs missing ; right wing broken at base and very loose; thorax and head rubbed. It was designated as lectotype by Albuquerque (loc. cit.) .

CURRENT IDENTITY. — Albuquerque (1950a: 242- 244, figs 5, 6) assigned this species to the genus Helina Robineau-Desvoidy, 1830 , and gave a redescription. The species is correctly placed in Helina as currently understood ( Pont 1989b: 686), and appears to be a distinct species close to H. micans Malloch, 1922 , and H. aeneiventris Malloch, 1922 , according to Malloch’s (1925) key: calypters and halteres pale, three postsutural dorsocentral setae, well-developed presutural acrostichal setae (scars only), foretibia without a posterior seta, palpi black, meron setulose below spiracle, posterior spiracle with setae on hind margin. In colour and general habitus, it resembles H. micans or H. subpubescens (Macquart, 1847) . It differs from H. micans and H. aeneiventris most obviously by the much narrower frons, which at narrowest point is hardly broader than diameter of anterior ocellus.
