Taxonomy
editThe species was identified by Wise in 1958, based on a specimen collected from Waitati in 1917 by C. E. Clarke.[3][4] No further specimens of the species were discovered until entomologist Brian H. Patrick discovered further specimens in 1992.[5][6] Patrick confirmed that the species was distinct from other members of Olinga, based on behavioural differences and the apparent inability to hybridise with O. feredayi.[5]
Description
editWise's original text (the type description) reads as follows:
ANTERIOR WING fuscous; scales of longitudinal fold and sub-terminal furrow ochreous, Membranes of both anterior and posterior wings fumose. Spurs 2.2.4. Length of anterior wing, 8 mm (0.31 in). Genitalia♂. Margin of ninth segment with a pair of long dorsal processes with a wart on each side and a pencil of hairs below the wart. Dorsal portion of ninth segment produced downwards posteriorly with upper penis-cover in form of two short processes arising distally below. Penis membranous. Inferior appendages broad at the base and twisted over dorsally towards the apex, each with a long, sinuous, pointed spine arising from its extreme base. These spines pass on each side of the penis and terminate above it between the penis-cover processes. Seventh sternite with a short, broad process.[3]
Males have a wingspan of 18.5 mm (0.73 in), with females larger at 22 mm (0.87 in).[5]
Wise noted that the species was visually similar to O. feredayi, but could be identified by O. fumosa being smaller, darker in colour, differences in genitalia and the seventh sternite.[3]
Distribution and habitat
editThe species is endemic to New Zealand,[3] found in the vicinity of Dunedin in the Otago Region and South Canterbury on the South Island of New Zealand.[5][6]
