| Oeconesus lobatus Wise, 1958 | |
Oeconesus lobatus is a species of caddisfly belonging to the family Hydrobiosidae. The species was first described by Keith Arthur John Wise in 1958, and is endemic to New Zealand.
Taxonomy
The species was identified by Wise in 1958, based on a specimen collected from Raurimu in 1919 by C. E. Clarke. Some sources such as Ward (1999) consider O. lobatus to be a junior synonym of O. maori.
Description
Wise's original text (the type description) reads as follows:
Length of anterior wing, 13 mm (0.51 in). Abdomen♂. Fifth abdominal segment with a pair of lateral processes. Genitalia♂. Dorsal margin of ninth segment produced in two large rounded lobes with a slight transverse ridge across their bases. Beneath each lobe is a narrower process directed slightly upwards. Upper penis-cover large, produced upwards, narrowly excised to form two forks lying parallel and very close together, these forks being truncate in dorsal view. Inferior appendages three-jointed, a stout basal joint with two terminal joints arising from its inner surface, one membranous and finger-shaped, the other more strongly chitinised, sharply excised ventrally towards the apex, directed inwards, and with a small tooth at apex. Penis membranous, expanded at apex with a chitinised process on each side pointing latero-ventrally, and with some chitinisation at the opening of the ejaculatory duct.
Distribution and habitat
The species is endemic to New Zealand.
