Pseudoeconesus bistirpis is a species of caddisfly belonging to the family Hydrobiosidae.[2] The species was first described by Keith Arthur John Wise in 1958,[2] and is endemic to New Zealand.[3]

Taxonomy

[edit]

The species was identified by Wise in 1958, based on a specimen collected from the Tongariro area of the North Island Volcanic Plateau in 1930 by Alfred Philpott.[3][4] Pseudoeconesus tristirpis, which was identified in the same paper by Wise, became a junior synonym of Pseudoeconesus bistirpis in 1997.[5]

Description

[edit]

P. bistirpis is brownish-yellow in colour, with rows of minute spots freckled on its forewings.[6]

Wise's original text (the type description) reads as follows:

Testaceous; ANTERIOR WINGS closely irrorated with rows of almost colourless spots between the veins. WING VENATION. Apical forks of anterior wing sessile. Apical forks 1 and 3 of posterior wing stalked. Sc and R1 of posterior wing folded together for most of their lengths. Abdomen♂. Fifth abdominal segment with a pair of lateral processes. Length of anterior wing, ♂10 mm (0.39 in). ♀15 mm (0.59 in).[3]

The hindwings of P. bistirpis are similar to P. hudsoni, but can be identified due to the enlarged setae and inconspicuous humeral vein. [7]

Distribution and habitat

[edit]

Pseudoeconesus bistirpis is endemic to New Zealand,[3] and is found across the North Island and the upper South Island.[6] The species can be identified in traps year-round.[8] It is found in seepages in New Zealand bush,[6] and is believed to be reliant on forested ecosystems.[9]
