Psilochorema embersoni is a species of caddisfly belonging to the family Hydrobiosidae.[2] The species was first described by Keith Arthur John Wise in 1982, and is endemic to New Zealand.

Taxonomy

The species was identified by Wise in 1982, based on a specimen collected by Rowan Mark Emberson and C. A. Muir from the Murchison Mountains in Fiordland National Park, New Zealand.[3][4] Wise named the species after Emberson.[3]

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

Genitalia, ♂ (Figs. 1-3). Dorsal process (Segment X) membranous, elongate. Above superior appendages an internal curved spine together with an external rounded process on each side; superior appendages long, bent near middle. Inferior appendages short, stout, tapering to apex ventrally in lateral view, with apical inner teeth; dorsal arm wide, expanded apically; apical expansion bent inward with outer angle bearing a central tubercle; points of expansion sub-equal in length, bearing internal teeth. Aedeagus with mid-length lateral expansions and a dark apical dorsal flap.[3]

Wise measured the length of the forewings as 11.5 mm (0.45 in).[3]
