Remarks: The male and female were not found together, and as matching sexes of Pseudocorinna on the base of somatic characters is particularly difficult, it is not certain that they belong together. Both the male palp and the female epigyne are simple, with a short embolus and short copulatory ducts, which might indicate that they indeed belong to the same species.

Diagnosis: Males of P. brianeno are characterized by the small bulbus occupying less than the posterior half of the bulbus. Females are recognized by the epigyne that is a large, roughly oval plate densely covered with warts, with two small bald spots and a transverse narrow rectangular area in front of the posterior margin.

Etymology: The species epithet is a noun in apposition and a patronym for Brian P.G. St. Jean de la Salle Eno, all-round artist and pioneer of minimal and ambient music, who revolutionized popular music in many ways.

Male palp ( Fig. 11E, F View Figure 11 ): RTA simple, short very slightly sinuous, rounded at tip; bulbus small, occupying only less than half of the cymbium; tegulum globular, without swelling but prolateral pointed extension; embolus short, strongly curved; FC of the same length, curved and parallel to embolus.

Epigyne ( Fig. 11C, D View Figure 11 ): a large darkened area covered in small warts; two small smooth areas in the centre; posterior margin with transverse smooth rectangular area preceded by dark semicircular spot on either side. Copulatory openings near lateral edge of rectangular area. Copulatory ducts very short, running obliquely to large spermathecae, which are less than their diameter apart. Without lobate ducts.
