Abstract: Monosolenia asymmetrica Hyman, 1953 Monosolenia asymmetrica Hyman, 1953a: 359–362, figs 127–129 (type locality: Cabo San Lucas, Baja California Sur). Monosolenia asymmetrica – Brusca 2005: 69 (checklist). Distribution Cabo San Lucas, Baja California Sur, Mexico. Habitat Benthic. Remarks The species is characterized by an oval-oblong body. It has 20–26 cerebral eyes distributed in two lines towards the region anterior to the tentacular eyes, which are distributed circularly; it has 20–25 tentacular eyes and lacks nuchal tentacles. The male reproductive system features a bulbous seminal vesicle, a pyriform prostatic vesicle, and a short and inert conical penis papilla. The female reproductive system features an asymmetrical female gonopore positioned to the left of the central axis of the body (position based on the scheme proposed by Hyman 1953a: 360, fig. 127), a moderately long female atrium, a narrow Lang’s duct, and an elongate, deeply lobed Lang’s vesicle.
