Cythara is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae.[1]

This name is considered a nomen dubium.[1] Hedley (1922: 260) and Powell (1966: 109) summarized the arguments against using the earlier name Cythara Schumacher, 1817, with much uncertainty regarding the identity of its type species, against Eucythara Fischer, 1883. The name has also been used by European authors (e.g. Knudsen, 1952; Nordsieck, 1977) for species classified now in Mangelia Risso, 1826.[1]

Description

The tropical shell is relatively large. It is columbelliform and longitudinally costellated. The spire is short. The aperture is narrow and elongated. The outer lip is denticulated within. The columellar lip is striated.[2]

The margin of the mantle is slightly dilated on the right side.

The shell is fusiform, smooth and longitudinally plicated or rihbed. The aperture is linear, posteriorly subemarginate. The siphonal canal is very short and nearly straight. The columella is subflexuous and transversely striated. The inner lip is posteriorly callous. The outer lip is margined, denticulate, or striated internally.[3]
