Catinella is agenus of snails from the family of amber snails (Succineidae) in the suborder of land snails (Stylommatophora). The genus Catinella, which isessentially based on housing morphological criteria,is polyphyletic according to recent molecular genetic studies.

features

The cases of the representatives of the genus Catinella are ovate to flattened ears with 1.5 to 2 turns. They are up to 16 mm high and 10 mm wide. The shell is generally very thin. The color varies from horn-colored, yellowish to greenish-yellowish. The embryonic casing is smooth, the following turns show only slight radial wrinkles. The mouth is very large, often with a thin lamella on the edge of the spindle. The mouth rim is thin and not thickened (with the exception of the lamella on the spindle edge).

The spermatic duct is only moderately long in the reproductive system. It opens into the penis at the apex. The penile retractor muscle attaches to the apex or a little below the apex. The penis is short, thick and cylindrical to almost spherical. There are some large, fleshy lengthways pilasters inside . The free fallopian tube is comparatively short and there is no actual vagina . The seminal vesicle (spermathec) is round and large, the stem is slender and short to very short.

Geographical distribution and habitat

The species of the genus Catinella are restricted to mostly tropical Pacific islands.

Taxonomy

The taxon was established by William Harper Pease in 1870 . Type species is Catinella rubida Pease, 1870. The salt amber snail ( Quickella arenaria ), which also occurs in Germany , has long been part of the genus Catinella . Quickella Boettger, 1939, with the only species Quickella arenaria (Potiez & Michaud, 1838) differs significantly from Catinella in terms of the shape of the housing and, above all, in the genital system . Catinella Pease, 1870 is the type genus of the subfamily Catinellinae Odhner, 1950. The following list of species is very uncertain, as there has not yet been a newer revision of the genus.
