# Bradybaeninae

Bradybaeninae is a taxonomic subfamily of medium-sized to small land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. Members of the subfamily Bradybaeninae are defined by the presence of two divided glands with one to two accessory sacs.

## Description

Some genera of snails in this subfamily create and use love darts as part of their mating behavior. The dart sac contains one to two glands. They are also defined by missing a diverticulum.
In this subfamily, the number of haploid chromosomes present lies between 26 and 30.

## Distribution

Species of the subfamily Bradybaeninae are found mainly in Asia, with only one species, Fruticicola fruticum, occurring in north-western Europe.

## Taxonomy

The name of both the subfamily and the genus Bradybaena are derived from the Greek words bradus (= slow) and baino (= walk), meaning "slow walker".
Formerly considered as a separate family, molecular phylogenetic studies from 2007 showed that bradybaenids were closely related with the Camaenidae, a family that they are now considered a subfamily of. In these studies both Bradybaenidae and Camaenidae are mutually polyphyletic, and together form a monophyletic group. This finding suggested that the distinction between the clades was based essentially on the absence (Camaenidae) or presence (Bradybaenidae) of a diverticulum, and was arbitrary. This anatomical structure was apparently lost (or was gained) in several groups in convergence and is therefore not suitable for the delimitation of natural groups.
