features
The body of the Capilloventridae has four pairs of bristles on each segment (two pairs on the back and two on the belly), of which one bristle - also on the belly side - is designed as a hair and the other as a hook.
The animals have a pair of testes in the 11th segment and a pair of ovaries in the 12th segment. Male atria, prostates, and penises are absent. The pair of receptacula seminis open out laterally at the transition from the 6th to the 7th segment, with the ampoules in the 7th segment. The pair of male sexual openings is located in a copulation pocket in the 12th segment, the pair of female sexual openings in the 13th segment.
