Humboldtianidae is an American family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). ==Anatomy== The anatomy of this family is defined by the presence of a diverticulum and three to four dart apparatuses (the love dart is used in mating behaviour). They always have the same number of dart sacs and mucus glands, with two darts per dart sac. The mucus glands are situated on, and open into, the vagina, above the dart sac.〔 ( Higher classification of the Helicoidea and the molecular analyses of their phylogeny (by Hartmut Nordsieck) )〕
