CLASSE: GASTROPODA: TERRESTRE

FAMÍLIA: MEGASPIRIDAE

ESPÉCIE: Megaspira pilsbryi Rehder, 1945

Tamanho médio: 35 – 40 mm

Habitat:  Mata Atlântica

Ocorrência: Brasil (Rio de Janeiro)

Localidade tipo: Rio de Janeiro

Nome original: Megaspira pilsbryi Rehder, 1945

Etimologia: o nome da espécie é uma homenagem a  Henry Augustus Pilsbry (Iowa 1862 – Flórida 1957). Pilsbry foi um biólogo, malacólogo e carcinólogo. Notabilizou-se mundialmente pelo seu estudo dos moluscos (Mollusca), em particular dos Polyplacophora e dos gastrópodes terrestres

Descrição original:

(Rehder, 1945): “A Note on Megaspira elata Gould.* — On critically examining the type of Megaspira elata Gould 1847 (U.S.N.M. 5503), collected in Brazil by the United States Exploring Expedition, I discovered that it is Megaspira elatior Spix 1827, agreeing with it in sculpture and in the internal armature. The species described as Megaspira elata Gould by Pilsbry (Man. Conch, (ser. 2), vol. 16, p. 186, pi. 28, figs. 5, 6; pi. 29, figs. 12, 13, 1904) differs in having more crowded, less retractively inclined ribs and in having the radial basal lamellae lower and without hooks. This species may be called Megaspira pilsbryi, new name ( = M. elata (Gould) Pilsbry 1904, not Gould 1847).

It is apparently a rarer shell than Megaspira elatior. In the collections of the U. S. National Museum there is only one specimen of pilsbryi, and 6 of elatior; I have also seen the two specimens of pilsbryi from the collections of The Academy of Natural Sciences of Philadelphia (Cat. Nos. 3057 and 25041), which are figured on plate 28 of the Manual.

It may be noted that the species figured by Gould as Megaspira elatior Spix (U. S. Explor. Exped., vol. 12, Moll, and Shells, pi. 7, fig. 102, 1852) (U.S.N.M. No. 5504), and the other specimens so labeled and also collected by the Exploring Expedition (U.S.N.M. No. 22073), are all Megaspira ruschenbergiana ‘Lea’ Jay. — 11. A.”
