Phrantela bobbrowni Ponder & Clark, 1993

Diagnostic features

This species differs from all other Phrantela species in having a rather broadly ovate shell which resembles that of several species of Beddomeia in shape. It differs from all species in that genus, however, by having a rather long slit-like female genital opening, and an otherwise typical female genital system.

Original name: Phrantela bobbrowni Ponder & Clark, 1993 in Ponder, W. F., Clark, G. A., Miller, A. C and Toluzzi, A. (1993). On a major radiation of freshwater snails in Tasmania and eastern Victoria - a preliminary overview of the Beddomeia group (Mollusca: Gastropoda: Hydrobiidae). Invertebrate Taxonomy, 7: 501-750.

Type locality: Tributary of Giblin River, Tasmania.

Biology and ecology

In weed, plant debris and on wood. Egg capsules unknown but probably like those of another species of Phrantela; small, with single embryo, and covered in coarse sand grains. Development direct.

Distribution

The holotype of this species occurs in a small, swampy stream (tributary of Giblin River) where it is sympatric with a species of Austropyrgus and two other species of Phrantela: P. daveyensis tristis and P. angulifera. The species also occurs in a tributary of the Olga River (large stream) and in a small tributary of Dismal Creek (tributary of Hardwood River), SW Tasmania.
