Isomeria inexpectata Solem, 1966

CLASSE: GASTROPODA: TERRESTRE

FAMÍLIA: LABYRINTHIDAE

ESPÉCIE: Isomeria inexpectata Solem, 1966

Tamanho médio: 23.3 – 24.6 mm

Ocorrência: Colômbia (Magdalena)

Localidade tipo: Colômbia, Magdalena, “Siminchucua River, between San Sebastián de Rábago and Mamancanáca, headwaters of River Fundación, south slope of Sierra Nevada de Santa Marta”

Altitude: ~2,590–2,740 m

Ecologia: Segundo Borrero, 2012: “All specimens were collected dead, and no ecological information was recorded. The vegetational zonation corresponding to elevations in the range of 2500–3000 m at this locality is Andean Forest (Breure 1984). This southern slope of the SNSM exhibits relatively drier conditions as compared to the wetter climate of the northern slope (Pérez P. 1984)”
