Limatula chilensis sp. nov. A new Limidae (Mollusca: Bivalvia) from northern Chile
Limatula chilensis sp. nov. is described on the basis of shell morphology and soft tissue anatomy. Studied individuals were obtained periodically between June 2008 and January 2009 from sublittoral soft-sediments off Punta Coloso in northern Chile at depths of 22 to 33 m. Shell morphology of the new...

| Sumario: | Limatula chilensis sp. nov. is described on the basis of shell morphology and soft tissue anatomy. Studied individuals were obtained periodically between June 2008 and January 2009 from sublittoral soft-sediments off Punta Coloso in northern Chile at depths of 22 to 33 m. Shell morphology of the new species differs from the 4 described species of Limatula from the Pacific coast of South America and Antarctic Peninsula (5°-65°S). Main characteristics of L. chilensis include an average height of 3.50 mm (range 2.36-4.42, SD ± 0.60, n = 34), number of radial ribs 16-21 (mode = 20, SD= 1.69, n = 8) and greater shell obliqueness. L. chilensis is the only known species of the genus found off northern Chile. |
