A new species of Myra Leach, 1817 (Crustacea : Decapoda : Leucosiidae) from Timor Sea and South China Sea

摘要

A new species, Myra digitata, is established for two specimens collected over a century ago on Holothuria Bank, Timor Sea, and for material from South China Sea described as M. biconica Ihle, 1918, by Chen (1989, 1996) and Chen & Sun (2002). The new species is distinguished from M. biconica in having shallower frontal notch, much longer chelipeds, ovate, rather than rounded, carapace, and rounded, less prominent lateral posterior denticles on carapace. The species is described, fully illustrated, and synonymies are discussed.
