Two new species of snapping shrimps from the Indo-Pacific, with remarks on colour patterns and sibling species in Alpheidae (Crustacea : Caridea)

Abstract

tricolor, and fasqueli, two morphologically very close, but differently coloured species of snapping shrimps are described and illustrated. Descriptions are based on specimens imported from Indonesia and Sri Lanka. Both new species belong to the A. edwardsil group, and can be distinguished from all other species of by several features of the first and second chelipeds, liontal region, third maxilliped, and most readily by their conspicuous colour patterns. These attractive shrimps are regularly imported from Indonesia and Sri Lanka to Europe and Singapore, sometimes under the name Alpheus strenuus.
