Coutière (1905) described a subspecies <i>Alpheus gracilis alluaudi</i> based on material collected in the Maldives. According to Coutière (1905), the subspecies shows no secondary unguis on the dactylus of the third pereiopod. De Man (1911) described a variety of the species from the Lucipara Island as <i>A. gracilis luciparensis</i>. Banner & Banner (1983) studied various collections from Red Sea, Thailand, southern Philippines and Christmas Island, Maui and other Hawaiian Islands and listed three morphological variations for the species. These variations are categorized as: 1) Presence of deep or shallow orbito-rostral grooves, 2) Presence or absence of a projection on dactylar articulation of small chela, 3) Simple or bi-ungulate dactylus of third pereiopod. Based on these features, Banner & Banner (1983) concluded that this species shows a tendency to develop morphologically separated geographic lineages. All of our examined specimens show shallow orbito-rostral grooves, a projection on the dactylar articulation of small chela, and a biungulate dactylus of the third pereiopod.</p> |
