説明
A hypogeal atyid shrimp, Halocaridinides trigonophthalma (Fujino and Shokita, 1975), is newly recorded from Hatoma Island, Southern Ryukus, Japan, and Hatoma Island becomes the fourth island which H. trigonophthalma occurs. H. trigonophthalma was collected from the old well, which is 7-8 m in depth and its wall seem to consist of limestone. There was about 1.0 by 1.5 m clear water pool on the bottom of well, with about 10 cm in depth and sedimental soil and broadleaves, roughly dozens of small shrimps were observed. Water was licked but salinity was not felt. Detailed description of the specimens obtained shows that the numbers of spines on diaeresis of uropodal exopod overlap with the only congener, H. fowleri (Gordon, 1968), though Gurney (1984) assigned the fewer number of spines as one of two distinguishable characters between two species. Instead, the relative length of distal end of endopod peduncle of antenna and the relative length of exopod of 3rd maxilliped can differentiate H. trigonophthalma and H. fowleri.
