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.

腹部や付属肢の特徴から,石垣島・西表島産の陸生サワガニの新属(Ryukyum)がヤエヤマヤマガニNanhaipotamon yaeyamense Minei,1973に対し新設された.新属は腹板の構造,第3顎脚,雄の腹部,雄の第1腹肢・第2腹肢等にNanhaipotamonとの相違が見られる.ヤエヤマヤマガニは山間部の陸域に生息し,放卵期に湿地や水辺に集まる傾向がある.大卵を数少なく産む.
