本文描述了采自柔佛诗巫岛和亭宜岛的两个尾形端足类新种。该新种的标本是用垂直拖网采集的，与现存的其他种类有明显的区别：第1-2颌足类相似，前足短而粗壮，扩张成轮廓不清的棕榈;大眼睛，上鳍3光滑。利用气升式取样器在海草区采集到的亭基尾刺（Urothoe tinggiensis）新种，其特征为：第5腹足具刚毛，眼小，第5腹足腕宽于腕，基节4个，第6-7腹足腕和腕均为线形。
Two new species of urothoid amphipods from Pulau Sibu and Pulau Tinggi, Johor are described and illustrated. The specimens of Urothoe sibuensis new species were collected by vertical haul plankton net and is distinctively different from other existing Urothoe species by these combination of special characters; similar gnathopods 1-2 with short and stout propodus expanded into poorly defined palms; large eyes and epimeron 3 smooth. Urothoe tinggiensis new species as collected using an airlift suction sampler at seagrass area is characterized by its different gnathopodal configuration with setose dactylus of 5th pereopod; eyes minute; carpus is wider than merus in the 5th pereopod; subquadrate coxa 4; merus and carpus of pereopods 6-7 are linear.
