广泛分布的热带虾虎鱼属Oxyurichthys是单系的，因为它的物种共享两个被认为是来自虾虎鱼亚科（Gobionellinae）的狭虾虎鱼组的特征，一个横向加宽的（匙形）第三神经棘，通常是双叉的，没有前鳃盖头侧管。它与同样产于印度西太平洋的寡鳞属（Oligolepis）和大西洋东太平洋的栉虎鱼属（Ctenogobius）关系最为密切。本文记述了尖尾鱼属16个有效种，并描述了4个新种，即尖尾鱼属O. limophilus，印度洋西部的O. rapa和O. chinensis和O.来自西太平洋的泽塔19个物种共有两个额外的共形，一个圆形的肉质舌头和一个缺乏细长后支柱的腭，并形成了在南非和马达加斯加已知的近形尖尾鱼的姐妹群。一个种O. stigmalophius，出现在大西洋西部。在东太平洋大陆和东大西洋没有该属的记录。西非几内亚湾地区的早期记录提到了Gobionellus occurentalis。许多Oxyurichthys物种仅限于浅河口和沿海沃茨与底质的淤泥或其他细沉积物，但几个已知的深度超过10米，往往是由拖网捕捞。
The widespread tropical gobionelline fish genus Oxyurichthys is monophyletic due to its species sharing two characters considered derived within the Stenogobius Group of the Gobionellinae (Gobioidei: Gobiidae), a transversely broadened (spatulate) third neural spine that is usually bifid, and no preopercular cephalic lateralis canal. It is most closely related to Oligolepis, also of the Indo-west Pacific, and Ctenogobius, an Atlantic-eastern Pacific genus. Sixteen valid species of Oxyurichthys are redescribed and illustrated and four new species are described, O. limophilus from the western Indian Ocean, O. rapa from French Polynesia, and O. chinensis and O. zeta from the western Pacific. Nineteen species share two additional synapomorphies, a rounded fleshy tongue and a palatine lacking an elongate posterior strut, and form the sister group to the plesiomorphous Oxyurichthys keiensis, known from South Africa and Madagascar. One species, O. stigmalophius, occurs in the western Atlantic. There are no records of this genus from the continental eastern Pacific or the eastern Atlantic. Previous accounts from the Gulf of Guinea region of West Africa are references to Gobionellus occidentalis. Many Oxyurichthys species are limited to shallow estuarine and coastal waters with bottom substrates of silt or other fine sediments, but several are known from depths exceeding 10 m and are often collected by trawling.
