A new species belonging to the leiognathid genus Photolateralis, collected from the coastal waters of Oman, is described herein. Photolateralis is unique among leiognathid genera in possessing a species-specific translucent midlateral flank stripe that may be comprised of either multiple independent translucent windows (P. stercorarius, P. moretoniensis, and the new species) or a continuous translucent lateral band (P. antongil). Photolateralis polyfenestrus, new species, is distinguished from congeners by the presence of a short, composite midlateral stripe comprised of three small, rounded translucent windows (vs. numerous windows in both P. stercorarius and P. moretoniensis, or a continuous translucent stripe in P. antongil), and that is confined to the midflank (vs. extending a majority of the length of the flank in congeners). The new species is further distinguished from both P. moretoniensis and P. antongil by a shallower body, and from both P. stercorarius and P. moretoniensis by a pigmentation pattern above the lateral midline comprised primarily of larger rounded blotches (vs. smaller sinuous lines and markings comprising a vermiculated pattern). Photolateralis polyfenestrus is characterized by a lower jaw that is deep and convex in lateral view (vs. mostly straight in congeners, excluding P. antongil), and that forms an angle of between 60°–70° to horizontal (vs. less than 45° in congeners, excluding P. antongil). The only other species of Photolateralis reported from the Western Indian Ocean is P. antongil, to date only known from the coastal waters of Madagascar, whereas both P. stercorarius and P. moretoniensis have ranges restricted to the western Pacific and extending into the eastern Indian Ocean.

来自阿曼湾的一个新种马鲛（Teleostei：Leiognathidae：Equulitini：Photolateralis）的描述

本文描述了从阿曼沿海水域收集的属于 leiognathid 属 Photolateralis 的新物种。Photolateralis 在 leiognathid 属中是独一无二的，因为它具有物种特异性的半透明中外侧条纹，该条纹可能由多个独立的半透明窗（P. stercorarius、P. moretoniensis 和新物种）或连续的半透明侧带（P. antongil）组成）。Photolateralis polyfenestrus 是新物种，与同类的区别在于存在由三个小的圆形半透明窗口组成的短复合中侧条纹（相对于 P. stercorarius 和 P. moretoniensis 中的多个窗口，或 P. 中的连续半透明条纹） . antongil），并且仅限于中侧翼（与在同类中延伸大部分侧翼长度相比）。新物种通过更浅的身体与 P. moretoniensis 和 P. antongil 进一步区分，与 P. stercorarius 和 P. moretoniensis 的区别在于侧中线上方的色素沉着模式主要由较大的圆形斑点组成（与较小的弯曲线相比）和包含蠕虫图案的标记）。Photolateralis polyfenestrus 的特点是下颌深且侧视凸出（与同族群中大部分直，不包括 P. antongil），并且与水平面形成 60°–70° 之间的角度（与小于 45 ° 在同源物中，不包括 P. antongil）。从西印度洋报道的唯一其他 Photolateralis 物种是 P. antongil，迄今为止仅在马达加斯加的沿海水域中发现，而 P. stercorarius 和 P. stercorarius。
