Abstract

In this study, Acanthogyrus (Acanthosentis) persicus n. sp. is described from Periophthalmus waltoni Koumans, 1941 in Qeshm Island, Iran. P. waltoni is a species of oxudercine gobies, with a wide range of habitats including mangrove forests and tidal mudflats of the Persian Gulf. It is known as a biological indicator to monitor evolutionary processes. A. (A.) persicus n. sp. is recognized by having a small trunk entirely covered with spines and a unique proboscis armature. Large hooks of the anterior circle are widely separated from very small hooks of the middle and posterior circles. Comparison of the length ratio of anterior hook/middle and posterior hooks among different Acanthosentis species showed a value of approximately four only for our new species and Acanthogyrus (Acanthosentis) barmeshoori, though the new species is distinguished from A. (A.) barmeshoori by the absence of a para-receptacle structure and the presence of spines covering the entire trunk. In addition, A. (A.) persicus bears lateral hooks in the anterior circle that are smaller than other hooks in the same circle, displaced posteriorly. The prevalence rate of acanthocephalan infection of P. waltoni was 5%. This study is the first report of Acanthosentis infection of P. waltoni in Iran. Further studies are required to evaluate the acanthocephalan fauna of other mudskippers such as Boleophthalmus and Scartelaos.

1941 年伊朗 Periophthalmus waltoni Koumans 的新 Quadrigyrid 物种描述

摘要

在这项研究中，棘突（Acanthosentis）persicus n. sp. 描述于1941 年在伊朗格什姆岛的Periophthalmus waltoni Koumans。P. waltoni是一种氧化虾虎鱼，栖息地范围广泛，包括红树林和波斯湾的潮汐泥滩。它被称为监测进化过程的生物指标。A. ( A. )  persicusn. sp. 它的特点是有一个完全被刺覆盖的小树干和一个独特的长鼻骨架。前环的大钩子与中环和后环的非常小的钩子相距甚远。不同间前钩/中，后钩的长度比比较Acanthosentis物种显示出约4只为我们的新物种和一个值Acanthogyrus（Acanthosentis）barmeshoori，虽然新种区别于A.  （甲）  barmeshoori由没有旁接受结构和覆盖整个躯干的刺的存在。此外，A. (A.) persicus前环的侧钩比同环的其他钩小，向后移位。P. waltoni棘头菌感染的流行率为5%。本研究是伊朗首次报道P. waltoni感染棘皮病。需要进一步研究来评估其他弹涂鱼（如Boleophthalmus和Scartelaos）的棘头动物群。
