摘要

Redigobius fotuno sp.nov.描述自印度尼西亚苏拉威西岛东南部穆纳岛的一个石灰岩天坑，与苏拉威西大陆特有的Redigobius penango（Popta 1922）最为相似，都具有粗壮的身体和圆形的头部、网状的体色模式以及纵向的眶下乳突列。然而，新种与后者的区别在于头长（标准体长的 35.3-38.4%）、上颚长（标准体长的 14.7-20.0%）和前胸长（标准体长的 43.4-46.0%）更大，骨盘细长，蹼薄（长度：标准体长的 21.7-26.2%；基部宽度：标准体长的 4.2-6.3%）。fotuno sp. nov.的这些独特形态特征可能与该物种的栖息地有关。

Redigobius fotuno, a new limnetic goby from Muna Island, Indonesia (Teleostei: Gobiidae)

Redigobius fotuno sp. nov., described from a limestone sinkhole on Muna Island, Southeastern Sulawesi, Indonesia, is most similar to Redigobius penango (Popta 1922), endemic to the Sulawesi mainland, both species having a robust body and rounded head, reticular body color pattern, and longitudinal suborbital papillae rows. However, the new species is distinguished from the latter in having greater head length (35.3–38.4% of standard length [SL]), upper jaw length (14.7–20.0% of SL) and predorsal length (43.4–46.0% of SL), and a slender pelvic disc with thin frenum (length: 21.7–26.2% of SL; base width: 4.2–6.3% of SL). These unique morphological characters of R. fotuno sp. nov. may be related to the limnetic habitat of the species.

期刊介绍： Ichthyological Research is an official journal of the Ichthyological Society of Japan and is published quarterly in January, April, July, and November. Ichthyological Research primarily publishes research papers on original work, either descriptive or experimental, that advances the understanding of the diversity of fishes. Ichthyological Research strives to cover all aspects of fish biology, including taxonomy, systematics, evolution, biogeography, ecology, ethology, genetics, morphology, and physiology.
