A Taxonomic Review of the Gobiid Fish Genus Rhinogobius Gill, 1859, from Taiwan, with Descriptions of Three New Species

本文重新整理臺灣產吻鰕虎屬（Rhinogobius）之分類。本屬魚種在臺灣共可分成兩個相似種群：極樂鰕虎種群（R. giurinus complex）與褐吻鰕虎種群（R. brunneus complex）。極樂鰕虎種群在臺灣僅有極樂吻鰕虎R. giurinus（Rutter，1897）一種，其餘八種均屬於褐吻鰕虎種群，包括明潭吻鰕假虎R. candidianus（Regan，1908）、名古屋吻鰕虎（臺灣亞種）R. nagoyae formosanus Oshima，1919；與六個世界新種：短吻褐斑吻鰕虎（R. rubromaculatus Lee & Chang，1996）、大吻鰕虎（R. gigas Aonuma & Chen，1996）、南臺吻鰕虎（R. nantaiensis Aonuma & Chen，1996）、細斑吻鰕虎（S. delicatus n.sp.）、班帶吻鰕虎（R. maculafasciatus n.sp.）、與恆春吻鰕虎（R. henchuenensis n.sp.）。其中前三種新種已被發表，後三種新種則於本文中描述。本屬魚種可藉由鰭條數、脊椎骨數、鱗列數、色斑等特徵，及其棲所、分佈地區等予以區分。文中並提供本屬各魚種之檢索表及各種之彩色標本照片，以利參考。

The taxonomic status of the freshwater gobiid genus Rhinogobius, specimens of which were collected throughout Taiwan is reviewed. Nine species of this genus are recognized which can be assigned into 2 species complexes. The R. giurinus complex has only a single species, R. giurinus (Rutter, 1897); and the R. brunneus complex contains the remaining 8 species: 5 valid nominal species (R. candidianus [Regan 1908]; R. nagoyae formosanus Oshima, 1919; R. rubromaculatus Lee & Chang, 1996; R. gigas Aonuma & Chen, 1996, and R. nantaiensis Aonuma & Chen, 1996), and 3 new species, R. delicatus, R. maculafasciatus, and R. henchuenensis. These species can be distinguished by the combination of fin ray count, vertebrae count, scalation, color pattern, habitat, and distribution. The 3 new species are described here with a key and specimen photos, as well as with morphological comparisons of all species of this genus distributed in Taiwan.
