A new goby species Tridentiger radiatus sp. nov. is described from Zhuhai, Guangdong Province of China. The new species, found in sympatry with a widely distributed barbeled congener Tridentiger barbatus (Günther, 1861), is one of the only two Tridentiger species known to possess mandibular and cheek barbels. Tridentiger radiatus is diagnosed by having higher longitudinal and transverse scale counts, less developed barbels, unmottled colouration compared to T barbatus, and 3 dusky radiating infraorbital bands. Partial 12s rDNA sequence data obtained from 5 individuals of T radiatus and 2 individuals of T. barbatus, together with published sequence data of other congeners confirmed validity of the new species. The divergence between T. radiatus and T. barbatus well exceeds the divergence of other sister taxa in the same genus. Monophyly of the two barbeled species is supported.
在中国广东省珠海市发现了一种新的虾虎鱼物种——辐纹纹缟虾虎鱼（Tridentiger radiatus sp. nov.）。该新物种与广泛分布的长须同属物种李氏纹缟虾虎鱼（Tridentiger barbatus (Günther, 1861)）同域分布，是已知仅有的两种具有下颌须和颊须的纹缟虾虎鱼物种之一。辐纹纹缟虾虎鱼的特征为纵列鳞和横行鳞数量更多、触须发育程度较低、与李氏纹缟虾虎鱼相比体色无斑点，以及有3条暗色辐射状眶下带。从5条辐纹纹缟虾虎鱼个体和2条李氏纹缟虾虎鱼个体获得的部分12s rDNA序列数据，以及其他同属物种已发表的序列数据，证实了该新物种的有效性。辐纹纹缟虾虎鱼与李氏纹缟虾虎鱼之间的差异远超同一属中其他姊妹类群之间的差异。支持这两种长须物种的单系性。
