摘要
描述分布于浙江省武义县武义江的吻虾虎鱼1新种,定名为武义吻虾虎鱼(Rhinogobius wuyiensis)。该虾虎鱼在头部斑纹上与雀斑吻虾虎鱼(R.lentiginis)相近,但有如下特征可区别于相近种:具眼肩胛骨管及前鳃盖管(vs.无任何感觉管孔);椎骨数10+16=26(vs.27);臀鳍分支鳍条7-9(vs.6-7);头部斑点大小不等且不规则,常呈线状交织(vs.具规则的小圆斑);鳃盖条部内侧无斑点(vs.密布小点)。
A new freshwater goby, Rhinogobius wuyiensis sp. nov., was found in the Wuyi river （28°51′N, 119°46′E） in Zhejiang Province, China. The spot pattern on the head of this species was similar to R. lentiginis, but differed from this species in a number of ways： head had cephalic lateralis canals （vs. without cephalic lateralis canals）; vertebral count 10＋16=26 （vs. 27 ） ; anal fin has 7-9 branched fin-rays （vs. 6-7 ） ; head had an irregular spot pattern which were joined together （vs. with regular dots） ; inner branchiostegal memberane without dots in male （ vs. with many dots）.
