叶鰕虎鱼广泛分布于热带水域,生活于珊瑚丛中。1977年春,在西沙群岛珊瑚丛中采得叶鰕虎鱼数十尾,经研究其中有2新种,分别定名为眼带叶鰕虎鱼Gobiodon oculolineatus Wu sp.nov.和多线叶鰕虎鱼Gobiodon multilineatus Wu sp.nov.其模式标本均存于厦门水产学院鱼类研究室。现分述如下。
This paper presents two new species of Gobiodon fishes,which were collected from the Xisha Islands of South China Sea in April,1977.The holotypes are all kept in the laboratory of fishes,Xiamen Fisheries College,Fujian,China.The description of the two new species is as follows.Gobiodon oculolineatus Wu sp.nov.(Figure 1)D.VI-I-10;A.I-9;P.17-18;V.I-5;C.18-20.Gill-rakers 0-1+8-9.Depth 2.6-3.0 in length,head 2.7-3.3.Snout 3.0-4.2 in head,eye 3.0-4.4.The new species differs from all known species of Gobiodon in having two bluish transverse lines originated below the eyes,the coloration between these lines is dark reddish brown;colour of head differs from the body,reddish brown on head,dusky brown on body.The new species has no bands and spots on sides.Holotype No.A010692,length without caudal 24 mm,collected from Yongxing Island,Xisha Islands,April 21,1977.Paratypes 6:Nos.A010693-A010695,length 20-20.5 mm,collected with the holotype specimen.Nos.S01477(1)-S01477(3),length 18-20mm,collected from Shidao Island,April 24,1977.Gobiodon multilineatus Wu sp.nov.(Figure 2)D.VI-I-10;A.I-9;P.18-19;V.I-5;C.20-21.Gill-rakers 0-2+6-7.Depth 2.6-3.3 in length,head 3.0-3.6.Snout 3.4-4.2 in head,eye 3.4-4.4.The body of new species yellowish brown,4-6 bluish transverse lines on head,first and second lines from the back of the head through the eye to below the head,the coloration between these lines being dark reddish brown.Along the sides of body 10-20 bluish transverse lines descend from the back towards the belly.The present species resembles Gobiodon quinquestrigatus(Cuv.et Val.)in having transverse lines on head,but differs from the latter in having more cross lines on the sides of body.Holotype No.A010688,length without caudal 22mm,collected from Shidao Island,April 21,1977.Paratypes 6:Nos.A010689-A010691,length 22-27mm,collected with the holotype specimen.Nos.S01379(1)-S01379(3),length 18-22mm,collected from Yongxing Island,April 13,1977.
