双孔鱼科(Gyrinocheilidae)鱼类的系统发育和分类位置
PHYLOGENETIC RELATIONSHIP AND SYSTEMATIC POSITION OF GYRINOCHEILUS (GYRINOCHEILIDAE, PISCES)
【摘要】 <正> 双孔鱼属(Gyrinocheilus)是Vaillant(1902)根据婆罗州双孔鱼(G.pustulosus)而创立的,共有三个种,主要分布于南亚。只有双孔鱼G.aymonieri(Tirant)一种产于我国西双版纳澜沧江水系。关于双孔鱼科的分类位置以及在鲤亚目中系统发育上的关系,各学者尚有不同的意见。如Vaillant认为是平鳍鳅科的一个属.而Regan(1911)认为应归鲤科而且应放在墨头鱼属(Garra)及缨唇鱼属(Crossocheilus)之后。也有人将该属放在鲤科内另立一亚科——双孔鱼亚科(Gyrinocheilinae)(Weber and de Beaufort 1906)。以后Hora(1923)又将它提升为双孔鱼科(Gyrinocheilidae)并认为与鲤科近缘,这个观点为以后多数学者所采用,一般认为它比鲤科更为特化(Berg 1947;Greenwood et al.1966;Rass and Lindberg 1971)。
【Abstract】 Two specimens of Gyrinocheilus aymonieri have been osteologically investigatedto compare with the results of the previous study by the Indian author. More thanten morphologieal characteristics .of Gyrinocheilus have been compared with thecorresponding ones in family Catostomidae in order to elueidate the relationship ofphylogeny. Five characteristic are recognized as symplesiomorphs, one as synapo-morph, and another one as apomorph. The authors thus consider that Gyrinocheilidaeis.a monophyletic family and forms with the family Catostomidae a sister group. Thefamily Gyrinocheilidae seems to be more advanced in systematic position than thefamily Catostomidae because of its being provided with more adaptative mechanismsand of the recency of branching forth from the .common ancestor.
