摘要
几十年来,人们一直在对田蟹的系统发育进行深入讨论。在此关头,本文重新评估了栖息在切拉里村(印度喀拉拉邦)稻田中的一种食用田蟹的 "几十年前 "的系统发育状况,这种田蟹迄今被称为 Paratelphusa hydrodromous。在阿尔科克(1910 年)的描述之后,几乎没有人认真尝试过确定其确切的分类地位。通过综合使用解析分析和分子方法,本研究揭示了候选形式(物种)与 Oziotelphusa 属更近的亲缘关系。biloba, O. wagrakarowensis, O. kerala and O. aurantia)的形态学和分子特征进行比较,结果表明候选形式在分类学上是一个独特的实体,有资格被视为一个未报告的物种;其建议的修订命名法为 Oziotelphusa chelarensis,让人联想到村庄 Chelari。此外,本文还从保护角度探讨了这一分类研究的意义。
Revisiting the phylogenetic status of a field crab (Decapoda, Brachyura) from Chelari, Malappuram District (Kerala, India): an integrative approach through morphological and molecular taxonomy
The phylogeny of field crabs has been under profuse discussion for several decades. At this juncture, this paper reassesses the “decades old” phylogenetic status of an edible field crab, hitherto referred to as Paratelphusa hydrodromous, inhabiting the paddy fields of Chelari village (Kerala, India). After Alcock’s (1910) description, there has hardly been any serious attempt at ascertaining its precise taxonomic status. Through an integrated approach, using parsimony analysis and molecular methods, the present study reveals the candidate form’s (species’) closer affinity to the genus Oziotelphusa. Comparison of morphological and molecular characteristics with its closest phylogenetic neighbours (O. biloba, O. wagrakarowensis, O. kerala and O. aurantia) has shown that the candidate form is a taxonomically distinct entity, qualified to be considered as an unreported species; its suggested revised nomenclature is Oziotelphusa chelarensis, reminiscent of the village Chelari. Further, the paper views the relevance of this taxonomic study from conservational angles as well.
