Abstract

A preliminary molecular phylogenetic framework for 12 genera (23 species) of the family Parabathynellidae from Europe, Australia, North Africa and India is presented based on mitochondrial and nuclear markers (Cox1 and 18S). The generated hypothesis places the Southeast Asia genus Paraeobathynella closer to European genera (Iberobathynella, Paraiberobathynella and Parabathynella) than to the Australian (Brevisomabathynella, Atopobathynella, Billibathynella, Octobathynella, Arkaroolabathynella and Lockyerenella) or Indian genera (Habrobathynella), or to the cosmopolitan genus Hexabathynella (Spain and Australia). Three new species of the genus Paraeobathynella from Thailand, P. ratensis n. sp., P. siamensis n. sp. and P. hanjavanitiana n. sp., are described based on morphological and molecular features. This is the first record of the genus from Thailand and extends its range of distribution within Asia, where it was previously known only from Vietnam. The new species are clearly separated as independent units at least since the Middle Miocene.

泰国洞穴中Parabathynellidae（甲壳纲，Bathynellacea）和三个新种的分子系统发育

本文基于线粒体和核标记(Cox1和18S)，初步建立了来自欧洲、澳大利亚、北非和印度的拟拟拟菜科(Parabathynellidae) 12属(23种)的分子系统发育框架。所产生的假设认为，东南亚的Paraeobathynella属更接近欧洲属(Iberobathynella, Paraiberobathynella和Parabathynella)，而不是澳大利亚属(Brevisomabathynella, Atopobathynella, Billibathynella, Octobathynella, Arkaroolabathynella和Lockyerenella)或印度属(Habrobathynella)，或世界范围内的Hexabathynella属(西班牙和澳大利亚)。本文根据形态和分子特征，描述了泰国拟鸟属(Paraeobathynella) 3个新种:P. ratensis n. sp.、P. siamensis n. sp.和P. hanjavanitiana n. sp.。这是该属在泰国的首次记录，并扩大了其在亚洲的分布范围，在亚洲，它以前只在越南被发现。至少从中新世中期开始，这些新物种就被清楚地划分为独立的单位。

期刊介绍： Contributions to Zoology solicits high-quality papers in all systematics-related branches of comparative zoology (including paleozoology). Preference will be given to manuscripts dealing with conceptual issues and to integrative papers (e.g., ecology and biodiversity, morphology and phylogeny and character state evolution, phylogeny and historical biogeography, systematics and bioinformatics, bioinformatics and biodiversity, habitat disturbance and biogeography, etc.). Reviews and alpha-taxonomic contributions are considered for publication, but acceptance will depend on their high quality and exceptional nature.
