Abstract

ABSTRACT The Euconulidae is a globally distributed land snail family but there is no record of this family from Thailand. In this study, we describe a new genus, Siamoconus gen. nov., based on comparative studies of the shell characteristics, external morphology of animals, radula, genital and spermatophore structures, and molecular phylogeny. We performed phylogenetic analyses of two mitochondrial gene fragment (cytochrome c oxidase I, COI; and 16S rRNA) and one nuclear (28S rRNA) gene fragment to clarify the relationships with other euconulid genera and its position in the superfamily Trochomorphoidea. We also analysed shell morphometrics, male genitalia and mantle pigmentation of Siamoconus gen. nov., confirming the status of three new species with keeled shells (S. boreas sp. nov., S. coleus sp. nov. and S. geotrochoides sp. nov.) and one new species with a rounded shell (S. destitutus sp. nov.). These new species are restricted to limestone areas in northern and north-eastern Thailand. We also re-examined the status of other genera in the superfamily Trochomorphoidea based on shell features, body pigmentation, radula, genital anatomy, spermatophore morphology, and a phylogenetic analysis of all available trochomorphoidean DNA sequences. Our analysis suggests that the family Geotrochidae, previously synonymised with the Trochomorphidae, should be resurrected to represent the genus Geotrochus from Borneo, and this family is retrieved as the sister clade of the Dyakiidae.

泰国真螺科蜗牛的分子系统发育及其在巨螺总科中的地位(柱头科:巨螺总科)及一新属的描述

陆蜗牛科(Euconulidae)是一种分布于全球的陆地蜗牛科，但在泰国尚无该科的记录。本文通过对其外壳特征、外部形态、radula、生殖器和精包结构以及分子系统发育的比较研究，描述了一个新属Siamoconus gen. nov.。我们对两个线粒体基因片段(细胞色素c氧化酶I, COI;和16S rRNA)和一个核(28S rRNA)基因片段，以澄清与其他真核属的关系及其在Trochomorphoidea超家族中的位置。我们还对Siamoconus gen. nov.的壳形态、雄性生殖器和地幔色素进行了分析，确定了3个龙骨壳新种(S. boreas sp. nov.、S. coleus sp. nov.和S. geotrochoides sp. nov.)和1个圆壳新种(S. tus sp. nov.)的地位。这些新物种仅限于泰国北部和东北部的石灰岩地区。我们还根据外壳特征、身体色素沉着、radula、生殖器解剖、精包形态以及所有可用的trochomorphoidean DNA序列的系统发育分析，重新检查了Trochomorphoidea超家族中其他属的地位。我们的分析表明，以前与Trochomorphidae同义的Geotrochidae科应该被复活来代表婆罗洲的geotrochchus属，并且该科作为Dyakiidae的姐妹分支被检索。ZooBank: urn: lsid zoobank.org:酒吧:c5205f4e - 5 - dde - 42 - e6 a532 - 761 cafe099c3

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
