Abstract

The endemic terrestrial Crown Snail from Southern Thailand formerly in Macrochlamys Gray, 1847 is now described as Taphrenalla Pholyotha & Panha gen. nov., based on comparative morphology and molecular data. Overall, eleven Taphrenalla species are now recognized, including two nominal species: T. asamurai and T. diadema. A total of nine new species are proposed: T. alba sp. nov., T. conformis sp. nov., T. corona sp. nov., T. dalli sp. nov., T. incilis sp. nov., T. macrosulcata sp. nov., T. parversa sp. nov., T. pygmaea sp. nov. and T. zemia sp. nov. The molecular phylogeny constructed from the mitochondrial cytochrome oxidase c subunit I (COI) and 16S rRNA gene fragments plus the nuclear 28S rDNA gene fragments revealed that Taphrenalla gen. nov. is monophyletic with a well-supported clade. The diagnostic characters of Taphrenalla gen. nov. are the shell sculpture with several radial grooves, body with well-developed colourful stripes running from the head to tail, and genitalia similar to Macrochamys but with an un-coiling epiphallic caecum. The spermatophore has one or two spines near the sperm sac and a spineless tail.

综合系统学研究发现泰国陆蜗牛属(Taphrenalla)及9个新种

原产于泰国南部Macrochlamys Gray, 1847年的特有陆地冠螺，根据比较形态学和分子数据，现在被描述为Taphrenalla Pholyotha & Panha gen. nov.。总的来说，现在已经确认了11种taprenalla，包括两个名义种:T. asamurai和T. diadema。总共提出了九个新物种:t·阿尔巴sp. 11月,t . conformis sp. 11月,t .电晕sp. 11月,t·达利sp. 11月,t . incilis sp. 11月,t . macrosulcata sp. 11月,t . parversa sp. 11月,t . pygmaea sp. 11月和t . zemia sp. 11月的分子系统学由线粒体细胞色素c氧化酶亚基我(COI)和16 s rRNA基因片段+核28 s rDNA基因片段显示,Taphrenalla 11月是单源的将军支持进化枝。该虫的诊断特征为:甲壳上有若干放射状凹槽，体表从头部到尾部有发育良好的彩色条纹，生殖器与巨足虫相似，但有一个未卷曲的外阴部盲肠。精子包囊附近有一到两个刺和一条无刺的尾巴。
