The poorly studied leatherleaf slug genus in Thailand was carefully investigated. Members of this genus are phenotypically similar, making their identification very challenging. This study clarifies the taxonomic status of all species in Thailand by combining morphological and anatomical studies with DNA barcoding. Monophyly of all species was confirmed by analysis of the mitochondrial COI data and that all species have the acropleurocaulis type of penis. Currently, three species are recognised: , Mitchueachart & Panha, , and Mitchueachart & Panha, that are new to science. For distinct characteristics, is characterised by having a cylindrical penis and honeycomb-like glans, has a lanceolate penis with half honeycomb-like glans, and has a cylindrical penis with wavy-like glans. In addition, more detailed descriptions of the radula and genitalia of all three species and their distribution are also carefully presented, enhancing the understanding of this leatherleaf slug genus in Thailand.
对泰国研究较少的皮叶蛞蝓属进行了仔细调查。该属成员在表型上相似，这使得它们的鉴定极具挑战性。本研究通过将形态学和解剖学研究与DNA条形码相结合，阐明了泰国所有物种的分类地位。通过对线粒体COI数据的分析证实了所有物种的单系性，并且所有物种都具有阴茎顶侧茎类型。目前，已识别出三个物种：Mitchueachart & Panha于2019年发现的新物种，以及Mitchueachart & Panha于2020年发现的新物种。就独特特征而言，的特征是具有圆柱形阴茎和蜂窝状龟头，具有披针形阴茎和半蜂窝状龟头，而具有圆柱形阴茎和波浪状龟头。此外，还仔细介绍了这三个物种的齿舌和生殖器的更详细描述及其分布，增进了对泰国这种皮叶蛞蝓属的了解。
