Dictyostelid cellular slime molds (dictyostelids) are common inhabitants of the soil and leaf litter layer of fields and forests, along with animal dung, where they feed mostly on bacteria. However, reports on the species diversity of dictyostelids in South Asia, particularly Thailand, are limited. The research reported in this paper was carried out to increase our knowledge of the species diversity of this group of organisms in northern Thailand.
Forty soil samples were collected at four localities in northern Thailand to assess the species richness of dictyostelids. These samples yielded five dictyostelid isolates that were not morphologically consistent with any described species. Based on molecular signatures, all five of these isolates were assigned to the family Cavenderiaceae, genus Cavenderia. All five share a number of morphological similarities with other known species from this family. The new taxa differ from previously described species primarily in the size and complexity of their fruiting bodies (sorocarps). This paper describes these new species (Cavenderia aureostabilis, C. bhumiboliana, C. protodigitata, C. pseudoaureostipes, and C. subdiscoidea) based on a combination of morphological characteristics and their phylogenetic positions.
At least 15 taxa of dictyostelids were obtained from the four localities in northern Thailand, which indicates the high level of species diversity in this region. Five species were found to be new to science. These belong to the family Cavenderiaceae, genus Cavenderia, and were described based on both morphology and phylogeny.
粘菌目细胞黏菌（粘菌）是田野和森林土壤及落叶层以及动物粪便中的常见居民，主要以细菌为食。然而，有关南亚（尤其是泰国）粘菌物种多样性的报道有限。本研究旨在增加我们对泰国北部该类生物物种多样性的了解。
从泰国北部四个地点采集了 40 个土壤样本，以评估粘菌的物种丰富度。这些样本共分离出 5 株粘菌，其形态与任何已描述的物种都不一致。基于分子特征，这 5 株菌均被归为 Cavenderiaceae 科，Cavenderia 属。这 5 株菌与该科的其他已知种在许多形态上具有相似性。新分类群与先前描述的种主要在子实体（果实体）的大小和复杂性上有所不同。本文根据形态特征和系统发育位置，描述了这 5 个新种（Cavenderia aureostabilis、C. bhumiboliana、C. protodigitata、C. pseudoaureostipes 和 C. subdiscoidea）。
从泰国北部的四个地点共获得了至少 15 种粘菌，这表明该地区的物种多样性水平很高。有 5 个种被发现是新的科学发现。它们属于 Cavenderiaceae 科，Cavenderia 属，是根据形态和系统发育而描述的。
