Abstract

Background: The family Proalidae Harring & Myers, 1924, includes four genera and 53 species, distributed across all eight biogeographic realms and inhabiting various environments, including freshwater, saltwater and terrestrial environments. The genus Proales, the largest within Proalidae, encompasses 41 species characterised by diverse morphological traits. In Korea, the presence of Proalidae has been documented with five known species: Bryceellaperpusilla Wilts, Martínez Arbizu & Ahlrichs, 2010, B.stylata (Milne, 1886), B.tenella (Bryce, 1897), Proalesfallaciosa Wulfert, 1937 and Proalinopsiscaudatus (Collins, 1872).

New information: A new species, Proalesamplus sp. nov., is the 42nd species within the genus Proales. This species exhibits unique morphological characteristics in the trophi, particularly in the epipharynx, which are distinctive enough to prevent misidentification with other Proales species. The habitus of the new species bears some resemblance to P.phaeopis Myers, 1933, sharing features, such as an elongated and fusiform body, two eyespots, a single foot pseudosegment, two short toes and the absence of a dorsal papilla between the toes. However, the epipharynx of the two species is markedly different. The unique epipharynx characteristic of this new species is unparalleled within the genus Proales.

Proalesamplus sp. nov., a new monogonont rotifer with a large epipharynx from Korea (Rotifera, Proalidae).
背景:海鹦科(Proalidae Harring & Myers,1924 年)包括 4 属 53 种,分布于所有 8 个生物地理区域,栖息于各种环境中,包括淡水、海水和陆地环境。Proales属是Proalidae中最大的属,共有41个种,形态特征各不相同。在韩国,有 5 个已知物种被记录在案:Bryceellaperpusilla Wilts, Martínez Arbizu & Ahlrichs, 2010, B.stylata (Milne, 1886), B.tenella (Bryce, 1897), Proalesfallaciosa Wulfert, 1937 和 Proalinopsiscaudatus (Collins, 1872):新资料:新种 Proalesamplus sp.该种在滋养体,特别是在会咽部表现出独特的形态特征,这些特征足以防止与其他 Proales 种的错误识别。该新种的习性与 P.phaeopis Myers, 1933 有一些相似之处,如身体拉长呈纺锤形、有两个眼点、有一个单足假节、有两个短趾以及趾间没有背乳头。然而,这两个物种的会咽却明显不同。这一新物种独特的会咽部特征在 Proales 属中是绝无仅有的。

期刊介绍: Biodiversity Data Journal (BDJ) is a community peer-reviewed, open-access, comprehensive online platform, designed to accelerate publishing, dissemination and sharing of biodiversity-related data of any kind. All structural elements of the articles – text, morphological descriptions, occurrences, data tables, etc. – will be treated and stored as DATA, in accordance with the Data Publishing Policies and Guidelines of Pensoft Publishers. The journal will publish papers in biodiversity science containing taxonomic, floristic/faunistic, morphological, genomic, phylogenetic, ecological or environmental data on any taxon of any geological age from any part of the world with no lower or upper limit to manuscript size.
