Abstract

A systematic study of the coastal Athetini monotypic genus Pseudothinusa Tasaku and Maruyama is presented using morphological and molecular characters. Detailed examination of the voucher specimens of P. sunahama Tasaku and Maruyama revealed that they represent a species of Adota Casey based on the following combination of characters: body surface with isodiametric microsculpture; antennomere 2 longer than 3; medial lamellae of internal sac of median lobe of aedeagus reduced; spermathecal duct coiled once distally. The proposed synonymy of Pseudothinusa under Adota was also supported by gene tree criterion (PA, BA, and ML trees) using partial COI and 28S gene sequences. This new synonymy (Adota Casey, 1910 = Pseudothinusa Tasaku and Maruyama, 2023, new syn.) necessitates the following new combination: Adota sunahama (Tasaku and Maruyama), new comb. We also provide scanning electron microscopy (SEM) micrographs for their diagnostic characters. A checklist of Adota from the world and a key to species of Adota are presented.

基于形态学和分子证据的海洋滨海拟藻的系统位置（鞘翅目：拟藻科：拟藻科）

本文从形态学和分子生物学的角度，系统地研究了沿海鸭茅属（Pseudothinusa Tasaku）和丸山（Maruyama）。对P. sunahama Tasaku和Maruyama的代金券标本的详细检查显示，它们基于以下特征组合代表了Adota Casey的一个物种：体表具有等径微雕刻；天线粒2大于3；鹰嘴蝶正中叶内囊内侧小叶缩小；精囊管卷曲一次远端。采用部分COI和28S基因序列的基因树标准（PA、BA和ML树）也支持了Pseudothinusa在Adota下的同义性。这个新同义词（Adota Casey, 1910 = Pseudothinusa Tasaku and Maruyama, 2023，新同义词）需要以下新组合：Adota sunahama (Tasaku and Maruyama)，新梳子。我们还提供了扫描电子显微镜（SEM）显微照片，以了解其诊断特征。介绍了世界上的阿多塔的清单和阿多塔物种的关键。
