The study introduces a new species, Perionyx browantlerus Tiwari & Yadav sp. nov. identified in the north-eastern region of India, particularly in Manipur State. It possesses two pairs of mid-ventral spermathecal pores located in the intersegmental furrow of segments vii/viii/ix, possessing a vestigial gizzard, exhibiting holandric traits, and lacking pineal setae. Perionyx browantlerus Tiwari & Yadav sp. nov. stands out from other similar species because of its adiverticulate spermathecae. Furthermore, another interesting species Perionyx sp. nov.? 1 was also found, which is characterized by a unique "V"-shaped longitudinal oblong impression situated above the male pore, which extends from each papilla. Unfortunately, the single specimen with malformed segmentation prevents it from being described as a new species.
该研究介绍了一种新物种，即印度东北部地区（特别是曼尼普尔邦）发现的布朗特角环毛蚓（Perionyx browantlerus Tiwari & Yadav sp. nov.）。它有两对位于第七/八/九节间沟的腹中线受精囊孔，有一个退化的砂囊，表现出雄体特征，且没有松果体刚毛。布朗特角环毛蚓（Perionyx browantlerus Tiwari & Yadav sp. nov.）因其无憩室的受精囊而与其他类似物种不同。此外，还发现了另一个有趣的新物种环毛蚓（Perionyx sp. nov.? 1），其特征是在雄孔上方有一个独特的“V”形纵向长方形压痕，从每个乳突延伸出来。不幸的是，唯一一只节段畸形的标本使其无法被描述为一个新物种。
