In this study, two species belonging to the genus Eutyphoeus Michaelsen, 1900, and the rare monotypic genus Priodoscolex Gates, 1940, are described based on collections deposited in the National Zoological Collections, General Non-Chordata Section, Zoological Survey of India, Kolkata. Eutyphoeus unithecus Ahmed & Marimuthu, sp. nov. is characterized by a single, mid-ventral spermathecal pore in the intersegmental furrow 7/8 and a single associated spermatheca. The monotypic genus Priodoscolex is known from its type locality in the Nandi Hills of Karnataka, southern India. A new species, Priodoscolex maduraiensis Ahmed & Marimuthu, sp. nov., is described here, which is characterized by the presence of three pairs of spermathecal pores on segments 7, 8 and 9. The diagnostic features of the new species are discussed and illustrated.
在本研究中，基于保存在印度动物调查局加尔各答总无脊椎动物学部国家动物标本馆的标本，描述了1900年的Eutyphoeus Michaelsen属的两个物种以及1940年罕见的单型属Priodoscolex Gates。新种艾哈迈德氏真盲蚓（Eutyphoeus unithecus Ahmed & Marimuthu）的特征是在第7/8节间沟中有一个单一的腹中线受精囊孔和一个相关的受精囊。单型属Priodoscolex已知于其在印度南部卡纳塔克邦南迪山的模式产地。本文描述了一个新种，马杜赖氏原盲蚓（Priodoscolex maduraiensis Ahmed & Marimuthu），其特征是在第7、8和9节上有三对受精囊孔。讨论并说明了新种的诊断特征。
