Material Examined. MNP17-1117-45A14 , Shirui Kashong (Peak), Shiroi National Park , Manipur, Lat/Lon: 25.1302, 94.4202, elevation: 2106.19 m, collected on October 11, 2017, by Shweta Yadav GoogleMaps .

Description ( Fig. 4 View FIGURE 4 ). A phylogenetic analysis was performed on a single, malformed specimen. It was not feasible to enumerate the taxonomic components in a methodical manner. The clitellum extends from xiii–xvii. The female pore single, median on xiv, within a small white circular patch. The male genital region is somewhat similar to P. bainii Stephenson, 1915 , and the male pores are on xviii. With only a few characters observed, it was difficult to identify the specimen up to species level. Nevertheless, we have included the specimen in the study to provide a genomic signature for further investigation.

DNA barcode. The mitochondrial COI sequences obtained from samples MNP17-1117-45A14 and MNP17- 1118-45A15, with process IDs IEW1071-17 and IEW1072-17, respectively, have been assigned the BIN number BOLD: ADL0399. The newly identified species shares an 87.86% identity match with Perionyx rufulus Gates 1945 , represented by accession number MT431999 View Materials .

The sequences of all three species examined in the study exhibit an approximate 87% identity match with Perionyx rufulus . This predicament was caused by a lack of molecular COI data for the genus Perionyx in the database. Only the COI sequence of Perionyx excavatus is available in NCBI, and the remaining sequences of Perionyx gravelyi ( Stephenson 1917) remain unverified. Additionally, there exist unpublished records of Perionyx depressus Stephenson 1914 , Perionyx rufulus Gates 1945 and Perionyx sansibaricus ( Michaelsen 1891) .
