Abstract

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.
