记述了日本北方北海道近海深海中发现的一种自由生活的海洋线虫，属Micoletzkyia Ditlevsen，1926（Micoletzkyia Ditlevsen，1927）。与M. mawatarii sp. nov.相似。magna Vitiello，1970和M. longispicula Huang and Cheng，2012在尾和引带的形状上与前者不同，但在体宽和头刚毛的长度上与前者不同，在体长、尾的比例长度、神经环的位置和前唇突的形状上与后者不同。Micoletzkyia mawatarii sp. nov. paregeleans Allgen，1954，在其庞大的身体尺寸，但不同于它的食道长度，形状的引带，大小和位置的前肠补充，并在有一个较长的尾巴。
A new species of free-living marine nematode, belonging to the genus Micoletzkyia Ditlevsen, 1926 (Phanodermatidae Filipjev, 1927), is described from the deep sea off the coast of Hokkaido, northern Japan. Micoletzkyia mawatarii sp. nov. resembles M. magna Vitiello, 1970 and M. longispicula Huang and Cheng, 2012 in the shape of the tail and gubernaculum, but differs from the former in body width and in length of the cephalic setae, and from the latter in body length, proportional length of the tail, position of the nerve ring, and shape of the precloacal supplement. Micoletzkyia mawatarii sp. nov. also resembles M. parelegans Allgen, 1954 in its large body size, but differs from it in esophagus length, shape of the gubernaculum, size and position of the precloacal supplement, and in having a longer tail.
