Description
Summary:A new nematode species in the order Mononchida, Miconchus prokini sp. nov., found in Lake El'gygytgyn (Chukotka, Russia) is described and illustrated. The new species is the largest member of the genus known to date. It is morphologically close to Miconchus rex in the big body size, vulva position in females, the number of precloacal supplements in males and in the relative length of the pharynx in both sexes, but it has a longer body (L = 7.7–13.1 mm in M. prokini vs. L = 6.5–7.0 mm in M. rex) and spicules (225–252 µm in M. prokini vs. 180 µm in M. rex), and a shorter tail (c = 9.3–15.2 in M. prokini vs. c = 5.3–7.1 in M. rex).
