Some Wonderful New Nematodes Nematodes are diverse and numerous, and the few tens of thousands of species that are known to science are surely just a small sample of all the species that are out there. Thus it is fitting that this special issue of Annales Zoologici introduces 21 new species to the world. This species is described from 13 females that were collected from the Latka River. They were found in the bottom sediments about half a meter deep. There is only one other species known from this genus, described in 1995.
Nematodes are all rather similar to the naked eye.
Their success has apparently not been dependent on a wide variety of shapes, bright colors, or or strange morphological additions. This species is named for the locality in Sri Lanka of the Tea Research Institute where this nematode was found. This last character, though, is striking. It distinguishes this species from the very-similar African genus Martadamsonius and the Indian genus Raonema . It refers to the fact that females of Hekarella have only one ovary.
