Reproductive system of Dorylaimopsis nodderi

The genus has cosmopolitan distribution meaning it can be found worldwide.^[1] There are currently seven species that inhabit the sea of China (D. boucheri, D. heteroapophysis, D. jinmendaoica, D. longispicula, D. papilla, D. rabalaisi and D. turneri). The Yellow Sea currently contains two species, D. sinica and D. zhangi.^[2] This genus was also abundant in the Gulf of Mexico along with Sabatieria, Pselionema, Tricoma, and Halalaimus.^[3]

They are common, often the dominant nematodes fauna, inhabitants of muddy intertidal and subtidal sediments.^[2]

Taxonomy

The genus is a chromadorid nematode of the order Araeolaimida. It is more specifically a member of the family Comesomatidae.^[1]

There are several synonymized names under this genus. They are Mesonchium, Pepsonema and Xinema.^[4] The species D. metatypica Chitwood, 1936 is most likely a member of the genus Hopperia due to its lateral differentiation that consists of larger, irregularly-distributed coarse dots as in Hopperia. It has been place in that genus by several studies (see: Hopperia metatypica).^[2]^[5]
