The genus is named for Prof. Patrick Martin (Royal Belgian Institute of Natural Sciences), whose persistent efforts on behalf of obscure, intractable, deep-lake oligochaetes has provided much insight to lumbriculid systematics. The specific epithet refers to its general distribution within North Carolina.

First pair of nephridia on 6/7. Nephridia absent in VIII–XII, usually paired in XIII, and occurring irregularly in posterior segments. Each nephridium with small anteseptal funnel, a granular postseptal expansion 50–120 μm long by 30–50 μm wide, and a convoluted duct that may pass through several anterior or posterior segments ventral to the gut, usually terminating in a narrow vesicle (up to 85 μm long by 24 μm wide) at the nephropore (

Main dorsal and ventral blood vessels prominent, without secondary longitudinal vessels. Dorsal vessel separate from gut through about XV, connected to perivisceral sinus by short blood vessels; closely appressed to gut posterior to XV, eventually becoming indistinguishable from perivisceral sinus in most specimens. Circum-pharyngeal trunks join in V or at 4/5 to form the ventral vessel. One pair of commissural blood vessels in II–X; they are prominent and convoluted in II–VII, but shorter and difficult to see in IX–X. Perivisceral sinus begins in about VI; chloragogen begins in about VII. Starting near XXX, the dorsal vessel appears nodulate (

I). Prostate cells usually very granular and often indistinct; up to 30 cells in the largest bundles, but usually fewer. Transition between the ampulla and duct is gradual; duct has thinner muscle layer (2 μm), and lacks prostates. Ectally, the duct terminates in a slightly thickened penial structure 30–50 μm high. The penial structure has somewhat elongated cells, forming a distinct papilla in most specimens (

The unusual common duct joining the vasa deferentia to the atrium is thin and difficult to observe. In most cases it is histologically distinct from the vasa deferentia in its narrow and irregular form, the apparent lack of cilia, and the thin muscle coat. However, these characters all vary, and cilia appear to be present in at least one specimen.
