Richard Sexton's site on killies breaks the Fundulus up into five sub-genus.
In the sub-genus Zygonectes is included auroguttatus, blairae, chrysotus,
cingulatus, dispar, escambiae, euryzonus, jenkinsi, luciae, notatus, nottii,
olivaceus, rubrifons, sciadicus.

Both jenkinsi and sciadicus are included.

Huber's Killi-Data 2000 tends to agree but includes lineolatus in the
grouping. (p. 327-8)

Kenneth Lazara in the Killifish Master Index c. 2000 includes the same
species as Huber in the Zygonectes Agassiz 1854, Wiley 1986 group, except
that he considers auroguttatus a junior sysnonym of cingulatus.

Except that those sources feel that those fishes are fairly closely related,
I don't know the nuances of the grouping. If it wasn't for B.G.'s contest, I
probably would have been stuck "doing something useful" = a honey do or two.

All the best!
