Shidlovskiy, K. M., B. R. Watters & R. H. Wildekamp. 2010. Notes on
the annual killifish species Nothobranchius rachovii
(Cyprinodontiformes; Nothobranchiidae) with the description of
two new species. Zootaxa, 2724: 37–57.
Abstract:
Two new species of the East African annual killifish genus Nothobranchius,
N. krysanovi and N. pienaari, occurring on the coastal plains of
Mozambique and in the Republic of South Africa, are described. Both are
members of a clade, herein termed as N. rachovii species group, within the
subgenus Nothobranchius. The species N. rachovii is rediagnosed on the
basis of cytology, mtDNA analyses, morphology and male colouration.
Both new species, N. krysanovi and N. pienaari, can be distinguished from
the other species of the group by male colouration, morphology, cytology
and mtDNA sequences. Based on mtDNA analyses the subgenus
Zononothobranchius is reviewed and presently regarded as containing
only one species.
Morphology similar to Nothobranchius rachovii and N. krysanovi but
distinguished from those by a slightly deeper body in males (Ref. 85866).
Nothobranchius pienaari is distinguished from other species of the genus
by the following combination og characters: male with colouration
consisting of alternating blue-green to grey-green and dark red-brown to
almost black scale margins and oblique bars on body and dorsal and anal
fins, dark brown spotted basal half of caudal fin, and orange subterminal
and black terminal band
