"Distinguished from all other Lebias
by the following combination of characters: lower
jaw sharply upturned, nearly perpendicular
to body axis, a condition present among congeners
only in L. splendens; teeth conical rather
than tricuspid as in all Lebias species except L.
asquamatus; cephalic neuromast system open,
not in closed canals as in the L. dispar/L. fasciatus
group; interarcual cartilage absent versus
present in all congeners except L. asquamatus;
pectoral fins obliquely set rather than horizontal
as in all congeners; large size, approaching
91 mm TL versus maximum body size of 70 mm
TL for cogeners (the syntopic population of L.
dispar approaches a maximum of 47 mm TL)."

New and not as of yet described species known only by their collection and locality data; that is, the best we can do is refer to them as, for example: "Pachypanchax species Betsiboka" which would mean "the Pachypanchax (probably! no guarantees!) species that is from Betsiboka".
