Abstract—The osteology of Florenciella lugubris is described. F. lugubris is attributed to the family
Epigonidae on the basis of specific characters of structure of orbital bones, skull, jaws and hyoid, presence of
three principal spines on operculum, contact of pterygiophores of dorsal fins, 10 + 15 vertebrae, extension of
the lateral line onto the caudal fin, structure of the first hemapophysis and interhaemale, caudal skeleton, etc.
At the same time, Florenciella is more advanced in comparison with Epigonus having such characters as pres-
ence of enlarged, directed to sides and/or forward symphyseal teeth in jaws, of finely and densely denticulatd
edges of infraorbitalia 2–8 and of the orbiral edge of frontale, and fontanelle in bulla otica and having specific
traits of denticulation of opercular bones, having no separated distal element in the free pterygiophore between
the first and second dorsal fins, having modified scales, etc. The related genera Florenciella and Rosenblattia
may be synonyms.
