Comments

Taxonomy from Gregorová 1997.

General description from Gregorová 1997, p. 125: "The size of our specimens varies from 79 to 100.3 mm in standard length, but from individual bones, especially from the head, we can assume a larger size.  Danilchenko (1960) gives the size as 50 to 180 mm. They are slender fish with maximum body height at the pectoral fins. The head is relatively long and voluminous, and the snout is prominent.  The orbit is small and protruding, its diameter is slightly larger than the distance in front of the orbit. The odd fins are high, set back in the second half of the body without the caudal fin and opposite each other or the anal fin is slightly behind the dorsal fin.  The pectoral fins are arranged low, almost at the level of the ventral margin. These rays reach almost at their end the insertion of the pelvic fins. The latter are closer to the anal fin than to the pectoral fin."
