Dorsal soft rays (total): 16; Anal soft rays: 12. The genus is distinguished by the following characters: D1 5, D2 11, bases of two last rays substantially connected to each other), A 12, P 19, V i + 5, LL ca, 25, SqTr 5; premaxillaries are not protractile; with very wide coronal commissure; pore D unpaired, located in the middle of interorbital space; no preopercular pores; with a pore above preopercle (G); general
configuration of pores of seismosensory system of head: B', D(s), E, F, G, H'; the two first rays of first dorsal fin substantially elongated and filamentous; all rays of vertical fins unbranched; most internal rays of right and left pelvic fin connected to each other with membrane at one-fourth of their basal length; caudal fin lanceolate; approximately 8 anterior transversal scale rows on body are cycloid; subsequent 17 scale rows are ctenoid; ctenii arranged in row and are numerous; presence of a large longitudinally elongated pigmented spot under eye; other pigmented pattern on body and fins of preserved fish absent (Ref. 117107).
