Liosomadoras Fowler, 1940

Liosomadoras Fowler, 1940: 226 [type-species: Liosomadoras morrowi Fowler , by original designation and monotypy]. Gender masculine.

Diagnosis. Liosomadoras is distinguished from all other genera of Auchenipteridae , except Spinipterus Akama & Ferraris, 2011 and Trachycorystes Bleeker, 1858 by having spines on the posterior cleithral process (vs. absent). Spinipterus is distinguished from Liosomadoras by having pectoral- and dorsal-fin spines with four rows of serrations running from base to the tip of the spines; lateral margins of skull roofing bones ornamented with a single row of spines, and groove along dorsal midline posterior to dorsal fin, in which the adducted dorsal fin rests. Trachycorystes is distinguished from Liosomadoras by having nasal dorsally expanded and visually exposed, eight branched pelvic-fin rays, and dorsal-fin spine with smooth posterior face. See discussion for additional notes on the diagnosis of the genus.

Etymology. From the greek leios meaning smooth, plus soma meaning body, in reference to the smooth body (i.e., without ossified scutes as doradids usually have), and the suffix - doras, as traditionally applied to genera of the Doradidae (Fowler described Liosomadoras as belonging to the latter family, and not to Auchenipteridae ). Gender masculine.
