| Summary: | Owstonia nudibucca new species (Figures 61‒63) Owstonia totomiensis. Gloerfelt-Tarp and Kailola, 1984:229, unnumbered color photo (misidentification; brief description; ANSP catalog number of photographed fish [holotype] listed on p. 347). Holotype.

Paratypes. 2 specimens, 93‒288 mm SL. SAIAB 201332 (1, 288) and SAIAB 201333 (1, 93), Andaman Sea, off Gulf of Mottama (Martaban), 14°31'12"N, 93°44'24"E, 268.5 m, R/V " Dr. Fridtjof Nansen " sta. 58, Peter N. Psomadakis, 9 May 2012. Diagnosis. A species of Owstonia with naked nape and cheeks; LL pattern type 3, including a short vertical side branch slightly anterior to dorsal-fin origin (Fig. 6 D); oblique body scale rows in mid-lateral series 38‒42; caudal peduncle depth 2.3‒1.7 times in its length. Description. (Where counts vary, those of the paratypes are given in parentheses.) A species of Owstonia with LL type 3, in which lateral line does not contact posttemporal sensory canal near anterodorsal margin of gill opening, continues posteriorly just below dorsal-fin base and anteriorly where it makes a complete loop across nape and also has the horizontal section of lateral line with a short ventral side branch slightly anterior to dorsal-fin origin; lateral line ends below dorsal-fin soft rays 16-17. Dorsal fin III, 21; anal fin II, 14; pectoral fin 22 (21‒22); gill rakers 18 + 29/31 = 47 or 49 (16‒18 + 27‒32 = 45‒50. Vertebrae: precaudal 11, caudal 17, total 28; anal-fin pterygiophores anterior to 1st haemal spine 2. Oblique body scale rows in mid-lateral series about 38/44 (ca. 50); nape and cheeks naked. Papillae in slight depression behind tip of premaxillary ascending processes 4, arranged in 2 almost equally spaced pairs. Lower limb margin of preopercle with about 7 or 8 (6‒7) spines. Teeth in outer row of each premaxilla 17/18 (18‒23), anterior 8−11 teeth moderately elongate with blunt tips; ... |
