Diagnosis. A species of Owstonia with a LL pattern type 2 that typically forms a loop across nape; oblique body scale rows in mid-lateral series 27‒30; in fresh specimens dorsal, anal and caudal-fins with a wide, white, distal margin and submarginal red stripe.

Description. A species of Owstonia with LL pattern type 2, consisting of a lateral line that originates from posttemporal sensory canal near anterodorsal margin of gill opening, extends upward and forms a "T" connection with horizontal section of lateral line ( Fig. 5 View FIGURE 5 B) that extends posteriorly just below dorsal-fin base to soft rays 16−17, with the anterior section extending beyond dorsal-fin origin and forming a loop across nape ( Fig. 6 View FIGURE 6 E). Dorsal fin III, 22–24 (typically 22); anal fin II, 14; pectoral fin 17–20; gill rakers 12–15 + 24–27 = 36–41. Vertebrae: precaudal 11–12, caudal 17‒18, total 28–29 (exceptionally 28); anal-fin pterygiophores anterior to 1st haemal spine 3 ( Fig. 7 View FIGURE 7 B). Oblique body scale rows about 27–30; nape scaly and cheek scale rows 2–3. Lower limb margin of preopercle with skin-covered spines so reduced as to be easily over-looked ( Fig. 8 View FIGURE 8 G). Papillae in slight depression behind tip of premaxillary ascending processes 4, each pair of papillae about equally spaced ( Fig. 14 View FIGURE 14 E). Teeth in outer row of each premaxilla 18–28, with some of anterior ones spike-like; no inner teeth. Teeth in lateral row of each dentary 10–12; symphyseal teeth 3–5, moderately short and spike-like, and with 0−1 inner teeth anteriorly. Pelvic fin probably sexually dimorphic, depressed fin ranging from extending only to anus to reaching anal-fin origin. Caudal fin lanceolate. In 10 specimens, 52‒84 mm SL, caudal fin 1.5‒2.0 times in SL; head 3.5‒4.3 times in SL; body depth at anal-fin origin 4.5‒6.4 times in SL.

Color pattern in alcohol: Dorsal fin uniformly pale; membrane connecting maxilla and premaxilla with a prominent black stripe variable in length, extending only about 2/3 distance or to end of premaxilla, and inner membrane covering posterior part of dentary also black. In the fresh holotype, head and body were rosy pink, becoming mostly white ventrally; dorsal and anal fins rosy with a relatively wide, white distal margin and submarginal red stripe; outer margin of caudal fin also has a wide white border followed by a slightly wider, dark red submarginal stripe, remainder of fin rose colored.

Proportions of 10 specimens 44‒84 mm SL mm SL, as percentages of SL: predorsal length 21.8‒27.4; preanal length 47.2‒56.2; dorsal-fin base 62.2‒68.2; anal-fin base 33.5‒39.6; pelvic-fin length 17.9‒28.0; caudal-fin length 47.7‒71.1; body depth at anal-fin origin 15.5‒21.0; head length 22.3‒30.2; upper jaw length 11.1‒17.2; upper jaw depth 5.2‒7.2; orbit diameter 10.6‒13.7. As percentages of head length: upper jaw length 49.5‒58.2; orbit diameter 42.3‒49.3.

Comparisons. Owstonia tosaensis , the only other species with LL pattern type 2, differs (characters of O. sarmiento in parentheses) in having more oblique body scale rows in mid-lateral series 44–54 (vs. 27–30) and cheek scale rows 4–5 (vs. 2–3), different number of anal fin rays I, 15–16 (vs. II, 14) and a very different color pattern. Owstonia sarmiento also is the only species in which the anal fin has 2 supernumerary spines.

Etymology. Named for Malcolm Sarmiento , then director of the Philippine Bureau of Fisheries and Aquatic Resources.

Distribution. ( Fig. 25 View FIGURE 25 ) Known from off Luzon Island, Philippines, Sulawesi, New Caledonia, and Queensland, Australia, where trawled in about 215– 415 m.
