Etymology: Ostichthys: Greek,osteon = bone + Greek, ichthys = fish (Ref. 45335); alamai: Named after Mr. Ulysses Alama, Museum of Natural Sciences, College of Fisheries and Ocean Sciences, University of the Philippines Visayas, for his great contributions to the authors’ and other collaborators’ surveys at Iloilo during 2013-2017, when the new species was collected.
Eponymy: Ulysses B Alama is on the staff of the Museum of Natural Sciences, College of Fisheries and Ocean Sciences, University of the Philippines, Visayas. [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 13. This species is distinguished by the following characters: D XII,13; pectoral-fin rays 17-18 (modally 17); pored lateral-line scales 28-29 (28); scale rows between lateral line and middle of
spinous dorsal-fin base 3.5; lower gill rakers, with all rudiments 13 or 14 (13); middle dorsal-fin spines are relatively long, 7th dorsal-fin spine 14.5-18.3 (mean 16.3) % of SL; last 3 dorsal-fin spines are relatively long [10th dorsal-fin spine 7.7-9.8 (8.8) % of SL, 11th (penultimate) dorsal-fin spine 5.8-8.3 (6.8), 12th (posteriormost) dorsal-fin spine 7.0-9.8 (8.3) % of SL]; second to fourth anal-fin spines relatively long [second anal-fin spine 5.5-8.6 (7.1) % of SL, third anal-fin spine 15.2-18.3 (16.8) % of SL, fourth anal-fin spine 12.6-14.6 (13.5) % of SL]; caudal peduncle relatively long, its length 10.3-12.2 (11.2) % of SL; posteriormost dorsal-fin spine fused to the first dorsal-fin soft ray, the space between spine and ray about half that between bases of former and penultimate dorsal-fin spines; first body scale row usually below first dorsal-fin spine base (60 %) or between bases of first and second dorsal-fin spines (40 %); ventral part of maxilla not expanded ventrally even in large specimens; body scales with closely set, many developed spinules, fewer young spinules; narrow longitudinal white bands or rows of spots laterally on body when fresh (including large specimens), (usually lost after being preserved); dark red blotch on upper origin of pectoral-fin base (Ref. 119380).
