Vertebrae 10 + 16 = 26; dorsal-fin pterygiophore interdigitation pattern 3 / 32010 / 9. Body slender and elongated, depths at pelvic-fin and anal-fin origins 6.2–7.3 and 6.2–6.7 in SL, respectively. Body slightly compressed, oval in cross section, width 8.8–11.7 in SL. Head small, oval in shape, length 4.5–5.0 in SL; eyes large, length 2.7–2.9 in HL; space between eyes broad and slightly convex, interorbital width 3.4–3.7 in HL; snout blunt and not protruding before premaxilla, its length 4.6–5.0 in HL. Mouth small and oblique, upper-jaw length 2.5–2.7 in HL; its posterior end reaching slightly beyond vertical through anterior margin of eye. Upper jaw protrusible. Lower jaw projecting before upper jaw; its tip without any barbels, instead forming small blunt knob at symphysis. Two nostrils, with anterior one in short tube and situated at tip of snout and posterior one forming pore and situated behind vertical through anterior margin of eye. Canine teeth on premaxilla and dentary. Premaxillary teeth forming about 2 or 3 rows, with outermost teeth distinctly enlarged. Dentary teeth forming about 3 rows anteriorly and decrease to 1 row posteriorly; outermost teeth at lower-jaw tip and ca. 3–6 teeth on inner row distinctly enlarged. Vomer and palatine edentate. Gill rakers on outer surface of first arch longer than rest; rakers present on both outer and inner faces of all four arches. Gill slit present behind fourth arch. Gill filaments present on all four arches and subequal in length. Pseudobranchial filaments present but short. Gill membrane connected to isthmus; anterior end of gill opening not extending to posterior margin of preopercle. Body scales small, cycloid, and embedded into skin. Scales covering body, abdomen, chest, and pectoral-fin base; anterior-most scales on dorsum extending anteriorly to about upper end of gill opening, posterior-most scales extending onto caudal-fin rays posteriorly. Head, nape, isthmus, and gular areas naked. Head pores absent; sensory papillae present but mostly abraded due to bottom trawling. Origin of dorsal fin slightly behind upper pectoral-fin origin; dorsal-fin spines flexible and filamentous, fourth spine longest; adpressed spine reaching about middle to posterior one-third of second dorsal-fin base; length of longest spine in 1.2–1.5 in HL. Base of dorsal fins 1.4–1.5 in SL. Second dorsal-fin base long; all soft rays branched; its height 1.5–2.2 in HL. Posterior margin of pectoral fin rounded, length 1.5–1.7 in HL, its tip anterior to vertical through anal-fin origin. Pelvic fin long, length 0.6–1.2 in HL; its tip reaching anterior to anus when adpressed (one specimen reaching anal-fin origin); pelvic fin separated, not united anteriorly. Origin of anal fin below fifth dorsal-fin soft ray; anal-fin base 2.6–2.9 in SL; its height 1.9–2.1 in HL. Caudal fin rounded, length 1.0– 1.2 in HL. Caudal-peduncle short, length and depth 3.2–4.0 and 2.0– 2.1 in HL, respectively. Genital papilla large, covering anterior half of anus.</p><p>Coloration (fresh). Body pale to slightly pinkish or bluish (Fig. 1). Head paler than body and slightly yellowish; one yellow stripe from upper margin of eye, extending to about upper end of gill opening; three silvery-blue stripes on head, with upper most stripe just behind eye and extending onto opercle, second stripe below first one and extending from preopercle to opercle, last stripe originating from cheek below eye and extending onto opercle; upper opercle with one black blotch slightly smaller than pupil; lower opercle slightly silvery; snout slightly dusky, with nostrils yellow. First dorsal fin somewhat yellowish and with yellow stripes near base (some turned white); second dorsal fin dusky, with three yellow stripes. Anal fin dusky, with two or three yellow stripes; distal margin white. Pectoral-fin base with two horizontal silvery-blue stripes. Inner caudal fin yellow and encircled by three layers of U-shaped rings; innermost ring white and somewhat bluish, followed by yellow and white rings. Pectoral fin pale and scattered with black pigments on lateral and outer margins of fin rays. Pelvic fin uniformly pale.</p><p>Coloration (preserved). Body and head pale, with black pigments remaining (Fig. 2). Head with three stripes: upper-most stripe originates from behind eye and connected to blotch on upper opercle; second stripe originates from cheek, extending slightly upward to opercle and ending at pectoral-fin base; lower-most stripe originates from opercle and extending onto pectoral-fin base. First dorsal fin dusky, with one pale stripe proximally; second dorsal fin dusky, with two pale stripes proximally. Anal fin pale, with three dusky stripes. Caudal fin pale, with two dusky U-shaped rings; outer-most ring encircling distal margin of caudal fin. Pectoral fin pale and scattered with black pigments on lateral and outer margins of fin rays. Pelvic fin uniformly pale. Inner face of operculum, gill arches and filaments, oral cavity, including underside of tongue pale.</p><p>Distribution.</p><p>It was originally described from Luzon, the Philippines (Randall and Suzuki 2008), later reported from Milne Bay, Papua New Guinea (Allen and Erdmann 2024), and now recorded in southwestern Taiwan (this study). Our specimens represent the northernmost record of this species in the northwestern Pacific Ocean.</p><p>Remarks.</p><p>All specimens were collected in their respective years following typhoon events, and no additional specimens have been obtained since. This may suggest that the species inhabit areas not regularly sampled by trawling operations, such as nearshore zones or rocky substrates. The specimens were collected along with other gobies such as Mahidolia mystacina (Valenciennes, 1837); Oxyurichthys spp.; Paratrypauchen microcephalus (Bleeker, 1860); Tomiyamichthys russus (Cantor, 1849); and Tomiyamichthys smithi (Chen et Fang, 2003) (YS, YCF and YCH, pers. obser.).</p></div>	https://treatment.plazi.org/id/BEB603A630FF5A38873309C5D2466C38	Public Domain	No known copyright restrictions apply.
