Pseudocetonurus cf. septifer [sensu Sazonov and Shcherbachev, 1982]

Pseudocetonurus septifer : Chiou et al., 2004b:46, fig. 17 (1 spec., ASIZP 61237, 147 mm TL; Da-xi, Taiwan [ NET]).— Shao et al., 2008: table 2 (3 spec., Taiwan [ NET]).

MATERIAL EXAMINED (1 spec.).— NET: ASIZP 61237 (1, 147 TL), Da-xi .

DISTINGUISHING FEATURES.— 1D II,8–12, usually 9 or 10; P i16–i20; GR-I (outer/inner) 7–12/13–18, GR-II 14–18/14–17. Snout length 25–34% HL; preoral length 19–27%; postorbital 47–59%; orbit to preopercle 53–64%; suborbital 19–26%; outer gill slit 23–31; body depth 75–95; V-A 12–38%; height 1D 52–66%; length V 41–63%. Head about 5.0–5. 5 in TL; greatest width about 1.5 into greatest depth; interorbital about 2.3–3.0 into HL; suborbital deep, almost vertical and lacking modified scutelike scales; Mouth large, upper jaw extends to below midorbit. Barbel almost rudimentary, <0.5 orbit. Sensory canals of head greatly expanded, but sensory pores small; free neuromasts poorly developed. Grooved lateral line present.

DISTRIBUTIONs.— So far known only from the nw. Pacific off Taiwan.

REMARKS.— Based on the presence of a grooved lateral line, this specimen is probably an undescribed species. The only other member of the genus, P. septifer Sazonov and Shcherbachev, 1982 , known from the Saly-Gomez and Nazca ridges in the southeastern Pacific and off Hawaii, lacks a grooved lateral line.The Taiwan species was first recorded as P. septifer by Chiou et al. (2004b) and subsequently by Shao et al. (2008).
