DISTINGUISHING FEATURES .— 1D II,8; P 14–17; V 7; total GR-I (inner) 9–13; scale rows below origin 2D 5–9, usually 6–7, below midbase 1D 5–7; lateral line scales over distance equal to pre-1D length 26–34; scale rows between base of V and gill cover 10–14; pyl. caeca 9–13, short, thick. Grooved lateral line present; body scales relatively small, finely covered with erect spinules. Jaw teeth all small. Snout length 23–27% HL; interorbital width 31–34%; orbit diameter 29–30%; suborbital width 11–12%; postorbital length 38–42%; orbit-preopercle 29–33%; upper jaw 30–33%; barbel 6+–11%; 1D-2D interspace 20–22%. (Adapted from Iwamoto 1997.) DISTRIBUTION .— Known from Japan to Taiwan and the Philippines . In Taiwan , specimens were taken from the South China Sea in 634–954 m . REMARKS .— More specimens of this species must be examined from near the type locality off Japan to properly circumscribe the species and determine its difference from other described species .
