Figure 2 View FIGURE .
MATERIAL EXAMINED.— SWT: ASIZP 65627 (1, 70 HL, 385+ TL); CD 229, 880– 1062 m.
DISTINGUISHING FEATURES.— A species of Gadomus with chin barbel about 29–72% of HL; length elongated P ray 2–3 times HL; prolonged ray in 1D and V greater than 1.5 times HL; 1D II,9–10; P i17–i18; V 8; outer gill rakers bluntly tipped, lathlike, short, about half orbit diameter, (5–6)+(21–23); pyl. caeca 24–29; interorbital width 16–17% HL; orbit diameter 21–24%; suborbital depth 10–15%; upper jaw length 55–60%; chin barbel 29–72% (compiled from Gilbert and Hubbs 1920 and ASIZP 65627).
DISTRIBUTION.— Taiwan ( SWT) to n. Mindanao, Philippines, in 929–1280 m.
REMARKS.— Our identification of the single Taiwan specimen is tentative. Its barbel length is somewhat shorter (29% HL cf. 61–72%) and suborbital somewhat deeper (15% HL cf. 10%) than in the type specimens of G. magnifilis . The Taiwan specimen appears similar to G. introniger in its gill-raker count, barbel length, orbit diameter, and bluntly tipped gill rakers, but differs in having a slightly narrower interorbital (17% cf. 20–23%), slightly deeper suborbital (15% cf. 10–13%), and longer orbit-to-preopercle distance (51% cf. 44–49%). The pyloric caeca could not be count- ed in our specimen because they had been previously extracted and were unavailable; they may have offered additional clues to the correct identity. Gilbert and Hubbs (1920:396) considered G. denticulatus as closely related to G. magnifilis , but compared to our specimen, G. denticulatus has a much narrower interorbital space (1.5–1.8 into orbit diameter cf. 1.3), slightly larger orbit (23–24% HL cf. 21% in our spec.), and slightly fewer gill rakers (4–6)+(17–22) (23–27 total), cf. 6+23 (29 total).
