Diagnosis. Sciadonus pedicellaris differs from the other four Sciadonus species by the following combination of characters: No distinct black spots dorsally and along midbody; pelvic fin length 1.0–2.2 % SL; dorsal fin rays 90–107; precaudal vertebrae 43–49; origin of anal fin below dorsal fin rays 44–56.
Size. Largest known specimen (126 mm SL) is a ripe female.
Distribution (Fig. 1). Earlier known from 19 specimens caught in the Northeast Atlantic, Northeast Pacific, the Solomon Sea and off New Zealand at 1169–5440 m (Nielsen 2018) and now additionally five specimens from the GAB and off southern Qld caught at 1816–4280 m.
Remarks. The present five specimens are compared to 19 specimens from most oceans (Nielsen 2018) and Table 1 shows agreement in all the 21 characters mentioned.
