Etymology: Chlopsis: Greek, chloea = green + Greek, opsis = appearance (Ref. 45335); sagmacollaris: Name from Latin 'sagma' meaning saddle, and 'collaris' or necked, referring to the
distinctive dark pigment patch of the nape of the neck.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 397 - 405 m (Ref. 106145). Tropical

Eastern Indian Ocean: off northern Western Australia but probably more widespread in the eastern Indian Ocean and Timor Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 22.8 cm TL male/unsexed; (Ref. 106145)
Morphology | Morphometrics
soft rays: 357;
Vertebrae: 142. Distinguished by the high vertebral count (total 142, predorsal 12, preanal 42, precaudal 58), combined with the distinctive saddle-shaped pigmentation on the nape of the neck; overall coloration is much lighter than its congeners with the dorsal pigmentation being light brown to tan rather than the dark brown to grayish brown and ventral tip of its tail is relatively unpigmented rather than dark brown to black (Ref. 106145).
