Distance between anterior tip of isthmus and first pair of IP photophores about 3 times greater than combined length of anteriormost six IP photophores (66.7% of isthmus length). Secondary photophores very small, scattered over head and body, most densely clustered on cheeks, along dorsum, between OV and PV organs and between PV organs of neighbouring sides, absent on fin-rays. Postorbital organ large, elongate, tapered posteriad, 1.4 times eye diameter. Antero-ventral corner of jet-black tissue encircling the photogenic gland of postorbital organ extends anteriad to a vertical through the center of eye (
