Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 11; Mjukstrålar i analfenan: 15; Ryggkotor: 32. This member of the Polyipnus spinosus species group has the following unique characters: with a single OVB photophore (vs. three in other members); VAV, ACA and ACB photophores form a nearly continuous series in the form of a shallow, sigmoidal curve along the ventral margin of the body from the pelvic-fin base to near the insertion of the posteriormost anal-fin ray (vs. a noticeable space between the VAV and ACA photophores in other members except P. fraseri with no ACA photophores, but there is a gap between the VAV and ACB photophores); and the ACA photophores are separate from each other, not united in a common organ; a combination of the following features further serve to distinguish the new species - relatively large eye with diameter 22.4 % SL; with spines on photophore scales of PV, VAV, ACB, and ACC clusters; with bifurcated posttemporal spines with prominent serration; ACB photophores 6; gill rakers 25 on left side, and 26 on right; a long and broad lateral pigment bar extending below the lateral midline (Ref. 115573).
Body shape (shape guide): short and / or deep; Cross section: compressed.
