Korte beschrijving Morfologie | Morfometrie

Dorsale zachte stralen (totaal): 7-9; Anale zachte stralen: 8 - 12; Wervels: 31 - 33. Diagnosed from Phalloceros anisophallos, Phalloceros megapolos, Phalloceros spiloura, Phalloceros reisi, Phalloceros buckupi, Phalloceros alessandrae, Phalloceros lucenorum, Phalloceros uai, Phalloceros pellos, and Phalloceros malabarbai by the female urogenital papilla straight along midline and located between the anus and the base of first anal-fin ray (vs. curved to the right, located laterally; border of the anal aperture in contact with the first anal-fin ray). Differs from Phalloceros tupinamba, Phalloceros leptokeras, and Phalloceros aspilos by the female urogenital papilla straight along midline (vs. slightly left turned); absence of a lateral ramus of the female urogenital papilla (vs. lateral ramus present); and small and simple hook in gonopodial appendix (vs. large sickle like hook). Can be distinguished from Phalloceros caudimaculatus, Phalloceros heptaktinos, Phalloceros ocellatus, Phalloceros mikrommatos, and Phalloceros leticiae by having a hook in the gonopodial appendix (vs. hook absent); from Phalloceros titthos by the absence of symphyseal papillae on large females (vs. symphyseal papillae present); and from Phalloceros enneaktinos by the possession of seven or eight dorsal-fin rays (vs. nine) (see remarks); from Phalloceros elachistos by the hook of gonopodial appendix not forming a lateral protuberance (vs. very small in adults, forming a lateral minute protuberance). In juveniles hook present and located on the appendix corner (vs. absent or (rarely) minuscule, when present in juveniles hook never situated on the appendix corner). Skin present covering the tip of appendix on juveniles (vs. skin absent). Distal half of appendix narrower than proximal half (vs. approximately as wide as or slightly narrower than proximal half) (Ref. 76852).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00683 - 0.01843), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
