Western Pacific: Japan, New Guinea and Palau.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 2.0 cm SL male/unsexed; (Ref. 55345); 2.0 cm SL (female)
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. Diagnosis: Predorsal scales and a bony interorbital about pupil diameter in width. Second dorsal spine elongated. Fifth pelvic fin ray branched dichotomously once and 55-80% of the fourth. Scales on cheek absent; one or two cycloid scales on the upper opercle; usually two rows of scales anterior to the pelvic fin base. Snout and lower half of the caudal peduncle with a slight sprinkling of melanophores. A broad, rounded, median ridge present on the snout and anterior interorbital region. Unique to the genus, a large, bilateral, open nasal pit, instead of the usual nasal sac with anterior and posterior openings (Ref. 55345); characterized further by semi-translucent pinkish, abdomen and most of head reddish pink, merging with tapered pink stripe to middle caudal fin base; midline of snout with blue-white spot; internal white stripe above vertebral column; longitudinal scale series 23-25; predorsal scales 6-8 (Ref. 90102).
Collected from a quiet, sheltered bay (Ref. 55345). Inhabits sheltered bays in 9-26 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 29.3, mean 28.7 °C (based on 1128 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
