Northwest Pacific: only known from the South China Sea at about 380 to 400 km east of Hainan Island Occurrence in the Western Central Pacific uncertain, marginal in the South China Sea (Ref. 11146). For unavailability of material to be examined, the generic placement and recognition of this species is provisional.
西北太平洋: 已知只來自南中國海於大約 380 到 400 公里在中西太平洋的海南島發生以東不確定的, 邊緣的在南中國海.(參考文獻 11146) 因為材料的不有效被調查, 屬的定位與這種的辨認是暫時的。

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.5   ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
