Etymology: Assessor: Latin, assessor, -oris = the person that tkes part in some play.
Eponymy: Meaning ‘assistant’ or ‘helper’, the allusion is not explained, but might perhaps refer to Francis (Frank) A McNeill (1896–1969), Whitley’s colleague at the Australian Museum, who, as carcinologist, probably helped Whitley with his ichthylogical [...] (Ref. 128868), visit book page.

Estimates based on models
Preferred temperature (Ref.
123201): 26.5 - 28.1, mean 27.3 °C (based on 60 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00175 - 0.01251), b=3.18 (2.95 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
