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 [...] Francis Alexander ‘Frank’ McNeill (1896–1969) was an Australian ichthyologist and carcinologist at the Australian Museum in Sydney.

Maturity: Lm ? range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 2334)
Adults are found in lagoon and seaward reefs, aggregate in caves, often upside down. Males incubate the eggs mass in their mouth (Ref. 9710). Minimum depth reported from Ref. 27115. Breeding in the aquarium is possible (Ref. 130646).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Eggs are guarded by the male parent (Ref. 205), in his mouth for 15-16 days (Ref. 130467)..
