Liparidae (Snailfishes)
Etymology: Psednos: Greek, psednos, -e, -on = rare (Ref. 45335); micruroides: From Barnard's original specific name micrurus, and used because of the similarity between the two species (Ref. 42989).

Maturité: Lm ?  range ? - ? cm
Max length : 3.1 cm SL mâle / non sexé; (Ref. 42989)
Rayons mous dorsaux (Total) : 38; Rayons mous anaux: 30; Vertèbres: 43. Coronal pore present, 6th infraorbital pore absent, 3-4 pores in temporal canal; eye 22.7% HL, mouth terminal, and gill slit equal to eye diameter (Ref. 42989).
