Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); bisella: Name from Latin 'bi' meaning two, and 'sella' meaing a seat or saddle, referring to the two white saddle-like markings on the dorsal and ventral margins of the caudal peduncle; noun in apposition.. This species has been informally referred to as "Trimma RW sp. 53 (in lit.).".. More on author: Winterbottom.

This species is distinguished by the following characters: colour pattern distinguishes this species where freshly collected specimens have a brown-grey body; a bright red peduncle margined dorsally and ventrally by two large white saddles; vertical orange bars 4 on a salmon background on the head; midline of nape naked; interorbital trench well developed, second dorsal spine elongated, fifth pelvic fin ray unbranched; when preserved, the two light saddles on the caudal peduncle and the light vertical bars on the head visible; without scales in the predorsal midline or on cheek (Ref. 118045).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00427 - 0.01860), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
