Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); dalerocheila: From the Greek daleros for hot or fiery, and cheilos for lip, in allusion to the fiery red snout and lips of this species (Ref. 46430).
Eponymy: Holly Arnold. This is hardly an obvious eponym, as daleros means hot or fiery, and cheilos means lip, referring to the goby’s red snout and lips. However, the name also alludes to Ms. Arnold, who helped collect the holotype, and who, according to [...] (Ref. 128868), visit book page.

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 2.0 cm SL male/unsexed; (Ref. 46430)
Dorsal spines (total): 7; Dorsal soft rays (total): 9 - 11; Anal spines: 1; Anal soft rays: 7 - 11; Vertebrae: 26. Brick-red in color, usually with two paler bars (one across pectoral base, the other centered on the space between the two dorsal fins); snout and chin fiery red, broken by two pale horizontal stripes from the dorsal and ventral margins of the pupil, respectively. The dorsal stripe passes anteriorly across the nostrils, the ventral stripe crosses the upper jaw and may continue onto the chin (Ref. 46430).
Collected from lagoons as well as from oceanic drop-offs (Ref. 46430). Forms schools and feeds on plankton (Ref. 46430).

Estimates based on models
Preferred temperature (Ref.
123201): 18.9 - 28.2, mean 26.8 °C (based on 12 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
