Etymology: Lubricogobius: Latin, lubricus = slipperiness, smoothness + Latin, gobius = gudgeon (Ref. 45335); dinah: Named in honor of Dinah Halstead who was the first to discover the species (Ref. 45340).
Eponymy: Dinah Halstead was the first person from Papua New Guinea to became a diving instructor. [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Anal spines: 1; Anal soft rays: 7. Anterior nostrils absent; no scales detected; pelvic disc with a frenum; body depth 3.35-3.6 cm SL; head length 2.75-2.8 in SL; head compressed, its width 1.2-1.3 in its depth; caudal fin rounded, shorter than head, 2.9-3.4 in SL; orange in color, the upper part of the head and body abruptly white; fins orange-yellow (Ref. 45340).
Inhabits sand and rubble bottoms, taking refuge in dead shells, empty bottles and tunicates (Ref. 90102). Hovers a short distance above the substrate (Ref. 45340). Feeds on zooplankton (Ref. 45340).

Estimates based on models
Preferred temperature (Ref.
123201): 23.5 - 28.9, mean 27.9 °C (based on 132 cells).
Phylogenetic diversity index (Ref.
