Etymology: Platygillellus: Greek, platys = flat + Theodore Nicolas Gill (1837-1914) researcher of abyssal fishes and systematics (Ref. 45335).

Western Atlantic: southern Florida, USA and Bahamas to Panama.

Morphology | Morphometrics
(total): 16 - 17;
soft rays: 25 - 26. Pale tan or white with 4 broad reddish-brown bands on side between nape and caudal fin base. Dorsal and caudal fin rays have dark spots. 3 spines in dorsal finlet (Ref. 26938).
Inhabits sand and rubble areas around coral reefs or exposed rocks. Absent from surf beaches (Ref. 27742). The reddish-brown bands along the sides of the fish serve as camouflage when the fish partially buries itself in sand (Ref. 26938).
