Etymology: Bathygobius: Greek, bathys = deep + Latin, gobius = gudgeon (Ref. 45335); geminatus: Name is derived from the past participle of the Latin verb 'geminare', meaning paired, doubled, or repeated, referring to the diagnostic pattern of vertically paired spots that are repeated 6-7 times laterally along the body of this species.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following characters: 17-18 pectoral rays; 36-38 (modally 37) lateral scale rows; upper jaw length 10.3-10.7% SL; anterior extent of predorsal squamation reaching anteriorly to vertical through posterior margin of preopercle, with a few scales sometimes extending slightly beyond this point; with 2-3 dark blotches on each element of first dorsal fin giving appearance of 2-3 longitudinal stripes across fin; lower body with 2 rows of dark spots, spots in 2 rows directly above one another, beginning immediately behind pectoral fin base and terminating just anterior to dark blotch at base of caudal fin; upper and lower spots more distinctly separate from one another anteriorly, becoming closer to one another and loosely connected posteriorly; arrangement of spots appearing as 6 to 7 sets of vertically paired spots often forming '=' shaped markings along ventral portion of trunk (Ref. 85559).
Specimens collected in Florida were along the rocky and sandy shorelines with seagrass in a sheltered bay, taken along with B. soporator. A single specimen was collected in Puerto Rico on a sheltered rock and pebble shoreline near the mouth of an irrigation canal, along with B. soporator, B. lacertus and a single specimen of B. antilliensis. GenBank accession number for Col sequence of holotype: HM748368 (Ref. 85559).
