Derilissus lombardii Sparks & Gruber 2012

This species is distinguished from its congeners (and all other Bahamian gobiesocids) by the following characters: bright orangish-red coloration, yellow head, a prominent black oval patch on the caudal peduncle; pattern of papillae in disk region C; anteriorly, 2 distinct medial clusters, each comprising 8-9 closely arrayed papillae, and a single papilla anterior of each cluster, are present (vs. 2-5 papillae in each central cluster and 4-5 papillae arranged in a distinct crescent posterolaterally); posteriorly, papillae in disk region C are in a crescent pattern with a single additional papilla dorsal to its midpoint (vs. papillae in an inverted V-shaped pattern in D. nanus, D. altifrons, D. kremnobates; clumped in D. vittager); posterior margin of disk region B in the new species is strongly convex (vs. straight to weakly convex) with the rows of papillae arranged serially in a semi-circular pattern forming concentric crescents (vs. rows more or less straight); possess a total of 47 pectoral-fin rays (Ref. 91048).

Dorsal soft rays (total): 8; Analsoft rays: 7; Vertebrae: 25

Apparently closely associated with deep reefs, not straying far from the safety of a coral head (Ref. 91048).
