Etymology: Marcelogobius: Named after Marcelo Kovačić, who is the leading active goby expert for the Eastern Atlantic, Mediterranean and Ponto-Caspian region; janetarum: Named for Mrs. Janet Camp and Ms. Janet Eyre, who generously supported our goby research; noun in feminine genitive (plural).
Eponymy: Janet Van Sickle Eyre (d: 1955), along with Janet Camp (both of Reef Environmental Education Foundation), gave generous support to the authors’ goby research. (See Eyre) (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9; Vertebrae: 27. This species is distinguished from its congeners by the following set of characters: vertebrae 27; D2 I,10; scaled posterior quarter of the predorsal region in front of D1 origin and with several rows of cycloid scales; scales on body, cycloid anteriorly and ctenoid posteriorly; scales in lateral series 30-32, with anterior oculoscapular canal; absence of preopercular head canal; suborbital row 7 each a single papilla, suborbital rows 2 and 4 are close to orbit; branchiostegal membranes are uniformly black below preopercle, forming V-mark (Ref. 118256).
Collected exclusively from small caves and rock crevices with a specimen observed lurking out of a small cave before it was collected, whereas the other four known specimens were retrieved after spraying clove oil (a fish anesthetic) into rock crevices on vertical walls covered with the coral Tubastrea caboverdiana (Ref. 118256).
