Etymology: Didogobius: From Dido, queen of Carthage who killed herself when abandoned by Aeneas; Greek, mithology; lanceolatus: Name from Latin 'lanceola', a diminutive term of lancea, meaning 'lancet', i.e. a small lancet. referring
to the lancet-shaped caudal fin of the new species, a character shared in the iChromogobius-Didogobius species complex only shared with the type species of the genusD. bentuvii.
Eponymy: Dido was a princess of Tyre (in modern-day Lebanon), who sailed the eastern Mediterranean (where D. bentuvii occurs) to found the city of Carthage and become its first queen. She is particularly noted for her role in Virgil’s Aeneid. (Ref. 128868), visit book page.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 7; Raios dorsais moles (total) : 13; Espinhos anais: 1; Raios anais moles: 11; Vértebras: 27. This species is distinguished from all currently described members of the genera Didogobius, Chromogobius, Marcelogobius and Peter, by the following set of characters: caudal fin lanceolate; eyes small or reduced (vs. large eyes); vertebrae 27; D2 I,13, A I,11; predorsal region is in front of D1 naked; body squamation reduced, with only a few cycloid scales anteriorly and in tail region; with anterior oculoscapular canal with only pores ?,??,??,??; posterior oculascapular and preopercular head canal are absent; suborbital row 7 with more than five papillae; suborbital rows 2 and 4 close to orbit (Ref. 130223).
Like other members of the subfamily Gobiinae, this species has a cryptobenthic lifestyle, living at least temporarily sheltered in soft sediment burrows. Its discovery was accidental after being collected with (silty) mud The sediment sample contained agglutinated worm tubes and shells of Atrina chautardi. Live associated fauna comprised a second unidentified fish species and beyond abundant polychaetes, gastropods, bivalves, amphipods and shrimps. A potential burrow-dwelling lifestyle might provide shelter against predators on this relatively flat seafloor lacking any hard substrates (Ref. 130223).
