Etymology: Microgobius: Greek, mikros = small + Latin, gobius = gudgeon (Ref. 45335); urraca: Named after the Smithsonian Tropical Research Institute’s research vessel the Urraca, which served the institute between 1994-2007; noun in apposition.
Eponymy: Not an eponym but named for the Smithsonian Tropical Research Institute’s research vessel ‘Urraca’, which contributed a wealth of information on fish diversity in the tropical Americas (1994–2007) and from which the type was collected (2003). (Ref. 128868), visit book page.

Duri punggung (Keseluruhan (total)) : 8; duri punggung lunak (Keseluruhan (total)) : 14; Duri dubur: 1; Sirip dubur lunak: 14; vertebrata, bertulang belakang: 27. This species is distinguished from Microgobius urraca in having the following characters: lateral scale rows 67-76; patch of ctenoid scales under the pectoral fin absent; unpigmented epaxial myosepta; first dorsal fin with a distinct oval-shaped dark blotch; three blue-white stripes on a dark caudal fin. It differs from the remaining eastern Pacific congeners in the number and type of scales (pectoral- and pelvic fin base without scales; pre-anal region with small embedded cycloid scales; small scales on anterior and ventral portions of trunk, partially imbedded, and in irregular rows, becoming larger and arranged in distinct rows dorsally and posteriorly; no small patch of ctenoid scales beneath pectoral fin); D1 VII, D2 I,14; A I,14; fleshy dorsal crest poorly developed and overall color pattern (Ref. 91780).
Body shape (shape guide): elongated; Cross section: oval.
Found over sand or sand and leaf litter bottoms; where collections are found in the latter, this species was collected with several specimens of Ptereleotris carinata and M. erectus. Presumed to be a burrowing species (Ref. 91780).
