Etymology: Grallenia: Named for Gerald R. Allen, (G+R+Allen+suffix '-ia'), in honor of his great contribution to our knowledge of the diversity of coral-reef fishes.; larsonae: Named for Helen K. Larson, for her extensive contribution to goby taxonomy and systematics, and who collected and carefully preserved most of the type specimens..

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 7; Spine anali: 1; Raggi anali molli: 7; Vertebre: 27. This species is distinguished by the following set of characters: D VI+I,6–7; A I,6–8; first dorsal-fin spine not produced into filament; pelvic frenum present; cephalic sensory canals and associated pores present; 22–30 longitudinal scales. Coloration in alcohol is tan with 8 widely spaced, small, brown spots in mid-lateral row on side of the body; faint dark bar of stellate melanophores across anterior cheek; scattered pepper-like melanophores on anterior part of upper opercle It is closely related to Grallenia arenicola from Kashiwa-jima island of southern Japan. This species has relatively fewer scales anterior to the level of the second dorsal fin origin compared with Grallenia arenicola (Ref. 123066).
Specimens were collected using rotenone on sand and rubble bottoms, in habitats ranging from sand flats, isolated coral knolls, reef slopes, and reef edge/fringing reef with scattered corals (Ref. 123066).
