Summary:
A moderate-sized Pseudogobius with brown scale margins, 3–5 small brown elongate blotches or spots along the mid-side, with the last blotch on the midbase of the caudal fin extending onto the caudal fin and coalescing with a blackish blotch on the fin, and sometimes forming a narrow vertical dark bar on the fin base. The caudal fin is translucent dusky grey with scattered brownish spots near the base.

More Info
Distribution |
Endemic to the north-east coast of Queensland, from the Daintree region to Round Hill south-east of Gladstone, including near-shore islands. Inhabits shallow estuarine areas, including mangrove creeks and muddy tide-pools, at depths of 0–1 m. Also in marginal habitats such as by boat ramps and overgrown drains. |
Features |
A moderately sized Pseudogobius with second dorsal rays I,6–7, usually I,7; anal rays I,6–8, usually I,7; pectoral rays 15–17; 16 segmented caudal rays, usually in 9/7 pattern; lateral scales 23–26; TRB 7–9, usually 8; predorsal scales 6–7; opercle with three rows of large cycloid scales; nearly always with single cycloid scale on cheek right behind eye; shoulder girdle with thin bony flange; tongue short; in males, teeth in outer row of upper jaw slightly flattened, tips blunt or rounded, with two small curved symphyseal canines behind anterior tooth rows; females with outer row teeth of upper jaw small, compressed, evenly sized and blunt-tipped. |
Colour |
Scale margins edged with brown, 3–5 small brown elongate small blotches or spots along mid-side of body with posteriormost blotch at midbase of caudal fin, extending onto fin and coalescing blackish blotch on fin and may form narrow vertical dark bar on fin base; caudal fin translucent dusky grey with scattered brownish spots near base. |
Etymology |
This species is named for Helen K. Larson's 'husband Jeff [Larson], who has inadvertently learned much about gobioid fishes over 50-something years, so it is high time that he had a Queensland goby named for him.' |
