Summary:
A small snubnose goby with brown scale margins forming a net-like pattern on the head and body, 5–6 distinct dark brown or black elongate blotches along the mid-side, the posteriormost extending onto the caudal fin and coalescing with a broad vertical dark brown bar on the caudal-fin base.

More Info
Distribution |
Gulf of Carpentaria, Northern Territory, and Torres Strait, Cape York, Queensland. Elsewhere the species occurs in New Guinea region (Sahul Shelf) east of Lydekker’s Line: Indonesia (Aru Islands and southern New Guinea), northern and southern Papua New Guinea. Inhabits shallow estuarine to lower freshwater areas, including mangrove creeks and streams under tidal influence. |
Features |
A moderate-sized Pseudogobius species with second dorsal rays I,6–7; anal rays I,6–7; pectoral rays 14–17; 16 segmented caudal rays in 9/7 pattern; lateral scales 23–27; TRB 7–8; predorsal scales 6–7; opercle with several rows of cycloid scales, cheek naked; shoulder girdle with smooth to fleshy edge; tongue reduced, tip blunt; in males, outer row teeth evenly spaced, compressed, with bluntly pointed tips while in females, outer row teeth compressed, blunt-tipped and closely-set. |
Colour |
Scale margins on head and body edged with brown, giving body net-like pattern, 5–6 distinct dark brown or black elongate blotches along mid-side of body, posteriormost at hypural crease where it extends onto caudal fin and coalesces with broad vertical dark brown bar on caudal-fin base. |
Similar Species |
This species may be confused with Pseudogobius aquilonius. P. hoesei differs in having a translucent caudal fin with 5–6 rows of small dark spots (versus caudal fin translucent, plain, with one brown bar at base in P. aquilonius); about 5–6 elongate blackish blotches along mid-side of body (versus about 5–6 X-shaped or elongate small brown blotches along mid-side of body); and first dorsal fin with two indistinct diffuse grey to blackish bands along fin (versus first dorsal fin translucent with broad diffuse brown band across most of fin). |
Etymology |
The species is 'Named for our goby-friend and colleague Doug Hoese, in recognition of his years of collection and photography of many poorly known gobies (and because he took a wonderful photo of the holotype)'. |
