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.

Bandtail Snubnose Goby, Pseudogobius hoesei Larson & Hammer 2021

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)'.
Species Citation	Pseudogobius hoesei Larson & Hammer 2021, Zootaxa 4961(1): 34, Figs. 12-13. Type locality: Bellvue Creek, Embley River, Weipa, Queensland, Australia.
