Etymology: Pseudogobius: Greek, pseudes = false + Latin, gobius = gudgeon (Ref. 45335); hoesei: Named for Douglas Hoese, for his years of collection and photography of many poorly known gobies; also for the wonderful photo of the holotype that he took..

Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 6 - 7; Anale stekels: 1; Anale zachte stralen: 6 - 7. This moderate-sized species is distinguished by the following characters: D2 I,6-7; A I,6-7; pectoral rays 14-17; segmented caudal rays 16 in 9/7 pattern; lateral scales 23-27; transverse scale count 7-8; predorsal scales 6-7; opercle has several rows of cycloid scales, cheek no scales; shoulder girdle, smooth to fleshy edge; tongue is reduced, its tip blunt; males with outer row teeth evenly spaced, compressed, with bluntly pointed tips; females with outer row teeth compressed, blunt-tipped and closely-set. Colouration: scale margins on head and body edged with brown, giving the body a net-like pattern, distinct dark brown or black elongate blotches 5-6 along mid-side of body, posteriormost at hypural crease where it extends onto the caudal fin and coalesces with broad vertical dark brown bar on fin base (Ref. 126575).
Occurs in shallow-water estuarine to lower freshwater, from mangrove creeks and streams under tidal influence. Associated with several local endemic Pseudogobius species, although it can extend further into lower freshwater streams than other species (allopatric with P. jeffi) (Ref. 126575).
