Eugnathogobius siamensis (Fowler)

Distribution. Plover Cove Reservoir (GBIF.org, 2021); Tai Lam Chung Reservoir (H.T. Cheng, pers. comm., 2021).

Native range. (Southeast Asia) and South China.

Remarks. Restricted to reservoirs that receive raw water from mainland China but not known from the Dongjiang and adjacent river systems, although it may have been overlooked because of its tiny size (≤ 40 mm TL (Froese & Pauly, 2021)). This goby is neither in the aquarium trade nor used in aquaculture. It has been recorded from Lai Chi Wo estuary in the New Territories, Hong Kong ( Larson, 2009), but has not been reported from South China or Hong Kong since and does not appear to be represented by native populations in Hong Kong.
