Dr. Helen K. Larson has recently reviewed the gobiid fish genera Eugnathogobius and Pseudogobiopsis (Gobioidei: Gobiidae: Gobionellinae) from Indo-West Pacific and Southeast Asian localities with descriptions of three new species. Some materials were redescribed. Key to Gobionelline genera is given and keys to both genera were also provided. Three species of Eugnathogobius were found in Malaysia - E. siamensis, E. polylepis and E. kabilia but only E. siamensis is confirmed found in freshwater ecosystem of Peninsular Malaysia. Two other species - E. variegatus and E. illotus were absent in Malaysia but the former reported from Thailand, Singapore, Indonesia and Papua New Guinia and the later was reported from Thailand, Singapore, Brunei and the Philippines. Interesting! There are four valid species of Pseudogobiopsis and at least two species were reported from Malaysia - P. oligactis and P. paludosus. Both species present in Peninsular Malaysia.
This publication is timely and able to ease difficulties in identification of both genera. The full paper can be read at: http://rmbr.nus.edu.sg/rbz/biblio/57/57rbz127-181.pdf
