Short description. The body is generally elongated with a long antennule that generally reaches the tip of the urosome. Male: the antennule is geniculated; the antepenultimate segment of the right antennule bears an antepenultimate process which contains 5–8 teeth on the outer margin. The right exopodite 2 of P5 is larger and longer than the left, and has a long, broad, and slightly curved terminal claw on the postero-median area; and with a short lateral spine protruding from the exopodite 2. Female: the antennule is straight. The pair of P5 leg is symmetrical. All the morphological characters concur with the species descriptions of Lai and Fernando (1980).

Ecological distribution. Filipinodiaptomus insulanus was found in lakes, reservoirs, and golf course lagoons. This is a Philippine-endemic calanoid copepod ( Lai and Fernando 1980, Mamaril 1986).
