DISTRIBUTION. Belize, Panama, Venezuela ( YOUNG, 1990; MILLER, 2016). A common species in Belize, known from the Belize, Cayo, Stann Creek and Toledo districts ( Fig. 2 H ).

HABITAT. This is the most common species of Bidessini in Belize and is found in various types of lentic water ( Figs 3–6 ) and in pools in intermittent and temporary streams. It is often found together with B. mobilis .

NOTE. MILLER (2016) incorrectly includes Honduras in the distribution of this species instead of Belize (formerly known as British Honduras), which is however the type locality of this species.
