Hydrometra guianana Hungerford & Evans

Distribuição no Brazil: PA, AM, MT.

Biological aspects: Collections resulted in 11 individuals of this species, found in 2nd to 3rd order streams, usually on pools. On the case of station PT 26, specimens were collected on remaining pools on the river bed, which was almost dry between September and November.

Comments: The geographical distribution of this species is similar to H. comata , extending from Trinidad & Tobago and northern South America to areas of Cerrado on eastern MT. Dias-Silva et al. (2010) mistakenly identified some specimens of this species as H. argentina .
