Bacillometra ventralis Esaki, 1927

Geographical distribution: French Guiana and Brazil.

Distribution in Brazil: North Region (AM) ( Nieser 1970d).

Hydrometra Latreille, 1796 (7 species)

Comments: Hydrometra fuanicana Drake, 1954 was described from Peru, but in the checklist of American Hydrometridae provided by Drake and Lauck (1959), Brazil is the only country cited for this species. This is probably the result of a mistake, not a correction or new record. On the same list, a similar error occurs in the distribution of H. sztolcmani Jaczewski, 1928 , which is wrongly recorded from Guatemala instead of Brazil, as pointed by Bachmann (1977).
