Moreover, the same researcher regarded the completely reduced intercalary sclerites as a synapomorphy for the
Notonectidae, Pleidae, and Helotrephidae.
Brief history of Cuban aquatic and semiaquatic Heteroptera: In the 19th century, the classic work of Guerin-Meneville (1857) listed 14 species (not including synonyms and misidentified species) of aquatic and semiaquatic Heteroptera from Cuba, belonging to the families Saldidae, Gerridae, Hydrometridae, Veliidae, Belostomatidae, Corixidae, Naucoridae, Nepidae, and
Notonectidae.
His scheme is similar to that of Rieger (1976) in the placement of Nepoidea [i.e., (Nepidae + Belostomatidae), see Schuh and Slater 1995:110] as sister group to the remaining Nepomorpha, and in having as the most derived clade the Notonectoidea [i.e., (
Notonectidae + (Helotrephidae + Pleidae))].

Invertebrates consisted of a variety of groups including micro-crustaceans (copepods, ostracods, and Daphnia), red swamp crayfish (Procambarus clarki), Corbiculidae (Corbicula fluminea), tapeworms, dipteran larvae and adults,
Notonectidae, and odonate nymphs and adults.
(2002a, 2002b) senalaron la presencia de correlaciones positivas y altamente significativas entre la abundancia de las familias Corixidae y
Notonectidae con la profundidad del criadero y la temperatura del agua; asimismo informan de correlaciones positivas y significativas de las familias Libellulidae, Coenagrionidae y Mesoveliidae con la profundidad del criadero y tambien de la familia Veliidae con la profundidad del criadero, el oxigeno disuelto, la conductividad y la temperatura del agua; sin embargo, estos autores no informan sobre la existencia de otro tipo de correlacion entre las multiples variables del habitat que fueron estudiadas y la abundancia de las especies de Anopheles (Grillet et al.
Los generos Buenoa (
Notonectidae) y Rhagovelia (Veliidae) fueron los mejor representados (11,3%) con seis especies cada uno.
Macroinvertebrates were collected from eight taxonomic groups: one suborder, Zygoptera, and seven families, including the coleopterans Gyrinidae and Hydrophilidae, odonates Aeshnidae and Libellulidae, and hemipterans Belostomatidae, Corixidae, and
Notonectidae. Not all macroinvertebrates were in each pond, and the median value was 6 taxa/pond (range 4-8, SD 1.3).
