The Nepoidea are recognized on the basis of three synapomorphies (1-3), (28-1), and (38-1) and represent the most basal group consisting of two families: the Belostomatidae and the Nepidae. The Belostomatidae show three synapomorphies: (4-1), (32-1), (33-1), and the Nepidae: (0-1), (24-1), and (36-2).
La Familia Nepidae esta representada en el continente americano por los generos Telmatotrephes Stal, Ranatra Fabricius, Curicta Stal y Nepa Linnaeus (Stys & Jansson 1988).
Ranatra schuhi is also notable among Nepidae in general for its striking color pattern on the hemelytra, consisting of a red ground color overlain with yellow maculations and flecking, and with the veins creamy white with black dashes.
Waterscorpions are heteropteran bugs of the family Nepidae. All nepids have a slender non-retractable respiratory tube arising from the posterior end of the abdomen.
In the part of discussion, the ground plan of the morphological labial sensilla structures and the preliminary estimation of the characters of the labial sensilla in respect to phylogenetic value are compared with the basal model within the group (i.e., the basal taxa of the Nepidae and Belostomatidae) to the more diverse forms of these structures in more evolutionarily advanced groups (i.e., Corixidae, Ochteridae, Gelastocoridae, Aphelocheiridae, Naucoridae, Pleidae, Helotrephidae, and Notonectidae, resp.).

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.
ulcerans by aquatic biting insects, we conducted a field examination of biting water bugs (Hemiptera: Naucoridae, Belostomatidae, Nepidae) in 15 disease-endemic and 12 non-disease-endemic areas of Ghana, Africa.
