RESUMO
A new genus of Gerridae (Insecta, Hemiptera, Heteroptera) in the subfamily Trepobatinae, Telmatometropsis gen. nov., with a single included species, T. fredyi sp. nov., is described from the Colombian Pacific region. Representatives of the new genus were collected in mangrove lagoons of Buenaventura Bay, Valle del Cauca Department. The new genus can be diagnosed by the relative proportions of the antennomeres, the shape of the male fore tarsus, and by the black markings on the head, thorax and abdomen.
RESUMO
Neoplea hyaloderma n. sp. and N. melanosoma n. sp. (Insecta: Hemiptera: Pleidae) are described from Colombia. This increases the number of species of pleids known from Colombia to four, all of which are in the genus Neoplea Esaki China. A key to the species of Neoplea of Colombia is included. Neoplea melanosoma appears to be part of a species complex with N. maculosa (Berg) and N. tenuistyla Roback Nieser, and herein is called the N. maculosa species complex. We also note that there is probably at least one additional species in this complex from Suriname that was previously identified as N. maculosa. Neoplea melanosoma n. sp. appears to most closely resemble N. maculosa from Argentina, Bolivia and Paraguay than the geographically closer N. tenuistyla. Neoplea hyaloderma n. sp. appears most closely related to N. lingula Roback Nieser, which is also in Colombia.
