Earthworm species in native and planted forests in Brazil.

Over 150 species of earthworms are known from the Brazilian Atlantic rainforest, but many more are expected to live in this megadiverse biome. In the present study, we evaluated earthworm species occurrence and diversity in native and reforested areas in four National Forests in three Brazilian states: Três Barras National Forest (Santa Catarina), Irati and Piraí do Sul National Forests (Paraná) and Capão Bonito National Forest (São Paulo) using formalin and hand sorting methods. A total of 13 species were found, five exotic and eight natives (of which four were new, undescribed species), belonging to six genera and five families (Rhinodrilidae, Glossoscolecidae, Ocnerodrilidae, Benhamiidae, Megascolecidae).

Two new earthworm species (Oligochaeta: Annelida) of the Orinoquia region of Colombia.

Two new earthworm species from grassland and herbaceous plant formations in the departments of Arauca y Casanare (Orinoquian region of Colombia) are described, Righiodrilus cusiani sp. nov. (Glossoscolecidae) and Andiodrilus cravijae sp.

New species of Cognetti, 1908 (Oligochaeta: Rhinodrilidae) from Venezuela and Brazil.

Findings pertinent to 11 earthworm species from Venezuela and Brazil are reported. Six of these species are described as new to science, one is re-described and relocated in the genus Andiorrhinus, and new sites of occurrence are reported for four other species. Eight species of oligochaetes were found in the Andes in the state of Mérida, Venezuela: Andiorrhinus (Turedrilus) duranti sp.
