Three new species and new records of Oligochaeta, Glossoscolecidae, from the Venezuelan Andes

Abstract

Five species of Oligochaeta, Glossoscolecidae, from Venezuela, Merida State (1,500 to 4,350 m a.s.l.) were studied by dissection and serial microscopical sections. Andiorrhinus (Amazonidrilus) gavi n. sp. is characterized by the space aa wider in XX-XXIII and seven pairs of hearts in VII-XIII. A. (Meridrilus) rimeda, n. sp. is notable for the pair of puberal bands lateral do b in XX-XXIII flanked by two longitudinal cords. Rhinodrilus mucuba, n. sp. has a typical arrangement of the setae and spermathecae. New observations are reported for the previously known Onychochaeta windlei and A. (M.) kuika; the variability of the latter species is recorded.
