Phytotelmata, or plant-held water bodies, often house complex aquatic invertebrate communities. Microdrile oligochaetes (Clitellata, Annelida) are known to be part of that community, but specimens are rarely identified to species level. Here we report three species of Enchytraeidae and three species of Naididae from a collection sampled in phytotelms of bromeliads in Cusuco National Park, Hondu...

Hsi-Te Shih, Hsueh-Wen Chang and Jiun-Hong Chen (1999) A review of the earthworms (Annelida: Oligochaeta) from Taiwan. Zoological Studies 38(4): 435-442. The study of earthworms of Taiwan began with the Japanese scholars Goto and Hatai (1898). The collecting sites from available publications are limited to Ilan, Taipei, Taoyuan, Hsinchu, Miaoli, Kaohsiung, and Pingtung. A total of 26 species be...

This study investigated the effect of main physicochemical factors in structuring aquatic macroinvertebrate assemblages three streams northern Tunisia. Aquatic and water surveys were carried out seasonally 2013, at pristine sites altered located, respectively, upstream downstream parts investigated. Macroinvertebrates sampled using a kick net Surber net, eight measured same time. Both biotic ab...

The semi-aquatic freshwater earthworm genus Glyphidrilus Horst, 1889 from Thailand was investigated based on extensive recent collecting. The species in this genus were characterized by their external and internal morphological characters of the location of wings, genital openings, genital organ structures and their locations, as well as the dimensions of body length and number of segments. Sev...

The Patagonian coast is characterized by the existence of pristine ecosystems which may be particularly sensitive to oil contamination. In this study, a simulated oil spill at acute and chronic input levels was carried out to assess the effects of contamination on the macrobenthic community structure and the bioturbation activity of sediments sampled in Caleta Valdés creek. Superficial sediment...

Two new earthworm species are described, Periscolex malibu sp. nov. (Rhinodrilidae) and Righiodrilus lebrijae sp. nov. (Glossoscolecidae). They were found in relicts of tropical dry forests surrounding wetlands in the southern department of Cesar, located near the Caribbean coast of Colombia. Periscolex malibu sp. nov. is close to P. fuhrmanni Michaelsen, 1913 by the position of both clitellum ...
