The earthworms collected from the West Khasi Hills District of Meghalaya are dealt with in this paper. Besides the taxonomic identification of the earthworms in to 32 species fewer than 12 genera, 4 families and 2 orders, the species have also been assigned in to separate ecological groups. 6 species are epigeic or epi-anecic, 11 species are endogeic, 2 species are endoanecic, 5 species are endo-polyhumic and 1 species is endo-mesohumic. The list also includes 6 endemic species. Amynthas populosus is recorded for the first time from India, while 8 species are reported for the first time from Meghalaya. Out of the 32 species from the District, 31 species are recorded for the first time from West Khasi Hills district.

Abstract


The earthworms collected from the West Khasi Hills District of Meghalaya are dealt with in this paper. Besides the taxonomic identification of the earthworms in to 32 species fewer than 12 genera, 4 families and 2 orders, the species have also been assigned in to separate ecological groups. 6 species are epigeic or epi-anecic, 11 species are endogeic, 2 species are endoanecic, 5 species are endo-polyhumic and 1 species is endo-mesohumic. The list also includes 6 endemic species. Amynthas populosus is recorded for the first time from India, while 8 species are reported for the first time from Meghalaya. Out of the 32 species from the District, 31 species are recorded for the first time from West Khasi Hills district.
