Abstract: The earthworm fauna of the wetlands of India is highly undocumented. We have carried out a survey of earthworms in the Kuttanad wetland, an integral part of the Vembanad-Kol Ramsar Site, India’s largest wetland of international importance. Current investigation has documented 17 species belonging to 7 families. Megascolex travancorensis pentagonalis Stephenson, 1916 and Glyphidrilus fluviatilis Rao, 1922 were reported for the first time since their original descriptions. Based on the current study, M. t. penta… Show more

This study presents a comprehensive catalogue of the moniligastrid earthworms (Moniligastrida, Moniligastridae) of the world. A total of 176 valid species/subspecies belonging to 5 genera are known to exist in this primitive family. Drawida is the speciose genus with 147 species/subspecies. Of the various moniligastrids, three species of Drawida are considered as peregrine outside its normal Asian range. Among the valid species, occurrence of 30.68% are known only from the type locality. It is noteworthy that the types of 125 (71.02%) species are currently known to exist in various repositories around the world. The existence of the remaining species can only be inferred from the literature since their types are either non-existent, missing, dried out, or lost. Present catalogue includes valid scientific names, synonyms, type locality, type respository details along with registration number, geographic distribution pattern within its native range, and references.

Three new earthworm species of the genus Drawida Michaelsen, 1900, namely D. jatinderi Narayanan, sp. nov., D. paliwali Narayanan, sp. nov. and D. proboscidea Narayanan, sp. nov., are described from materials collected from the Kerala state of south-western India. D. jatinderi Narayanan, sp. nov., belongs to D. travancorensis Michaelsen, 1910 species group, characterized by spermathecal pores at C setal line, male pores at mid bc setal lines, glandular prostate, spermathecal atrium present, dorsal pores, and genital markings absent. Whereas D. paliwali Narayanan, sp. nov., and D. proboscidea Narayanan, sp. nov. belong to the D. robusta robusta (Bourne, 1886) group, characterized by glandular prostates and bilobed spermathecal atria. D. jatinderi Narayanan, sp. nov., and D. proboscidea Narayanan, sp. nov. were collected from the midlands of Ernakulam district, and D. paliwali Narayanan, sp. nov., was collected from the higher altitude evergreen forest of the Parambikulam Tiger Reserve of Palakkad district. Here we provide a detailed description of the external and internal characteristics of the new species, along with illustrations of the key characters. With the new findings, a total of 52 Drawida species are known from the Western Ghats biodiversity hotspot.
