Abstract

Prior to this study the genus Tigidia Simon, 1892 of the Brush-footed Spider family Barychelidae was represented by eight species endemic to Madagascar and Mauritius Islands. The first occurrence of Tigidia in India is reported here with the description of three new species from the Western Ghats, T. sahyadri sp. nov. from Uttara Kannada District, Karnataka; T. nilgiriensis sp. nov. from Kotagiri, Nilgiri District, Tamil Nadu and T. rutilofronis sp. nov. from Maruthamalai, Coimbatore District, Tamil Nadu. This genus is probably a Gondwana relict. Natural history information is provided for all the species.

M. Siliwal

Manju Siliwal has been working on spiders since 1997. She has specialized on taxonomy of primitive spiders (mygalomorphs including tarantulas) and has described many new species from India. Her main interest lies in taxonomy, ecology and conservation of Indian spiders. Her contribution to this paper is in identifying the species and preparing the manuscript including taxonomy of first species and refining descriptions of other two species.

N. Gupta

Neha Gupta is MSc in biodiversity and conservation and is very much interested in ecology and conservation of Indian spiders. For her M.Sc. dissertation, she worked on the ecology of trapdoor spiders of the family Idiopidae in Uttara Kannada, Karnataka. She found the first specimen of Tigidia from the Western Ghats. She also assisted in finalizing illustrations and text.

R.V. Sanap

Rajesh Sanap is a graduate student interested in the study of mygalomorphs spiders and scorpions. He has described new species of scorpions and trapdoor spiders. His contribution in this paper is in finding the two species of Tigidia from the Western Ghats. He also contributed to this paper in morphometry, preparing illustrations of the latter two species.

Z.A. Mirza

Zeeshan Mirza is a student of Bhavan’s College, Mumbai currently persuing his Bachelors degree in Zoology.
