The study describes the identification of the spider assemblages with respect to their diversity within the Peechi-Vazhani wildlife sanctuary. A total of 106 species, from 24 families were recorded from the area,which forms baseline information of spiders of the sanctuary. Families showed varying degrees of  habitat fidelity with some being abundant while others rare. Amongst these, Salticidae, Araneidae, Oxyopidae and Lycosidae were to have mor especies in the area. However, analyses of functional groups, e.g., ground runners (29%) showed the positive influence of structural complexity of the habitat.The presence of different species in all habitats highlights the importance of conserving a wide array of representative habitats within ecosystems.

Only three species of Annandaliella are known from the Western Ghats of Kerala, A. travnacorica Hirst 1909, A. ernakulamensis Jose and Sebastian 2018, A. pectinifera Gravely 1935. A. travnacoricais distinguished by its primary apophysis on first leg, which has a horn-like projection with a pointed black spine at the tibial end. The presence of a tibial apophysis with a thick black spine distinguishes it from A. ernakulamensis  and  A. pectinifera. A. travancorica has previously been reported in Kerala’s Travancore, Kozikode, and Thrissur. This is the first report from Peechi Wildlife Sanctuary.

Neoheterophrictus chimminiensis Sunil Jose, 2020 was previously only found in the Chimmini forest area, but it has recently been found in the Nelliyampathy forest region of Western Ghats, indicating its distribution. Taxonomic description illustrations and measurements of chimminiensis are added.
