  Soil Preference and Burrow Characteristics of Two Theraphosidae Species in Penang Island, Malaysia Abstract Tarantulas play a crucial role in maintaining ecological balance by regulating insect populations. However, little is known about the soil preferences and burrow structures of tarantulas in Malaysia. This study aims to determine the soil preference as well as the burrow structure of  Coremiocnemis cunciularia  and  Chilobrachys andersoni  from Penang Island. The soil characteristics of the soil samples collected around the burrows of  Coremiocnemis cunciularia  (n = 30) and  Chilobrachys andersoni  (n = 30) were determined using soil texture analysis. The measurements and burrow structures from adults and juveniles of  Coremiocnemis cunciularia  and  Chilobrachys andersoni  were determined. It was revealed that the moisture content and clay percentage in the soil samples around burrows of  Chilobrachys anderso...

A trial study on the spider diversity (Araneae species) in Agartala City of West Tripura district in Tripura, India

Abstract

This study reported the diversity of spiders in Agartala city of West Tripura district in Tripura, India. A total of 9 families, 14 genera and 16 species were recorded. The most abundant family was found Araneidae (25%), followed by Salticidae (18.5%), Sparassidae and Nephilidae (12.5%), and Sicariidae, Pholcidae, Therididae, Tetragnathidae, and Thomisidae presented similar percentage of abundance (6.25%) in this study. This study exclusively reports for the first time the presence of the Sicariidae family in Tripura, along with morphological characters and behaviours, like web-building structure and activity time, were also analyzed for the spiders collected in this study.
