Soil Preference and Burrow Characteristics of Two Theraphosidae Species in Penang Island, Malaysia

  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 new species of Acanthoscurria Ausserer, 1871: proposal of the theraphosoides species-group and first published record of the genus from Colombia (Araneae: Theraphosidae)

Abstract
A remarkable new species of Acanthoscurria Ausserer, 1871, is described from Colombia, Acanthoscurria armasi sp. nov., representing the first published record of the genus from this country. New insights into palpal bulb morphology and biogeography of the newly-proposed theraphosoides species-group are provided.
