  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...

Four new species and two new genera of theraphosid spider from Bolivia (Araneae: Theraphosidae)

Abstract

Two new genera, Bermejoa gen. nov. and Isiboroa gen. nov. are described to house the species Bermejoa zoeae sp. nov. and Isiboroa hamelae sp. nov., respectively. Two new species of existing genera are also described: Plesiopelma manni sp. nov. and Reversopelma herzogi sp. nov. Homoeomma peruvianum (Chamberlin, 1916) and Acanthoscurria sacsayhuaman Ferretti, Ochoa & Chaparro, 2016 from Peru are transferred to Isiboroa gen. nov., based on palpal bulb morphology and the absence of a stridulation organ. Consequently, the new combinations Isiboroa peruviana comb. nov. and Isiboroa sacsayhuaman comb. nov. are proposed.
