  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...

New data on spiders (Arachnida: Araneae) from the Carrascal de la Font Roja Natural Park (Alicante, Spain)

Abstract

The results of an annual sampling in the Natural Park of Carrascal de la Font Roja (Alcoi, Alicante) are presented. Lathys sexpustulata Simon, 1878, Canariphantes aff. naili (Bosmans & Bouragba, 1992) and Bassaniodes graecus (C. L. Koch, 1837) are the first appointments for the Iberian Peninsula. Tapinopa disjugata Simon, 1884 is the first records for Spain. In addition, the family Miturgidae, 4 genera and 26 species, are the first records for the Valencian Community. The family Theraphosidae, 5 genera and 9 species, are also the first records in Alicante province. As a result, the Natural Park of Carrascal de la Font Roja has increased its araneofauna with the first record of 8 families, 54 genera and 88 species. The number of Ibero-Balearic endemic species amounts to 22. Add the presence of a male of Gluvia dorsalis (Latreille, 1817), family Daesidae, order Solifugae.
