  New insights into maternal care and juvenile dispersal in Pterinopelma roseum (Araneae: Theraphosidae) Abstract Tarantulas (Theraphosidae) exhibit a wide diversity of reproductive behaviors, yet many aspects of their natural history, particularly those related to maternal care and juvenile dispersal, remain poorly known. Pterinopelma roseum is a species distributed in southern Brazil and northeastern Argentina for which information on reproductive biology is limited. The aim of this study was to document maternal care, egg sac composition, and juvenile dispersal through the monitoring of a female collected together with its egg sac in Misiones Province, Argentina. The female was maintained under controlled laboratory conditions and observed daily until juvenile dispersal. During the incubation period, the female actively protected the egg sac, remaining in contact with it most of the time and displaying defensive behaviors when disturbed, while continuing to feed regularly. The e...

The first record of Orthochirus glabrifrons (Kraepelin, 1903) (Scorpiones: Buthidae) from the United Arab Emirates

Abstract


Orthochirus glabrifrons (Kraepelin, 1903) (Scorpiones: Buthidae) was described from Oman (Muscat). Here, we summarize known localities from Oman as well as records from the United Arab Emirates, which is the new country record for this species. Illustrations of morphology of both sexes are given together with a map of distribution. A lectotype of Orthochirus glabrifrons (Kraepelin, 1903) is designated. Paraorthochirus kaspareki Lourenço & Huber, 2000 and Paraorthochirus kinzelbachi Lourenço & Huber, 2000 are synonymized with Orthochirus glabrifrons (Kraepelin, 1903), syn. n.
