  A further new species for the genus Ananteris Thorell, 1891 (Scorpiones: Ananteridae) from a poorly prospected region of Brazilian Amazonia Abstract  A new species of the genus Ananteris Thorell, 1891 is described from the region which today defines the ‘Reserva Biológica do Río Trombetas’ in the state of Pará, Brazil. The collection of the unique specimen, presently study, took place previously to the definition of this reserve, in a joint field trip with a team of the Instituto Brasileiro de Desenvolvimento Florestal (IBDF). Ananteris antoni sp. n. is described based on one female specimen collected in a zone of dense humid forest, under death log. With this new description, the number of Ananteris species known for the scorpion fauna of Brazil is now raised to 33. Lourenço W.

CHECKLIST OF ARACHNIDS IN THE HIGHLANDS AREA OF GUNUNG LEDANG NATIONAL PARK, JOHOR, MALAYSIA

Abstract


Mount Ledang National Park is one of the famous hiking spots in Johor, Malaysia which is the 1,276-meter peak of Mount Ledang. Between 21st-25th August 2023, a visual encounter survey method was conducted from 0900-1700 and 2000-2300 hours to document the Arachnid species that occur at 900-1200 meters above sea level. In total, 27 species from 14 families of arachnids were recorded from two orders; Araneae and Opiliones. Clustering analysis showed that Pendeta Trail and Batu Hampar Trail have 70% similar species composition, and Telekom Trail has a 37% difference between the two trails. Extrapolation of the species accumulation curve shows an increasing trend and has not reached an asymptote. The analyses on estimated species richness revealed that Arachnid species richness was at a minimum of 32 species, and a maximum of 47 species. Interestingly, a new record of tube trapdoor spider, Damarchus workmanii, and an undescribed Psednocnemis tarantula species found from this survey shows the importance of preserving the highland areas of this national park which remains to be further explored.
