Two new species of Charinus Simon, 1892 from Brazil with biological notes (Arachnida; Amblypygi; Charinidae)

Charinus acaraje n. sp. is described from Gruta Pedra do Sino, Santa Luzia, Bahia, Brazil and Charinus asturius n. sp. from Morro Pacuiba, Ilhabela, Sao Paulo, Brazil. Charinus asturius is recorded from the most southern locality in South America. Charinus asturius is a nocturnal forager that in captivity accepted live termites and Drosophila (adults and larvae). The most common defensive behaviours of C. asturius were: to flee when disturbed by light or touch, and to autotomize parts or entire legs when manipulated. Most of the reproductive activity of the species probably occurs during the wet-warm season (from October to March). The clutch size ranged from 10 to 15 eggs and the pre-nymphs hatched and remained on the mother's back for 2 weeks. The limited occurrence of C. asturius on Ilhabela Island (from 100 to 400 m on only one mountain) and its demands for specific microhabitats make the species threatened and vulnerable to the environmental damage caused by human occupation in the lower lands of the study site.36110711
