Parthenogenesis and reproduction in Charinus ioanniticus (Kritscher, 1959) (Chelicerata, Amblypygi, Charinidae)

摘要

Charinus ioanniticus from the Greek island of Rhodes can reproduce parthenogenetically. Young animals hatched in captivity started their first reproduction at an age of about 1.5 years when they had reached body sizes of about a half to two-thirds ofthe size of fully grown specimens. Egg numbers of these small specimens ranged from one to six (up to 13 in fully grown specimens). All reproduction occurred between late winter and early summer. The observations are discussed with respect to the concept of insular parthenogenesis of Cuellar (1977).
