Hello Steven,

There are three known Macrothele species from Taiwan, M. holsti, M. simplicata and M. taiwanensis and then three more species from the Ryukyu Is., M. yaginumai and M. amamiensis (Yayema) and M. gigas (Amami-oshima).

The only known species from the area where this female was collected is M. holsti. Both M. simplicata and M. taiwanensis are known from the northern parts of Taiwan.

Due to the shape of the spermathecae, both me and Bastian thought it was M. holsti. Also Joachim Haupt agreed with us.

The spermathecae does not look anything as the spermathecae of M. taiwanensis. Unfortunately I do not have any publications on M. simplicata myself, but I will get Saito, 1959 the next week. If any one have Saito, 1933b, I would appreciate a P.M..
