Filistata hasselti Simon, 1906: 308 . Female holotype from Indonesia, locality uncertain (“ Java, Sum., ver. Celebes ”), deposited in MNHN AR 5438, examined by photos.

Pritha hasselti – Lehtinen 1967: 260.

Notes

Lehtinen (1967) claims to have examined a type specimen of F. hasselti deposited in the Zoölogische Museum der Universiteit van Amsterdam, Netherlands. This is unusual since type specimens of Simon are usually deposited in the MNHN. The specimen we examined is correctly labelled and fits with the description given by Simon (1906) and we have no reason to believe it is not the holotype. We examined photos of this specimen as its distribution suggested it might belong to Labahitha , but it clearly belongs in the Filistatinae , not in the Prithinae , due to the tarsal macrosetae, calamistrum in a crest and with a median gap, and the deep thoracic fovea ( Fig. 31 ). We did not perform a dissection to examine and illustrate its genitalia. The subfamily Filistatinae is otherwise not represented in the Oriental region, and thus the generic affinity of Filistata hasselti is unclear. The only other filistatine specimen known to us from the Oriental region is a juvenile from Malaysia, Selangor, Kepong, Aug. 1947, R. Traub leg. deposited in the AMNH, whose generic affinity is also unclear. We allocate F. hasselti in Filistata to restore the original combination, and because it shares a calamistral gap with Filistata and Zaitunia Lehtinen, 1967 .
