General morphology similar to  P. maximum maximum, except for having much stronger legs and chelicerae and pedipalps with more armaments ( Suzuki 1976). Scutal surface densely but regularly granulated. Ocularium short, generally canaliculate but dorsally armed with a row of small, regularly spaced denticules. Supracheliceral lamina pointed, sparsely scattered with small but distinct sharp granules. Pedipalpal tarsal claws with general reduced teeth that is more significant compared to other subspecies of  P. maximum, in some individuals the “teeth” are reduced to small, blunt granulations ( Suzuki 1973). Legs unarmed except for scatterings of small sharp denticles. Penis glans long, similar to that of  P. maximum formosum, with folded lateral alate wingings ( Suzuki 1973, Martens 1987).   Distribution.The Ryukyu Islands (Is. Kikai-jima, Is. Amami-oshima, Is. Okinawa, Is. Iriomote) ( Fig. 12).  Notes.This subspecies is univoltine and overwinters as juvenile. Adults appear from June to August. 5218235390 [496,739,1486,1510] Is.
