Differs, among other characters, from P. monteithi by a dorsoventrally curved axis pala-parameroids, hooked edges of penis, and small parameres each with a comma-like apical hook ( Fig. 78 ). In a specimen with erect genitalia ( Figs 79, 80 ) the parameroids extend far posteriorly, the trigonium with the unarmed endophallus forms an erect cone. The parameres are directed obliquely outward and upward, while the styli point down, with their fine fringes on the caudal face.
