Prionocyphon storeyi Watts, 2010b  

( Figs 61−64 View FIGURES 61 − 64 , Table 2)

Material studied. 1♂: Mossman Gorge , N. Qld. 24 Apr 1967 D.H. Colless   ; 1♂: Mt. Spec   . NQ. 1/GB / J. G. Brooks bequest 1976 (both ANIC). 1♂: Mt. Tambourine [sic!] Q. A.M.Lea   ; 1♂: Blue Mts. , Blackburn [ NSW] (both SAMA).  

Differs from its relatives by the slenderness of the genitalia. Parameroids strongly sclerotized and longer than club-shaped hyaline parameres (arrow in Fig. 61 View FIGURES 61 − 64 ). Slender styles with terminal fringe long and distinct. Trigonium apex hook-like, in slide mounts its anteriorly diverging contour lines are seen to connect to sides of the penis. The appearance changes with position, and the shape possibly differs slightly between specimens ( Figs 61–63 View FIGURES 61 − 64 ). The apex was mistaken for a cover of the endophallus at rest ( Watts 2010b).

Endophallus long and slender, front end divided and armed with small spinules, further back with long spines ( Fig. 64 View FIGURES 61 − 64 ). Caudally a single dense pack of long spines present, separated by pale ring from dense pelt of long spines which spread outward upon eversion ( Fig. 61 View FIGURES 61 − 64 ). At rest, membranous outer surface of retracted endophallus at penis tip with scaly surface (arrow in Fig. 63 View FIGURES 61 − 64 ).

The new records from southern Queensland and New South Wales close the gap between the known occurrence in North Queensland and the record from Lord Howe Island ( Watts 2010b).
