Male. The 7th abdominal dorsal process bears three lobes that terminate at the same plane; lateral lobes are small and directly somewhat diagonally; the medial lobe is subtruncate and ca. 4X the width of the lateral lobes ( Fig. 43 View Figs ). The specilla are broadest basally, scarcely recurved and slightly tapered anteriorly, and bear raised tubercles distally along the inner and outer margins ( Figs. 44‒47 View Figs ). The subanal lobes are recurved anteriorly, tapered distally, and ca. 80% the length of the specilla ( Fig. 46 View Figs ).
