MEASUREMENTS AND RATIOS. LTg/BTg (n = 2) = 2.22; BV/LV (n = 1) = 3.42; LF/BF (n = 1) = 1.21.

Male genitalia

Pygofer with digitiform process dorsally on each side of anal tube, directed dorso-posteriorly ( Figs 15–16 ); posterior margin of pygofer strongly sinuate on ventral 1/ 3 in lateral view ( Fig. 15 ). Anal tube elongate, about 1.34 times longer than broad near apex, with lateral margins diverging from base to apex in dorsal view ( Fig. 16 ); ventral margin sinuate and apical margin rounded in lateral view ( Fig. 15 ). Gonostyli elongate, twice as long as broad, with apex broadly rounded and dorsal and ventral margins subparallel in lateral view ( Fig. 15 ); strong hook-shaped tooth under dorsal margin close to pygofer, curved ventro-posteriorly and prolonged by a small rounded lobe on gonostylus wall dorsoposteriorly ( Fig. 15 ). Phallic complex with latero-ventral curved sclerotized process on each side ( Fig. 17 ), processes with ante-apical expansion directed anteriorly ( Fig. 18 ).

Distribution

Borneo. The species seems widespread on the island (see map Fig. 7 ).
