New material studied. 1♂: Melville Island W.D. Dodd [NT] ( SAMA).

The new record is from close to the type locality, minor differences between the two known specimens are not thought to be taxonomically significant. In the present specimen the lateral points of T8 are sharply pointed and more similar to the paramedian ones. The tips of the tegmen are fully extended, and the short knee-shaped paramedian processes bear a completely transparent straight filamentous appendage with a small black tip ( Fig. 15). This appendage was overlooked in the type where the membranous region of attachment was not properly seen.
