Type locality: Zambia, Solwezi

Despite the extensive sampling in north-western Zambia by ANHRT, this species has not been found and is seemingly rare. It is believed to be known only from the male holotype and a pair of paratypes in NHMUK. This taxon is quite unlike any other Hypotrabala with straight bilineate antemedial and postmedial fasciae, and lack of a forewing discal spot. The holotype is missing its abdomen and may have been dissected at some stage but lacks a corresponding slide or vial number ( Fig. 58 ). The paratype male has had the right-hand set of wings removed and de-scaled, and it has been dissected as stated in the original description ( Fig. 59 ); the corresponding slide ( Fig. 90 ) conserves a genital capsule of the Hypotrabala ground-plan, and the eighth sternite which is not unlike that figured by Tams (1953: Fig. 13 ). It is assumed that this slide is correctly labelled (see above) with a caveat that dissections of other specimens are needed for confirmation.
