Diagnosis

Males of C. digweedi resemble those of C. bertmaini, with the sternal concavity occupying about half of the sternal length, and the epigastric scutum strongly protruding. Males of C. digweedi can be easily separated by their ovoid cymbium-bulb complex with a broadly based embolus and a twisted bifurcate tip. Females can be easily distinguished from all other Cavisternum species by the broad semicircular epigynal rim as wide as the apodemes, and the extremely narrow copulatory duct.
