The cave-dwelling dipluran (Diplura, Campodeidae) on the edge of the Last Glacial Maximum in Vancouver Island caves, North America (Canada)
A new cave-dwelling dipluran of the North American endemic genus Haplocampa is described, coming from a couple of caves excavated in a small limestone karstic area near Port Alberni, Vancouver Island (British Columbia, Canada). To Haplocampa belong five soil-dwelling species. L. M. Ferguson cited no...
