Borbora View in CoL species-group

This is a new species-group, established to accommodate Crotonia sterigma sp. nov. and C. borbora Luxton, 1987 , previously considered to be a member of the Capistrata species-group (cf. Colloff, 2009b for definitions of species-groups). The Borbora species-group differs from the Capistrata group (see below) in having greatly elongated setae c 1 and c 2 which originate on compound apophyses with bifurcating apices emerging from a single base. The caudal apophyseal cluster is on a stalk, the notogastral plate is narrow with parallel sides and the outline of the opisthosoma, delineated by the lateral margins of the notogastral shield, is lozenge-shaped. The anteriolateral part of the notogastral shield is waisted, and the prodorsum may be expanded posteriolaterally.
