Caudal tibiae with three dorsal apical or subapical teeth on each margin. Tarsal claws have one apical and subapical tooth. Wings have a discal cell, or are without a discal cell; without a subapical cell. The apical segment of the maxillary palpi is short and never longer than subapical one. The apical and subapical teeth are sharp and short, but the proximal tooth is blunt. May be terminal (apical), subapical, lateral, gynobasic, or subgynobasic. There are four dull ferruginous subapical costal dashes. For respiration, the shells of fissurellids have a single apical or subapical perforation ("keyhole"). A subapical bristle is absent on tibia. A reported subapical retroflex articulation in Grootfontein ! Chrysidids have simple mandibles, with usually one or two subapical teeth. The apex is slightly tinged with grey and with some subapical dark streaks. In the subapical region, actin filaments are arranged into a collar-like structure. The subapical half of the termen has a half moon-shaped brown to grey-grown spot. In the subapical pattern the style arises to the side slightly below the apex.
