THE LARVAE OF SOUTHERN AFRICAN NOTONEMOURIDAE (PLECOPTERA)

Larvae of the southern African stonefly genera Aphanicerca Tillyard, D esmonemoura Tillyard, Aphanicercopsis Barnard, Afronemoura Illies, Aph anicercella Tillyard and Balinskycercella Stevens & Picker are describ ed for the first time. Setal and other characters facilitate simple an d accurate generic identification, and often specific identification. A key to the larvae of stonefly genera is provided. Diagnostic abdomin al setal patterns of most of the widespread species (13 of the 22 know n species) are illustrated. Although the examination of black-wingpad larvae with adult genitalia visible through the cuticle remains the mo st reliable means of specific identification, the rarity of this stage of the life cycle necessitates examination of the more abundant immat ure stages.
