Subfamily Carventinae Description (New Zealand). Head. Genae large, produced anteriorly on either side of clypeus, nearly reaching or surpassing its apex to form a cleft or emarginate anterior margin of head. Rostrum short, not reaching beyond hind margin of head; bordered by bucculae at base; arising from a closed or open (Acaraptera, Lissaptera) atrium. Gula with rostral groove. Labrum fused with clypeus. Feeding stylets coiled into an anticlockwise circle. Thorax. Metathoracic scent gland openings inconspicuous, without well-developed evaporatory area. Tarsal claws with non-lamellate triangular (spatulate) pseudopulvilli. Abdomen. Dorsal mediotergites (dmtg) I–II at least partially fused, distinct from tergal disc (fused dmtg III–VI). Posterior margin of dorsal mediotergites (dmtg) III–V distinctly bent backward. Dorsal abdominal scent glands with first opening (or scar thereof) more developed than second and third. Pattern of apodemal markings 2:1:1 (dorsal, except 2:2: 1 in Acaraptera and Lissaptera); 2:2:1 (ventral, except 2:1: 1 in Leuraptera). Male genitalia. Pygophore trilobate (two dorsal lobes, one ventral lobe); parameres symmetrical; paratergites VIII strongly developed, projecting on each side of pygophore. References.
