Diagnosis

(adapted from Brooks and Barnard 1990). Small to medium-sized green lacewings, body generally pale green. Head narrow (head width: eye width = 1.9-2.6: 1), marked with black or red stripes on clypeus, gena or frons; maxillary palp and labial palp narrow, elongate apically; antenna nearly as long as forewing. Pronotum narrow, sometimes marked with black lateral spot, and with pale long fine setae; meso- and metanotum sometimes with broad black markings. Legs with protibia and mesotibia often marked with spots at median portion; metatibia seldom marked. Forewing broad (length: width = 2.1-2.5: 1); marked with large black or brown spots or suffusion; costal space broad near wing base; costal vein with erect long setae; Sc very short; pterostigma often with black spots; Subcosta (Sc) and Radius (R) closely spaced; first intramedian cell present; two gradate series of crossveins present, slightly divergent anteriad, basal inner gradate series meeting Psm; veins not crassate in male. Hind wing narrow (length: width = 3.0-4.0: 1). Abdomen with sparse, long setae, with terga often marked; callus cerci ovoid; both male and female ectoprocts fused dorsally with slight dorsal invagination; male sterna 8+9 fused, microtholi absent. Female sternum 7 posteriorly truncate in ventral view with small setose apical tubercle.
