Figure 4. A–C in Phylogeny of Chrysopidae (Neuroptera), with emphasis on morphological trait evolution

Figure 4. A–C, photomicrographs of flagella, lateral view; curved lines indicate the base of the flagellar setae, and black arrows indicate the tip of the flagellar setae. A, Hypochrysa elegans, five setal rings. B, Nothochrysa sp., six setal rings. C, Peyerimhoffina gracilis, four setal rings. D, E, photomicrographs of the meso- and metanotum, dorsal view. D, Hypochrysa elegans, black arrow indicates the presence of a small expansion on the anterior margin of the metascutum. E, Chrysopa oculata, black arrow indicates the simple metascutum, without medial expansion. F, G, photomicrographs of tarsi. F, Hypochrysa elegans, dorsal view, black arrows indicating four long setae. G, Stigmachrysa kervillei, dorsal view, black arrows indicating two long setae.
