Type specimens of Neotropical Chrysopidae (Neuroptera) in Italian museums

Type specimens of Neotropical Chrysopidae are currently held in two Italian natural history museums. Four are in the Museo Regionale di Scienze Naturali (MRSN), Torino, and five are in the Museo Civico di Storia Naturale “Giacomo Doria” (MSNG), Genova. Together, these nine specimens also represent all of the known New World types of Chrysopidae housed in Italian museums. All were described by Longinos Navas between 1922 and 1932, and all are now in relatively good condition. Here, we catalog and provide images of each specimen, designate lectotypes, and offer current taxonomic and nomenclatural information on the species represented by each. Two nomenclatural changes are proposed: (1) Chrysopa mainerii Navas, 1929, previously considered incertae sedis, is synonymized with Ceraeochrysa everes (Banks, 1920), n. syn.; (2) Chrysopa barberina Navas, 1932, also previously incertae sedis, is identified as Chrysoperla barberina (Navas, 1932), n. comb.
