Sobre el género Chrysopa Leach, 1815 de la Península Ibérica y Baleares (Insecta, Neuroptera: Chrysopidae)

New data are provided about the species of genus Chrysopa Leach, 1815 recorded in the Iberian Peninsula and the Balearic Islands. Regarding those species for which there were doubtful records or taxonomic questions, almost all the Iberian specimens were studied and compared with material coming from other areas to clarify these questions. So, their presence in Iberian-Balearic fauna, with the corresponding confirmation or correction of certain records, was verified, and the identity of some taxa (species and varieties) was elucidated. The validity of Chrysopa nierembergi Navas, 1908 regard to C. formosa Brauer, 1850 is confirmed, and its Lectotype is designated. Also the Lectotypes of Chrysopa nierembergi var. andreui Navas, 1910 and for Chrysopa nierembergi var. clara Navas, 1915 are designated. Both are considered synonyms of C. nierembergi. Only two of the Iberian records of Chrysopa phyllochroma Wesmael, 1841 are considered as valid, and the presence of Chrysopa dubitans Mclachlan, 1887 in the Iberian fauna is confirmed. The variety Chrysopa nierembergi var. nitens Navas, 1909 is considered as a valid species: Chrysopa nitens Navas, 1909 stat. prom., designating for her Lectotype. The external morphology and male genitalia characters of these five species are discussed, as well some diagnostic and comparative elements between them or with other nearby species. It commented and discussed some characters usually used in the identification of the species of the Chrysopidae family (variability and persistence of integumentary pigmentation of the specimens according to populations and time elapsed since their collection and conservation mode; dilated claws at their base or not). Finally, and until there is no new evidence, the alleged presence of Chrysopa abbreviata Curtis, 1834 and Chrysopa walkeri McLachlan, 1893 in the Iberian fauna is definitely ruled out, since it is based on inaccurate or inconsistent old quotations, not corroborated by new material. The genus Chrysopa is represented in the Iberian-Balearic fauna by ten species, of which the existing information is recorded and compiled, new material is provided, and the key of species of this genus and the maps of its distribution in the Iberian Peninsula and the Balearic Islands are updated.
