Le genre Chrysopophthorus : trois espèces paléarctiques, endo-parasites "
koinobiontes" de chrysopes adultes
The biological range has been investigated by Séméria (1976); C. hungarica (Zilahi-Kiss) was reared only from Chrysoperla carnea (Stephens, 1836) and Mallada (= Anisochrysa; Brooks & Barnard, 1990) spp. (i.e. M.flavifrons (Brauer, 1851), M. genei (Rambur, 1842), M. ibérica (Navas, 1903), and M. picteti (MacLachlan, 1880)) and not from (four) Chrysopa spp. The only other species reared is Chrysopophthorus elegans Tobias, 1961, which has been reared from Chrysoperla carnea (Stephens) (Tobias, 1986). According to Principi et al. (1979), Mallada clathrata (Schneider, 1845) and M . prasina (Burmeister, 1839) are also parasitized. Both sexes of adult Chrysopinae are attacked; often unsuccessfully, because of the defense reaction of the adult host. The larva emerges from the apical part of the abdomen of the host, moults (leaving the exuvia partly in the host), and has no external feeding phase. It crawls away from the host in search of a place suitable for spinning its cocoon; the cocoon is elongate, thick-walled and white. The host may remain alive after the parasite has emerged and females remain even capable of laying eggs (Principi et a l , 1979).
La clé, dont je ne peux me dépatouiller hors connexion car je ne sais pas ce que sont les "
anterior tentorial pits"
1. Distance between anterior tentorial pits about 0.9 times minimum width of face; margin of clypeus evenly curved medio-ventrally => C. elegans Tobias
Distance between anterior tentorial pits 0.5-0.7 times minimum width of face (figs 5,16); margin of clypeus slightly concave or straight medio-ventrally (figs 5,
16) => 2
2. Second submarginal cell of fore wing sessile (fig. 4); first metasomal tergite distinctly widened apically, its length 3.6-5.6 times its apical width (fig. 9), exceptionally longer; vein SRI of fore wing slightly curved (fig. 4); vein lr-m of hind wing somewhat shorter than vein 1-M (fig. 4); sixth segment of maxillary palp about as long as fifth segment; temple in dorsal view somewhat shorter, compared to length of eye (fig. 3); penultimate segment of antenna of 9 robust, about 1.5 times as long as wide (figs 1, 2); propodeum reticulate medio-posteriorly (fig. 8); middle lobe of mesoscutum similarly sculptured as lateral lobes (fig. 8); notauli shallow, usually narrow and without wide rugose area posteriorly (fig. 8) => C. hungaricus (Zilahi-Kiss)
Second submarginal cell of fore wing long petiolate (fig. 11); first tergite hardly widened apically, its length about 7 times its apical width (fig. 18); vein SRI of fore wing distinctly curved (fig. 11); vein l r -m of hind wing about as long as vein 1-M (fig. 11); sixth segment of maxillary palp about twice as long as fifth segment (fig. 17); temple in dorsal view somewhat longer, compared to length of eye (fig. 16); penultimate segment of antenna of 2 less robust, at least twice as long as wide (figs 12,15); propodeum smooth medio-posteriorly (fig. 14); middle lobe of mesoscutum much denser sculptured than lateral lobes (fig. 14); notauli deep, wide, with wide rugose area posteriorly (fig. 14) => C. petiolus Chou
