First record of the family Caliscelidae (Hemiptera: Fulgoroidea) from Madagascar, with description of new taxa from the Afrotropical Region and biogeographical notes Author Gnezdilov, Vladimir M. Author Bourgoin, Thierry text Zootaxa 2009 2020 1 36 journal article 10.5281/zenodo.274700 43f244af-481b-482a-999b-a27bce67894f 1175-5326 274700 Genus Signoreta gen. n. Type species: Signoreta victorina sp. n. Diagnosis (figs 1–3). Metope long and narrow, weakly enlarged before the clypeus, with distinct median and sublateral keels are joined apically. Median keel of metope extends to postclypeus. Ocelli present. Coryphe long and narrow, anterior margin acutely angulate, posterior margin straight, lateral margins keel-shaped. Face and coryphe covered by short hairs. Pronotum without keels, anterior margin strongly convex, with apex truncate. Scutellum without keels. Tegulae small. Fore wings long and narrow, not narrowing to rounded apex, without hypocostal plate. Basal cell small and narrow. Radius and median fused basally, radius trifurcate, median and cubitus anterior bifurcate (R 3 M 2 CuA 2), all longitudinal veins bifurcated distally, transverse veins are presented distally. Hind tibia with single lateral spine and six spines apically. First metatarsomere twice as long as second metatarsomere, each with two lateral spines apically. Etymology. The genus is named in honor of famous French entomologist Victor Signoret ( 1816–1889 ) who published the first comprehensive study on Hemiptera of Madagascar . It is feminine in gender. Comparison. The new genus differs from all other genera of the tribe by the absence of the nodal vein of the fore wings. The new genus has two lateral spines on the apex of the first metatarsomere like Symplanodes conjunctor Fennah, 1987 , but clearly differs from the latter by the structure of head.
