First record of a cavernicolous Kinnaridae from the Old World (Hemiptera, Auchenorrhyncha, Fulgoromorpha, Kinnaridae, Adolendini) provides testimony of an ancient fauna
(2021) Hoch, Hannelore; Sendra, Alberto; Montagud, Sergio; Teruel, Santiago; Ferreira, Rodrigo Lopes
A new obligately cavernicolous species in the planthopper family Kinnaridae is described from Spain. This is the first record of a cavernicolous kinnarid from the Old World, and the first record of a troglobitic fulgoromorphan hemipteran from mainland Spain, and also the 7th cavernicolous kinnarid species world-wide. Epigean Kinnaridae are not known from the present-day fauna of the Iberian Peninsula nor from Western Europe at large. The new species is regarded as a relict from an ancient fauna which is now ex-tinct. The new cavernicolous species could not be assigned to any of the existing genera, thus a new genus is established. Molecular data (COI barcode sequence) for the new species are presented. For the first time, a detailed description of the nymphal morphology of a kinnarid is provided. Information on its ecology, behaviour, distribution and conservation status is given, and biogeographic implications are discussed.

Three new species of the genus Speocera (Araneae: Ochyroceratidae) from caves of the state of Minas Gerais, Brazil
(2023-10-20) Brescovit, Antonio ; Zampaulo, Robson de Almeida ; Pedroso, Leandro; Cizauskas, Igor
Three new species of the spider genus Speocera Berland, 1914 are described from caves of different lithologies, in the state of Minas Gerais, Brazil: Speocera canjica n. sp., S. pamonha n. sp. and S. vacaatolada n. sp., all based on males and females. Among the described species, S. vacaatolada n. sp., presents a palp morphology similar to that of Speocera pallida, where a reduction of bulb structures occurs.
