The species of Lampetis (Spinthoptera) Casey, 1909 of Central America, North America and the West Indies are revised and 31 species are recognized. Six species from the West Indies [L. aurata (Saunders, 1871), L. aurifera (Olivier, 1790), L. bahamica (Fisher, 1925), L. guildini (Laporte & Gory, 1836), L. straba (Chevrolat, 1867), and L. torquata (Dalman, 1823)], eight species from Mexico [L. auropunctata (Kerremans, 1893) (new record for the USA), L. chalconota (Waterhouse, 1882), L. christophi Théry, 1923, L. dilaticollis (Waterhouse, 1882), L. geniculata (Waterhouse, 1889), L. granulifera (Laporte & Gory, 1837), L. mexicana Théry, 1923, and L. obscura Thomson, 1879], three species from Mexico and Central America [L. cortesi (Laporte & Gory, 1837), L. monilis (Chevrolat, 1834), L. simplex (Waterhouse, 1882)], and three from Central America [L. hirtomaculata (Herbst, 1801) = L. insularis (Casey, 1909) syn. n.; L. lesnei (Kerremans, 1910); and L. srdinkoana (Obenberger, 1924)] are redescribed. Seven new species (L. chamela sp. n., L. colima sp. n., L. cyanitarsis sp. n., L. hondurensis sp. n., L. tigrina sp. n., L. viridicolor sp. n., and L. viridimarginalis sp. n.) are described. Three species from Mexico and the United States [L. cupreopunctata (Schaeffer, 1905), L. drummondi (Laporte & Gory, 1836), and L. webbii (LeConte, 1858)], and one species from Mexico (L. chiapaneca Corona, 2004) are not described here, because they were (re)described recently. The diagnosis, distribution, host plants and phenology data of L. chiapaneca, L. cupreopunctata, L. drummondi, and L. webbii are given. Lampetis famula Chevrolat, 1838 and L. variolosa (Fabricius, 1801) are not recognized herein as Mexican species, because they are from South America according to the literature and specimens studied. Information on variation, distribution, and host plants are given for each species. Photographs of dorsal habitus and male genitalia are included.
The genus Xyalophora (Giraud, 1860) is revised herein. The revision includes the type species of Xyalophora (Figites clavatus Giraud, 1860), the type material and the original descriptions of all the species of Xyalophora included in the Weld catalogue, and long series of undetermined material. Xyalophora clavata (Giraud, 1860) and X. singularis (Ashmead, 1896) are the only currently recognized species that should be included in Xyalophora. Four new species are described: X. belizini sp. n., X. giraudi sp. n., X. provancheri sp. n. and X. zarazagai sp. n. The type species of Ceraspidia, Ceraspidia japonica Belizin, 1952, corresponds to males of a species within Xyalophora. Thus, Ceraspidia is a new synonymy of Xyalophora, which results in Xyalophora japonica comb. n. Xyalophora impatiens (Say, 1836) and Xyalophora picea (Spinola, 1853) being considered like incertae sedis, as the latter does not belong to the Figitinae but to the Eucoilinae and is probably a species within Acantheucoela Ashmead, 1900. Xyalophora aciculata Benoit, 1956 is transferred to the genus Figites Latreille, 1802: Figites aciculata comb. n. Xyalophora leviventris Kieffer, 1908 is a synonym of Xyalophora quinquelineata (Say, 1836), which is transferred to Xyalophoroides gen. n., a new genus here described. The differences between all the genera of Figitinae with a scutellar spine are discussed and illustrated.
We review the cicada genus Auritibicen Lee, 2015 based on the description of ten new species: A. aethus sp. n., A. daoxianensis sp. n., A. pallidus sp. n., A. rotundus sp. n., A. curvatus sp. n., A. purus sp. n., A. parvus sp. n., A. gracilis sp. n., A. septatus sp. n. and A. lijiangensis sp. n. Auritibicen shikokuanus (Kato, 1959) is confirmed to be a synonym of Auritibicen kyushyuensis (Kato, 1926). Diagnoses and descriptions, along with illustrations of the structure of male genitalia, are provided for all Auritibicen species. The systematics of Auritibicen is elucidated using both morphological and molecular characterization. Thirty-five morphological characters of the 24 species of Auritibicen and one outgroup taxon, Chremistica ochracea (Walker, 1850), were scored. Morphological phylogenetic analyses reveal the relationships among related species of Auritibicen, which are supported by a number of morphological characters. The mitochondrial gene fragments of Cytochrome Oxidase I (COI) of 11 species of Auritibicen and two outgroup Lyristes species were analyzed and yielded identical robust phylogenetic trees. The phylogram based on a Bayesian analysis of both morphological and molecular data is similar to the ML/BI topologies based only on the molecular data. The molecular phylogenetic analysis indicates that species of Auritibicen are structured phylogeographically, with related species clustered into three lineages. The divergence time estimated based on molecular data indicates that the divergence of Auritibicen from Lyristes occurred during the Miocene, and the most recent common ancestor (tMRCA) of Auritibicen evolved during the Pliocene. However, the time when the main divergence events of species of Auritibicen occurred was the Pleistocene. From the combination of the phylogeny and updated geographical distributions, we infer that the center of distribution of Auritibicen could be Southwest China (e.g., Sichuan and Yunnan Provinces), from where species of this genus spreaded northeastwards to Shaanxi, Hubei and other provinces along the Qinling and Daba Mountains, then further northeastwards to Hebei Province in China and also to Far East Russia, the Korean Penisula, and Japan.
