Lectotype designations and nomenclatural changes in Xylographus Mellié (Coleoptera, Ciidae).

We designate lectotypes and propose nomenclatural changes in Xylographus Mellié (Coleoptera, Ciidae) based on type specimens deposited in the Museum of Comparative Zoology (USA), Museum für Naturkunde Berlin (Germany), the Natural History Museum (UK), Muséum d'Histoire Naturelle de la Ville de Genève (Switzerland), Muséum National d'Histoire Naturelle (France), Naturhistoriska Riksmuseet (Sweden) and Naturhistorisches Museum Wien (Austria). We designate lectotypes for the following species: Cis fultoni Broun, 1886, Xylographus anthracinus Mellié, 1849, X. bicolor Pic, 1916, X. brasiliensis Pic, 1916, X. ceylonicus Ancey, 1876, X. contractus Mellié, 1849, X. corpulentus Mellié, 1849, X. dentatus Pic, 1922, X. gibbus Mellié, 1849, X. hypocritus Mellié, 1849, X. javanus Pic, 1937, X. lemoulti Pic, 1916, X. longicollis Pic, 1922, X. madagascariensis Mellié, 1849, X. nitidissimus Pic, 1916, X. perforatus Gerstaecker, 1871, X. porcus Gorham, 1886, X. punctatus Mellié, 1849, X. ritsemai Pic, 1921, X. rufescens Pic, 1921, X. rufipennis Pic, 1934, X. rufipes Pic, 1930, X. seychellensis Scott, 1926, X. subopacus Pic, 1929, X. subsinuatus Pic, 1916, X. suillus Gorham, 1886, X. testaceitarsis Pic, 1916 and X. tomicoides Reitter, 1902. We propose the following syn. n. (senior synonym listed first): X. anthracinus = X. testaceitarsis, X. brasiliensis = X. lucasi Lopes-Andrade & Zacaro, X. corpulentus = X. lemoulti and X. richardi Mellié, X. madagascariensis = X. eichelbaumi Reitter, X. rufipennis, X. seychellensis Scott and X. tarsalis Fåhraeus, X. nitidissimus = X. longicollis, X. subsinuatus = X. rufescens. We exclude three species from Xylographus: Cis renominatus, nom. n. (for X. dentatus Pic, 1922, not C. dentatus Mellié, 1849), Paratrichapus fultoni (Broun, 1886), comb. n. and P. javanus (Pic, 1937), comb. n.

Two new Neotropical species of Ceracis Mellié (Coleoptera, Ciidae) and redefinition of the cucullatus group.

Two new Neotropical species of Ceracis Mellié are described: Ceracis cassumbensis Antunes-Carvalho & Lopes-Andrade, sp. n. from a single locality in northeastern Brazil and Ceracis navarretei Antunes-Carvalho & Lopes-Andrade, sp. n. from a single locality in southern Mexico. Scanning Electron Microscope images of adults and photographs of holotypes and male terminalia are provided for both species, their similarities and differences with other Ceracis are briefly discussed, and the cucullatus species-group is redefined for including the new species described herein.
