Beschreibungen/Notizen

• Lineostethus Ruckes, 1966 has four species, L.clypeatus (Stål, 1862), L.graziae Hildebrand & Becker, 1982, L.marginellus (Stål, 1872), and L.tenebricornis (Ruckes, 1957); mostly restricted to Central America, but with distribution records in the southern North America. Lineostethus is one of the discocephaline genera with discoid head. The last review of the genus, from the 1980’s, focused on the genital morphology and failed to provide updated descriptions or a key to species. We had access to material from different collections, including several specimens representing new species of Lineostethus , and males of L.marginellus which shows important variations in genital morphology. Here we update the generic description of Lineostethus and its known species and describe the new species Lineostethusacuminatus sp. nov. (holotype male in DZUP: Costa Rica, Guanacaste), Lineostethusauritus sp. nov. (holotype male in AMNH: Mexico, Oaxaca), Lineostethusotarus sp. nov. (holotype male in AMNH: Mexico, Michoacán) and Lineostethussinuosus sp. nov. (holotype male in DZUP: Mexico, Yucatán). Additionally, we provide identification keys and distribution maps.
