the body. The eggs can be more arched on the dorsal side and often have short hairs. The micropylar plate has three arms, with one arm pointing towards the lid, while the other two run more or less circularly around the egg. The eggs are usually laid on the ground, clamped in the bark near the ground or attached to plants such as mosses. Taxonomy In 1875 Carl Stål established the genus Pylaemenes for some species that were previously listed in the genus Acanthoderus. Of the species originally rearranged by him, only Pylaemenes coronatus remained in the genus. All others have turned out to be synonyms to other species or have turned out to be representatives of other genera. As namesake, Stål chose the Paphlagonian king Pylaemenes, a figure from Greek mythology. Since he had not specified a type species, William Forsell Kirby chose Pylaemenes coronatus in 1904, the oldest species listed in the genus at that time, which is still the type species. In the same publication in which he described the genus Pylaemenes, Stål established 1875 the genus Datames for Acanthoderus mouhotii (today Orestes mouhotii) and Acanthoderus oileus, which he named after the Old Persian military leader Datames. James Abram Garfield Rehn specified Datames oileus in 1904 as type species of Datames. In the following years almost all newly described species were assigned to this genus. Frank H. Hennemann discovered in 1998 that the type species Datames oileus belongs to the genus Pylaemenes. He synonymed Datames and transferred all species that had previously belonged to Datames into the genus Pylaemenes. In the revision of the genus Orestes and the description of six new species in this previously monotypic genus by Joachim Bresseel and Jérôme Constant in 2018, three species belonging to Pylaemenes were also transferred to the genus Orestes. In addition, the differentiation between the genera Orestes and Pylaemenes has been specified. Following this, some of the species described in Pylaemenes in the recent past belong into the genus Orestes, such as Pylaemenes elenamikhailorum, Pylaemenes konchurangensis and Pylaemenes konkakinhensis . A Species described by Thanasinchayakul in 2006 as Pylaemenes kasetsartii was not recognized by the ICZN Commission and has been listed as nomen nudum since 2019. In their genetic analysis study published in 2021 shows Sarah Bank et al. that the Pylaemenes species examined there cannot be assigned to a uniform clade. The three examined species occurring on
