Abstract. Acanthalophus bicaudatus n. sp. from Sichuan, China, is described, illustrated, and compared with the Japanese species thus far known, from all four of which it readily differs by the separate mucros of elytra.
Abstract. The terrestrial isopods of Djibouti are still very poorly known. Two new species of Eubelidae are here described: Periscyphis ugoliniii n. sp. and Koweitoniscus agnellii n. sp. A third species is recorded, Periscyphis sudanensis Taiti, Ferrara & Allspach, 1997, previously known only from two localities in Sudan.
Abstract. Psylliodes urbaniae sp. nov. from Central Apennines (Italy) is described. Male genitalia and some biometric characters allow to distinguish between the new species and the very similar P. napi (Fabricius, 1792). Due to its limited distribution in mountain areas, its monophagy, and its subapterism, we propose possible processes leading to its differentiation.
