60 Natura Somogyiensis resembling to eg. the well known species, Acheron trux (Walker, 1853) (Ábrahám 2008b). Female: Vertex covered with long dense reddish brown hairs. Frons shining dark brown with long dense dark brown hairs. Gena shining dark brown toward frons and shining yellow next to eye. Clypeus and labrum yellowish brown. Antenna brown, club yellow. Thorax dominantly reddish brown with as same colour hairs as on vertex. Wings rather wide as in Fig. 10. Length of fore wing: 42 mm, hind wing: 36 mm. Pterostigma narrow and faintly pigmented. Apical area beyond pterostigma also transparent or slightly pigmented as membrane. Legs light brown to dark brown. Tibial spurs as long as the length of segment 2 together. The examined female come from Mindano, a new record for the fauna of the Philippines, further males from Java (Indonesia) (van der Weele 1909, Navás 1913), SE China (Guangxi) (Wang et al. 2008b). Malesianus gen. n. Type species: Maezous harisi Ábrahám, 2008 Description When describing Malesianus harisi (Ábrahám, 2008) comb. n. was only two known female specimens therefore it has been combined to the closest and newly described genus, Maezous Ábrahám, 2008. The genus of Malesianus is characterized by sexual dimorphism. The apical area of wings of female Malesianus harisi is strongly concave below the tip, while that of male is pointed and only slightly concave. The species of Maezous are not typical of the sexual dimorphism in the wing shape. Malesianus male ectoproct is a pair of convex plate with papilla-like appendices, while that of Maezous has rather longer appendices. The mesothorax pattern of Malesianus is characterized by a longitudinal wide light middle band in dorsal view (Fig. 4), that of Maezous species are different, a very narrow longitudinal light middle line and a wide band (usually yellow) on each side can be seen (Fig. 3). Other morphological characters of the Malesianus are similar to the genus of Maezous (Ábrahám, 2008). Malesianus is distributed in Malesia, Malaysian archipelago. Malesianus harisi (Ábrahám, 2008) comb. n. - This species shows sexual dimorphism especially in the shape of wings and patterns (Fig. 2). The decription of the type material is based on two female specimens from Malaysia (Malay Peninsula and N Borneo, Sabah Prov.). The male and female can be recognized by their transparent pterostigma which clearly visible between the strongly brown pigmented costal and apical areas, by brown thorax with rather wide yellow median band (Fig. 4) and by the shining brown clypeus and the same colour labrum which has an indistinct small yellow mark in the middle. There was no visible pattern on the thorax of the type specimens because they were discoloured (Ábrahám 2008a). In males, the pigmentation in the costal area is similar to that of females but it restricts to the apical area on fore and hind wings (Fig. 2); the shape of male wings right below the apex is less concave than that of female. Length of fore wing: 37-39 mm and hind wing: 29-31 mm. In lateral view (Fig. 11) male ectoprocts with pair of convex plate and papilla-like ventro-caudal projection. Ventral and ventro-caudal margins with medium long and long bristles. Inner genitalia as in Figs 12-14. It is easily distinguished from the known Maezous species by the thorax pattern. The other known species, Maezous princeps, Maezous maezousi sp. n., Maezous jianfenglin-
