ÁBRAHÁM LEVENTE: Ascalaphid Studies VI. New genus and species from Asia with comments on genus Suhpalacsa (Neuroptera: Ascalaphidae)

ASCALAPHID STUDIES VI. 71 Abdomen: 32-34 mm long. Tergite 1 divided dorsally; brown with, long, soft and brownish hairs. Tergites brown with yellow indistinct median band. Tergite 2 as long as wide with moderately long, stiff pointed black setae dorsally and short lateral black setae. Tergites 3-4 long and bare with short, stiff and black setae laterally. Sternites yellow to brown. Setae on sternites short, shinning and white (may be meal-like powder present on last segments). Genitalia: Tergite 8 triangular-shaped and brown. Tergite 9 small, subrhomboid-shaped; brown and covered with sparse short setae. Caudoventral apex acute with 3-5 long stiff and black setae. Ectoprocts subrhomboid-shaped, lateroventral projections three times longer than wide. Ectoprocts with dense, short and silky hairs on caudal margin and its projections with long, stiff and black hairs curved caudally (Fig. 3). Sternite 9 pentagonal-shaped, brown and covered with short, stiff and black setae. Gonarcus elongated, arch-like, fused with parameres. Caudal margins of parameres serrated. Pelta small. Pulvini bag-like with moderately long gonosetae. HABITAT and DISTRIBUTION: Forests, known only from Laos (Fig. 6). Etymology: The new species is dedicated to my children, Tamás Á. and Janka Á. DIAGNOSIS The new species resembles to Maezous princeps (Gerstaecker, 1893) (=Suhpalacsa princeps Gerstaecker, 1893) comb. n. The main differences are: Male ectoproct projection in M. tomijankae longer than that in M. princeps (Fig. 4). Pterostigma of M. princeps brown but that of M. tomijankae yellow (Fig. 5). Sides of M. princeps with brown pattern while its M. tomijankae entirely yellowish. Maezous princeps has been known from Java. This is the first time to report it from the continental Asia. New localities are: South China, Laos and Thailand. The new species also resembles to other three species namely Suhpalacsa jiangfanglingana (Yang, 2002), (=Acheron jiangfanglingana Yang, 2002), Suhpalacsa fuscomarginata Wang et Sun, 2008 and Suhpalacsa fumiala Wang et Sun, 2008 described recently but it also differs from those in colouration of pterostigma and projection length of male ectoprocts. Pterostigma of M. tomijankae is yellow and it has the longest projection of ectoprocts of all three species mentioned. Certainly, these species shall also be combined with Maezous gen. n. Maezous harisi sp. nov. Material examined: Holotype: Ç Malaysia, Borneo, Prov. Sabah, Poring, N6°02', E116°42'; 1-6. 5. 2006. Leg. B.
