ÁBRAHÁM LEVENTE: Ascalaphid Studies VI. New genus and species from Asia with comments on genus Suhpalacsa (Neuroptera: Ascalaphidae)
70 LEVENTE ÁBRAHÁM McLachlan, 1871, known from Madagascar, was moved to genus Suphalomitus by VAN DER WEELE (1909), however I suppose, this species represents a new genus, which is close to Proctarrelabris Lefébvre, 1842. From Australia and New Caledonia, 21 Suhpalacsa species were described. After a generic revision (NEW 1984), 15 valid Suhpalacsa species remained; the other 6 species were replaced into genera Megacmonotus New, 1984, Pilacmonotus New, 1984 and Suphalomitus. Originally 21 Suhpalacsa species were described from Asia. Later, three of them were replaced into genera Ascalaphus Fabricius, 1775 and Suphalomitus. Several Suhpalcsa species were found in Asia which are supposed to be synonyms of other species therefore species level revision will be necessary. Suphalacsa fuscostigma Navás, 1925 is a nomen dubium. The genus Suhpalacsa (type species: S. flavipes (Leach, 1814) from Australia) is characterized by narrow, elongate wings, parallel costal and inner margins and straight or slightly curved anal forewing area (NEW 1984). The new genus close to Suhpalacsa but differs in elongate and triangle-shaped wings, both wing-margins are unparallel, male ectropocts with shorter or longer ventrolateral projections. The new genus is supposed to be widespread in SE Asia and Malaysian archipelago. Probably most Suhpalacsa species reported from this area shall be placed into the new genus. KEY TO THE GENERA 1. Pterostigma longer than wide, hindwing boaderthan forewing, relatively short and not extending beyond pterostigma of forewing Suphalomitus - Pterostigma short, about as long as wide; hindwing about as wide as forewing and usually slightly 2 2. Anal margin of forewing obtuse; male ectoprocts without lateral projections (spread in Australia) Suhpalacsa -Anal margin of forewing rounded or acute; male ectoprocts with lateral projections (spread in Asia) Maezous gen. n. Etymology. The new genus is dedicated to Prof. Dr. Zoltán Mészáros, Hungarian entomologist (his nickname is MéZo, read Maezo). Maezous tomijankae sp. nov. Material examined: Holotype: S Laos, Prov.

Sausa Deposited: Entomological Collection of Somogy County Museum, Kaposvár DESCRIPTION Male (Fig. 1) Head: Vertex yellow, covered with long, dense, shinning pale yellow pubescence that sporadically mixed with brown hairs. Dorsal part of frons shinning brown, ventral part yellow with short soft and pale yellow hairs. Long tufts of pale yellow hairs on clypeo-genal inflection directed distally. Genae yellow to brown, hairless. Clypeus and labrum yellow. Lateral and dorsal parts of clypeus with sparse short brown hairs. Ventral margin of labrum with short, sparse, silky and ochraceous hairs curved to mouthparts. Mandible yellow with black apex. Maxillar and labial palpi ochraceous. Palpar segments with long, sparse and yellowish hairs. Apical 2 palpar joints with sporadic stiff and black setae. Occiput and postorbital sclerite yellow and hairless. Eyes medium size divided by suture-like inflection transversally. Antenna 25-26 mm, 2/3* shorter than distance between base of forewing and pterostigma. Scape and pedicel yellow with long, dense and pale yellow pubescence mixed with sporadic brown hairs. Middle part of flagellar segments longer than basal and apical parts of segments, bare. Flagellar segments broadened at joins. Club yellow and brown, annulated with short, black smoothing verticals; subglobular-shaped with flattened apex. Bristle of club brown. Thorax: Pronotum narrow and yellow with short yellowish hairs. Both pronotal margins flexed upwards. Lateral projection brown with long, dense and brown hairs. Mesonotum brown with narrow yellow median line widened distally and two wide yellow lateral bands. Metanotum brown with indistinct central yellowish band. Notum with sparse, shinning greyish hairs. Sides of mesonotum unicolour yellow with short soft and white hairs. Legs: Coxa, trochanter and femur yellow with soft and yellowish hairs. Ventral side of femora with sporadic long, black and stiff bristles. Tibiae and tarsi dark brown with stiff, shinning and black bristles. Tarsal segments 1-4 equal; segment 5 as long as segments 1-4 combined. Tibial spurs reddish-brown somewhat longer than segment 1. Claws reddish-brown. Wings: Forewing: 32-33 mm long and 9 mm wide. Hindwing: 28-29 mm long and 7.5 mm wide. Membrane transparent with light brown shadow. Costal and apical area of membrane tinged with brown shadow that extended into first cell row of radial area. Pterostigma longer than wide, hyaline with 4 yellow cross veins. C, Sc and R veins proximally brownish, distally yellow. Other longitudinal veins yellow, cross veins yellow to brown. C with short dense smoothing black setae. Setae on other veins sparse and black. Apical area beyond vein Sc+R with three rows of cells. In front of origin of Rs, 8-9 radial cross-veins took place in forewing and 6-7 in hindwing. Colouration of hindwing similar to forewing. Hind pterostigma with 3 cross-veins. Ambient vein on anal area with long soft and brown hairs.
