Argaman, Q.: Generic synopsis of Myzinidae (Hymenoptera: Scolioidea)

purple hairs. Abdominal terga clothed with arcualely bent setulae which are laterally flattened; of purple black color and steel bluish iridescence. Antenna, mandible, ventral and lateral aspect of body, legs and declivity of first tergum clothed with erect silver white hairs. Head dorso-ventrally flattened; quite as long as wide. Eye 0.38X as long as head, 0.95X as distance between eye tops and vertex crest, 1.35X longer than wide. Width of front, at minimum distance between eyes, 0.75X width of head, 2.IX length of eye. Temples almost parallel, insignificantly converge toward occiput, postero-lateral comers broadly rounded, so that the occipital margin straight on a very short distance medially. Clypeus vertical, apically truncate and bordered by a fairly emerging ridge, without differentiated median lobe or keel. Mandible parallel-sided, provided with an apical ventral tooth, a somewhat blunt one above it, and a very conspicuous grip-like tooth on upper, apical inner margin; inner border provided with 5-6 minute, triangular serrations (Fig. 47). Medio-dorsal keel indistinct; ventral aspect of mandible with a strong, straight keel developed from base to apex. I was able to detect only one small segment both on maxillary and labial palpus. Hypostomal notch half as long as postgenal bridge. Occipital carina not developed except very subtly, on a short distance, at postero-ventral comer of head. Malar space narrow, linear. Surface of head definitively alutaceous; covered with irregular rows of punctures, both with small and large interpunctal spaces occurring here and there. Median ocellus situated between inner orbits, lateral ocelli behind; front angle of ocellar triangle scarcely greater than right angle; ocelli minute, smaller than diameter of setigerous punctures; each bordered inwardly by a black spot. OOL = 2X POL. Antenna! tubercles consolidated in a frontal lobe, shallowly bisinuate apically. Scape 2X as long as wide; flagellum cylindrical, shiny, almost entirely glabrous, segments almost equal, about 1.5X as long as thick. Pronotum rectangular, as long as wide. Mesoscutum reduced to a transverse furrow. Scutellum large, convex. Metanotum in form of a shining ridge. Propodeum ovoidal, converging both anteriorly and posteriorly. Surface of pronotum and propodeum lengthwise crested, costulae undulate and intermixed with large setigerous punctures. Lateral propodeum wholly, delicately and densely, longitudinally costulate. Apterous, tegula extremely small. Legs normal, nowhere inflated; mid and hind tibia spinulose; fore tarsi with a rather short rake. Tibial spur formula 1-2-2, spurs tapering toward apex. Claws bidentate but inner tooth very small, nearly indistinct. Last segment of hind tarsi exactly as long as penultimate. First tergum globular, 2-5 transverse, sixth triangular. Second tergum with a weak basal gradulus. Surface of abdomen sculptate like thorax, except the costulae very often fragmented in papillae. Last tergum and all sterna alutaceous. No specialized pygidial area. Male and biology unknown. Material: Holotype female, intact specimen on recticard, from Cameroon, labelled: "Guetale, Cam. NONVLL. IV. 1970". - Paratypes, all from Cameroon: 1 female topotypic and same data; 1 female "Bogo, Cam. X. 1963"; 15 females "Mora, Cam., Guetale", X. 1964, XI. 1967, I. 1970, IV. 1970, IV. 1971, III-VI. 1971. Holotype and 4 paratypes are deposited in Coll. Prof. G. NONVEILLER, Zemun. Two paratypes in each of the following collections: Hungarian Natural History Museum, Budapest; Hym. Typ Nos. 6960, 6961; National Museum of Natural History, Washington, DC; Museum d'Histoire Naturelle, Paris; Museo Civico di Storia Naturale, Genova; Zoologisk Museum, Copenhagen; Tel Aviv University, Tel Aviv; one paratype in Coll. ARGAMAN. Variation: Size varies between 4.7-8.2 mm. In small specimens front strongly infuscated, brownish, while vertex became orange to light yellow. One female differs from the holotype in having frontal lobe spotted with white, on each side basally. Another female has a small white spot on left side of third tergum. One with a small spot on left side of fourth tergum. Two females have a small white spot on both side of fourth tergum; and one female have four white spots in a line on fourth tergum. All these spotted specimens were collected at Mora. Tilkuya arcuata (FISCHER DE WALDHEIM), comb. n. (Fig. 46) Myzine arcuata FISCHER DE WALDHEIM, 1843, Magas, de Zool. 13:122, male. Locus classicus: "Russia meridionalis". Male. Length 12.0 mm, length of forewing 8.3 mm. Body black, with the following parts pale sulphur yellow: clypeus except a narrow apical rim, mandible except apical teeth, a narrow transverse stripe on inner aspect of scape, a pair of anterior spots and a posterior stripe of pronotum, tegula, a triangular spot on mesopleuron above, a rather small spot on each coxa ventrally, precoxal lobes of mesosternum, legs entirely except base of femora and an inner spot on tibiae, an apical broad stripe on terga 1-6 and sterna 2-6, and a pair of lateral spots on last terga. Apical teeth of mandible piceous. Body clothed with glittering white pubescence, not decumbent. Wings hyaline, vitreous, pubescence of wing membrane dark, veins dark brown, pterostigma orange. Head circular in outline, practically as high as wide. Inner orbits slightly diverging above, deeply emarginate within. Eye 1.7X as long as wide. Clypeus convex, apex shallowly emarginate; surface with moderately dense punctures. Front densely punctate, interspaces narrow, mere septa. Vertex sparsely punctate, punctures dimpled. Front angle of ocellar triangle right angle; OOL = 1.4X POL. Occipital carina complete. Frontal lobe slightly emarginate
