Hybrizon buccatus (DE BREBISSON, 1825)

Paxylomma buccata DE BREBISSON, 1825: 23. Type lost.

R e d e s c r i p t i o n: Front wing 2.9 mm, body 3.6 mm, ovipositor sheath 0.4 mm long ( Figure 1 ). Head transversal, strongly narrowed behind, 2.25 as wide as long ( Figure 2a ). Ocelli large and prominent, its diameter almost twice (7:4) as long as distance between lateral ocellus and eye. Eye without hairs. Occipital carina connected hypostomal carina far from the base of mandible. Scapus somewhat shorter than pedicellus. Flagellum 11 segmented, first segment 8.6 as long as wide and last segment 5.5 as long as wide. Inner eye orbit strongly convergent downwards. Face almost square. Clypeus naseform. Front tentorial pits large. Mandible small and obscured by prominent maxilla ( Figure 2b ).

Mesosoma very short, 0.9 as long as high. Epomia and sternaulus absent. Mesonotum wider than long (15:14). Notaulus not developed, but on its place mesonotum with pair of bands of distinct punctures. Prescutellar groove deep and large ( Figure 2c ). Scutellum carinated only basally. Prepectal carina strong but developed only ventrally. Mesosternum bilobed, with deep mesosternal suture. Postpectal carina absent. Basal cell of front wing largely glabrous, with at most of 15 setae. First radial vein in front wing issued close to base of pterostigma ( Figure 2d ). Hind wing with 3 distal hamuli. Legs very slender, hind tarsal segments swollen. Hind coxa about 7.0 as long as wide in lateral view. Hind femur about 9.0 as long as wide ( Figure 2e ). Correlation between length of hind tarsal segments as 35:12:8:5:6. Propodeum with longitudinal dorsal and pleural carina well developed ( Figure 2f ). Lateral carina as a trace on the middle. Propodeal spiracle elongated, closer to lateral than to pleural carina. Abdominal hole of propodeum separated from hind coxa sack by wide space.

Metasoma with first segment 0.5 as long as second tergum. Apical half of postpetiolus and second tergum on basal half coarsely striated longitudinally ( Fig. 2g ). Second and

third metasomal terga connected flexibly. Apical half of metasoma compressed. Ovipositor gradually tapered to apex, without subapical dorsal notch.

Head and lateral parts of face with granulate sculpture. Mesonotum and scutellum smooth with very rare punctures. Lower half of mesopleuron and metapleuron shagreened.

Black brown; scapus and pedicellus from below, clypeus, palpi, tegula, front and middle coxa and hind coxa from below whitish yellow; legs including upper surface of hind coxa red brown.

Male. Head except face and propodeum dark brown. In other as in female.
