Acanthaegilips diazi Ros-Farré & Pujade-Villar sp. n.

( Figs. 1F , 3F )

Studied material – 3; unknown. Holotype: 1 ( MLP) 16-11-81 at San Javier, San Miguel de Tucumán, Tucumán ( República Argentina) S. Mulvany, N. Díaz, G. Armesto, P. Fidalgo col. Paratypes: 2, Same Holotype’s data .

Etymology – This name was chosen to honour Dra. Norma Beatriz Díaz, Argentina, who loaned us all type specimens of this species.

Length of head + mesosoma + metasoma: 2.9 mm to 3.4 mm.

Colour – Head black, mesosoma black with exception of the lateroventral margins of pronotum, the anterior and lateral margins of mesoscutum, the mesopleural triangle and the notauli, which sometimes are red or amber colour. Metasoma blackish brown. Pedicel reddish brown, scape and F1 to F5 or F6 black to blackish brown with reddish colour on the apex, following flagellomeres changing to light brown. Mandibles light brown with medium brown teeth. Legs yellow with exception of the last ones, which are dark to medium brown.

Head – Covered by quite dense long pubescence. Malar furrow slightly curved, in upper part strongly curved. Postocular furrow absent. Occipital carina present. Malar space 0.61 to 0.65 times the height of the compound eye. Transfacial line 0.51 to 0.52 times the greatest width of the head and 1.07 to 1.10 times the height of a com- pound eye. Pleurostomal lines weak. Antennal foramina separated from each other by 1.20 to 1.25 times the distance between the foramen and the compound eye.

Antennae – Flagellomeres cylindrical. Length of F1 1.46 the length of F2. Scape and pedicel with sparse pubescence. Flagellomeres covered with short dense pubescence. Antennal formula: 16 (5.5): 5 (4): 22 (3.5): 15 (3.5): 14 (4): 14 (3.5): 12 (3.5): 12 (3.5): 12 (3.5): 11.8 (3.3): 10 (3.3): 9.5 (3.2): 8.5 (3.5): 14 (3). Placodeal sensilla start on F1 but they are dorsally absent from F1 to F5; Sensilla are very sparse on dorsal part of F6 and F7. F3 to F5 slightly expanded dorsolaterally with a longitudinal ridge on the raised part.

Mesosoma – Anterior pronotal plate rounded dorsally ( Fig. 1F ) with quite dense pubescence at the lateral areas and sparse pubescence in lateroanterior margins, near the dorsal margin weakly transversely carinulate. Lateral face of pronotum with dense long pubescence, the sculpture is between rugose and areolate. Mesoscutum in lateral view 1.69 to 2.03 times higher than long; in dorsal view 1.24 to 1.27 times wider than long. Median mesoscutal impression very short as long as broad. Notauli complete and well differentiated. The areolate sculpture of the mesoscutum is laterally effaced, in some specimens is weak in medial part ( Figs. 1F , 3F ). There is a very conspicuous line of hairs on the anterior and lateral margins of the mesoscutum. Scutellum in dorsal view 1.0 to 1.1 times the length of the mesoscutum. Scutellar foveae smooth ( Fig. 1F ) the lateral carinae of fovea are not straight in the posterior part. Lateral pit of scutellar fovea big, 1.5 to 2.0 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 2.87 to 3.50 times the width of the pit. Scutellar spine broad at base narrowing gradually towards apex ( Fig. 1F ). Scutellar disc in lateral view slightly slopping to base of scutellar spine, which is horizontally directed at base and very slightly curved downwards towards apex ( Fig. 3F ). Mesopleural impression straight and wide (strongly wider on the basal part) and without transverse carinae. Parapsidalsigna strongly marked and continuous, sometimes meeting on the anterior part. Mesolpeural triangle with dense pubescence anteriorly and sparse pubescence posteriorly. Propodeum with coarse, areolate sculpture, lateral and median propodeal carinae absent.

Wings – Marginal cell closed, 3.22 to 3.40 times longer than wide. Marginal pubescence of the wing starting from vein R1.

Metasoma – Petiole 2.0 to 2.2 times as long as wide, dorsally smooth, laterally smooth, dorsolaterally near the anterior end costate, ventrally longitudinally costate. Third abdominal tergum dorsally 1.00 to 1.08 the length of the fourth tergum.
