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

( Figs. 2G , 4F )

Studied material – 1, 1. Holotype: 1 ( DCBU) 31-VIII-98 346 p. m. São Carlos ( Brasil) Carlos Henrique col. Paratype: 1 ( MZUSP) same data of holotype .

Etymology – This name was chosen because of the coarse transverse carinae of the pronotal sides.

Length of head + mesosoma + metasoma in female: 2.33 mm; in male: 2.63 mm.

Colour – Female. Head and metasoma black. Thorax dorsally black, laterally reddish dark brown. Mandibles light yellowish brown with darker tooth. Scape and pedicel and ventral side of flagellomeres light brown, dorsal side of flagellomeres brown. Legs light brown with medium brown coxae. Male. Scape and pedicel light brown, flagellomeres changing to dark brown. Hind legs medium to dark brown.

Head – Female. Head without pubescence, except for lines of hairs running with malar and postocular furrows. Malar furrow very weak, only marked by a change in the integument curvature; postocular furrow weak. Occipital carina strong. Malar space 0.63 times the height of the compound eye. Transfacial line 0.53 times the greatest width of the head and 1.07 times the height of a compound eye. Pleurostomal lines well impressed. Antennal foramina separated from each other by 2.25 times the distance between the foramen and the compound eye. Male. Malar furrow only marked by a change on the integument curvature but not as weak as in the female. Malar space 0.55 times the height of the compound eye. Transfacial line 0.52 times the greatest width of the head and with the same length as the height of a compound eye. Antennal foramina separated from each other by 2.16 times the distance between the foramen and the compound eye.

Antennae – Female. Flagellomeres cylindrical (slightly narrower on basis and apex). Length of F1 1.25 the length of F2. Antenna without pubescence except for a few hairs on scape. Antennal formula: 10 (4): 3 (3): 10 (2.8): 8 (2.5): 7 (2.5): 7 (2.7): 6.5 (2.9): 6 (3): 5.7 (3): 5.5 (3): 5 (3): 5 (3): 10 (3). Placodeal sensilla start on F2 they are not scarce in this antennomere. Male. Flagellomeres cylindrical (slightly narrower on basis and apex). Length of F1 1.25 the length of F2. Antenna without pubescence except for a few hairs on scape. Antennal formula: 11 (4): 3.5 (3.5): 12.5 (3): 10 (3): 9 (3): 9.8 (3.5): 9 (3.5): 9 (3): 8.5 (3): 8 (3): 8 (3): 7.5 (3): 7.2 (3): 10.2 (3). Placodeal sensilla start on F1 and they are not scarce in any antennomere. F3 to F5 and first 1/3 of F6 slightly expanded dorsolaterally with a longitudinal ridge on the raised part.

Mesosoma – Female. Lateral pronotal carinae projecting dorsomedially to form a very much raised tooth ( Fig. 4F ).

Anterior pronotal plate with a few scattered hairs near dorsolateral margins and transversely carinate. Lateral surface of pronotum densely pubescent in ventral part with coarse transverse carinae, in dorsal part with areolate-rugose sculpture. Mesoscutum in lateral view 1.67 times higher than long; in dorsal view 1.25 times wider than long. Median mesoscutal impression short, longer than wide. Notauli complete ( Fig. 2G ). Line of hairs on the anterior and lateral margins of the scutum absent. Scutellum in dorsal view 1.05 times the length of the mesoscutum. Scutellar foveae in anterior part with an internal short longitudinal carina, dividing the ante- rior area of each fovea into two areas, scutellar foveae mostly smooth with rugose sculpture near its posterior margin. Lateral pit of scutellar fovea absent. Scutellar spine broad, narrowing abruptly before apex ( Fig. 2G ). Scutellar disc in lateral view steeply slopping to base of scutellar spine, which is upwards directed at base and curved downwards, the apex is ventrally directed. Mesopleural impression rather narrow strongly curved in the apical part and with a lot of transverse carinae ( Fig. 4F ). Mesopleural triangle with very sparse pubescence. Propodeum with areolate sculpture, lateral and median propodeal carinae present, these are flat and wide in upper part. Male. Mesoscutum in lateral view 1.55 times higher than long; in dorsal view 1.19 times wider than long. Scutellum in dorsal view with the same length as that of the mesoscutum. Scutellar foveae more sculptured posteriorly than in the female. Lateral pit of scutellar fovea obstructed. Scutellar spine very slightly curved. Mesopleural impression not as curved as in the female.

Wings – Female. Marginal cell open 2.88 times longer than wide. R1 practically absent. Marginal pubescence of the wing starting from the apical 1/2 of marginal cell but it is very sparse to the end of the cell. Male. Marginal cell 3.38 times longer than wide. Marginal pubescence starting from the basal 1/3.

Metasoma – Female. Petiole as long as wide. Petiole dorsally smooth, laterally and ventrally costate. Third abdominal tergum dorsally 0.5 times the length of the fourth tergum. Male. Petiole wider than long. Dorsally, laterally and ventrally costate.
