Acanthaegilips alienus Ros-Farré & Pujade-Villar sp. n.
( Figs. 2D, 2E View FIGURE 2 , 4D View FIGURE 4 )
Studied material – 1; unknown. Holotype: 1 ( MZLU-MS) 22-VII-1990 at Prov. Pedernales, Sra. Bahoruco (1350 m), República Dominicana, L. Masner col.
Etymology – This name was chosen because this species is very different from all other Acanthaegilips species.
Colour – Head, mesosoma and petiole black, metasoma dark reddish brown. Scape yellowish brown, pedicel and flagellomeres brown. Legs yellowish brown except the apical part of hind tibia and metatarsus, which are brown. Mandibles light brown with dark brown teeth. Veins of wings medium brown.
Head – Without pubescence. Malar furrow in upper part very curved. Postocular furrow present. Occipital carina strong ( Fig. 4D View FIGURE 4 ). Malar space 0.62 times the height of the compound eye. Transfacial line 0.54 times the greatest width of head and 1.31 times the height of a compound eye. Pleurostomal lines weak. Antennal foramina separated from each other by 1.43 times the distance between the foramen and the compound eye.
Antennae – F1 to F4 cylindrical with a very small expansion at the apex, following flagellomeres cylindri- cal. Length of F1 1.2 the length of F2. Antennae without pubescence. Antennal formula: 10 (4.5): 3 (3.8): 11.5 (2.9): 9.5 (3.0): 10 (3.0): 10 (3.0): 10 (3.0): 10 (3.0): 10 (3.0): 10 (3.0): 10 (3.0): 9 (3.0): 9 (3.0): 12.5 (3.0). Placodeal sensilla start on F1. There are no modified flagellomeres.
Mesosoma – Anterior pronotal plate without pubescence. In dorsal part transversely carinulate changing to granulate laterally in level with the submedian depressions. Lateral pronotal carinae projecting dorsomedially to form a small tooth ( Fig. 4D View FIGURE 4 ). Lateral surface of pronotum with scattered hairs and with coarse areolate sculpture. Mesoscutum in lateral view 1.55 times higher than long; in dorsal view 1.37 times wider than long. Median mesoscutal impression weak, slightly longer than broad, notauli strongly and clearly impressed reaching 2/3 the length of mesoscutum, they are crossed by transverse carinae, they are not made up of a sequence of cells of the areolate sculpture ( Fig. 2D View FIGURE 2 ). Line of hairs on the anterior and lateral margins of the scutum absent. Scutellum in dorsal view with the same length as the mesoscutum. Dorsal, posterolateral and posterior surfaces of scutellum smooth. Scutellum concave roof-shaped, median scutellar carina almost obsolete, only visible as a carina near the anterior margin. Lateral pit of scutellar fovea elongated and narrow, 2.7 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 7.7 times the width of the pit. Scutellar disc in lateral view slopping to base of scutellar spine. End of scutellar disc narrowing abruptly to base of scutellar spine, which is slender, all the way ( Fig. 2D View FIGURE 2 ) and straight ( Fig. 4D View FIGURE 4 ). Mesopleural impression wide, straight and with transverse carinae. Mesopleural triangle with scattered hairs ( Fig. 4D View FIGURE 4 ). Propodeum smooth between lateral and median propodeal carinae ( Fig. 2E View FIGURE 2 ) and areolate in lateral areas.
Wings – Marginal cell open 2.73 times longer than wide. R1 absent. Marginal pubescence of the wing starting from the apical 3/4 of marginal cell but it is very sparse to the end of the cell.
Metasoma – Petiole 1.8 times as long as wide. Petiole with two dorsolateral furrows and ventrally with one longitudinal carina; weakly carinate laterally near anterior and posterior margins. Third abdominal tergum dorsally 0.81 the length of the fourth tergum.
