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

( Figs. 2A , 4A )

Studied material – 1; unknown. Holotype: 1 ( UCR) 16-XI-1994 at Heredia, Est. Biol. La Selva. (100 m) ( Costa Rica). 10°26’N / 84°01’W Fot 38, P. Hanson col.

Etymology – This name was chosen because the tooth of the anterior pronotal plate, which is very much raised.

Length of head + mesosoma + metasoma: 2.55 mm.

Colour – Head and metasoma black. Mandibles yellow. Metasoma dark reddish brown. Mandibles light brown with medium brown teeth. Antennae light brown with exception of the four last flagellomeres, which are dark brown. Legs light brown with the exception of the metafemur and the metatibia, which are dark brown. Veins of wing light brown.

Head – Without pubescence. Malar furrow very curved, postocular furrow well impressed ( Fig. 4A ). Occipital carina strong. Clypeal zone not marked and pleurostomal lines very weak. Malar space 0.65 times the height of the compound eye. Transfacial line 0.58 times the greatest width of the head and 1.11 times the height of a compound eye. Antennal foramina separated from each other by 1.5 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 cylindrical. Length of F1 1.33 the length of F2. Scape with scattered short hairs, pedicel and flagellomeres glabrous. Antennal formula: 10 (3): 2 (2): 8 (2): 6 (2): 5.5 (2): 5.5 (2): 4.5 (2): 4 (2): 4 (2): 4 (2.5): 4 (3): 4 (3): 8 (3). Placodeal sensilla start on F3 but they are dorsally scarce and ventrally absent on this flagellomere, on F4 they are ventrally scarce.

Mesosoma – Lateral pronotal carinae projecting dorsomedially to form a very much raised tooth ( Fig. 4A ). Anterior pronotal plate with short scattered hairs on the margins and with a very conspicuous rugulose sculpture. Lateral surface of pronotum with dense pubescence and with areolate sculpture. Mesoscutum in lateral view 1.66 times higher than long; in dorsal view 1.17 times wider than long. Median mesoscutal impression short, longer than broad. Notauli complete ( Fig. 2A ). 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 smooth and with an internal longitudinal carina dividing them into two areas each. There is rugose sculpture at the area compressed between the end of scutellar foveae and before the apex. Lateral pit of scutellar fovea almost circular, 1.1 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 2.78 times the width of the pit. Scutellar spine broad narrows abruptly before apex ( Fig. 2A ). Scutellar disc in lateral view steeply slopping to base of scutellar spine, which is strongly directed upwards at base and curved downwards, so that the apex is ventrally directed. Mesopleural impression rather narrow curved in the apical part and with few coarse transverse carinae ( Fig. 4A ). Mesopleural triangle sparsely pubescent anteriorly and more sparsely pubescent posteriorly ( Fig. 4A ). Propodeum with areolate sculpture. Median and lateral propodeal carinae present.

Wings – Marginal cell open 2.6 times longer than wide. R1 short not reaching the margin of the wing. Marginal pubescence of the wing starting from the apical 1/3 of marginal cell but it is very sparse to the end of the cell.

Metasoma – Petiole 1.12 times as long as wide. Petiole dorsally, laterally and ventrally costate. Third abdominal tergum dorsally 0.63 the length of the fourth tergum.
