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

( Figs. 2F , 4E )

Studied material – 1; unknown. Holotype: 15 ( USNM) XII-1967 at Kingston, Jamaica, NLH Krauss col.

Etymology – This name was chosen due to the small length of this species.

Length of head + mesosoma + metasoma: 2.29 mm.

Colour – Head black, metasoma medium to light reddish brown with exception of propodeum and apex of scutellar spine, which are dark brown. Metasoma blackish brown. Antennae light brown. Mandibles reddish brown with darker tooth. Legs brown with exception of the tibia and tarsus of the first and medium legs, which are light brown. Veins of wings medium brown.

Head – Covered with very short and scattered hairs. Malar furrow very curved and not much strongly impressed. Postocular furrow present and not much strongly impressed ( Fig. 4E ). There are some scattered hairs in the postocular furrow and in the upper part of malar furrow. Pleurostomal lines weak. Occipital carina absent. Malar space 0.47 times the height of the compound eye. Transfacial line 0.5 times the greatest width of the head and 1.0 times the height of a compound eye. Antennal foramina separated from each other by 2.61 times the distance between the foramen and the compound eye.

Antennae – All flagellomeres cylindrical not expanded in width towards apex. Length of F1 1.2 times the length of F2. Antennae without pubescence. Antennal formula 9 (4.2): 3 (3.5): 11 (3): 9 (3): 9 (3): 9 (3): 9 (3.1): 8.8 (3.1): 8.5 (3.1): 8 (3.2): 8 (3.2): 8 (3): 7.5 (3): 10 (3). Placodeal sensilla start on F1 and they are not scarce on this antennomere. F3 to F5 weakly expanded dorsolaterally with a longitudinal ridge on the raised part.

Mesosoma – Lateral pronotal carinae projected dorsomedially to form a small and few raised tooth ( Fig. 4E ). Pronotal plate with few scattered short hairs, and with coriaceous sculpture. Lateral surface of pronotum with quite dense pubescence, weak areolatereticulate sculptured in the apical part and with irregular transverse carinae in the ventral part. Mesoscutum in lateral view 1.48 times higher than long; in dorsal view 1.22 times wider than long. Median mesoscutal impression very short and little longer than broad, notauli complete ( Fig. 2F ). Line of hairs on the anterior and lateral margins of the mesoscutum absent. Carinae between areolate sculpture wider and shinier than all other species of the group. Scutellum in dorsal view 0.91 times the length of the mesoscutum. Scutellar foveae smooth in the most part and with rugose sculpture in their posterior part ( Fig. 2F ). Lateral pit of fovea obstructed, superficial 1.6 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 3.8 times the width of the pit. Scutellar spine broad narrowing abruptly before apex. Scutellar disc in lateral view steeply slopping to base of scutellar spine, which is directed upwards at base and curved downwards, so that the apex is ventrally directed. Mesopleural impression narrow curved in upper part and with abundant weak transverse carinae. Mesopleural triangle glabrous. Propodeum with areolate sculpture. Median and lateral propodeal carinae present. The lateral carinae are wide and flat in upper part.

Wings – Marginal cell open 2.75 times longer than wide. R1 absent. Marginal pubescence of the wing starting from the apical 2/3 of marginal cell but it is very sparse to the end of the cell.

Metasoma – Petiole 1.8 times as long as wide, dorsally smooth, laterally and ventrally costate. Third abdominal tergum dorsally 0.6 times the length of the fourth tergum.
