Aenictus EugeniiHNS, n. sp.

- (Pl. 2, fig. 1 - 4). [[ worker ]]. Rufo-ferruginea, antennis, pedibus, pedunculi segmento 2 ° abdomineque flavo-testaceis, mandibularum margine nigricante, longissime pilosa, nitida, mesopleuris, metathorace toto pedunculique segmento 1 ° confertissime punctatis, opacis; capite vite longiore quam latiore, mandibulis angustis, striatis, apice oblique truncatis, acutissimis, antennarum flagelli articulis omnibus longioribus quam crassioribus, metanoti parte declivi verticali, lateribus marginata, sutura meso-metanotali impressa, pedunculi segmento 1 ° parum longiore quam latiore, compresso, subtus cum dente obtuso, 2 o superne subgloboso. - Long. 3 1 / 2 mill. - Makapan; un exemplaire.

Cette espece se fait remarquer par sa taille elancee et ses longues antennes. La tete est large et rappelle en petit celle d'un AnommaHNS. Les mandibules sont etroites, a bords paralleles, obliquement tronquees au bout; ce bord apical offre a sa partie posterieure 6 - 7 tres petites dents, suivies d'une enorme dent aigue qui en forme la pointe. Les antennes sont allongees, toutefois le scape est loin d'atteindre l'occiput et est a peine plus long que les 5 premiers articles du flagellum; les articles de celui-ci sont distinctement plus longs qu'epais. Les aretes frontales font saillie en avant sous forme de deux petites dents, depassant l'epistome. Le corselet est lisse en dessus jusqu'a la suture meso-metanotale; toutefois, le dos du mesonotum offre a un fort grossissement des traces de ponctuation.
