Description

Operaria: Clypeus convexus, inter antennarum insertiones productus, margine antico recto, denticulis paucis, minutis instructo, ab area frontali limite obsoleto separatus. Mandibulae trigonae, latae, minute denticulatae. Antennae ori proxime insertae, 12 - articulatae, clava 3 - articulata, parum incrassata. Laminae frontales distantes, humiles, ultra oculos prolongatae, sulcum antennalem limitantes. Thorax superne sine suluris, pronoto metanotoque longe bispinosis. Petioli segmentum 1. postice cum nodo bispinoso seu bidentato; 2. globosum. Calcaria posteriora Simplicia. Miles: Caput permagnum, pagina inferiore cum thorace articulatum. Clypeus antice medio sinuatus, caeterum ut in operaria. Mandibulae superne convexae, inferius excavatae, margine masticatorio duplice, scilicet superiore recto, cultrato, inferiore dente valido armata. Laminae frontales magis prominentes; sulcus antennalis totum scapum accipiens, inde angulatum flexus et usque ad oculum descendens pro receptione baseos flagelli. Antennae breviores quam in operaria. Thorax superne sine suturis, pronoto inermi, melanoto spinis - longis erectis. Pedunculus ut in operaria, nodi 1. dentibus brevioribus.

Discussion

J'etablis ce genre remarquable sur trois especes, dont une seule a ete decrite par F. Smith, sous le nom de Pheidole notabilisHNS; elle provient de l'ile de Batjan. Les deux autres sont inedites. - A premiere vue, il semble se rapprocher de PheidoleHNS, dont il est bien distinct par la structure du thorax et le mode d'insertion de la tete sur le corselet, chez le soldat. L'insertion des antennes, tres rapprochee de la bouche, reduit l'epistome a ne former a cet endroit qu'un simple lisere a bord posterieur tranchant, entourant la fossette antennaire, comme chez PristomyrmexHNS. Le thorax sans suture ni impression, ainsi que le systeme' de sculpture, constitue par de grosses fossettes piligeres, rappelle egalement les PristomyrmexHNS. C'est avec ces derniers que le nouveau genre me parait offrir les affinites les plus importantes. ' F. Smith attribue a son P. notabilisHNS des mandibules sans dents, chez l'ouvriere, comme chez le soldat. Il n'a probablement pas su voir les petites dents espacees que je trouve aux mandibules de l'ouvriere, chez mes deux especes nouvelles.
