Nomenclature

 *  rabori. Aenictus (Aenictus) rabori Chapman, 1963: 249, fig. 2 (w.) PHILIPPINES. See also: Wilson, 1964a: 476; Jaitrong & Yamane, 2012: 74.

Worker
Wilson (1964) - Syntypes: Worker selected at random: HW 0.78 mm, HL 0.83 mm, SL 0.62 mm; HW of remainder of long syntype series 0.82-0.84 mm. Antenna 10-segmented. Mandibles typical. Clypeus convex, entire unarmed. Parafrontal ridge about 0.17 mm. Occiput very feebly convex, lacking distinct collar. Mesonotum demarcated from mesopleuron by a conspicuous ridge; a striking character shared within the genus only by the sympatric philippinensis. In addition, mesonotum drops to metanotum through a short vertical face; this character is peculiar to rabori. Unlike rabori, metanotum is level with basal face of propodeum. Femora and tibiae distinctly thicker than in philippinensis. Propodeal junction acutely angulate. Subpetiolar process almost non-existent, consisting at most of a very low central convexity. Pilosity moderately abundant; length of longest pronotal hairs 0.15 mm.

Entire head shining. Pronotal dorsum shining; remainder of mesosoma microreticulate and opaque. Pedicel microreticulate, its dorsum shining; remainder subopaque. Color as in philippinensis.
