Description
Worker
Holotype. TL 2.3, HL 0.63, HW 0.42, CI 67, ML 0.28, MI 44, SL 0.36, SI 86, PW 0.26, AL 0.66. Characters of signeae-complex. Apicoscrobal hair simple; dorsolateral margin of head posterior to this with 2-3 similar but shorter simple projecting hairs. Cephalic dorsum with a transverse row of 4-6 erect hairs at occipital margin; without standing hairs anterior to this. Pronotal humeral hair simple, stiff and straight. Pronotal dorsum with a single pair of short erect hairs, mesonotum with a single pair of much longer erect simple hairs. Entire dorsal alitrunk finely and densely reticulate-punctulate. Katepisternum with a small smooth patch but side of alitrunk otherwise entirely reticulate-punctate. Lamella on propodeal declivity broad, concave immediately below tooth but lower down declivity forming a convex lobe. Petiole node in dorsal view as broad as long, reticulate-punctate. In profile lateral spongiform lobe of petiole extends anteriorly beyond midlength of node; height of anterior face of node less than length of dorsum. Disc of postpetiole with faint superficial punctulate sculpture and with vestiges of scattered longitudinal costulae. First gastral tergite with weakly remiform standing hairs. Basigastral costulae shorter than disc of postpetiole.
Paratype. TL 2.4, HL 0.64, HW 0.44, CI 69, ML 0.29, MI 45, SL 0.38, SI 86, PW 0.27, AL 0.70.
