Pristomyrmex eduardi

Nothing is known about the biology of .

Identification
Wang (2003) - Worker. Masticatory margin of mandible with five teeth; pronotum unarmed; eyes with three to four ommatidia in the largest row. Its two close relatives are Pristomyrmex quindentatus, from Indonesia, and Pristomyrmex occultus, from Indonesia and Malaysia. Pristomyrmex eduardi can be separated from P. quindentatus and P. occultus because it lacks pronotal armaments and possesses smaller eyes (EL = 0.07, with three to four ommatidia in the longest row) in the workers.

Mandibles smooth and shining, except for a few longitudinal rugae. Masticatory margin of mandible with five teeth arranged as the strongest apical + the second strongest preapical + a diastema + three small denticles of similar size; the length of diastema is about equal to the distance covered by three small denticles. Basal margin of mandible lacking a toothlike prominence. Clypeus depressed, with a short median carina that does not reach the anterior clypeal margin but runs through the frontal area. Anterior clypeal margin with five toothlike prominences; the median three somewhat truncated. Ventral center of clypeus with a prominent tooth. Frontal carinae strong, extending to the level of the posterior margins of eyes and forming the dorsal margins of the shallow scrobes. Frontal lobes weak. Eye small, with three to four ommatidia in the longest row. Occipital margin in full-face view feebly concave. Pronotum unarmed, lacking a pair of teeth or spines. Propodeum armed with a pair of acute short spines. Metapleural lobes prominent and rounded. Petiole in profile view with a fairly long anterior peduncle; the anterodorsal angle of the node high, and its dorsum sloping downward posteriorly. Postpetiole in profile with a rounded dorsum. Dorsum of head with coarse rugoreticulum, except for a smooth, median longitudinal strip. Dorsum of alitrunk, as well as two sides of pronotum, with developed rugoreticulum. Petiole and postpetiole smooth and shining. Gaster unsculptured. Dorsal surfaces of head and alitrunk with numerous erect or suberect short hairs. Two pairs of the similar hairs present on the dorsum of petiolar node and three pairs on the dorsum of postpetiole. First gastral tergite lacking erect or suberect hairs. A few pairs of forward-projecting hairs present near the anterior clypeal margin. Scapes and tibiae with some erect to suberect short hairs. Color reddish-brown.
