Worker
Zettel and Zimmerman (2007) - Lectotype (minor): TL = 3.6 mm; HW = 0.91 mm; HL = 0.91 mm; CI = 100; EL = 0.25 mm; OMD = 0.36 mm; SL = 0.92 mm; SI = 101; PW = 0.61 mm; HFL = 0.92 mm; HFI = 101. Paralectotype (minor worker; n = 1): TL = 3.6 mm; HW = 0.85 mm; HL = 0.88 mm; CI = 97; EL = 0.25 mm; OMD = 0.37 mm; SL = 0.87 mm; SI = 102; PW = 0.61 mm; HFL = 0.89 mm; HFI = 105.

Colour of minor: Blackish brown. Mandibles yellowish. Flagellum orange (first segment infuscated). Legs middle brown, tibiae slightly darker than femora, tarsi black. Whitish margins on tergites narrow, indistinct. Colour of gyne: Similar to worker. Clypeus and mandibles reddish. Hind margin of pronotum yellowish translucent. Tegulae and basal wing sclerites whitish yellow. Legs brown to reddish, only extreme base of tarsi black. Hind margins of tergites broadly whitish translucent.

Structural characteristics of minor worker: Generally more shiny than both Philippine species. Vertex almost smooth, with strongly reduced microsculpture. Clypeus with distinctly convex middle lobe, its apex inconspicuously surpassing level of sides. Sides of mesosoma, pro- and mesonotum matt. Metathoracic spiracular tubercles distinctly surpassing dorsal face of propodeum. Dorsal face of propodeum with strongly reduced reticulation, shiny, in lectotype with almost smooth medial groove (absent in paralectotype); posterior face with reduced reticulation, almost smooth dorsally. Tarsi moderately widened, similar to those of Forelophilus stefanschoedli. Dorsum of petiolar node smooth and shiny. Gaster almost smooth, with strongly reduced reticulation.

Queen
Zettel and Zimmerman (2007) - Paralectotype (gyne; n = 1): TL = 6.9 mm; HW = 1.38 mm; HL = 1.38 mm; CI = 100; EL = 0.44 mm; OMD = 0.51 mm; SL = 1.04 mm; SI = 75; PW = 1.17 mm; HFL = 1.24 mm; HFI = 90.

Structural characteristics of gyne: Similar to structural characteristics of worker. Dorsal surface almost completely matt (except narrow midline of mesosoma anteriorly) by dense, fine punctures or shagreen. Head sub-truncate, vertex straight in frontal view. Eye relatively large, distinctly surpassing outline of head. Three ocelli small. Clypeus with medial lobe distinctly surpassing sides, anteriorly shallowly notched, slightly impressed along midline in distal third, without ridge or tubercle. Mandible with a very small sixth tooth at base of masticatory margin. Pronotum with three setae on both sides of hind margin. In lateral view, outline of mesoscutum and mesoscutellum almost straight. Mesoscutum longer than wide (1.15 times). Mesoscutellum shorter than wide (0.9 times). Metanotal furrow deep. Propodeum with simple, convex outline in lateral view, with some setae on declivitous part. Tibiae without erect setae. Node of petiole, if seen from front or rear, distinctly widened towards dorsal margin. Gaster matt, but slightly shiny on white hind margins which occupy about one fifth of tergites 1 - 3 (narrower on tergite 4).
