Nothing is known about the biology of this ant.
LaPolla (2004) - Worker: 11 segmented antennae; mandible with 5 teeth and indistinct ridges that run along dorsal surface fading toward median portion of mandibles; scapes > 0.9 mm; many erect hairs on head, mesosoma and gaster giving ant a "spiky appearance." Queen: As in worker with modifications expected for caste. Male: As in Acropyga acutiventris, except hairier and penis valve differences. Compare with Acropyga acutiventris.
This species is the largest known Acropyga species, and is closely related to Acropyga acutiventris.

LaPolla (2004) - Acropyga rubescens has been elevated to species status based on 6 points of distinction from A. acutiventris: 1) setation of A. rubsecens is distinct: a) much denser hairs in general found across body; b) hairs on posterior margin of head often very long, much longer than seen in A. acutiventris; c) mesosomal hairs longer and denser; 2) A. rubescens larger overall; 3) with longer scapes (higher SI); 4) dorsal mandibular striate sculpture thinner disappearing about mid-way toward mandible articulation point with head; 5) shapes of penis valves differ; 6) both "forms" are sympatric in India/Sri Lanka region.
LaPolla (2004) - (n=7): TL: 3.39-5.11; HW: 0.891-1.16; HL: 0.915-1.06; SL: 0.914-1.16; ML: 1.07-1.31; GL: 1.35-2.74; CI: 91.53-109.43; SI: 97.39-106.67.
Head: brownish-yellow to reddish-yellow; head about as broad as long; posterior margin concave; covered in a thick layer of appressed hairs, with many scattered, long erect hairs especially along posterior margin; eyes relatively large, placed at lower 114 of head; 11 segmented, incrassate antennae; scape nearly reaches or surpasses posterior margin up to length of pedicel; clypeus broad, slightly convex medially with many erect hairs, the longest ones along anterior clypeal margin; mandible with 5 uneven teeth; 3rd and 5th tooth (from apical to basal) smaller than others; dorsal surface of mandible covered in many erect hairs and with indistinct ridges originating near base of teeth and fading entirely toward middle of mandible; slight gap present between inner mandibular surface and anterior clypeal margin. Mesosoma: brownish-yellow to reddish-yellow; mesosoma covered throughout in dense layer of appressed hairs with scattered erect hairs of varying lengths; pronotum in lateral view typically with short shelf before rising sharply toward mesonotum; mesonotum rounded with many long erect hairs (many times longer than shortest erect hairs); metanotal area distinct; propodeum rounded, below level of mesonotum, propodeal dorsum flat before steep declivity; propodeum with dense layer of erect and appressed hairs. Gaster: brownish-yellow to reddish-yellow, darker than head and mesosoma; petiole thick and erect reaching height of propodeum; yellow to light brownish-yellow; gaster covered in thick layer of appressed hairs with many scattered erect hairs throughout giving a "spiky" appearance.
LaPolla (2004) - (n= l): TL: 6.16; HW: 1.36; HL: 1.36; SL: 1.34; ML: 2.23; GL: 2.57; CI: 100; SI: 98.53. As in worker with modifications expected for caste.
LaPolla (2004) - (n= l ): TL: 3.52; HW: 0.644; HL: 0.665; SL: 0.611 ; ML: 1.25; GL: 1.6; CI: 96.84; SI: 94.88.
Head: brownish-yellow to reddish-yellow, darker around three prominent ocelli; head about as broad as long; covered in layer of appressed hairs with suberect to erect hairs; eyes large, breaking outline of head in full frontal view; 12 segmented, slightly incrassate antennae; scape surpasses posterior margin by about length of first two funicular segments; clypeus broad, relatively flat, with scattered short erect hairs; mandible with 4 teeth; a gap exists between inner mandibular margin and anterior clypeal margin. Mesosoma: light brownish-yellow to reddish-yellow; pronotum short and collar-like; mesonotum large, rounded anteriorly; mesonotum dorsum flat, with layer of shorter appressed hairs and scattered longer erect hairs throughout; propodeum lower than mesonotum and scutellum; declivity not distinct from propodeum. Gaster: petiole thick and erect; gaster brownish-yellow to reddish-yellow, darker dorsally; covered in dense layer of appressed hairs with scattered erect hairs throughout. Genitalia: in lateral view parameres thick, tapering to a rounded apex; parameres with medial dorsolateral extensions; cuspi short, bent toward approximately middle of digiti, where they meet with short, peg-like teeth at apex; digiti long and erect with short peg-like teeth where cuspi meet, apex rounded.
