Known only from the type material. Andretta, the type locality of this species is a fascinating green hill station (devoid of litter) surrounded on all sides by tea gardens and pine forests before they merge with the Dhauladhar range (a southern branch of the main Outer Himalayan chain of mountains). This species is uncommon in the Shivalik range of northwest Himalaya and was collected twice from the same locality while the ants were raiding on the soil surface.
Bharti et al. (2012) - Aenictus wilsoni can be easily separated from Aenictus pangantihoni and Aenictus rabori by its microrecticulate head capsule but is somewhat similar to Aenictus philippinensis from which it can be fairly separated by a combination of characters. Aenictus philippinensis has medium reddish brown color, smaller scapes (SI, 78.20), convex basal face of the propodeum and a strongly impressed metanotum, whereas Aenictus wilsoni has a blackish color, longer scapes (SI, 93.15–100), straight basal face of propodeum and indistinct metanotal impression. Presence of rugae, ridge immediately followed by three fossae; an oblique excavation present between the lower 1/3 of the meso and metapleuron are found in latter only.

TL, 4.02–4.32; HL, 0.79–0.84; HW, 0.7–0.74; SL, 0.68–0.71; WL, 1.30–1.38; PL1, 0.31–0.33; PL2, 0.34–0.41; GL, 1.25–1.37. Indices: CI, 85.06–90.12; SI, 93.15–100 (n=15).
Head. Head longer than broad; narrowed posteriorly, sides convex; seen in full face view its posterior margin convex; some specimens have occiput with well demarcated collar. Parafrontal ridge distinct, about 0.27 mm long. Antenna 10 segmented; scape reaching up to the posterior margin of head. Clypeus convex, extending slightly anterior of frontal lobes; mandible broad, triangular with large apical tooth, followed by eight irregular, ill defined denticles.
Mesosoma. Promesonotum gently convex in profile; propodeum lower than promesonotum, its dorsal outline straight. Mesonotum demarcated from the mesopleuron by a distinct ridge; which is immediately followed by three fossae placed horizontally; metanotal impression indistinct. An oblique excavation is present between the lower 1/3 of the meso and metapleuron. Propodeal junction forms an angle of about 90°.
Petiole, Postpetiole. Petiole rectangular in dorsal view, margined anteriorly by a transverse carina. Postpetiole gibbous, broadened posteriorly; subpetiolar process a low, almost non-existent inconspicuous convex lobe.
Gaster. Gaster oval, sting exerted.
Sculpture. Head, mesosoma, petiole and postpetiole entirely microreticulate and opaque. In addition, low ill defined longitudinal rugae cover mesonotum and propodeum; lower half of mesopleuron consists of broad, sturdy rugae as well. Mandibles striate with punctured apices.
Pilosity. Moderate; suberect, denser on antennae and legs; sparse on gaster.
Color. Blackish, with brown gena, gaster, and appendages.
Holotype worker. India, Himachal Pradesh, Andretta, 32.0744°N 76.5856°E, 940 m, 12.vi.2010, hand picking (coll. Aijaz A. Wachkoo). 14 paratype workers; same data as holotype.
The species epithet is given to honor E. O. Wilson.
