Yoshimura and Fisher (2012) - The male of A. cilium is distinguished easily from the other Adetomyrma males by a combination of long hairs on the eye, long suberect hairs on the anterior surface of the mesofemur, and a well-developed subpetiolar process.
Adetomyrma cilium is relatively similar to Adetomyrma clarivida. We regard these two as different species because of consistent differences in the mesofemur hairs and development of the subpetiolar process. Additionally, these species differ in the shape of the aedeagus and the palpal formula.

Measurements: holotype. HL 0.65, HW 0.88, SL 0.2, EL 0.46, WL 1.62, MnW 0.98, CI 134, SI 22.9, EI 71.1, MnI 112.2.
HL 0.61–0.65, HW 0.86–0.96, SL 0.19–0.21, EL 0.44–0.5, WL 1.48–1.71, MnW 0.88–1.08, CI 136.7–147.6, SI 21.3–22.5, EI 72.5–76.7, MnI 102.2–117.8 (3 paratypes and 1 individual measured).
Eye well developed and prominent, its posterior margin not exceeding posterior margin of mid ocellus in full-face view. Distance between lateral ocellus and eye varies from equal to or shorter than diameter of lateral ocellus, but always longer than 0.5X diameter of lateral ocellus. Palpal formula 2,3 (two maxillary and three labial). Notaulus absent on mesoscutum. Parapsidal line clearly impressed. Anterior margin of petiole longer than dorsal margin in lateral view. Subpetiolar process developed, but presence of hairs on process variable.
Left and right parameres not overlapping or narrowly overlapping on dorsal small part of basimere. No distinct projection or lobe present on posterodorsal portion of paramere. Basal ring not reduced, covering whole anterior margin of paramere in lateral view. Basal projection on cuspis clear but not extraordinarily well developed. Aedeagus in lateral view slightly and gradually narrowed from ventral projection; apical margin relatively sharp, with a small, broadly triangular projection on posteroventral portion; posteroventral margin of ventral projection concave.
Hairs on compound eyes long, as long as or longer than diameter of mid ocellus. Mesofemur in dorsal view, anterior face with dense subdecumbent and many long suberect hairs. Ventral margin of eye not edged with darker pigment or punctures. Body bicolored, head brown and remainder yellow.

This species name is derived from the Latin word cilium (eyelash), and refers to the long hairs on its compound eye. The species epithet is treated as a noun in apposition, and thus invariant.
This new species corresponds to the following species code used in previous studies: mgm04: Yoshimura & Fisher 2012.
