Male. Description. 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 ( Fig 52 View FIGURES 47 – 55 ), 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 0.5 × diameter of lateral ocellus. Palpal formula 2,3 (two maxillary and three labial). Notaulus absent on mesoscutum ( Fig 43 View FIGURES 38 – 46 ). Parapsidal line clearly impressed. Anterior margin of petiole longer than dorsal margin in lateral view ( Fig 34 View FIGURES 29 – 37 ). 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 as in Figure 60 View FIGURES 56 – 63 : 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 ( Fig 26 View FIGURES 23 – 26 ). Ventral margin of eye not edged with darker pigment or punctures. Body bicolored, head brown and remainder yellow ( Fig 34 View FIGURES 29 – 37 ).

Etymology. 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.

Distribution. MADAGASCAR: as in Figure 69 View FIGURES 64 – 72 .

Additional material examined: in addition to the type material, specimens from the following localities were examined in this study: MADAGASCAR. Parc National Andohahela, Col de Tanatana, 33.3 km NW Tolagnaro, 24 ° 45.51´S, 46 ° 51.22´E, 275 m alt., rainforest.

Remarks. Adetomyrma cilium is only known from males. The male of A. cilium is distinguished easily from the other Adetomyrma males by a combination of long hairs on the eye ( Fig 27 View FIGURES 27 – 28 ), long suberect hairs on the anterior surface of the mesofemur ( Fig 26 View FIGURES 23 – 26 ), and a well-developed subpetiolar process.

Adetomyrma cilium is relatively similar to A. clarivida . In this study, we regard these two as different species because of consistent differences in the mesofemur hairs ( Fig 26 View FIGURES 23 – 26 vs. Fig 25 View FIGURES 23 – 26 ) and development of the subpetiolar process. Additionally, these species differ in the shape of the aedeagus and the palpal formula.

This new species corresponds to the following species code used in previous studies:
