Worker and queen unknown.
Male. Description. Measurements: holotype. HL 0.64, HW 0.7, SL 0.2, EL 0.52, WL 1.58, MnW 0.98, CI 109.8, SI 28.3, EI 82, MnI 140.3.
HL 0.6–0.68, HW 0.91–0.97, SL 0.18–0.2, EL 0.49–0.54, WL 1.45–1.63, MnW 0.87–0.99, CI 142.1–150.2, SI 18.6–21, EI 77.8–81.5, MnI 95.5–107.7 (3 paratypes and 2 individuals measured).
Eye extremely large and prominent (Fig 53): posterior margin exceeding posterior margin of mid ocellus in full-face view in most cases. Distance between lateral ocellus and eye shorter than 0.5× of diameter of lateral ocellus (Fig 23). Palpal formula 3,3 (three maxillary and three labial). Notaulus absent on mesoscutum (Fig 44). Parapsidal line usually clearly impressed, sometimes weak and unclear. Anterior margin of petiole longer than its dorsal margin in lateral view (Fig 35). Subpetiolar process developed as triangular process without ventral hairs.
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 61: narrowed after ventral projection; apical margin relatively blunt, with a small, broadly triangular projection on its posteroventral portion; posteroventral margin of ventral projection convex.
Hair on compound eyes short, 0.33× to 0.5× diameter of mid ocellus. Mesofemur in dorsal view, anterior face covered with dense subdecumbent hairs, but without longer hairs (Fig 25). Ventral margin of eye edged with darker pigment and minute punctures. Body bicolored, head brown and remainder yellow (Fig 35).
Etymology. This species name is derived from the Latin word clarividus (clairvoyant), referring to the large eye size of the new species. The species epithet is treated as a noun in apposition, and thus invariant.
Distribution. MADAGASCAR: as in Figure 70.
Additional material examined: in addition to the type material, specimens from the following locality was examined in this study: MADAGASCAR. Parc National Marojejy, 14° 26.29´S, 49° 46.44´E, 488 m alt., rainforest.
Remarks. Adetomyrma clarivida is only known from males. The male of A. clarivida is distinguished easily from the other Adetomyrma males by a combination of large eye size (Fig 53), the large ocellus, which is located close to the posterior eye margin (Fig 23), the mesofemur lacking long hairs on its anterior surface (Fig 25), less developed subpetiolar process, and the hairs on the compound eye, which are more than 0.33× of the horizontal diameter of the mid ocellus.
Adetomyrma clarivida is morphologically similar to A. cilium and A. aureocuprea. However, A. clarivida lacks long hairs on the mesofemur (Fig 25), while A. cilium has short and long hairs (Fig 26); A. clarivida has a 3,3 palpal formula, while A. cilium has a 2,3 formula; A. clarivida has longer hairs on the eye which are more than 0.33× of mid ocellus diameter, while A. aureocuprea has shorter hairs which are about 0.25× of mid ocellus diameter (Fig 28). The distance between the lateral ocellus and eye in A. clarivida (0.5× of lateral ocellus diameter) is shorter (Fig 23) than the distance in A. aureocuprea (the same as lateral ocellus diameter). Although A. aureocuprea shows great variation in the size of the eye and some specimens of A. aureocuprea are apparently similar to A. clarivida, a combination of the characters in the eye hairs and ocellus-eye distance consistently separates A. clarivida from A. aureocuprea.
This new species corresponds to the following species code used in previous studies:
