Male. Description. Measurements: holotype. HL 0.57, HW 0.87, SL 0.16, EL 0.43, WL 1.42, MnW 0.9, CI 152.4, SI 18, EI 74.8, MnI 103.9.

HL 0.44–0.63, HW 0.59–0.91, SL 0.11–0.17, EL 0.3–0.45, WL 1.03–1.54, MnW 0.63–0.88, CI 135.6–145.7, SI 17.9–19.6, EI 67.4–75, MnI 97.1–106.3 (5 specimens measured).

Eye large and prominent, varied in size, but posterior margin not exceeding posterior margin of mid ocellus in full-face view ( Fig 47 View FIGURES 47 – 55 ). Distance between lateral ocellus and eye about same as diameter of lateral ocellus. Palpal formula 3,3 (three maxillary and three labial). Notaulus absent on mesoscutum. Parapsidal line usually unclear, sometimes weakly impressed but never pigmented with darker color ( Fig 38 View FIGURES 38 – 46 ). Anterior margin of petiole longer than dorsal margin in lateral view ( Fig 29 View FIGURES 29 – 37 ). Subpetiolar process not developed, without hairs ( Fig 29 View FIGURES 29 – 37 ).

Left and right parameres not overlapping or narrowly overlapping on dorsal small part of basimere ( Fig 20 View FIGURES 19 – 20 ). 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 56 View FIGURES 56 – 63 : distal portion narrowed distal to ventral projection, apical margin relatively sharp, but without small projection on its posteroventral portion, posteroventral margin of ventral projection convex.

Hair on compound eyes short, about 0.25× diameter of mid ocellus ( Fig 28 View FIGURES 27 – 28 ). With mesofemur in dorsal view, anterior face with dense appressed hairs, and sometimes several longer subdecumbent hairs on basal portion. Ventral margin of eye not edged with darker pigment or punctures. Body bicolored, head brown and remainder yellow ( Fig 29 View FIGURES 29 – 37 ).

Etymology. This species name is derived from the Latin words aureus (golden) and cupreus (coppery), referring to the body coloration. The species epithet is treated as a noun in apposition, and thus invariant.

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

Remarks. Adetomyrma aureocuprea is only known from males. A. aureocuprea is easily separable from the other Adetomyrma males by the yellowish body color, no mesoscutal notaulus, poorly developed subpetiolar process, lack of posterodorsal projection or lobe on the paramere, short hairs on the compound eye, and vestigial parapsidal line.

The males of Adetomyrma aureocuprea display remarkable morphological variation in, for example, the size of the eye and ocelli, head shape, mesonotal shape, petiolar shape, and hairs on body surface. A. aureocuprea ( Fig 64 View FIGURES 64 – 72 ) is completely sympatric with A. bressleri ( Fig 65 View FIGURES 64 – 72 ), A. caputleae ( Fig 66 View FIGURES 64 – 72 ), A. goblin ( Fig 71 View FIGURES 64 – 72 ), and A. venatrix ( Fig 72 View FIGURES 64 – 72 ), and was collected within a 20 km radius of A. cilium ( Fig 69 View FIGURES 64 – 72 ) and within a 70 km radius of A. caudapinniger ( Fig 68 View FIGURES 64 – 72 ). The morphological differences between all species are clear and consistent in each case of sympatric and geographically close localities, even though apparent similarity may be shown to a character of another Adetomyrma species collected from distant localities. In addition to the above species, the distribution of A. aureocuprea is parapatric with A. clarivida ( Fig 70 View FIGURES 64 – 72 ). Separation between A. aureocuprea and A. clarivida is strongly supported by the morphological differences observed in the aedeagus ( Figs 56 and 61 View FIGURES 56 – 63 ).

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