Adetomyrma aureocuprea is only known from males. A. aureocuprea is completely sympatric with Adetomyrma bressleri, Adetomyrma caputleae, Adetomyrma goblin, and Adetomyrma venatrix, and was collected within a 20 km radius of Adetomyrma cilium and within a 70 km radius of Adetomyrma caudapinniger. 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 Adetomyrma clarivida. (Yoshimura and Fisher 2012)
Identification
Yoshimura and Fisher (2012) - 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.

Description
Male
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. 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. Anterior margin of petiole longer than dorsal margin in lateral view. Subpetiolar process not developed, without 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: 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. 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.
Type Material
Holotype. Male: CASENT0227991, BLF07304: MADAGASCAR, Fianarantsoa, Parc National d'Isalo, 9.1 km 354° N Ranohira, 22° 28.9´ S, 45° 27.7´ E, 725 m alt., gallery forest, at light, 27–31.i.2003, Fisher, Griswold et al. leg. California Academy of Sciences
Paratypes. 4 males: CASENT0247003 [CASC], CASENT0247004 The Natural History Museum, CASENT0490920 Musee d'Histoire Naturelle Genève, CASENT0490924 Museum of Comparative Zoology, with same data as holotype.
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.
Determination Clarifications
This new species corresponds to the following species code used in previous studies: mgm05.
