Mey 10 ♂, 1 ♀, Otjozondjuba, Kombat, Farm Omatjete, 27. viii. 2012, leg. W. Mey (genitalia slide Mey 42 / 24) Remarks: Material of this recently described species had been deposited many years ago in several museum collections. The species was identified as a member of Metarbelodes Strand, 1909 due to four spurs on hind tibia, presence of a cossoid gnathos in the male genitalia (Fig. 3) and similar wing venation (Fig. 4). Morphological differences between Lukeniana and Metarbelodes are minimal. The geographic positions of the new localities are marked in Fig. 17. The habitats, where adults have been collected at the lights, are at the foothills of the Waterberg Plateau Park (Fig. 5) and south of the Otavi Mts.

W. Mey, (MfN, Berlin) Paratypes: 8 ♂, same data as Holotype (MfN, Berlin, NMNW, Windhoek) Etymology. The new species is named in honour of my brother Dieter Mey (Bad Tabarz, Germany), who was a reliable companion during our joint excursion to southern Africa. Description. Adult male (Figs 10, 11, 12): length of forewing 11 – 11.3 mm, wingspan 21 – 26 mm. Head and thorax with dense, grey-brown vestiture, labial palpi short, porrect, darker as the protruding hairs of frons; antenna brown, about half the length of forewing, bipectinate, sparsely scaled dorsally, rami with rows of setae on ventral side, 45 pairs of rami present. Proboscis and maxillary palpi absent. Legs grey-brown, with dense vestiture on dorsal side; epiphysis absent; hind tibia with apical spur pair. Wing venation in Fig. 13; forewings brown-beige, with characteristic position of short white streak along anal side of Cu 1 b, sometimes filled with 2 - 3 indistinct spots; transverse lines thin and pale, or absent; wing margin without line separating fringes, hindwings pale beige, sometimes darker apically, underside of wings pale beige, Male genitalia (Fig. 14): Segment IX fused to a ring-like structure, lateral sides constricted, basal and dorsal parts enlarged. Uncus a roof-like plate with shallow, semicircular emarginations on apical margin. Ventral side of anal tube with long, sinus-like subscaphium. Gnathos absent. Saccus short and broad, slightly curved dorsad. Valva nearly rectangular, apical margin convex, dorsal part membranous without sclerotized costa, ventral part sclerotized, both valvae fused basally along a band-like structure. Inner apodeme of base of valva large, curved, outer apodeme short. Juxta elongate, attached to diaphragma on basal part around phallus. Phallic apparatus tubular, ventral apex acute, vesica without cornuti. differences are observable in wing venation: areole elongate in forewing of M. naumanni and R 3 + 4 + 5 with a short stalk, and in hindwing Sc + R 1 present as short fork at wing margin. In M. dietermeyi sp. nov. the areole is short and R 3 + 4 and R 5 originate separately from areole, and in the hindwing Sc + R 1 fused to wing margin. In male genitalia, the new species has a very long and curved inner apodeme of valva, and the emargination of the apical margin of the valva are much shallower. Based on wing pattern and genitalia both species form a species-pair, whose most closely related species seems to be M. cymaphora Hampson, 1910, described from eastern Africa. The new species seems to be an endemic of the western parts of the Great Escarpment in Namibia.

The diagnostic and readily observable difference between the two species is the brown ground colour of forewings of M. naumanni (Fig. 7) which contrasts with the beige wings of M. dietermeyi sp. nov.
