Namasia Diakonoff, 1983 , 5: 259.

Type species: Namasia catoptrica Diakonoff, 1983

Diagnosis. In the hindwing the veins Rs and M1 are stalked, as are M3 and CuA1. Male hind tibia with brush of blackish brown scales. The wing pattern consists of a conspicuous speculum and costal strigulae of which only the two apical ones are distinct; ground colour dark brownish grey with indistinct, angled transverse lines. Male genitalia ( Figures 11, 12 ). Tegumen high, gnathos present as setose lobes; valva slender, simple; phallus basally broad, tapering, apically tubular.

Female genitalia ( Figure 14 ). Ovipositor semitelescopic; two setose lobes present posterior to ostium; ostium indistinct; ductus bursae without sclerotisations; ductus seminalis originates close to ostium; signa horn-shaped with broad bases.

Remarks. Diakonoff (1983) proposed the

genus Namasia for N. catoptrica described in the same work. The species and genus was based on a female from Asir Mts., Saudi Arabia. The authors’ material from Kenya and Tanzania agree both with Namasia catoptrica Diakonoff, 1983 from Arabia and with Eucosma monitrix Meyrick, 1909 from South Africa. Razowski & Krüger (2007) transferred E. monitrix to Eucosmocydia Diakonoff. We do not agree with this placement. The holotype female is the only specimen of the genus known from the Arabian peninsula. Although we see no difference between our females from East Africa and Diakonoff’s figures, we hesitate to synonymize the two names before males from both areas can be compared.
