Agassiz).  Diagnosis. The species is recognizable externally by the white or light grey forewing with a black dash at base of costa, two black dashes at base of fold and three distinct black spots in cell. The male genitalia differ from the rest of  Aphanostolaspecies in the very short uncus in combination with apically narrowed saccus, the long, strongly curved gnathos, the basal projection of the phallus broadened at apex and the presence of small cornuti in the vesica. The female genitalia can be recognized unmistakably by the shape of the antrum and by the broad ductus bursae bearing a lateral appendix.  Description. Adult (Figs 1-3). Wingspan 7.2-8.4 mm. Head, thorax and tegulae light grey to white; labial palpus up-curved, segment two black with white apex, segment three white with broad black ring in middle; antenna in male thicker than in female, scape brown with some white scales beneath, other segments brown with white rings. Forewing white to light grey, costal margin black from base to 1/3 length, single black scales sparsely scattered along costal and dorsal margins; two black dashes in fold, sometimes merging; two black spots at base of cell and one black spot in corner of cell; cilia white, black-tipped. Hindwing white to greyish white.   Figures 1-21.Adults of  Aphanostolaspp. (scale bar 1.0 mm) 1.  Aphanostola acaciaesp. n., Namibia, Brandberg (gen. slide 73/05); 2.  Aphanostola acaciaesp. n., Namibia, Mirabib (gen. slide 548/14); 3.  Aphanostola acaciaesp. n., Kenya, Logumgum (gen. slide 1362); 4.  Aphanostola pentastigma, HT, RSA, Pretoria; 5.  Aphanostola pentastigma, Kenya, L.

Uncus very short, posterior margin weakly emarginated, covered with strong setae; gnathos long, curved by nearly right angle in middle; tegumen broad, with deep and broad anterior emargination; valva weakly narrowed in middle, apical half distinctly inflated, teeth on inner margin indistinct; sacculus narrow, thorn-shaped; vinculum moderately broad with short projections on posterior margin, medial postero-medial incision narrow; saccus broad at base, narrow distally, apex abruptly cut or rounded, exceeding far beyond apex of pedunculus; phallus wide, apex with group of 3-8 very small cornuti and three lateral teeth, basal projection slightly shorter than length of phallus, its apex weakly widened.   Figures 22-39.Adults of  Aphanostolaspp. (scale bar 1.0 mm) 22.  Aphanostola joannouisp. n., HT, RSA, Hongonyi Lodge; 23.  Aphanostola joannouisp. n., RSA, Hongonyi Lodge (209/12); 24.  Aphanostola namibiensissp. n., HT, Namibia, Brandberg; 25.  Aphanostola namibiensissp. n., Namibia, Auas Mts.; 26.  Aphanostola brandbergensissp. n., Namibia, Brandberg (gen. slide 74/05); 27.  Aphanostola aarvikisp. n., HT, Tanzania, Morogoro Town; 28.  Aphanostola africanellasp. n., Namibia, Mt.

Uncus sometimes reduced to short, paired hump. Female genitalia (Fig. 65). Segment VIII weakly sclerotized, distinctly shorter than apophyses anteriores; antrum broad, rounded; left side with a few teeth; sub-ostial sclerite narrow, prolonged with outwardly curved apex; ductus bursae of moderate width in basal 1/3, then very wide with indistinct transition to prolonged corpus bursae, short lateral appendix at 1/3 length; signum absent.  Etymology. The specific epithet refers to the hostplant,  Acacia tortilis, of the new species.  Distribution. South Africa, Namibia, Zimbabwe, Kenya.  Biology. The larva feeds on  Acacia tortilis(Forssk.) Hayne ( Fabaceae) in Kenya ( Agassiz and Bidzilya 2016in press). Adults were collected from late August to early June.
