Gymnosophistis thyrsodoxa Meyrick, 1934

( Figs 1–3 , 7 )

Lectotype: ♂ ( Fig. 3 ), Kenya, Mt. Elgon , S.E. slopes of, 18 miles S.W. of Kitale, 6000–7000 feet, December 1932, T. H. E. Jackson leg.; TYPE LEPI0080; with labels: “ Dec. 1932. / Mt.Elgon,S.E. / slopes of. 18 m. / S.W. of Kitale, / 6–7000 feet. / d.d. T.H.E. / Jackson.1933.” “Mt. Elgon / Dec 1932 / T. H. E. Jackson ”; “ ♂ genitalia on / slide 4.III 1949 / J.F.G.C. 9134”; “TYPE LEP.: No. 80 / Gymnosophistis 1/2 / thyrsodoxa / Meyrick / HOPE DEPT.OXFORD”; “Gymno- / sophistis / thyrsodoxa, / Gen. & sp.n. / Det Apr.1934. / Edw.Meyrick.”; “Genitalia / slide / 246-1953”; “Type”, designated herein.

Paralectotype: 1♂ ( Figs 1–2 ) with labels: “ Dec. 1932. / Mt.Elgon ,S.E. / slopes of. 18 m. / S.W. of Kitale, / 6– 7000 feet. / d.d. T.H.E. / Jackson.1933.”; “ Mt. Elgon / Dec 1932 / T. H. E. Jackson ”; “TYPE LEP.: No. 80 / Gymnosophistis 2/2 / thyrsodoxa / meyrick / HOPE DEPT.OXFORD”; “Gymno- / sophistis / thyrsodoxa, / Gen. & sp.n. / Det Apr.1934. / Edw.Meyrick.” ( OUMNH) .

The dissected specimen with the genitalia-slide-number “246-1953” and the red bordered, round label “Type” is here designated as the lectotype. Meyrick (1934) states “ Uganda ”, however, the Ugandan border is in a distance of more than 50 km from Kitale; thus, I consider the type locality most probably situated in Kenya. Both type specimens are in poor condition, with several body parts lacking. However, labial palpus, scaling, pattern and wings are well visible and a complete (left) antenna is preserved on the lectotype ( Fig. 3 ). The uncus is ruptured lengthwise, which is why its original shape is somewhat difficult to assess ( Fig. 7 ). It is best seen in the right half.
