Abstrakt: A hitherto unknown TI-sulfosalt, containing antimony and arsenic, was discovered by ore microscopy (including quantitative reflectance measurements) and electron microprobe analysis in samples from the Allchar TI-Sb-As sulfide ore deposit (Macedonia). The chemical formula is TI5Sb9(As,Sb)4S22, X-ray single crystal and powder diffration data gave the lattice parametersαo = 7.393(4) Å, b0 = 8.707(2) Å, co = 17.584(3) Å,α = 103.81(1)°,β = 91.79(1)°,γ = 109.50(1)°; space group  $$P\bar 1$$ , Z = 1. The new mineral and the new mineral naine “jankoviéite” have been approved by the IMA/CNMMN.
