Scale bars 0.25 mm (161-162, 166), 0.2 mm (165, 167-168), 0.1 mm (163-164).    Paratypes: ISEA, 001.4188; 11 males, 3 females; collected together with the holotype. –  ZMMU; 2 males, 2 females; same data. –  MMUE; 3 males, 3 females; same data. –  MHNG; 2 males, 2 females; same data.   Etymology:The species is dedicated to our friend and colleague, Dr Alexei A. Zyuzin ( Almaty, Kazakhstan), an expert on the Lycosidae, who collected the typespecimens of this species.   Diagnosis:The male of  K. zyuzini sp. nov.can be readily distinguished from males of all other known  Karakumosaspeciesby the shape of the large, poorly marked proximal extension of the MA ( Figs 174, 176). The female of  K. zyuzini sp. nov.is most similar to that of  K. repetek sp. nov.from which it differs in the shape of the posterior transverse epigynal plate (with straight posterior margin vs.dumbbell-shaped, Fig. 179cf. Fig. 96) and the straight vs.C-curved spermathecae ( Fig. 182cf. Fig. 95).
