Type material. Female holotype, slide # AT 210715 View Materials , CUBA, Jardín Botánico de Cienfuegos, Pepito Tey , 22 0 07’20.50'' N, 80 0 19’31.00'' W, from litter, 21 July 2015, coll. A.V. Tolstikov; paratypes: 16 females, 9 males, 8 larvae, 6 protonymphs, 5 deutonymphs, 5 tritonymphs, same data.

Type deposition: The holotype and most of paratypes are deposited in the mite collection of the Tyumen State University Museum of Zoology , Tyumen, Russia ; three female and two male paratypes are deposited in the mite collection of the Zoological Institute of RAS, St. Petersburg, Russia .

Etymology. The name of the new species refers to its distribution in Cuba.

Differential diagnosis. The female of this new species is most similar to T. aegypticus ( Soliman, 1974) and T. kethleyi sp. nov. by sharing the presence of only two pairs of genital acetabulae. The female of this new species differs from both species in having 6–7 pairs of aggenital and 3 pairs of genital setae (vs. 3 pairs of aggenital and 2 pairs of genital in T. aegypticus and T. kethleyi sp. nov.), genu I with 6 setae (vs. 7 in T. cf. aegypticus and T. kethleyi sp. nov.), 2 setae on genu II (vs. 3 in T. aegypticus and T. kethleyi sp. nov.) and genu IV with 1 seta (vs. 2 in T. aegypticus and T. kethleyi sp. nov.).
