Etymology. The specific epithet is a patronym in honor of Dr. Joanna Gardziṅska, who has contributed much to the taxonomy of this genus.

Diagnosis. Differs from other described species ( Gardziṅska & Patoleta 1997; Gardziṅska 2009) and T. tualapa by the vulva located posterior to the window ( Figs 232–233). The absence of guanine deposits in the eye area can distinguish the species from T. creba , T. zabkai and T. squamosa ( Fig. 231). Differs from T. aliena by the absence of bright stripes on the abdomen ( Figs 230–231) and the epigynal shape ( Figs 232–233).

Description. Female (holotype, UBC-SEM AR00101). Carapace length 1.8 (variation 1.8–1.9, n=3); abdomen length 2.0. Chelicera: red brown; with two promarginal teeth and one retromarginal tooth of five cusps. Tibia of first leg with three pairs of ventral macrosetae; metatarsus with two pairs. Measurements of legs: I 3.5, II 3.4, III 4.4, IV 4.7. Epigynum ( Figs 232–233): window big; vulva posterior to window. Copulatory duct long and coiled, without accessory gland; spermatheca small. Color in alcohol ( Fig. 231): carapace dark brown with a yellow brown marking behind PLEs; abdomen dark brown, scattered with small brownish speckles, with a wide yellowish brown band at anterior end and in the middle each; venter of abdomen sandy yellow with gray patches; legs yellow brown with gray brown annuli.
