Etymology. The name honors the Argentinean arachnologist Maria Elena Galiano, who contributed for a long time to the research of salticids and was the first researcher to revise the genus Tullgrenella .

Diagnosis. Males of Tullgrenella galianoae Marta , sp. nov. resemble those of T. serrana by the embolus of left palp originating at about 9 o’clock position, but can be distinguished from them by the perpendicular tegulum, in relation to the cymbium apex, and the slender conductor ( Fig. 40C ). Females resemble those of T. gertschi by the posterior copulatory opening facing the lateral border of the epigynum ( Figs 5D , 41C–D vs 7N), but can be distinguished from them by the ventral short copulatory ducts overlapping the spermathecae ( Figs 41C–D ).

Copulatory ducts arranged in one monoplane spiral ( Figs 41C–D ). The first turn large, C-shaped, and overlapped the spermathecae in ventral view, while the subsequent turn dorsal and anterior to spermathecae. Spermathecae circular, positioned in medial part of epigynum, with base of fertilization ducts placed on anterior/dorsal surface. Fertilization ducts extended anteriorly to the sides ( Figs 41C–D ).

Distribution. Brazil (Bahia, São Paulo and Minas Gerais) ( Figs 53A–B ).

Natural history. Occurs in the Chacoan subregion, but more to the Northeast of Brazil ( Figs 53A–B ). The variation in altitudinal occurrence of this species is 97–912 m a. s. l. ( Figs 53A–B ).
