Tartamura adfectuosa (Galiano, 1977) comb. nov.

Arachnomura adfectuosa Galiano, 1977a: 145 (male holotype from Cordón Esmeralda [38.09°S, 91.83°W], Sierra de la Ventana, Provincia de Buenos Aires, Argentina, 3.X.1972, M.E. Galiano, deposited in MACN 6729 , not examined); World Spider Catalog 2017.

Diagnosis. Males resemble those of Ta. agatelin sp. nov. in having a long embolus, not reaching the dorsum of the cymbium (see Galiano 1977a: figs 16‒17). Females resemble those of Ta. huao sp. nov. in having a unilobed posterior edge on epigyne (see Galiano 1977a: figs 23‒24). Males differ from all the other species of the genus in having more than one row of distal spine-like setae on the anterior face of the chelicerae and in having a square RvTA ( Galiano 1977a: figs 14, 16). Females resemble those of Ta. huao sp. nov. by the abdominal dorsal pattern, but differ in where the copulatory ducts enter the spermathecae: posteriorly in Ta. huao sp. nov. ( Figs 21D‒21E ), anteriorly in Ta. adfectuosa ( Galiano 1977a: fig. 24).

Description. See Galiano (1977).

Distribution. Known only from Argentina (Galiano 1977, World Spider Catalog 2017).

Note. In the phylogeny proposed by Ruiz & Maddison (2015), Arachnomura aff. hieroglyphica ( A. querandi sp. nov. herein described) was found not closely related to Tartamura gen. nov. Tartamura adfectuosa comb. nov. has spine-like setae clustered on the distal end of the chelicera, as in the species of Tartamura herein described (scatered spine-like setae in Arachnomura , as in other genera but Titanattus ), which supports the transfer.
