Tullgrenella guayapae Galiano, 1970: 327 , figs 10–13 (Male holotype from Patquía, Guayapa, província La Rioja, Argentina, M.E. Galiano leg., deposited in MACN 6238 , not examined).

Diagnosis of female. The female of Tullgrenella guayapae resembles that of T. morenensis (Tullgren, 1905) (see Galiano 1970, fig. 57) and T. brescoviti by the copulatory ducts with two loops, an outer one, and an inner one ( Figs 14 , 30, 31 ), and by the presence of posteriorly-opening coupling pocket ( Fig. 13 ), but differs from T. morenensis by the longer copulatory ducts with the two loops more compressed and closer to each other ( Figs 14 , 31 ), and differs from T. brescoviti by the shape of copulatory ducts and the larger spermathecae closer to each other ( Fig. 14 ).

Female description. Total length: 6.91. Carapace: length 3.06, width 2.28, height 1.76. Sternum: length 1.22, width 0.85. Clypeus height 0.20. Ocular area (ALE–PLE) 1.11. Anterior eye row 1.59 wide, posterior 1.65 wide. Diameter AME 0.35, ALE 0.23, PME 0.08, PLE 0.16. Abdomen: length 3.90, width 2.06, height 2.39. Leg formula: 4321. Length of femur I: 1.45; II: 1.48; III: 1.45; IV: 2.00; patella + tibia 1.76; II: 1.61; III: 1.53; IV: 2.15; metatarsus + tarsus I: 1.06; II: 0.98; III: 1.4; IV: 2.34. Palp: femur 0.62, patella 0.31, tibia 0.28, tarsus 0.65. Carapace ( Fig. 19 ) brown with white seta on posterior area; ocular area darkened. Chelicerae red-brown, with two prolateral teeth, with setae between teeth and one retrolateral tooth. Labium dark brown. Endites dark brown with lighter apices. Sternum pale brown, oval. Legs brown ( Fig. 19 ), except metatarsi and tarsi pale brown. Femur I and II more robust than others. Abdomen oval ( Fig. 19 ), brown, dorsum with dark bands, venter pale brown. Spinnerets pale brown. Leg macroseta I: femur 3 dorsal (1-1-1), 2 prolateral; tibia 6 ventral (2-2-2), 1 prolateral; metatarsus 4 ventral (2- 2-); II: femur 3 dorsal (1-1-1), 2 prolateral, 1 retrolateral; tibia 4 ventral (1-1-2), 1 prolateral; metatarsus 4 ventral (2-2); III: femur 3 dorsal (1-1-1), 1 prolateral; patella 1 prolateral, 1 retrolateral; tibia 4 ventral (2-2), 3 prolateral (1-1-1), 3 retrolateral (1-1-1); metatarsus 6 dorsal (2-2-2), 5 ventral (2-3), 2 retrolateral; IV: femur 3 dorsal (1-1-1), 1 prolateral; patella 1 prolateral, 1 retrolateral; tibia 3 prolateral, 3 retrolateral, 3 ventral (1-2); metatarsus 2 dorsal (1-1), 3 retrolateral (1-1-1), 3 prolateral (1-1-1), 4 ventral (2-2). Spermathecae developed and closer to each other ( Fig. 14 ). Copulatory openings are posteromedial ( Fig. 13 ). The posteriorly-opening coupling pocket present ( Figs. 13, 14 ). The copulatory ducts with two loops are closer to each other ( Figs 13, 14 , 30, 31 ). The fertilization ducts are posteriorly and membranous ( Figs 14 , 31 ).

Male description. See Galiano (1970: 327).
