Description
(Figs 48–49, 130)
Cicurina machete Gertsch 1992: 114, figs 125–126 (description of female). — Jackman 1997: 162.
HOLOTYPE female: “ Texas; San Saba Co. Whiteface Cave, 20 mi. South of Richland Springs, February 9, 1964 J. Reddell; D. McKenzie & K. Garrett ”. Examined (AMNH).
Description. Female holotype
Total length: 4.68; carapace length: 2.43; carapace width: 1.53; opisthosoma length: 2.25. Eyes absent. Cheliceral promargin right side with 3 teeth (2 large, 1 small), left side likewise; retromargin right side with 5 denticles (3 large, 2 small), left side with 7 denticles (3 large, 4 small). Leg I: total length: 7.45; femur: 2.05; patella: 0.65; tibia: 1.85; metatarsus: 1.80; tarsus: 1.10; leg IV: total length: 8.98; femur: 2.35; patella: 0.75; tibia: 2.20; metatarsus: 2.48; tarsus: 1.20. Tarsal claw IV: 0.15. Epigynum: 0.365. Epigynal ventral plate with short transverse slit, indentation absent; atrium rectangular, two-thirds intruded by slightly rounded dorsal plate, atrial aperture moderate; bursa not enlarged nor fused; copulatory ducts separated at mid-point, reaching over primary lobe apex; copulatory ducts constriction located medially; primary pores visible (1 seen); stalk short, straight, horizontal, joining the primary lobe at the aperture of the dictynoid pore; dictynoid pore rounded; primary lobe kidney-shaped; secondary lobe absent; fertilization canal long, externally positioned from dictynoid pore; fertilization duct medially attached to the primary lobe base.
Distribution. Only reported from the type locality: Whiteface Cave (San Saba County, Texas, Fig. 130).
Remarks. Male unknown. The data given in Gertsch (1992) “ 30 mi. South” slightly differs from the data found on the label. The description of the epigynum is somewhat incomplete: the primary pore position is not given because these structures are displaced from their original position on the damaged holotype.
