Cicurina coahuila Gertsch 1971: 110 View in CoL , fig. 108 (description of female). — Brignoli 1972: 151; Reddell 1973: 33, 38; Hoffman 1976: 46; Reddell 1981: 135; Reddell 1982: 264; Gertsch 1992: 120, figs 163–164.

HOLOTYPE female: “ Coahuila; Cueva de los Lagos, 15 mi west of Ciudad Acuna & 2 mi. N of the Rio Grande at Diablo Cave , 23 January 1964. J. Reddell, D. McKenzie, J. Porter. In small domes”. Label 2 added by Gertsch: “ Coahuila; Cave 15 mi. W. Ciudad Acuna w101.n29. J. Reddell, D. McKenzie, J. Porter ”. Examined ( AMNH).

Description. Female holotype

Total length: 3.10; carapace length: 1.35; carapace width: 0.75. Eyes absent. Cheliceral promargin right side with 3 teeth (2 large, 1 small), left side likewise; retromargin right side with 5 denticles (2 large, 3 small) left side likewise. Leg I: total length: 3.78; femur: 1.10; patella: 0.43; tibia: 0.90; metatarsus: 0.80; tarsus: 0.55; leg IV: total length: 4.33; femur: 1.15; patella: 0.45; tibia: 1.05; metatarsus: 1.10; tarsus:0.58. Tarsal claw IV: 0.09. Epigynum: 0.280. Epigynal ventral plate with long transverse slit, indentation absent; atrium rectangular, half intruded by straight dorsal plate, atrial aperture large; bursa enlarged, not fused; copulatory ducts touching at midpoint, reaching over the primary lobe apex; copulatory ducts constriction located basally; primary pores not visible; stalk, long, acutely procurved, joining the primary lobe at the aperture of the dictynoid pore; dictynoid pore elongated; primary lobe light-bulb shape; secondary lobe present, positioned ventro-basally from primary lobe; fertilization canal very long, internally positioned from the dictynoid pore; fertilization duct medially attached to the primary lobe base.

Distribution. Only reported from the type locality, Cueva de los Lagos, Coahuila, Mexico ( Fig. 138).

Remarks. Male unknown. The data from the holotype label slightly differs from Gertsch’s (1992) type data. “In small domes” refers to the microhabitat on the ceiling of the cave (James R. Reddell, pers. comm.). Reddell (1981) mentioned that Cueva de los Lagos has unfortunately been inundated by the waters of the
