ETYMOLOGY: Tequila is one of the localities where the species is known to occur. The name is to be treated as a noun in apposition.

DESCRIPTION: Gertsch recognized this species under the manuscript name “ Filistata hespera .”

DIAGNOSIS: Males are easily distinguished from all Kukulcania by the distinct twisted shape of the palpal bulb, more easily seen in apical view (fig. 74D, F). Females are similar to K. tractans in having spermathecae with a short membranous stalk and a large, sclerotized glandular portion of the spermathecae, lacking a membranous portion of the spermathecae. K. tequila can be distinguished by the longer membranous stalk and by the more slender and ventrally curved glandular receptacle portion of the spermathecae (figs. 31F– G, 76). The legs and sternum of K. tequila are also less hirsute than those of K. tractans , lacking the characteristic dense fringe of the latter species.

DESCRIPTION: Male paratype from Lake Chapala, Ajijic, Jalisco (AMNH IFM-1549). Coloration brownish yellow. Carapace finely stippled with light brown. Abdomen dorsum light brown; venter with light markings alongside spinnerets. Clypeus short. Sternum oval, with two pairs of sigillae. Total length 7.78.

Palp: cymbium long, bearing a brush of strong setae on the retrolateral face; bulb oddly shaped, twisted, and curved retrolaterally; sperm duct with four coils, distally sinuous; embolus long, curved but uncoiled.

Female paratype from 50 miles north of Culiacán, Sinaloa, Mexico (AMNH IFM-1650). Coloration very dark, reddish brown. Carapace with median area and borders more densely stippled with brown. Sternum and legs not particularly hirsute. Leg coxae and femora with longitudinal, brown stripes. Abdomen dorsum grayish brown. Anterior margin of the carapace unmodified. Sternum oval, with two pairs of sigillae. Total length 9.9. Carapace length 4.33, width 3.18, clypeus length 0.68. Eye diameters and interdistances: AME 0.22; PME 0.234; ALE 0.301; PLE 0.284; AME– AME 0.014; PME–PME 0.287. Sternum length 1.94, width 1.76. Palp: femur length 2.16, height 0.87; tibia length 1.2, height 0.82. Leg I: femur (fe) 4.7; patella (pa) 1.5; tibia (ti) 4.2; metatarsus (mt) 3.8; tarsus (ta) 1.9.

Palp macrosetae on ventral surface of tibia and tarsus. Leg macrosetae present on ventral surfaces of tibiae, metatarsi and tarsi; fourth femora with two dorsal macrosetae. Calamistrum with three rows of 9–11 setae each. Interpulmonary fold large, rounded, covering the spermathecae dorsally. Spermathecae with a single pair of receptacles, each with a membranous stalk and a sclerotized apex gently curved ventrally, sclerotized lateral bars absent. State of the specimen: good.

INTRASPECIFIC VARIATION: Females (N = 7): total length 8.03–13.04 (10.18), carapace length 2.76–5.76 (4.06), femur I length 2.99–5.87 (4.28), tibia I length 3.01–5.33 (4.1), femur/carapace ratio 0.96–1.13 (1.06). The shape of the palpal bulb is slightly variable (fig. 74). Spermathecae vary in the length of the membranous stalks and the sclerotized receptacle apices (fig. 76). Some specimens have the receptacle apices only slightly curved ventrally (fig. 76E–F).

NATURAL HISTORY: A male specimen has been collected in a house.

DISTRIBUTION: Western coastal states of Mexico, from Sinaloa to Guerrero (fig. 4B).
