Oaxaca : Monte Albán [ N17.0438° , W96.76811° ], P. Brignoli , 7.viii.1973 , 1♂ ( MCVR ). REMARKS: Alayón (1981) described this species under Filistata stating that Lehtinen’s (1967) decision to erect Kukulcania for New World filistatines was not well justified and that additional studies on the phylogenetic relationships of the family were necessary. He did not explicitly state his reasons to doubt the validity of Kukulcania . The possession of sclerotized bars in the spermathecae of K. brignolii is a character so far recorded only in Kukulcania , indicating this species belongs here and not in Filistata . Hence, a new combination is proposed. With this transfer, all American species once placed in Filistata have been accommodated in New World genera. In the years before the publication of Alayón’s (1981) work, W.J. Gertsch recognized this species under the manuscript name “ Filistata tehuana . ” DIAGNOSIS: Males are similar to those of K. mexicana and K. santosi in having incrassate, strong setae in the prolateral border of the cymbium. They differ in having a short, uncoiled embolus (long, two coils in K. mexicana ) and by the simple apex of the incrassate setae on the cymbium (fig. 58) (spatulate in K. santosi ). Females are similar to K. mexicana in having long, curved sclerotized bars that do not taper posteriorly, and spermathecae that project anteriorly to the margin of the uterus externus. K. brignolii might be distinguished by the smaller glandular portion of the spermathecae apex, which is placed ventrally to the membranous portion (larger, ectally placed glandular portion in K. mexicana ), and by the usually less bent sclerotized bars (fig. 60).

Sclerotized lateral bars present, elongate, slightly curved, positioned posteriorly to receptacles; membranous portion of the spermathecae apex subrounded; glandular portion positioned ventrally to the membranous portion. State of the specimen: good, many setae missing, right legs I and II missing from tibia, genitalia dissected. INTRASPECIFIC VARIATION: Males ( N = 2): total length 7.45–8.34 (7.9), carapace length 3.36–3.71 (3.54), femur I length 7.21–7.46 (7.34), tibia I length 6.98–7.29 (7.14), femur/ carapace ratio 2.01–2.15 (2.08). Females ( N = 5): total length 10.29–12.77 (12.14), carapace length 4.55–5.6 (5.08), femur I length 5.05– 6.34 (5.85), tibia I length 4.9–6.08 (5.6), femur/ carapace ratio 1.11–1.26 (1.15). The shape of the female genitalia is variable, especially the shape of the sclerotized bars (fig. 60), and some specimens are somewhat intermediate with the morphology found in K. mexicana , sp. nov. , although these have been collected in areas with males or females with typical morphology (fig. 60H).
