Type. Holotype male: MEXICO: Oaxaca : Municipality of Santa María Jaltianguis, road to Ixtlán de Juárez, 1.6–8 km NE El Punto , 2286 m, 3.IX.1961, Millers and Bogerts, deposited at AMNH .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Novalena ixtlan can be distinguished from all other species by the presence of four rows of long and curved hairs on metatarsus and tarsus I and II ( Fig. 29).

Description. Male (holotype): Carapace orange, cephalic region reddish. Chelicerae and condyles reddish. Endites and labium dark brown with white tips. Sternum orange with a central yellow spot. Legs orange, metatarsus and tarsus darker. Rings barely perceptible. Opisthosoma dark brown with anterior spot, two lateral bands that connect on the middle part, and posterior yellow spots. Spinnerets light brown. Total length 11.63.

Carapace length 5.63, width 4.5, cephalic region width 2.14, ocular region width 1.19. Eye diameter: AME 0.23, ALE 0.29, PLE 0.19, PME 0.25.
