Patella I and II with two dorsal spines and one prolateral spine, patella III and VI with two dorsal spines, one prolateral spine, and one retrolateral spine. Leg tarsi with five to eight trichobothria. Capsulate tarsal organ distad of trichobothrial row ( Fig. 8 View FIGURE 8 f). Pedipalp femur with two to four dorsal spines. Female pedipalp tibia usually with one + two prolateral spines. Male pedipalp tibia with two to four spines and with prolateroventral protuberance and retrolateroventral groove ( Fig. 10 View FIGURE 10 e). RTA of male pedipalp with distal and dorsal projections; ventral projection usually present ( Fig. 21 View FIGURE 21 d). Embolus a short and simple curve ( Fig. 14 View FIGURE 14 a). Conductor with two short projections ( Fig. 3 View FIGURE 3 c). Median apophysis spoon-shaped ( Fig. 10 View FIGURE 10 a) (only reduced in N. alamo , Fig. 16 View FIGURE 16 d). Tegular median process present ( Fig. 21 View FIGURE 21 b). Fulcrum absent (only present in N. annamae , Fig. 2 View FIGURE 2 a). Female epigynal plate wider than long ( Fig. 25 View FIGURE 25 c). Atrium on posterior part of plate, usually wider than long ( Fig. 30 View FIGURE 30 f). Atrial spurs usually present ( Fig. 5 View FIGURE 5 a) (absent in N. calavera , N. lutzi , and N. garnica ). Internal genitalia with copulatory ducts strongly sclerotized, straight ( Fig. 23 View FIGURE 23 a) or curved ( Fig. 14 View FIGURE 14 d). Spermathecae bipartite ( Fig. 36 View FIGURE 36 ); primary spermathecae longer than wide ( Fig. 32 View FIGURE 32 d), secondary spermathecae blind-ended receptacles with primary pores ( Bennett 1992) and each connected to the union of copulatory duct and primary spermathecae by short diverticulum ( Fig. 14 View FIGURE 14 b). Fertilization ducts short, originating from the posterior part of spermathecae ( Fig. 10 View FIGURE 10 d).

Habitat. In North America, Novalena spiders are usually found in webs under loose bark of standing trees and stumps in dense coniferous forest, and occasionally in webs on the ground in shaded areas ( Roth & Brame 1972).

In tropical montane cloud forests of southeastern Mexico, they are found in webs within epiphytes and on understory vegetation and the ground.

Distribution. Novalena is widely distributed in the western Nearctic and northern Neotropics from southwestern Canada to Costa Rica and Trinidad and Tobago (Maps 1–8).
