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).
