Diagnosis. The genus is diagnosed by the following characteristics in combination: the male pedipalp with a short and simple curved embolus (Figs. 3 b, 13a, 18a, 32a, 43d); conductor with two projections (Figs. 3 c, 10a, 14c, 27a, 41f); tegular median process present (Figs. 10 a, 13a, 26a, 34d, 38a); RTA with distal and dorsal projections, ventral projection usually present (Figs. 3 d, 11b, 16m, 30e, 33e) (absent in N. shlomitae, N. simplex, N. chamberlini, N. cintalapa, N. gibarrai, N. oaxaca, and N. tacana, Figs. 15 b, 18b, 32b); atrium posteriorly located on the epigynal plate, wider than long (Figs. 5 a, 13c, 19c, 24d, 40a), and usually lacking a division (if divided [N. calavera and N. lutzi] then copulatory openings visible in posterior view, Figs. 7 e, 12e); atrial spurs usually present (Figs. 5 d, 15c, 24a, 33a, 42c) (absent in N. calavera, N. lutzi, and N. garnica, Figs. 7 c, 12c, 26c); short and strongly sclerotized copulatory ducts, straight or curved (Figs. 5 b, 14d, 20b, 36a, 38d), connected ectally to longer than wide primary spermathecae (Figs. 5 e, 10b, 15d, 25d, 31d); secondary spermathecae blind-ended receptacles with primary pores and each connected to the union of copulatory duct and primary spermathecae by short diverticulum (Figs. 10 f, 14f, 30g, 36b, 44e); and short fertilization ducts (Figs. 2 d, 13d, 22d, 31d, 39d).
Novalena differs from Eratigena Bolzern et al. 2013 and Tegenaria Latreille 1804 in having strongly procurved eye rows in frontal view; from Agelenopsis Giebel 1869, Barronopsis Chamberlin & Ivie 1941, Melpomene, and Tortolena Chamberlin & Ivie 1941 in lacking both a strongly modified embolus and projecting tegular lateral process in males (= tegular apophysis, Stocks 2009: fig. 39), and lacking long, membranous and plicate copulatory ducts in females (as in Stocks 2009: figs. 52, 61); from Calilena Chamberlin & Ivie 1941 in lacking a membranous fulcrum (as in Chamberlin & Ivie 1941: figs. 68, 70, 74) (only present in N. annamae) and an epigynal scape (as in Chamberlin & Ivie 1941: figs. 48–60); from Hololena (Chamberlin & Gertsch 1929) in lacking a fulcrum supporting the embolus (as in Chamberlin & Ivie 1942: figs. 6, 11, 12) and an anteriorly located epigynal atrium (as in Chamberlin & Ivie 1942: fig. 10); from Rothilena Maya-Morales & Jiménez 2013 in lacking three projections on conductor (as in Maya-Morales & Jiménez 2013: fig. 18) and spherical primary spermathecae (as in Maya-Morales & Jiménez 2013: fig. 29); from Rualena in lacking a membranous fulcrum (as in Maya- Morales & Jiménez 2016: fig. 43) and an atrium as long as wide (as in Maya-Morales & Jiménez 2016: fig. 30); and from Hoffmannilena in lacking a basal projection on RTA (as in Fig. 45 b, c) and a strongly sclerotized epigynal plate (as in Maya-Morales & Jiménez 2016: fig. 116).
Description. Medium-sized spiders, 4–14 mm total length. Eight eyes in two rows strongly procurved in frontal view (Fig. 8 b). Carapace with two symmetrical longitudinal dark bands intensified by feathery scales and a black band around the border of thoracic region (Fig. 1 c, i, r). Chelicerae with three promarginal teeth and two to four retromarginal teeth (Fig. 8 c). Sternum longer than wide (Fig. 1 f). Feathery scales present on carapace, opisthosoma, pedipalps, and legs (Fig. 8 a, b). Opisthosoma oval with dorsal foliate pattern and/or posterior chevrons (Fig. 1 b, k, s). Colulus divided with few hairs on each side (Fig. 9 c). PLS longest with distal segment 0.5– 1.25 times basal (Figs. 1 f, 9a). Legs formula usually 4123. Legs usually annulated (Fig. 1 b–d, k). 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 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 e). RTA of male pedipalp with distal and dorsal projections; ventral projection usually present (Fig. 21 d). Embolus a short and simple curve (Fig. 14 a). Conductor with two short projections (Fig. 3 c). Median apophysis spoon-shaped (Fig. 10 a) (only reduced in N. alamo, Fig. 16 d). Tegular median process present (Fig. 21 b). Fulcrum absent (only present in N. annamae, Fig. 2 a). Female epigynal plate wider than long (Fig. 25 c). Atrium on posterior part of plate, usually wider than long (Fig. 30 f). Atrial spurs usually present (Fig. 5 a) (absent in N. calavera, N. lutzi, and N. garnica). Internal genitalia with copulatory ducts strongly sclerotized, straight (Fig. 23 a) or curved (Fig. 14 d). Spermathecae bipartite (Fig. 36); primary spermathecae longer than wide (Fig. 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 b). Fertilization ducts short, originating from the posterior part of spermathecae (Fig. 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).
