description: Genus <i>Titanebo</i> Gertsch, 1933 <i>Titanebo</i> Gertsch, 1933: 10-11. <i>Ebo</i> (<i>Titanebo</i>) Gertsch, 1933 – Schick 1965: 73-75 (relegated to subgenus level); Sauer and Platnick 1972: 36. <i>Ebo</i> Keyserling, 1884 – Dondale and Redner 1978: 29-30 (ad part.). Type species. <i>Titanebo macyi</i> Gertsch, 1933 by original designation. <b>Material examined.</b> <i>Titanebo albocaudatus</i> (Schick, 1965): USA: Texas: 1♁, Abilene, 32° 27’N, 99° 46’W, June 1962, leg. K. W. Haller (AMNH); 1&amp;female;, Quemado, 28° 56’N, 100° 37’W, leg. W. J. Gertsch et al. (AMNH). MEXICO: Coahuila: 1♁, La Gloria, 26° 41’N, 101° 22’W, 24 August 1947, leg. W. J.

Ivie (AMNH). <b>Diagnosis.</b> Philodromid spiders with moderately enlarged AME (AME size index 0.054 -0.076) and strongly elongated leg II (Leg II length index 1.4-1.7). Prosoma as wide as long (Fig. 12). Clypeus of intermediate height (Clypeus height index 0.14-0.18, Fig. 8). Leg formula 2413 (occasionally 2143, but then leg IV almost as long as leg I). Spination of leg I: femur dorsal 0-1-1, prolateral 0-1-1-[01]; tibia ventral 2-2-0, pro- and retrolateral [01]-1-1, dorsal 0-0-1; metatarsus ventral 2-2-0, pro- and retrolateral [01]-1-1, dorsal 0-[01]. Metatarsus III and IV ventral 2-2-2. Patella of male palp without apophysis, tibia with two well developed apophyses, VTA a colourless lobe in close contact to the heavily sclerotized RTA, tip of RTA pointed and dentated. Embolus curved, its elongated, filiform tip pointing to RTA (Fig. 3). Tegulum without apophysis. Conductor in form of elongate retrolateral groove. Epigyne weakly sclerotized, without atrium or grooves. Vulva (Fig. 5) lateral and anterior of receptacula with long, sclerotised introductory tubes (= bursa copulatrix) on which the glandular heads (=spermathecal organs) sit, thus becoming copulatory ducts in the distal part. Receptacula with glandular mounds (=torus, Fig. 6). <b>Remarks.</b> <i>Titanebo</i> is herewith re-elevated to full genus status; for a justification see remarks on <i>Ebo</i>. <i>Titanebo</i> species from North America were thoroughly revised by Schick (1965) and Sauer and Platnick (1972). <b>Composition and distribution.</b> The genus comprises 14 Nearctic species: <i>Titanebo albocaudatus</i> (Schick, 1965), <i>T. andreaannae</i> (Schick, 1965), <i>T. californicus</i> Gertsch, 1933, <i>T. cantralli</i> (Sauer &amp; Platnick, 1972), <i>T. cresotis</i> (Schick, 1965), <i>T. dispar</i> (Schick, 1965), <i>T. dondalei</i> (Sauer, 1968), <i>T. macyi</i> Gertsch, 1933, <i>T. magnificus</i> Chamberlin &amp; Ivie, 1942, <i>T. mexicanus</i> (Banks, 1898), <i>T. oblongus</i> (Simon, 1895), <i>T. parabolis</i> (Schick, 1965), <i>T. redneri</i> (Cokendolpher, 1978), and <i>T. texanus</i> Gertsch, 1933. The primary centre of distribution is presumably the desert and shrub region of the southwestern Nearctic (Schick 1965).
