Ivie(AMNH).    Diagnosis.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).    Remarks.  Titanebois herewith re-elevated to full genus status; for a justification see remarks on  Ebo.  Titanebospecies from North America were thoroughly revised by Schick (1965)and Sauer and Platnick (1972).   Compositionand distribution.The genus comprises 14 Nearctic species:  Titanebo albocaudatus( Schick, 1965),  T. andreaannae( Schick, 1965),  T. californicus Gertsch, 1933,  T. cantralli( Sauer & Platnick, 1972),  T. cresotis( Schick, 1965),  T. dispar( Schick, 1965),  T. dondalei(Sauer, 1968),  T. macyi Gertsch, 1933,  T. magnificusChamberlin & Ivie, 1942,  T. mexicanus(Banks, 1898),  T. oblongus( Simon, 1895),  T. parabolis( Schick, 1965),  T. redneri( Cokendolpher, 1978), and  T. texanus Gertsch, 1933. The primary centre of distribution is presumably the desert and shrub region of the southwestern Nearctic ( Schick 1965). 2611466313 1934-05-12 1962-06 1934-05-12 K. W. Haller & W. J.
