Citation: Muster C (2009) Th e Ebo-like running crab spiders in the Old World (Araneae, Philodromidae). In: Stoev P, Dunlop J, Lazarov S (Eds) A life caught in a spider's web. Papers in arachnology in honour of Christo Deltshev. ZooKeys 16: 47-73. Abstract A recent phylogenetic analysis within Philodromidae has shown that Ebo Keyserling, in its current limits, is a paraphyletic assemblage of spiders characterized by a strongly elongated second pair of legs and by enlarged anterior median eyes.
... erior median eyes. Here a generic revision of Ebo-like philodromid spiders is provided, with the genera Ebo, Titanebo Gertsch (re-elevated to genus rank), Halodromus gen. n. and Philodromus Walckenaer ad. part. (the histrio species group = Rhysodromus Schick) being redefi ned and diagnosed. Ebo and Titanebo are Nearctic taxa whose occurrence in the Old World remains doubtful. Old World species with a long patellar apophysis on the male palp are included in Halodromus gen. n. (H. patellaris (Wunderlich, 1987), H. patellidens (Levy, 1977) , both ex. Ebo). Th ree new species are described from both sexes, Halodromus barbarae sp. n. from the Arabian Peninsula, Egypt and Spain, H. deltshevi sp. n. from Yemen, and H. gershomi sp. n. from Eritrea. Ebo eremus Levy, 1999 is a new subjective synonym of Halodromus patellaris (Wunderlich, 1987) . Halodromus is presumably an Afro-Syrian element with wide distribution in the Eremial of northern Africa and the Middle East. Th e Israeli species Philodromus halophilus (Levy, 1977) , comb. n. ex. Ebo is transferred to the Philodromus histrio species group.
