The Ebo-like running crab spiders in the Old World (Araneae, Philodromidae)

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. 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.

The Morphology And Phylogeny Of Dionychan Spiders (Araneae: Araneomorphae)

“…Hill and Richman (2009) had suggested such a relationship, by the uncommon enlargement of the direct median eyes of philodromids, notably so in the basal genus Ebo (see Muster, 2009a: figs. 7-10).…”

Solving a running crab spider puzzle: delimiting Cleocnemis Simon, 1886 with implications on the phylogeny and terminology of genital structures of Philodromidae

“…Identification of the material was carried out by comparison with type-material and consulting original species descriptions and other taxonomic works. Descriptions and terminology were adapted from current taxonomic papers dealing with Philodromidae and other spider families (e.g., [ 3 , 6 , 9 , 16 , 25 , 26 ]). A discussion on nomenclature and definitions of genitalic characters is given in the section “Notes on genitalic morphology of Philodromidae” below.…”

The state of biodiversity in Kuwait

“…Very little is known about the spiders of Kuwait. Two species of Latrodectus (Knoflach & Van Harten, 2002a & b), and one crab spiders (Muster, 2009) were reported (Table 17). Unidentified spiders epresenting jumping spider (Salticidae), long-legged spider (Pholcidae), orb-weaver spider (Araneidae) and wolf spider (Lycosidae) were reported from Wafra .…”
