Fig. 2. Phylogenetic tree of cytochrome c oxidase subunit I haplotypes of different species of Filistata Latreille, 1810 inferred under maximum likelihood. Numbers below branches are bootstrap supports. The histogram shows the distribution of pairwise Kimura two-parameter genetic distances within and between F. insidiatrix (Forsskål, 1775) and F. betarif sp. nov. (for pairwise distances of other species, see Table 2). Note that some intraspecific genetic distances within F. insidiatrix are larger than interspecific distances between F. insidiatrix and F. betarif sp. nov., denoting a lack of a barcode gap in this group, or cryptic species within F. insidiatrix.

Fig. 4. Distribution maps. A. Filistata insidiatrix (Forsskål, 1775) in the Mediterranean and Middle East (note the species has been recorded from Angola, Venezuela and the islands of Socotra, Azores and Cabo Verde, but these records seem to be introduced); literature records have been taken from Benoit (1968), Brignoli (1982), Marusik & Zonstein (2014), Marusik & Zamani (2015a) and Zonstein & Marusik (2019). B. Filistata insidiatrix (circles) and F. betarif sp. nov. (star) in Israel and Palestine; only specimens examined by us are included in the map. Darker shades of orange are records that include at least one male specimen. C. Other species of Filistata Latreille, 1810 in Israel (except F. insidiatrix).
