Remarks. Color macrophotographs and drawings disclose diversity of Israeli E. pseudogambosa , indicating possibly separate species status. Live E. pseudogambosa A from Givat Ram, studied in 1988 by Prószyński ( Figs 18A ), had ventral surfaces of femora I-II red, abdomen dorsally blackish brown, characters changing 8 * in alcohol speedily, in a few minutes, from black to light dotted black ( Fig. 18A ), beginning right from the moment of spider dying in alcohol. Photograph of E. pseudogambosa B ( Fig. 18C ) by Amir Weinstein of specimen observed in the Haifa area show femora I-II entirely black (which confirms drawing of leg I by Logunov ( Fig. 18B )). The diversity in this species in Israel corroborates observations of diversity in many other species, being presumably result of rapid proliferation of Salticidae in warm climate of that geographical area. Unfortunately such observations are rarely documented, due to rarity, as yet, of macrophotographic documentation.

Euophrys semiglabrata (Simon, 1868) is studied in a parallel paper ( Prószyński, Noordam, Oger & Schäfer (2018 – in press)) and transferred to a new genus of its own.

8 The first author watched unusually rapid change of dorsal pattern in Euophrys pseudogambosa immediately after submerging it in ethyl alcohol during preservation - there appeared streams of liquid, floating beneath transparent tegument, carrying a crowd of minute black globules, deposited later into different pattern of dots and lines, characteristic of Euophrys - but in fact artifacts. This is different from gradual bleaching of colors in other preserved Salticidae , a process lasting years.

Figure 4. Color pattern diversity in Euophrys and some other European genera. A - Euophrys frontalis male and female in nuptial dance, B - E. frontalis, male frontal and dorsal view (compare with - D - presence of white palpal mane may be misleading), C - E. gambosa, male frontal and dorsal view, D - white palpal mane in Hasarius adansoni is comparable with Euophrys frontalis (see Fig. 4B) [correction of misinformation in Prószyński. (2018a: 17)., E - E. pseudogambosa, F -Pseudeuophrys erratica, male, F1 -Pseudeuophrys vafra, female, G - E. sulfurea, male and female, frontal and dorsal views, H - E. petrensis, I - E. terrestris, J - E. rufibarbis, K - Talavera aequipes, L - Saitis barbipes - (note differences with Euophrys spp.: legs I & II thin, legs III thickened, with strikingly black "bottle-brush" of longer setae, tarsus III white), M - Chalcoscirtus infimus.

Figure 18. Separation of similar forms: A - Euophrys pseudogambosa A and B-C - E. pseudogambosa B, occurring in close geographical areas, is hampered by differences in style of diagnostic documentation and different preservation of specimens, photographs of live specimens helps in authentication 0f diagnostic drawings.
