Diagnosis Recognized by a combination of genital characters. Male palp: tegular apophysis small, translucent, oriented distad, parallel to plane of bulb, laterally barb-shaped ( Figs 6E , 7E , 8E ). Tegulum presents single sinus shape curve of sperm duct (in Evippa : two) ( Fig. 6E ). Epigyne: rounded or hat-shaped, wider than long, septum wide. Atria narrow, shallow, greatly constricted distally (in Evippa : width approximately equal throughout), similar to epigyne of E. squamulatum , but proximal portion of atrium wide (in E. squamulatum proximal portion of atrium slit-shaped) ( Figs 10E , 13B, D ). It is the only Evippinae in Israel covered in flat, leaf-shaped setae and without annulations on the legs.

Clypeus black near AME, light laterally, with white setae on margin. Chelicerae proximally yellow to orange with grey or brown reticulation connecting to oblique brown band in middle, retrolateral margin white.

Part of sperm duct visible through tegulum bent at 90°. Tegular apophysis small, translucent, oriented distad, with subapical process oriented ventrad; slightly elevated over tegulum ( Figs 6E , 7E , 8E ). LEGS. Tarsus without pseudoarticulation, but in some specimens tarsi bent. Metatarsus I ventral spination: 2 pairs of long spines (pair I not reaching pair II) + short apical triplet; tibia I ventral spination: 5 pairs (all long except 5 th pair) + short apical pair.

Clypeus yellow to brown, covered with leaf-like setae, with dark lateral bar. Chelicerae orange, with leaf-like setae on proximal half, sometimes with grey reticulation and oblique grey band. Legs yellow, usually, greyish on proximal side of segment, sometimes with grey line on dorsal side. Palps yellow, with some grey on femur and tarsus. Sternum brown.Abdomen dorsum yellow to whitish. Cardiac mark grey, usually with two lines of gray spots, connecting above spinnerets. Abdomen venter yellow, grey or white, darker on center. Book lungs white. Spinnerets yellow ( Fig. 5E ). CARAPACE. Ocular area elevated. Due to the females’ strongly raised cephalic region and short legs they resemble a juvenile Lycosa rather than an Evippa . CHELICERAL TEETH. 3 promarginal, 2 retromarginal. GENITALIA. Epigyne wider than long, septum wide, atria distinct, shallow, narrow, widening proximally. Spermathecae longer than atria, bent retrolaterally, shaped like a crookneck squash ( Figs 10E , 11E , 13B, D ). LEGS. No pseudoarticulation of the tarsus. Metatarsus I ventral spination: 2 long pairs (pair I reaching base of pair II); tibia I ventral spination: 5 pairs (long, except 5 th ) + short apical pair. Natural history Adult Evippomma simoni were collected April through June, August and September ( Table 3 ) and may have a yearly cycle similar to what was suggested for E. arenaria , with a period of lowered activity in the colder months of the year (see Discussion). A female with eggs (HUJ INV-Ar 20422) was collected in June. The species mostly inhabits sandy desert habitats ( Fig. 15B ). An anecdotal report raises the possibility that the species also exists along the coastal dune strip, similar to Evippa arenaria (Y. Salaviz, pers. com.). Specimen HUJ INV-Ar 20421 was found by S. Aharon in a silk-lined burrow ( Fig. 2 ), similar to what has been reported for E. rechenbergi ( Bayer et al. 2017 ) . Distribution Sudan (Alderweireldt 1992), Israel . Israel : Negev (Be’er Mash’abbim, Holot Agur, Nahal Sekher, Mamshit), Dead Sea area (Near Sedom) ( Fig. 16 ). Remarks This is the first record of Evippomma in Israel , and may also be the first record outside of Africa (depending on the dubious report of the species from India ( Roewer 1955 )). If there is a continuous distribution with the type locality at the northern Sudanese border, this species is to be present in the sandy desert of northern Sinai and in eastern Egypt . It may be distributed in other hot desert environments in the region, such as the sandy deserts of Jordan . Most of the specimens were collected in dune areas, but a specimen from the Sedom area, with a clayrich substrate, suggests that this species is not an obligate psammophile. Phylogenetic relationships of Evippinae based on COI and NADH The ML tree topology recovered the genus Evippa as monophyletic (bootstrap support [BS]= 89%). Evippinae was only moderately supported in our tree ( Fig. 17 ; BS =63%), yet the topology in our tree accords with the tree topology for Lycosidae in Piacentini & Ramírez 2019 and with the composition of Evippinae sensu Alderweireldt 1991 .
