Diagnosis
Male TER not bent posteriorly, directed retrolaterally. Contrasts with L. gesserit sp. nov. by having TAT as long as CTA (TAT as shorter than CTA in L. gesserit). Contrasts with all other known males of Lycosa, with TER bent posteriorly (Figs 2C, 3C, 4C, 5C, 6C, F, 7C, 19).
Female
Recognized by combination of characters: ocular area:>⅓ length of carapace, distinctly raised, making the carapace between PLE and fovea appear slightly concave in profile. Epigyne: septal pedicel reduced, septum trapezoidal, broader proximally, wider than long. Copulatory openings narrow, at anterior end of septum. Carapace resembles L. oculata, L. suboculata, and L. macrophthalma, but in these species the septum is longer than wide. Carapace also resembles Lycosa sp., but in this species the copulatory openings are not visible in ventral view. Epigyne similar to L. piochardi and L. baulnyi, but in these species the ocular area is not distinctly raised, and is <⅓ length of carapace (Figs 6C, F, 7C, F, 9B, 10B, 11C–D).
Etymology
Species name from Hyrax. This species often leaves the entrance to its burrow open. This behavior reminded the authors of an Israeli nursery rhyme, in which “the little hyrax forgot to close the door”.

Natural history
This species is nocturnal. Females were collected March, June, August and September. Males collected June, August and September. Subadult females were collected April and June. Subadult males were collected May, July and September. Juveniles were collected January, June, July and October (Table 4). Reproductive season unknown. This species inhabits loess soils in arid desert environments (annual precipitation 75–200 mm). The burrow usually with a modification in the form of a thin, flexible door made of silk and soil, and hinged to the entrance with silk. Rarely an object such as a piece of soil crust or a flat stone can be used as a door. The door is often left open. The spiders are usually found at night, standing near the burrow, rarely on rocks or vegetation. Captive specimens accept a wide variety of insects, similar to other species of Lycosa (Steves et al. 2017) (Figs 8C–D, 21B, 22B).
Distribution
EGYPT, ISRAEL.
Records
EGYPT: Sinai (Al-Qusaymah (Kadesh Barnea)). ISRAEL: Negev (Ha-Ro’a Campsite, Haluqim ridge, Hawat Even Ari, Mamshit, Midreshet Ben-Gurion, Mishor Yamin, Sede Zin, Shivta camp, Yeruham) (Fig. 1).
Relationships
According to our molecular phylogey, this species is the sister taxon of Lycosa gesserit sp. nov., and closely related to Lycosa oculata, Lycosa aff. oculata 1 and Lycosa aff. oculata 2. The cephalothorax is morphologically similar to Lycosa macrophthalma Nadolny & Zamani, 2020 and the species might be related to it as well (Figs 23–24).
