9209E22E5BE6500C9863D8C00900C6F1.taxon	diagnosis	Diagnosis. This genus resembles Xerolycosa Dahl, 1908, another genus within subfamily Evippinae. Species of both genera lack a transverse depression on the carapace (Fig. 2 A, B), tibia I and II with three pairs of ventral spines (Fig. 2 E, F), and male palps with a bifid terminal apophysis (Fig. 2 G, H). Halocosa can be distinguished by the presence of three retromarginal cheliceral teeth in Halocosa (Fig. 2 C, D; vs. with two teeth in Xerolycosa); embolus lacking accompanied membrane (Fig. 2 C, D; vs. present in Xerolycosa); strong or small tegular sclerite, bifid terminal apophysis (anterior arm strong and sclerotized, posterior arm thin and membranous) in Halocosa (Figs 3 A, B, 4 C – F, 5, 6 A, B, 7 E, F, 8; vs. both are membranous in Xerolycosa); wide square or rectangular septum covering whole atrium in Halocosa (vs. pear-shaped, partly covering atrium in Xerolycosa); slit-like copulatory openings, presence of accessory tube-like glands in Halocosa (Figs 3 C, D, 4 G, H, 6 C, D, 7 G, H; vs. glands absent in Xerolycosa).	en	Wang, Lu-Yu, Irfan, Muhammad, Marusik, Yuri M., Zhang, Zhi-Sheng (2024): Review of the wolf spider genus Halocosa Azarkina & Trilikauskas, 2019 from China (Araneae, Lycosidae).

9209E22E5BE6500C9863D8C00900C6F1.taxon	description	Description. Medium sized (6.4 – 13.21) (Azarkina and Trilikauskas 2019) light colored. Carapace dirty brown with pattern formed by yellowish spots: butterfly like spot around fovea, pair of bean-shaped spots posteriorly from eye field and three pairs of marginal round spots; sternum brown; dorsum of abdomen with variegated pattern formed by numerous paired and unpaired spots on dirty brown background, venter uniformly yellow. Carapace very low (length / height ratio c. 4), furrow between cephalic and thoracic parts absent. Chelicera with three pro- and three retromarginal teeth. Leg formula: 4123 or 4132. Femora I – IV with three dorsal spines, patella with one dorsal, tibia and metatarsi III and IV with two dorsal spines (not indicated in tables). Within the intraspecific, the dorsal spines on tibia and metatarsus can be strong or weak, almost indistinguishable from large setae. Palp with droplet-shaped cymbium, subtegulum (St) small, placed on prolateral side; tegulum large, going rather high on prolateral side with long ridge (Tr) on prolateral side that hold and hide part of embolus (Em); retrolateral part of tegulum with extension directed anteriorly, terminating by conductor, median part with tegular sclerite (TS); seminal duct thin, with “ sharp ” loop (Sl) on prolateral half; median apophysis located closer to retrolateral part of tegulum, without extensions, inner side of median apophysis with kind of pocket (or furrow) (MA), that holds tip of embolus and seems to serve as functional conductor; in retrolateral view median apophysis concave; embolic division with large sharply pointed terminal apophysis (TA) accompanied by membranous subterminal apophysis (SA); embolus long whip-like, smoothly rounded, slightly bent near tip, making almost whole circle, partly hidden by tegular ridge and median apophysis, base of embolus located in position of 2 o’clock. Epigyne relatively small, one-fifth the width of the abdomen, densely covered with white setae to such extent that adult female could be considered as juvenile, especially in the field; fovea / atrium absent, totally covered with rectangular septum, septal stem absent, copulatory openings located in anterior part of epigynal plate, open into deep bulge which turns to wide, weakly sclerotized duct going straight down, near epigastral fold this duct turns up into strongly sclerotized, partly twisted, duct terminating by more or less clavate spermatheca; heavily sclerotized part of duct with finger-like or clavate accessorial gland (Ag).	en	Wang, Lu-Yu, Irfan, Muhammad, Marusik, Yuri M., Zhang, Zhi-Sheng (2024): Review of the wolf spider genus Halocosa Azarkina & Trilikauskas, 2019 from China (Araneae, Lycosidae).
