9E712250A45150FBB15B3F9C2B1ED9F8.taxon	etymology	Etymology. The generic name Chicosa is a combination of the Mandarin Pinyin chi (from 螭, chī, a hornless dragon in Chinese mythology) and the common lycosid suffix - cosa (from Greek kósos, meaning ‘ creature’). The gender is feminine.	en	Tao, Ze-Hong, Fu, Dan, Wu, Chang-Jun, Wang, Yang, Liu, Li-Juan, Luo, Yu-Fa (2025): Chicosa gen. nov. (Araneae, Lycosidae), a new genus of wolf spiders from East Asia.

9E712250A45150FBB15B3F9C2B1ED9F8.taxon	diagnosis	Diagnosis. Chicosa gen. nov. is distinguished by the following combination of characters. Terminal apophysis (TA) well-developed, hook-shaped (Figs 1 A, E, 2 A, E); embolus (EM) originates low, extends transversely, then twists retrolaterally before curving to anterior part of bulb (Figs 1 C, D, E, 2 A, B, D); median apophysis (MA) undivided, cymbiform (Figs 1 C, E, F, 2 A, B, E). Median septum (MS) inverted T-shaped (Figs 1 H, 3 A); copulatory ducts (CD) extremely long, spirally coiled (Figs 1 G, 3 B, C). Differs from Alopecosa in: MA cymbiform and entire (vs. typically bipartite), TA hook-shaped (vs. often dentiform), EM basally originating (vs. non-basal), and CD extremely long and spiral (vs. shorter and simpler). Differs from Pardosa C. L. Koch, 1847 in: MA cymbiform and entire (vs. usually bipartite), TA hook-shaped (vs. dentiform), and EM basally originating (vs. non-basal). Although sharing two retromarginal cheliceral teeth with Pardosops Roewer, 1955, Chicosa exhibits a more complex palpal organ: MA cymbiform (vs. short and robust), TA elongate and hook-shaped (vs. two spinose processes). Differs from Acroniops Simon, 1898 in possessing four eyes (vs. two) in the anterior row. Distinguished from Chorilycosa Roewer, 1960 by the straight (vs. recurved) anterior eye row and hook-shaped TA (vs. two distinct spines). Differs from Leimonia C. L. Koch, 1847 in the straight anterior eye row with subequal width to second row (vs. strongly recurved and wider). Differs from Draposa Kronestedt, 2010 by the undivided, cymbiform MA with a single acute apex bent ventrolaterally (vs. MA transversely extended, with broad base bearing processes and narrow distal part bearing a small subapical projection), and the complete inverted T-shaped MS (vs. epigynal atrium only partially divided by a tongue-like septum). Differs from Wadicosa Zyuzin, 1985 in: retromargin with two teeth (vs. three), subtegulum small and positioned directly below tegulum (vs. large and anteroventrally shifted), TA without spiral torsion (vs. strongly twisted), and EM originating low and extending transversely (vs. originating antero-apically); female with distinct inverted T-shaped MS (vs. absent).	en	Tao, Ze-Hong, Fu, Dan, Wu, Chang-Jun, Wang, Yang, Liu, Li-Juan, Luo, Yu-Fa (2025): Chicosa gen. nov.
