Genus Zodariellum Andreeva & Tyshchenko, 1968 View in CoL View at ENA

Zodariellum Andreeva & Tystshenko, 1968: 688 View in CoL .

Zodariellum: Marusik & Koponen 2001: 40 View in CoL (removed from the synonymy of Zodarion View in CoL ).— Zamani & Marusik 2021: 184 View Cited Treatment .

Type species. Zodariellum surprisum Andreeva & Tyshchenko, 1968 View in CoL from Tajikistan, by original designation .

Emended diagnosis. Males of Zodariellum View in CoL differ from that of Zodarion nitidum (Audouin, 1826) View in CoL ( Fig. 11A– C View FIGURE 11 ), the generotype of Zodarion View in CoL , by having: 1) RTA ( Ra) longer than wide, with solid base and either bifurcated or solid tip, with branch or branches ( Rb) bent retrolaterally at more than right angle ( Figs 4A–D View FIGURE 4 , 5A–D View FIGURE 5 ) ( vs. wider than long and divided into 3 parts basally; Fig. 11B View FIGURE 11 ), 2) lacking ventral tibial apophysis ( vs. present, Va in Fig. 11A–B View FIGURE 11 ), 3) cymbium with short tip (i.e. as long as wide, shorter than RTA) and prominent tutaculum ( Tu) ( vs. tip longer than wide and longer than RTA, tutaculum absent), 4) large tegular apophysis ( Tg) longer that bulb, with prolateral spur ( Sp) located basally and directed postero-ectally, and long retrolateral arm ( Tr) with tip resting on tutaculum ( vs. tegular apophysis shorter than bulb), 5) very long conductor ( Cn), longer than bulb, with prolateral arm ( Cp) terminating at a 6 o’clock position or earlier ( vs. conductor lacking prolateral arm and shorter than bulb), and 6) longer filamentous embolus originating at a 6 o’clock position or earlier ( vs. 6:30). Females of Zodariellum View in CoL differ from those of Zodarion View in CoL sensu lato by the long, twisted (i.e. similar to a screw), converging copulatory ducts ( Fig. 10A–D View FIGURE 10 ) ( vs. not twisted or diverging if twisted).

Furthermore, males of Zodariellum View in CoL differ from those of all other zodariid genera by having a very deep (=long) diverticulum of cymbium ( Di, Fig. 2F View FIGURE 2 ) (about 0.4 time of cymbium length and 0.75 of cymbium width). The species of Acanthinozodium View in CoL also have a cymbial diverticulum, although in the form of a short conical (i.e. depth about one radius) round pit ( Jocqué & Henrard 2015: fig. 9A, B; Zamani & Marusik, 2021: figs 13C, 14G‒H, 15C, F, 21F, 22H‒I, 23C, 24C). Furthermore, the male palps of Zodariellum species have serrated processes of RTA and serrated spur of the tegular apophysis ( Sp), which have not been recorded in other Zodariinae genera.

Composition. 21 species (including those described here and the new combinations):

According to the shape of the RTA, the genus can be split into three species-groups:

1) furcum View in CoL species-group, comprising Z. furcum View in CoL and Z. planum ; in both species, RTA has a process arising from its mid part, and a pointed tip ( Zhang & Zhang 2019: figs 4E, 12C).

2) bactrianum View in CoL species-group, comprising Z. bactrianum View in CoL and Z. turanicum sp. n.; in both species, RTA has two processes originating posteriorly, and an abrupt tip ( Figs 2B, D View FIGURE 2 ).

3) surprisum View in CoL species-group, comprising the rest of the species with known males; in all species of this group, RTA has one or two processes, and a roundly or almost roundly bent tip ( Figs 2A, C, E View FIGURE 2 ).

Distribution. From Volga River’s delta to northeastern China, south to northeastern Iran and south China (ca 25ºN) ( Fig. 12 View FIGURE 12 ).
