Wulinggone Irfan, Zhang & Peng

Wulinggone Irfan, Zhang & Peng , gen. n.

(KWēeø)

Type species: Wulinggone qizimeiensis sp. n.

Etymology. This genus name derives from the type localities present in "Wuling Mountains range" and the second part taken from genus “ Erigone ”. Gender is feminine.

Diagnosis. Wulinggone gen. n. can be diagnosed by the tibia with three apophyses (DTA, PTA and RTA); radix with well developed embolic division, semicircular embolus and sclerotized anterior radical process; embolic membrane absent ( Figs 288A–D View FIGURE 288 ). Female can be distinguished by the dorsal completely exposed in ventral view ( Figs 289A, B View FIGURE 289 ); copulatory opening present at the junction of dorsal and ventral plate posteriorly ( Figs 289A, B View FIGURE 289 ); copulatory ducts form a coiled loop mid dorsally before entering the spermathecae ( Figs 289B, C View FIGURE 289 ); spermathecae elongated, tip slightly curved extending anteriorly ( Figs 289B, C View FIGURE 289 ).

Description. Same as for type species.

Remarks. The male of Wulinggone gen. n. resembles those of genera Araeoncus , Diplocentria , Diplocephalus , Islandiana , Laminacauda , Lophomma , Savignia , Sciastes , Spelaeus gen. n., Tmeticus , Typhochrestus , in having the palp with similar anterior redical process ( Hormiga 2000, figs 1, 2, 5, 6, 17, 18, 20, 24, 25, 29, 30; Figs 240 View FIGURE 240 , 241 View FIGURE 241 ). It also resembles Shaanxinus in having the both anterior redical process and lateral extension of radix (Lin et al. 2019, figs 3a–d), but can be distinguished by the lateral extension of radix present in Wulinggone gen. n. ( Fig. 288A View FIGURE 288 ; vs. absent in all of the Araeoncus , Diplocentria , Diplocephalus , Islandiana , Laminacauda , Lophomma , Savignia , Sciastes , Spelaeus gen. n., Tmeticus , Typhochrestus ); anterior radical scaly part absent in Wulinggone gen. n. ( Fig. 288A View FIGURE 288 ; vs. all of the other genera Araeoncus , Diplocentria , Diplocephalus , Islandiana , Laminacauda , Lophomma , Savignia , Sciastes , Spelaeus gen. n., Tmeticus , Typhochrestus ; present in Shaanxinus ). The female of Wulinggone gen. n. resembles that of genus Typhochrestus in having most of dorsal plate visible in ventral view ( Figs 289A–C View FIGURE 289 ; Bosmans 2008, figs 7, 8, 24, 25, 30, 31, 42, 43), and can be distinguished by the copulatory ducts forming long loop coiled around spermathecae in Wulinggone gen. n. ( Figs 289B, C View FIGURE 289 ; vs. extending anteriorly and not coiled around spermathecae in Typhochrestus ).

Composition. Wulinggone gen. n. belongs to the subfamily Erigoninae and here erected monotypic genus to accommodate W. qizimeiensis sp. n..

Distribution. Known only from the type localities (Chongqing and Hubei Province, Figs 307 View FIGURE 307 , 313 View FIGURE 313 ).
