Xysticus grallator Simon, 1932 is a little-known species of crab spider distributed in the western Medi-terranean region. We present new records of this species from mainland Italy, together with images of living and preserved specimens, the copulatory organs, and the habitat. A map of literature records provides insights into the known distributio...
Spiders collected during field trips and by spontaneous hand-collecting throughout Georgia between the years 2006 and 2022 were determined to species level and partly characterized by genetic barcoding of the COI gene. Among the resulting 51 species, two are recorded for the first time from the entire Caucasus Ecoregion: Pireneitega armeniaca (Brig...

... The family Linyphiidae is one of the most diverse spider families worldwide, comprising 634 extant genera and 4,858 species, including 11 fossil genera and 62 species (WSC 2024). Currently, 532 species in 175 genera have been reported from China (Tanasevitch 2024), of which 37 species in 22 genera have been recorded in Chongqing Municipality (Irfan et al. 2022(Irfan et al. , 2023a(Irfan et al. , 2023b.

Four new species of the genus Tapinocyba Simon, 1884 are described from Jiangjin, Chongqing: T. centralissp. nov. (♂), T. denticulatasp. nov. (♂♀), T. triangularissp. nov. (♂♀), and T. virgasp. nov. (♂♀). The new species exhibit distinctive genital features, such as a bifurcated embolus tip in the male palp of T. denticulatasp. nov. and T. virgasp. nov., and embolus tip unbifurcated in T. centralissp. nov. The epigynes display more unique characteristics, such as epigynal plate with a pit ventrally on its frontal face in T. triangularissp. nov. and T. virgasp. nov., which is absent in all other known Tapinocyba species. Detailed descriptions, along with photographs of genital characters, somatic features, and a distribution map, are provided.
... Basal part of radix wider than distal end, slightly curved, with two apophyses RA-I robust, with irregular margins, with about 7 small teeth, RA-II rod-like, with blunt end; median membrane as long as the embolus, anterior proximal part of median membrane with 6 strongly sclerotized teeth; terminal apophysis wing-shaped; embolus elongated with sclerotized embolus proper. Irfan et al. 2023, figs 9A−D, 10A−E), but can be distinguished by the lower comb-shaped process of dorsal tibial apophysis with six teeth in D. modaoxiensis sp. n.

... n. can be differentiated from all other Erigoninae genera by the following unique combination of characters: 1) cephalic lobe absent rather than cephalic region elevated; cephalic pits conspicuous located behind the PLEs (Fig. 23A, B); 2) dorsal tibial apophysis with bifurcated apex, pointing retrolaterally in ventral view; 3) distal suprategular apophysis unmodified; 4) radix give rise to long curved embolus and round to oval anterior radical process (Fig. 21A-D); 5) paracymbium U-shaped, distal arm with hook-shaped tip (Fig. 21B). Female can be identified with unique structure as pair of lateral arms originate from the anterior margin of ventral plate of epigyne and extending posteriorly above the epigastric furrow, these lateral arms do not have any connection with the copulatory ducts or copulatory opening; ventral plate extending posteriorly above the epigastric furrow with copulatory opening as in genus Dicristatus Irfan, Wang & Zhang, 2023 (Fig. 22A-F; Fig. 9A-F). ...

(both sexes), Centromerus alatus sp. n. (male only), Dicristatus modaoxiensis sp. n. (both sexes), Hypselistes arcus sp. n. (male and female), Ryojius flosculus sp. n. (male only), R. latus sp. n. (male only), Shaanxinus shizhuziensis sp. n. (both sexes), Sinogone caesuma gen. & sp. n. (both sexes), and Walckenaeria hongqiensis sp. n. (both sexes).

A small series of spiders collected from a low mountain Phoenix in Liaoning Province of China, contains five linyphiid species, one of which, Platyspira scissa sp. nov. (♂, ♀), is described as new. The new species is similar to P. tanasevitchi Song & Li, 2009, known from caves in Guizhou Province, China. Habitus and copulatory organs of both sexes are illustrated for the new species, as well as for “Doenitzius” pruvus Oi, 1960. The taxonomic position of the genus Doenitzius Oi, 1960 is discussed. Distribution of each species is commented on.
Background
The genus Wuliphantes Irfan, Wang & Zhang, 2023 is a small genus in the family Linyphiidae Blackwall, 1859, with only three species: W.guanshan (Irfan, Wang & Zhang, 2022), W.tongluensis (Chen & Song, 1988) and W.trigyrus Irfan, Wang & Zhang, 2023, all distributed in China.
New information
A new species: Wuliphantesyaan sp. nov. from Sichuan Province, China is reported. In addition, we re-described the type specimens of W.tongluensis (Chen & Song, 1988) that is similar to W.yaan sp. nov.
