Genus Dianattus C. Wang, Mi & Li gen. nov.

Type species.

Dianattus proszynskii sp. nov.

Diagnosis.

Dianattus gen. nov. resembles that of Yaginumaella Prószyński, 1979 in having a very similar habitus and epigynal structure, but differs in: 1) the tegulum has a process near the embolic base and lacking a posterior lobe (Fig. 5 B) vs lacking similar process and having a posterior lobe in Yaginumaella (Figs 7 B, 9 B, 11 B, 13 B, 15 C); 2) the presence of clusters of ventral dense setae on metatarsi I, femora I, II, patellae I, II, and tibiae I, II (Fig. 6 G) vs absent in Yaginumaella (Żabka 1981: fig. 3; Wang et al. 2023 a: 23 A; Wang et al. 2024 b: fig. 46 C); 3) the copulatory ducts are forming arc-shaped portions on the bilateral sides of copulatory openings (Fig. 6 B) vs posteriorly extending from the origin in Yaginumaella (Figs 8 B, 10 C, D, 12 B, 14 B, D, 16 B).

Description.

See description of type species.

Composition.

The genus is monotypic presently.

Distribution.

China (Yunnan).

Etymology.

The generic name is a combination of dian, the pinyin of a short Chinese name of Yunnan Province, the type locality of the type species, and attus, meaning jumper. The gender is masculine.

Comments.

Yaginumaella pilosa Żabka, 1981 comb. rest. shares a very similar palpal structure with the type species, which indicates it could be a potential member of the genus. However, its generic position cannot be confirmed entirely due to the lack of other essential characteristics, such as habitus. Based on that, it has not been transferred into the genus, but further taxonomic attention is necessary.
