Type material of Chinattus undulatus . Holotype ♀ ( IZCAS-Ar9262 ), China, Hubei Province, Lichuan County, Mt. Xingdou , 6.VI.1989, examined.

Type material of Chinattus szechwanensis . Holotype ♂ and allotype ♀, China, Sichuan Province, west of Yahow , ca. 6000–8000, VI.1923, D.C. Graham leg. All type specimens are deposited in Smithsonian Institute, Washington D.C., USA, not examined.

Type material of Chinattus emeiensis . Holotype ♀ and paratypes 2♀, China, Sichuan Province, Mt. Emei , VIII,1980, Xiaoen Chen leg. ; Paratypes 2♀, China, Guizhou Province, Qianling Park , 21.VII.1985, Chuandian Zhu leg. ; Paratype ♀, China, Sichuan Province, Mt. Qingcheng , 19.VIII.1978, Chuandian Zhu leg. All type specimens are deposited in Hunan Biology Research Institute, not examined .

Diagnosis. Females of this species are similar to Chinattus wulingensis ( Peng & Xie, 1995) and C. wulingoides ( Peng & Xie, 1995) by epigynal border almost two times longer than copulatory duct, with a depression medially [see Peng and Xie (1995: figs 40–43, 45–47)]. However, this species can be distinguished by the copulatory duct folded in right angle [vs. copulatory duct intertwined in C. wulingensis and C. wulingoides , see Peng and Xie (1995: figs 40–43, 45–47)]. For diagnosis of the male see Peng and Xie (1995).

Redescription. Female (holotype): Measurements see Song and Chai (1992).

Coloration ( Figs 6A, B ): Carapace dark brown to brown, cephalic dark brown, thoracic brown, black rings around eyes. Clypeus brown with sparse hairs. Fovea longitudinal. Chelicerae brown, endites, labium and sternum yellow-brown. Legs yellow with black rings, covered with sparse setae. Opisthosoma almost oval, yellow-brown with black pattern, with dense hairs. Spinnerets yellow.

Epigyne ( Figs 5A, B , 7B ): Epigynal plate oval, epigynal border wide. Copulatory openings located medially, with length between copulatory openings almost three times of copulatory opening width. Copulatory ducts Lshaped, connecting with anterior part of ental sides of spermathecae. Spermathecae S-shaped, separated.

Male. See Peng and Xie (1995, as Habrocestoides szechwanensis ).

Distribution. China (Hubei, Sichuan).

Comments. The type material of Chinattus undulatus was examined. Based on the clear figures in Prószyński (1992: figs 25–27) and Peng and Xie (1995: figs 9–11), no difference between C. undulatus , C. szechwanensis and C. emeiensis could be observed. Thus, we consider C. szechwanensis and C. emeiensis as junior synonyms of C. undulatus .

Notes. The “Yahow” in the collection data of Habrocestoides szechwanensis was a misspelling of Yachow (Ya’an). In June 1923, Graham, D. C. travelled from Suifu (now Yibin), via Yachow (now Ya’an)-Lu Ting Chiao (now Luding Bridge)-Wa Si Keo (now Wasi Valley) to Tatsienlu (now Kangding) to collect specimens ( Graham 1924).
