Type. Male holotype from Huangyuan County, Qinghai Province, China, 15.IX.1984, Z.S. Li leg., deposited in IZCAS .

Etymology. The specific name is a patronym in honor of Dr Christo Deltshev.

Diagnosis. Males of E. deltshevi can be distinguished by the form of the specialized setae situated distally on the retrolateral ledge of the palpal tibia, as detailed above, and by the distally more sharply angled embolus ( Forster et al. 1987: fig. 79). Females have the inner pair of spermathecae shorter, less robust, and distally less sclerotized than in E. davidi .

Male. Described by Forster et al. (1987: 23), as E. davidi .

Female. Described by Forster et al. (1987: 23), as E. davidi .
