A new distribution record of Eirenis walteri (Boettger, ۱۸۸۸) (Ophidia: Colubridae), In Yazd province, Central Iran

Eirenis is one of the genus of snakes of the Colubridae family in Iran, all of which are small in size and their maximum body length is ۹۰ cm. The snakes of this family are close to the snakes of the genus Dolicophis and Hierophis. This is because the snakes of these two species have large sizes. Therefore, these genera share a common ancestor, so it can be concluded that pygmy snakes evolved from larger snakes.One of the species of this family is Eirenis walteri Rajabizadeh et al., ۲۰۱۴, the specimen was collected by field investigation and after identification, it was included in the snake fauna list of Yazd province for the first time. According to the Specimen and report in this research during June ۲۰۱۹, this species of snake was included in the checklist of snakes in Yazd province.Considering that the distribution of the genus Eirenis in Iran is associated with a great challenge, therefore new reports of the distribution of its species can provide an accurate map of the distribution of the species of this genus.Eirenis walteri is distributed throughout eastern Iran, and in this study, the first distribution record of Eirenis walteri in Bafaq mountain protected area, Qatrum village (Bafaq city), Yazd province, Iran is presented. Therefore, we can prepare a distribution map of Eirenis walteri with data collected by direct observation. Examining Eirenis walteri populations and their distribution range helps us to distinguish between them. Now we are sure of the wide distribution of this taxon in the central and eastern regions of Iran.​
