|Distribution||Soviet Union (Caucasus), S Armenia, SE/SW Azerbaijan, CE Turkey, W Iran, NE Iraq|
condoni: Iran (southern Zagros mountains and the adjacent area of the western Zagros foothills, in the south to low elevated mountain sides adjacent to Persian Gulf, and eastwards to around Kerman and Bam cities in Kerman province); Type locality: Around Shiraz, Fars province, Iran.
kumerloevei (now invalid): Akdamar Island in Lake Van.
punctatolineatus: Central-eastern Turkey, central and southern Armenia, southern Azerbaijan, Nakhichevan, and northern and western Iran in the northern Zagros and Azarbaijan mountains and through the Alborz Mountains up to northern Khorasan and adjacent mountains of central Iran; Type locality: Armenia
|Types||Holotype: SMF 19288 according to Mertens (1967).|
Holotype: BMNH 19188.8.131.52 [condoni]
Holotype: ZFMK 5990 [Eirenis punctatolineatus kumerloevei]
|Diagnosis||Diagnosis: The nominate subspecies is characterised by a combination of morphometric, meristic and color pattern characters, especially by the num- ber of subcaudal scales, 63-77 (X = 72.09) in males and 61-68 (X = 64.67) in females and the ratio of tail length on total length, 21.86- 26.40 (X = 24.66) in males and 20.77-23.17 (X = 21.79). Detailed morphological characteristics of Eirenis punctatolineatus punctato- lineatus have been presented in tables 2, 6, and 7. The color pattern of the nominate subspecies consists of a light brown dorsal ground color with anterior dorsal dark crossbars, interrupted on dorsal midline, which reduce posteriorly to dark spots and then progressively change to longitudinal continuous or interrupted dorsal parallel lines at 1/2 to 2/3 of total length. This typical pattern changes a little in some specimens and the anterior dorsal crossbars are replaced by square-shaped dark spots. Some adults are com- pletely patternless. Only in some adult speci- mens of Akdamar Island in Lake Van, the dorsal ground color has changed into dark gray or black (the former melanistic subspecies kumer- loevei Eiselt, 1970); and these specimens don’t display any visible dorsal pattern.|
Diagnosis (condoni): Eirenis punctatolineatus condoni (Boulenger, 1920) can be distinguished from Eirenis punctatolineatus punctatolineatus (Boettger, 1892) by a combination of morphometric, meristic and color pattern characters. Eirenis punctatolinea- tus condoni has a higher mean value in the num- ber of subcaudal scales than the nominate sub- species, 72-93 (X = 83.46) compared to 63-77 (X = 72.09) in males and 72-78 (X = 77.44) compared to 61-68 (X = 64.67) in females. Also E. p. condoni has a higher percent ratio of tail length to total length than the nom- inate subspecies, 26.65-30.70 (X = 28.60 ± 0.29) compare to 21.86-26.40 (X = 24.66 ± 0.40) in males and 23.53-27.73 (X = 25.46 ± 0.43) compared to 20.77-23.17 (X = 21.79 ± 0.31) in females. As well, E. p. condoni has a lower percentage of the ratio of head length to total length than the nominate subspecies, 2.47-4.39 (X = 3.68 ± 0.13) compared to 3.36- 5.43 (X = 4.13 ± 0.17) in males and 2.87- 4.11 (X = 3.28 ± 0.12) compared to 3.44-4.26 (3.79 ± 0.09) in females. Contrary to the nomi- nate subspecies, the dark pattern of the posterior parts of the body and of the tail is missing.
|Comment||Synonymy partly after KHALIKOV & ANANJEVA (pers. comm.). FRANZEN & SIGG (1989) synonymized Eirenis punctatolineatus kumerloevei with Eirenis punctatolineatus. Zamenis bornmüllerorum Werner, 1903 was based on the examination of one specimen from “Elburs (= Al- borz) mountain” “am Keredscli (supposedly Karaj)-Ufer”, Iran, at the elevation of 2100 m. Nikolsky (1909) described Contia schelkovnikovi based on the examination of one specimen from a dry slope near Dzhi village of Lenkoran region (Azerbajdzhan Republic). Contia condoni Boulenger, 1920 was based on a couple of specimens collected from Shiraz (center of Fars province, Iran). Eirenis iranica Schmidt, 1939 was described based on a single adult male collected in 1934 from Tirak Mart mountain (now: Bibi Shahrbanu mountain) near Rayy (now: Rey), south of Tehran, Iran. Eirenis punctatolineatus kumerloevei Eiselt, 1970 was based on a single specimen from Akdamar Island in Van Lake, Turkey. It was distinguished from the nominal subspecies by a black dorsal coloration with scattered light spots. Franzen and Sigg (1989) erected questions about the validity of this subspecies, as only 11 of 22 specimens examined by them from Akdamar Island, showed the black dorsal color.|
