|Distribution||E Iran, Pakistan|
Type locality: Bahu Kalat; Zamran; Nlhmg River; Askan, near Bampusht, Iran; and Ras Malan; Mand; Pakistan; restricted to Bahu Kalat and Askan, Baluchistan by Smith 1935: 61.
|Types||Syntypes: BMNH 220.127.116.11-54 (= BMNH 1918.104.22.168-35), MCZ 7136; ZMB 10234; ZSI 3487, 3501, 6811-6812; Bauer & Günther 1991 “regard the BMNH type for which Boulenger 1885 provided measurements as the lectotype.” (withouth saying which specimen this was); see also Das et al. 1998).|
|Diagnosis||Definition (genus): Limbs slender; digits slender, clawed, cylindrical at base, with smooth transverse lamellae beneath, angularly bent, the distal phalanges slightly compressed, forming an angle with the basal portion ofthe digits, the claw between two enlarged scales; no enlarged plate-like postmental shields; dorsal scales small granules intermixed with larger tubercles; tail cylindrical, slender, diminishing suddenly in size after the basal portion (Fig. J in key), not longer than head and body; basal caudal autotomy only; pupil vertical (Anderson 1999: 129).|
Diagnosis: (cruralis) Dorsal tubercles sharply keeled; large tubercles presented top of the thigh; long forelimb; number of ventral scales lower than 32 a cross midbody; head large; number of scales between tubercles 4; color dark brown (from HOSSEINIAN-YOUSEFKHANI et al. 2017)
In the three syntypes of Agamura cruralis Blanford in the British Museum, the rostral is only partially divided; there are five dorsal crossbars in those in which the pattern can still be seen; tubercles are lacking on the hind limbs; the subcaudals are not divided into two longitudinal rows except at the flattened tip. I do not find any clear indication of preanal pores in these specimens. A specimen from Cheh Mossullum (FMNH 170934) agrees with Blanford's description of A. cruralis in having the rostral only partially divided and lacking tubercles on the limbs. It is a male with two preanal pores and I do not find other consistent differences between this and other specimens.
Szczerbak and Golubev (1986:211; 1996:206) stated that in Iranian Baluchistan and to the north up to the Sistan basin and the Dasht-e Lut, enlarged chin shields appear in this species. They noted that these specimens had some divergence in other characters as well, and while a shortage ofspecimens did not permit final taxonomic resolution, they suggested that recognition of a subspecies, A. persica cruralis, was justified (Anderson 1999: 132).
|Comment||Type species: Agamura cruralis BLANFORD 1874 is the type species of the genus Agamura BLANFORD 1874.|
Synonymy: Smith (1935) synonymized A. persica and A. cruralis. This was maintained by Anderson 1999. However, HOSSEINIAN-YOUSEFKHANI et al. 2017 resurrected A. cruralis based on morphology.
Distribution: HOSSEINIAN-YOUSEFKHANI et al. 2018 have a map with both persica and cruralis with the latter being restricted to eastern Iran and W Pakistan.
