During a her- petofaunal survey in November 2006, a single subadult specimen of T. steudneri was collected from Deh Kohneh in southwestern Fars. In November 2007 and May 2008, two specimens of H. flaviviridis were collected from Ghaleh Seied in western Fars, respectively. The collection locations of the two new records are well outside the known distribu- tion ranges of the two species in Iran. Keywords lizard, new record, distribution, Iranian Plateau, gecko The dwarf geckos of the genus Tropiocolotes Peters, ghanistan and Pakistan (Anderson, 1999; Rastegar-Pouyani 1880 are a group of tiny geckonids occurring in the Mid- et al., 2006, 2007). Steudner’s dwarf gecko, Tropio- dle East region (Anderson, 1999; Rastegar-Pouyani et al., colotes steudneri, has been reported to have a distribution 2006, 2007). The main characteristics of these small ranging from Ethiopia, Sudan, Algeria, Egypt, Jordan, lizards are described as follows: nocturnal habits; small Israel to Iran (Rastegar-Pouyani et al., 2006, 2007). size (snout-vent length, rarely exceeding 35 mm); slightly The leaf-toed geckos of the genus Hemidactylus Oken, angularly bent digits not dilated, not fringed, not webbed, 1817 are a group of geckonids occurring in Africa, not ornamented, and covered below with a single series southern Europe, southern Asia, Oceania and tropical of transverse lamellae; uniform, small, homogenous, im- America. It is now understood that this genus consists of bricate to subimbricate dorsal scales; vertical pupil; approximately 90 currently recognized species and has its presence of postanal sacs (Leviton et al., 1992; Anderson, main centre of speciation in Somalia and its adjoining 1999; Rastegar-Pouyani et al., 2006, 2007); usually ab- areas (Sindaco et al., 2007, 2009).

Hemidactylus is flaviviridis were collected on different walls of the house morphologically conservative in many features, such as and were relatively active during midday, but fully active skull structure and number of presacral vertebrae (usually at night. 26, a primitive trait in gekkonids). There is however con- siderable variation in a range of external features inclu- ding the following: body size; proportions of the head, body and limbs, and of the unregenerated tail which may be laterally expanded or swollen; number of internasal granules; size of dorsal scales and their degree of poste- rior imbrication; presence or absence of enlarged dorsal tubercles and, when they are present, their number, size, detailed shape, and extent on body head and limbs; num- ber and extent of femoral pores in males or their complete Figure 1 A subadult Tropiocolotes steudneri treated in this study absence; size of adhesive pads on digits and the number of expanded subdigital lamellae that constitute them ex- ternally (especially on toes 1 and 4), and whether or not the lamellae extend proximally onto the sole of the foot; presence or absence of the distal section of digit I of ma- nus and pes including the claw; presence or absence of webbing on the toes; presence or absence of enlarged tubercles on the tail and whether these are spinose; whether subcaudal scales are enlarged and laterally ex- panded or small; dorsal and ventral colouring and pattern (Carranza and Arnold, 2006; McMahan and Zug, 2007). Four species of Hemidactylus occur in Iran, that is, H. persicus, H. turcicus, H. flaviviridis and H. robustus (Rastegar-Pouyani et al., 2008).

In November 2006, during our field work on the her- petofauna of Fars Province, a single subadult specimen of T. steudneri (Figure 1) was collected from ‘Deh Kohneh’ (27°28′ N and 53°04′ E, at an elevation of 447 m), ap- proximately one km northeast from the Varavi, 25 km to the city of Lamerd, in southwestern portion of the Fars Province. It was found inactive in the afternoon hidden under a small stone in wet ground (after a rain) together with a juvenile scorpion and three individuals of a co- leopter on a hillside amongst sparse xerophytic vegeta- tion. In November 2007 and May 2008, two specimens of Figure 3 Location of Fars Province on the Iranian Plateau. The H. flaviviridis (Figure 2) were also collected in a house, blue circle and red quadrangular indicate the new localities for T.
