Can you confirm these amateur observations of Cyrtodactylus ayeyarwadyensis?
|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Synonym||Cyrtodactylus ayeyarwadyensis BAUER 2003|
|Distribution||Myanmar (Burma: Rakhine), Bangladesh|
Type locality: Khoko Gwe Creek, Rakhine Yoma Elephant Range, Gwa Township, Rakhine State, Myanmar (17°43’48.3’’N, 94°39’02.7’’E)
|Types||Holotype: CAS 226154|
|Diagnosis||DIAGNOSIS.— Cyrtodactylus ayeyarwadyensis may be distinguished from all congeners on the basis of its possession of short digits, a single series of precloacal pores (10–28) in males only, absence of femoral pores and precloacal groove, 22–24 longitudinal rows of dorsal tubercles; 32–37 ventral scales between ventrolateral folds, subcaudal scalation without enlarged midventral plates, and dorsal pattern of 9–11 (usually 10) transverse rows of rectangular brown blotches from occiput to sacrum, usually bordered posteriorly by white punctations or a narrow white band. Among other species from Myanmar it is most similar to C. khasiensis and a new species from Chin State, described below. All are similar in size and bear a series of dark dorsal markings. Cyrtodactylus ayeyarwadyensis differs from C. khasiensis, however, in having (in some specimens) a greater number of precloacal pores (maximum 28 vs 14), rectangular dorsal blotches (vs a more variegated pattern of alternating irregular light and dark bands, or even stripes; Hora 1926), white dorsal punctuations or lines bordering dorsal blotches (in most cases), and narrow white tail bands (vs subequal light and dark bands in C. khasiensis). It differs from the other new species in both color pattern (rectangular dark markings and white punctuations vs narrow transverse bands) and precloacal pore configuration (strongly angled and recessed into a shallow groove in the Chin State species) [after BAUER 2003].|
|Comment||DEFINITION.— A moderate sized Cyrtodactylus, snout-vent length to 78 mm; body relatively slender, limbs moderately long and digits relatively short; one pair of enlarged postmental scales, in broad contact with one another behind mental; 22–24 rows of keeled, oblong dorsal tubercles; 32–37 ventral scales between ventrolateral folds; no precloacal groove, 10–28 precloacal pores in a single series (or with scattered gaps of one poreless scale) in males only. Six widened subdigital lamellae beneath basal phalanx of 4th toe of pes, 10 narrow lamellae beneath more distal phalanges of same toe (in holotype). Subcaudal scalation without enlarged midventral plates. Dorsal pattern of 9–11 (usually 10) transverse rows of rectangular brown blotches from occiput to sacrum. Posterior border of each row usually marked by white punctations or a narrow white band; tail with alternating brown and white bands.|
|Etymology||Named after the Ayeyarwady (Irrawaddy) River which runs through Myanmar. The range of the species includes parts of the Ayeyarwady delta.|
