|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Common Names||Yathe Pyan cave bent-toed gecko|
|Synonym||Cyrtodactylus yathepyanensis GRISMER, WOOD JR, THURA, ZIN, QUAH, MURDOCH, GRISMER, LIN, KYAW & LWIN 2017: 74|
|Distribution||Myanmar (Hpa-an District, Kayin State)|
Type locality: Yathe Pyan Cave 9 km south-west of Hpa-an, Hpa-an District, Kayin State, Myanmar (N16°50.114, E97°34.243; 22 m in elevation).
|Types||Holotype: LSUHC 12823, Adult male, collected on 4 October 2016 at 1800 h by Evan S. H. Quah, Matthew L. Murdoch, L. Lee Grismer, Marta S. Grismer, Myint Kyaw Thura, Perry L. Wood, Jr., Thaw Zin and Htet Kyaw. Paratypes: Adult females BYU 52228–29 and LSUHC 12822 bear the same collection data as the holotype.|
|Diagnosis||Diagnosis: Cyrtodactylus yathepyanensis sp. nov. differs from all congeners by having the unique combination of nine or ten supralabials; eight or nine infralabials; 18 or 19 longitudinal rows of body tubercles; 31 or 32 paravertebral tubercles; 30–32 ventral scales; relatively long digits with eight or nine expanded subdigital lamellae proximal to the digital inflection on the fourth toe, 12–14 unmodified, distal, subdigital lamellae, 20–23 total subdigital lamellae; raised, moderately to strongly keeled, dorsal body tubercles extending beyond base of tail; enlarged femoral and precloacal scales continuous; 25–34 enlarged femoral scales, proximal scales one-half to one-third the size of distal scales; 17 femoral pores in males; 10–13 enlarged precloacal scales; six precloacal pores in males; three rows of enlarged post-precloacal scales; medial subcaudal scales three times as wide as long extending onto lateral surface of tail; top of head bearing diffuse dark mottling, no yellow reticulum; nuchal loop not divided medially, lacking an anterior, azygous notch, posterior border sinuous to jagged; 4–6 dark, jagged, dorsal bands lacking paravertebral elements, same width as interspaces, lacking lightened centres, edged with light tubercles; dark markings and lacking light tubercles in dorsal interspaces; ventrolateral folds whitish; anterodorsal margins of thighs and brachia darkly pigmented; 13 light caudal bands bearing dark markings, not encircling tail; 13 dark caudal bands wider than light caudal bands; and mature, regenerated tail not spotted.|
Comparisons: Cyrtodactylus yathepyanensis sp. nov. is part of the yathepyanensis group. The PCA and DAPC analyses indicate that the species of this group are completely separate in morphospace and that the first two principal components account for 54% of the total variation (Fig. 12; Fig. S5) and load most heavily for numbers of paravertebral tubercles and ventral scales (Table S4). Cyrtodactylus yathepyanensis sp. nov. is well-differentiated from C. linnoensis sp. nov. and C. sadanensis sp. nov. by having varying combinations of statistically different mean values of supralabial and infralabial scales, paravertebral tubercles, unmodified and total fourth toe lamellae, ventral scales, enlarged femoral scales, and longitudinal rows of body tubercles and precloacal pores (Table 4). It differs further from C. sadanensis sp. nov. and some C. linnoensis sp. nov. in having continuous vs. discontinuous enlarged femoral and precloacal scales and pigmented vs. unpigmented thighs and brachia, and from C. sadanensis sp. nov. in having a smaller maximum SVL (72.8 mm vs. 78.0 mm; Table 8). Morphological and colour pattern differences from other species in the Indo-Chinese clade are listed in Table 8. Genetic distances among the species of this group range from 11.0 to 12.7%.
|Etymology||The specific epithet, yathepyanensis (pronounced ya-thay-pee-an-ensis), is a noun in apposition in reference to the type locality of Yathe Pyan Cave.|
