Common Names 
SynonymCyrtodactylus tautbatorum WELTON, SILER, DIESMOS & BROWN 2009 
DistributionPhilippines (Palawan)

Type locality: on the roots of a tree overhanging a stream in Philippines, Palawan Island, Palawan Province, municipality of Brooke’s Point, Barangay Mainit, Mainit Falls (09° 50’ 204’’ N, 118° 38’ 497’’ E; 106 m elevation).  
TypesHolotype: PNM 9507 (field no. RMB7724), an adult male, hemipenes everted (a portion of the liver preserved separately in 95% ethanol, deposited in tissue collection at KU), collected on 24 March 2007 (19:00–22:00h) by RMB and Jason Fernandez. 
DiagnosisDiagnosis. Cyrtodactylus tautbatorum is readily diagnosed from its phenotypically most similar Philippine congener, C. annulatus by the following combination of characters: (1) 4 or 5 ‘‘bow-tie’’ shaped (vs. invariably 3 ‘‘barbell’’ shaped; Fig. 4, 5) transverse body bands between limb insertions; (2) ventrolateral tubercle row highly protuberant (vs. nonprotuberant or absent): (3) contact between the first infralabial and three (vs. two) enlarged postmentals; (4) internasal in contact with supranasals; (5) dorsal trunk tubercles convex (vs. conical or pointed sharply); and (6) smaller body size (Table 1). The new species is much smaller than Cyrtodactylus agusanensis, and further differs from this species by having of a precloacal groove, the internasal in contact with supranasals, and fewer subdigital lamellae, precloacal pores, midbody tubercle rows, and midbody dorsal scale rows; C. tautbatorum also lacks a series of femoral pore-bearing scales, present in C. agusanensis. Cyrtodactylus tautbatorum is smaller than C. philippinicus, from which it can further be distinguished by having the internasal in contact with supranasals, fewer third finger subdigital lamellae, precloacal pores, midbody tubercle rows (Table 1), and ‘‘bow tie’’ shaped (vs. ‘‘barbell’’ shaped) transverse body bands. The new species is also smaller than its only sympatric congener, C. redimiculus, and further differs from this species by having ‘‘bow-tie’’ shaped (vs. wavy) transverse body bands, internasal in contact with supranasals, a precloacal groove, more paravertebral tubercles, fewer third finger subdigital lamellae, and fewer midbody dorsal scale rows. C. tautbatorum is also distinguished by the absence of enlarged femoral scales and pores, and the absence of a reticulate (whiteon- black) head color pattern. These and other features distinguishing Philippine congeners are summarized in Table 1, whereas characters distinguishing the new species from morphologically similar non-Philippine species are summarized in Table 2 in WELTON et al. 2009). 
CommentSpecimens of this species have previously been assigned to C. annulatus. 
EtymologyThe specific epithet tautbatorum is chosen in recognition of the Tau’t-Bato peoples of the Singnapan Basin volcano crater, western Mt. Mantalingajan, southern Palawan Island. The Tau’t-Bato (‘‘People of the Rock’’) possess a highly distinct cultural identity that celebrates fierce protection of their natural resources, respect for the forest, and appreciation of forest animals.
