|Comment||Specimens of this species have previously been assigned to C. annulatus.|
Diagnosis. The new species differs from most of Asia’s 115 Cyrtodactylus species by the same suite of character states that has facilitated the recognition and distinction of C. annulatus: (1) small body size; (2) light gray body, with dark transverse bands; (3) presence of a weak precloacal groove; (4) absence of enlarged femoral scales and pores; (5) moderately spinose tuberculation; (6) presence of forelimb tuberculation; (7) and absence of enlarged, median subcaudal scales (Taylor 1922; Brown & Alcala 1978; Manthey & Grossman 1997; Grismer 2005; Welton et al. 2009). Because the new species differs from non-Philippine congeners by characters that have distinguished C. annulatus (and have never been challenged; Taylor 1922a; Brown & Alcala 1978), we do not provide exhaustive comparisons to all those species (see Welton et al. 2009). Instead we focus on the comparisons relevant for the recognition of the new species: the closely related taxa within the C. annulatus complex and other Cyrtodactylus endemic to the Philippines. Cyrtodactylus jambangan differs from all other species of Philippine Cyrtodactylus (i.e., C. agusanensis, C. philippinicus, C. redimiculus, and C. tautbatorum; Table 2) by the following combination of characters: (1) small body size (2) dorsum darkly marbled lavender and brown or brown with indistinct wavy lavender blotches; (3) presence of bright yellow superciliaries, canthal stripe, and dorsal tubercles; (4) low dorsal scale counts (as measured by midbody dorsal and paravertebral scales; Table 2); (5) moderate numbers of midbody dorsal tubercle rows (Table 2); (6) absence of femoral pores in both sexes; (7) presence of precloacal pores in males and similarly enlarged, dimpled, scales in females, arranged in an inverted “V”-shaped configuration; (8) moderately depressed precloacal groove; (9) scales anterior to precloacal region undifferentiated; (10) lamellae under Finger III 17–22; (11) lamellae under Toe IV 20–24 (12) supralabials to beneath eye 8–11; (13) infralabials to beneath the eye 6–8; (14) absence of stripes connecting the lateral margins of transverse bands on trunk; and (15) midbody ventral scales 48–63. Comparisons with additional Southeast Asian species are provided in Table 3 in WELTON et al. 2010.
|Etymology||The specific epithet is derived from the term Jambangan—the ancient name for the Zamboanga City area. Sulu and Zamboanga folklore suggest that the name was bestowed upon the Zamboanga City area by the immigrant Subanons (“People of the River”) who arrived in western Mindanao and the Sulu archipelago in approximately 1200 A.D., after traveling by boat through the Sulu Archipelago, from what is now Indonesia. Jambangan means “The Land of Flowers,” a name presumably used in reference to the natural beauty of the area surrounding Zamboanga City.|
