Lizards of the genus Draco are commonly recognized as Southeast Asian Flying Lizards. This moderate-sized radiation of arboreal lizards is capable of long distance gliding using wing-like patagial membranes supported by elongate thoracic ribs (McGuire and Alcala, 2000). In the Philippines there exist an endemic and species-rich assemblage of species in this genus (McGuire and Alcala, 2000). One of these species is Draco guentheri, recognized to occur in the Mindanao and Sulu faunal regions (Mindanao PAIC, Sulu Archipelago) in the southern Philippines. The ventral surface of this species patagium is salmon or brick red, generally with only one dark spot near the outer margin in males (Taylor, 1922; McGuire and Alcala, 2000), versus light yellow with several to many small dark spots in females (McGuire and Alcala, 2000). In males of this species, the dewlap is triangular, and is bright purple or reddish with a bright yellow tip (Taylor, 1922; Gaulke, 1993; McGuire and Alcala, 2000). Several species in the Philippines are recognized to have widespread distributions (D. quadrasi, D. spilopterus); however, recent work indicates these species may actually be complexes of multiple, morphological similar species (McGuire and Alcala, 2000; McGuire and Heang, 2001).
Draco guentheri can be distinguished from all other species of Draco in the Philippines by the following combination of characteristics: (1) moderately large size; (2) nostrils oriented laterally; (3) enlarged, thornlike supraciliary scale present; (4) dorsal scales variable in size, often with strong keeling; (5) presence of large, unscaled tympana; (6) mode of six ribs supporting patagium; (7) lacrimal bone absent; (8) large black postrictal ocellus surrounding an enlarged white tubercle absent; (9) dorsal patagial coloration of males dark green with numerous spots of bluish or yellow-green, outer margin salmon (Taylor, 1922); (10) dorsal patagial coloration of females black, with slight gray wash, enclosing bright reddish to orange spots (Taylor, 1922); (11) in males, ventral surface of patagium salmon or brick red, usually with only one dark spot near outer margin (Taylor, 1922); (12) in females, ventral surface of patagium light yellow, with variable numbers of small dark spots; (13) males with triangular dewlap, bright purple or reddish with bright yellow tip (Taylor, 1922; Gaulke, 1993); (14) malachite green dorsal body coloration in males; females metallic, iridescent gray (Taylor, 1922); (15) males with orbital region heavily suffused with dark pigment (information taken from McGuire and Alcala, 2000).
Draco guentheri is known from the islands of Basilan, Bongao, Jolo, Mindanao, Sanga Sanga, Siasi, and Siminul (Taylor, 1918, 1922; Gaulke, 1993, 1995). The species is known primarily from the Zamboanga region of Mindanao and from the Sulu Archipelago.
Draco guentheri has been observed in sympatry with D. bimaculatus, D. cyanopterus, and D. mindanensis, but is often considered uncommon relative to D. bimaculatus and D. cyanopterus (McGuire and Alcala, 2000). At San Roque and Cabala, widely spaced localities in the eastern half of Mindanao characterized by open coconut groves, D. guentheri was not found (McGuire and Alcala, 2000). Taylor (1918, 1922) indicated that D. guentheri is the common species of the Sulu Archipelago and because it has been collected within the confines of the city of Zamboanga, it seems likely that the species does occur in open habitats such as coconut groves in the western portion of its range (text take from McGuire and Alcala, 2000).
Draco guentheri is recognized to occur in the Mindanao Pleistocene Aggregate Island Complex.
Little is known about the natural history of Draco guentheri. McGuire and Alcala (2000) found this species in secondary-growth forest and on coconut trees adjacent to forest near the Malagos Eagle Station, Mindanao Island.
Maximum recorded SVL up to 97 mm
Draco guentheri, commonly known as Günther's flying lizard[2] is a species of agamid "flying dragon" endemic to the Philippines.
D. guentheri is found on the islands of Basilan, Bongao, Jolo, Mindanao, Sanga-Sanga, Siasi, and Simunul.
The specific name, guentheri, is in honor of German-British zoologist Albert Gunther.[1][2]
This species was originally described in 1885 by the Belgian-British zoologist George Albert Boulenger, who named it Draco guentheri.
This species is also notable for having been collected by the Philippine national hero Jose Rizal during his exile in Dapitan, Mindanao in 1893 and identified it as a new type of lizard in which he tentatively named, Draco dapitani. Rizal sent specimens to Europe, to the German zoologist Benno Wandolleck. In 1900 Wandolleck, thinking Rizal's specimens represented a new species, described it and named it Draco rizali, thereby creating a synonym. Rizal's specimens, subsequently, were destroyed during the bombing of Dresden in World War II.[3]
In 1936 Hennig considered this lizard to be part of what he called a subspecies, Draco volans reticulatus. In 1993 Gaulke raised it to full species status. And most recently, in 2000, McGuire and Alcala once again recognized Boulenger's original Draco guentheri as a valid species.
