A look at the Family Agamidae


Boulenger's Tree Agama, Sumatran Tree Dragon


Attractive arboreal agamids similar to Bronchocela, Calotes and Pseudocalotes [Manthey & Schuster]. These seem to be quite rare in the terrarium hobby, although German and Dutch breeders may have done some work with them. See Manthey & Schuster for husbandry details: they suggest a heavily-planted cloud-forest terrarium.

De Rooij gives the characteristics of the genus as follows: body compressed, covered with equal or slightly unequal scales; males have gular sac; dorsal scales slightly unequal; slight dorsal crest; no fold across throat; no fold in front of shoulder; tympanum distinct; no preanal or femoral pores.

First described in 2017: see Reptile Database entry.

D. boulengeri 

Boulenger's Tree Agama 

Indonesia (Sumatra) 

SVL 6½-7cm; TL up to 23 cm

Scalation details: nostril in an oval scale, separated from the rostral; rostral small; supranasal smooth; 8-10 supralabials; 9-10 sublabials; short spine behind supraciliary edge; 3-4 enlarged keeled scales on temples; 2 white tubercular scales below angle of mouth and below ear; large keeled scales in supraocular region; gular sac rather small, covered in feebly keeled scales; nuchal crest consists of 4-7 erect scales, longer than those of dorsal crest, which is composed of 13-14 scales and separated from nuchal crest; each scale of both crests separated from the next by 2 scales; dorsal crest extends to tail base. Dorsal scalation: dorsal scales feebly keeled, as large as ventrals, which are strongly keeled; laterals much smaller, almost smooth, in longitudinal rows; 68-75 in a row. Tail: compressed, covered at base with strongly keeled scales. Other: head quadrangular with sharp canthus rostralis; snout 1½-2 times as long as diameter of eye; tympanum smaller than eye; body laterally flattened; limbs long, covered with keeled scales; 4th toe somewhat longer than 3rd; digits with two ventral keels. Coloration: bluish-green above, with dark transverse bands on back, tail and limbs; yellow stripe on side of neck, bordering blackish oval spot; dark lines on flanks; lower parts pinkish, spotted with brown; Manthey & Schuster mention that the male usually has a bright green back with dark netting on the sides, and that the green back can take on a brown hue quite quickly, in which case the shoulder patch then appears lighter; iris is bright greenish-blue in males and brown in females. Reproduction: no details available apart from 4 eggs being recorded from a female [Manthey and Schuster]. [SOURCE: de Rooij, Manthey & Schuster]
