Etymology :

 

The generic name Hypsilurus comes from "upsilon-tail". Upsilon ("ϒ") is the Greek letter on which the English uppercase "Y" is based. The specific name, dilophus, is from the Greek for 'double crested'.

 

Description :

 

A large, short-tailed species with heterogeneous dorsal scalation and a discontinuous vertebral crest. There are several slightly enlarged scales below the tympanum, a row of enlarged submaxillaries and a serlies of large, lanceolate scales on the anterior edge of the gular pouch.

 

The species differs from H. boydii in that it lacks large conical scales below the tympanum; it differs from H. spinipes in that it has lanceolate scales on the nuchal and dorsal crests (rather than triangular); and it differs from all other species of Hypsilurus in that it has a heterogeneous (rather than homogeneous) dorsal scalation.

 

Distribution :

 

This species is found in New Guinea and the Moluccan islands, Indonesia. It is present across the entire island of New Guinea,

although it appears to have an upper elevation limit of 800 metres. It has been recorded on the Moluccan islands of Aru and Kei, Batanta and 

 

Salawati in West Papua Province, Numfoor and Yapen in Papua Province, Indonesian New Guinea and Fergusson island in Milne Bay Province, Papua New Guinea.[1][2] As this species appears to exhibit an association with rainforest or former rainforest, it is probably absent from the savannah of the Trans-Fly, and no records from this region are known.

Habitat and ecology :

 

Found in lowland and mid-montane primary and secondary rainforest. It is primarily found in the forest interior and regrowth areas, and will persist in areas of garden agriculture with some trees. It is an arboreal species whose prey includes insects and small fruits.[3]

 

Conservation :

 

Although lowland rainforest in Papua New Guinea is increasingly being cleared for logging and conversion to agriculture, this species is widespread across the island and can persist in some modified habitats, so it's unlikely to be in any imminent danger.

 

The species is occasionally traded in small numbers from Papua Province in Indonesian New Guinea.[4] It is not CITES-listed and is not legally protected in Indonesia, but the level of trade that has been observed appears unlikely to have a significant effect on wild populations.

Taxonomy :

 

Research is needed to clarify the taxonomy of what is more than likely a complex of species. Its closest relatives are H. boydii and H. spinipes.[1]

Geographic range :

 

L. spinipes is native to eastern Australian rainforests and rainforest margins from around Gosford in New South Wales to near Gympie in Queensland. It is also present in Barrington Tops National Park, New South Wales.

 

Description  :

 

The southern angle-headed dragon has a large and continuous nuchal crest with a moderately large vertebral crest. The angular brow is pronounced on both adults and juveniles. The snout to vent length is around 110 to 150 mm (4.3 to 5.9 in), additionally there is a long tail which takes the total length to 350 mm (14 in).

 

The colour varies from shades of brown, grey and green. Patterns where present consist of various irregular mottling, blotches and variegations.

 

Behaviour :

 

The southern angle-headed dragon is cryptic, slow moving and well camouflaged. Sometimes encountered basking in sunlight after rain. Often perching on buttresses, sapling stems or old stumps. They tend not to dash for cover, but slide discreetly out of view.

 

Diet :

 

The diet includes insects and other arthropods such as spiders and centipedes.

 

Reproduction :

 

Eggs are laid in shallow nests in rainforest clearings, including road edges and walking tracks. There is some evidence that they will occasionally lay communal nests. The eggs are vulnerable to predation, particularly by goannas.
