This monotypic genus formerly contained five species, of which four were recently (2019) reassigned to the genus Pelturagonia.
Boulenger (apparently citing from Hubrecht) gives the characteristics of the genus as follows: tympanum hidden; no femoral pores; back and sides covered with small smooth scales, intermixed with larger keeled ones, and with very large multicarinate conical tubercles. No dorsal crest. A row of longer crest-scales above the eye. Upper surface of head covered with conical tubercles.
I have not seen this species offered in the UK, and the name does not seem to crop up in herpetological circles in Germany or the US either. Manthey and Schuster cover the genus and P. nigrilabris (now Pelturagonia nigrilabris) in their book and note that they are not particularly difficult captives, not least because they are small as agamids go - P. nigrilabris is no more than 9cm in total length. They would appear to be at least somewhat arboreal.
Hubrecht in 1881 summarised the differences between Phoxophrys and Japalura as follows (taken from Inger 1960):
Phoxophrys |
Japalura |
Lacks dorsal crest |
Dorsal crest present |
Few large tubercular scales laterally |
Enlarged scales are simply unicarinate |
Supraciliaries juxtaposed or very slightly imbricate |
Each supraciliary overlaps its successor by at least one third |
Head relatively short and deep |
Head relatively long and flat |
Lacks hair-like sense organs on cephalic scales |
Hair-like sense organs present on cephalic scales |
Rostral if distinguishable is at most twice as wide as high and only occupies centre of end of snout |
Rostral 3-4 times as wide as high and occupies entire end of snout |
Tail of male is markedly swollen basally, flattened above and furnished with dorsolateral keels formed by enlarged angular scales |
Tail of male is compressed, oval in cross section and not flattened above; usually a low middorsal caudal crest is formed by median row of enlarged keeled scales (only J. flaviceps deviates from this rule) |

Scalation details: nasal contacts 1st and 2nd supralabials; 2 continuous rows of infraorbitals; supraciliary scales raised into crest; several strongly compressed supraoculars; gular scales sharply keeled, mucronate; nuchal crest absent; vertebral scale row posteriorly lacks continuous series of enlarged scales; lateral caudal scales keeled; 4 rows of keeled subcaudals near base. Reproduction: no details available. |
