Due to their closer divergence, the New Zealand and Australian endemics (without Pseudothecadactylus) form a sister clade, while the New Caledonian diplodactylids show evidence of their more recent and rapid radiation in short branch lengths. Because the quick succession of genera can complicate phylogenetic reconstruction, it may remain difficult to produce well-supported intergeneric relationships for the eight New Caledonian diplodactylids in spite of a growing number of studies investigating them. New Zealand genera have proved somewhat easier to analyze. The group has correspondingly gone through several taxonomic revisions to reach the current order of genera proposed by Nielson et al. in 2011. Yet, a high amount of cryptic diversity remains unresolved, especially within Hoplodactylus. Australia genera such as Diplodactylus, Lucasium, Rhynchoedura and Strophurus are generally considered well-studied, with many of their intergeneric relationships strongly supported and resolved. The Pseudothecadactylus affinity to New Caledonian geckos has been informative and is under study, while Oedura are being increasingly examined. However, more work is still needed to understand the basal relationships and divergence of other “non-core” genera like Nebulifera, Amalosia, Hespeodura and Crenadactylus.Multiple studies in all three endemic clades of the Diplodactylidae have suggested and confirmed that high cryptic diversity exists at the species level. Because undescribed diversity can have serious implications for not only evolutionary and ecological understanding, but also for effective conservation of the family, this is an issue to be resolved within the Diplodactylidae phylogeny. Endemic Gondwanan lineages, a diversity of habitats, and the relative isolation of the three Australian regions have allowed for a significant speciation of diplodactylids. In 2009 an additional 16 Diplodactylus species within the Australian radiation were described, while evidence of deep divergence within Crenadactylus revised the single nominal species Crenadactylus ocellatus into 10 distinct lineages in 2010. Likewise 16 new species in New Zealand were recognized in 2011. In 2014 another seven genetically distinct and morphologically diagnosable taxa were described in Australia, and two years later four additional species were added to Oedura. In 2020 four new species were reported in New Caledonia. Just
