Remarks

The specimens from New Caledonia form two distinct and supported molecular subclades ( Fig. 2 ). One of them includes only specimens from south of New Caledonia (mostly around Île des Pins), while the second one combines specimens from southern and northern New Caledonia as well as from the Coral Sea. Each subclade includes one specimen from Papua New Guinea (see above). Morphologically, the specimens from south of New Caledonia around Île des Pins are very similar, although they belong to different subclades. Conversely, specimens from the Coral Sea and north of New Caledonia are morphologically very variable, despite belonging to the same subclade.

Figures

Fig. 2. Molecular phylogeny of Amalda hilgendorfi (von Martens, 1897) produced by a Bayesian analysis of the Cox1 gene dataset. Outgroups and other species of Amalda have been removed from the tree. Only posterior probabilities ± 90% are shown. The unit for the scale is “substitutions/site”. The geographical distribution and morphological morphs are coded for each specimen: Phil =Philippines; Sol =Solomon Islands; PNG= Papua New Guinea; sNC = South New Caledonia; nNC = North New Caledonia; CS=Coral Sea. Numbers in parentheses at the tips of the tree link the MNHN IM voucher number to the corresponding photo on the right.
