= Calyptostylis Arènes , Notul. Syst. (Paris) 12: 131. 1946. Type species: Calyptostylis humbertii Arènes (= Rhynchophora phillipsonii W. R. Anderson ).

Type species.

Rhynchophora humbertii Arènes.

Notes.

Rhynchophora comprises only two currently accepted species (all threatened species; Suppl. material 1) of lianas endemic to the seasonally dry tropical forests of Madagascar, Africa ( POWO 2024). For an identification key for all species of Rhynchophora , see Anderson (2001 a). Despite Madagasikaria causing the non-monophyly of Rhynchophora (Fig. 1 ), the bootstrap support value for this clade is below 60 %. Therefore, we have chosen to retain both genera as independent until further phylogenetic evidence sheds some light on the matter.

Figures

Figure 1. Molecular phylogenetic tree recovered by the ML of the reduced alignment for matK, ndhF, rbcL, and PHYC presented by Davis and Anderson (2010) with the taxonomic sampling reduced to one or three terminals according to the accepted genera in the present study. Left tree shows branch lengths recovered. Right tree shows the names of families, subfamilies, and tribes coloured according to the current classification recognised in this study. Bootstrap support values from the ML presented on the nodes. Black circles represent homoplasies, and red circles represent synapomorphies / autapomorphies recovered for each lineage. Numbers above circles represent character numbers from Suppl. material 2, while the numbers below the circles represent character states from the same file.
