TAHANANPUNO SUBGEN. NOV.

Type species

Cornufer guentheri Boulenger, 1882 .

Diagnosis

Members of this tree canopy specialist clade or Philippine rain frogs, subgenus Tahananpuno , differ from other all species of Platymantis (except Pl. banahao , Pl. cornutus , and Pl. insulatus , see below) by having (1) widely expanded terminal discs of fingers and toes (vs. non- or minimally expanded in terrestrial species of Tagomukus and Lupacolus ); (2) prominent, rounded to pointed subarticular tubercles (vs. flattened on ventral surfaces in cloud frog species of the subgenus Tirahanulap ); (3) pulsed advertisement calls (vs. tonal, constant frequency calls of cloud frogs, subgenus Tirahanulap ; vibrational, stridulated, or complex multisyllable calls of species of terrestrial frogs of the subgenera Tagomukus and Lupacolus ); and (4) understory ( Pl. guentheri ), limestone ( Pl. bayani ), cliff-edge ( Pl. diesmosi ), or canopy vegetation microhabitat preferences (all other Tahananpuno species). Although widely expanded terminal discs of fingers and toes appear to be a synapomorphy for this clade, they have evolved independently and diagnose a small subclade of variable Philippine forest frogs only, subgenus Lahatnanguri ( Pl. banahao , Pl. cornutus , and Pl. insulatus ). We are unaware of any unique characters that distinguish species of this new subgenus from other species of Platymantis . Nevertheless, our phylogenetic analyses provide strong support for this clade ( Fig. 2, Clade Q).

Phylogenetic definition

Tahananpuno (NCN) is a maximum crown-clade name referring to the crown clade ( Fig. 2, Clade Q) originating with the most recent common ancestor of Platymantis (Tahananpuno) guentheri and all extant species that share a more recent common ancestor with Pl. guentheri than with Pl. corrugatus , Pl. dorsalis , Pl. hazelae , or Pl. levigatus .

Content

Platymantis bayani , Pl. diesmosi, Pl. guentheri , Pl. luzonensis , Pl. negrosensis , and Pl. rabori ( Table 3).

Comment

The subgenus Tahananpuno corresponds to the readily distinguished Pl. guentheri group as defined by Brown et al. (1997a, b) and Alcala & Brown (1999). Interestingly, and in contrast to expectations based on morphology and understory/canopy microhabitat preferences ( Brown et al., 1997a), Pl. banahao , Pl. cornutus , and Pl. insulatus are not part of this clade (or of the former Pl. guentheri group; Brown et al., 1997a, b; Alcala & Brown, 1999), but rather fall in Clade O ( Lahatnanguri ). We are aware of at least four additional unrecognized species in this clade (species 6, 7, 8, and 9; Fig. 2).

Etymology

Tahananpuno is a masculine noun, derived from the Tagalog verb tahanan meaning ‘to dwell upon’, or ‘to occupy’ and noun puno, ‘tree’, in reference to the prevailing microhabitat preference of species in this clade: understory and canopy treefrogs. The name is masculine in gender. Suggested common name: Philippine rain frogs.
