Myersiohyla View in CoL , new genus

TYPE SPECIES: Hyla inparquesi Ayarzagüena and Señaris (‘‘1993’’ [1994]).

DIAGNOSIS: This genus is diagnosed by 48 transformations in mitochondrial protein and ribosomal genes. See appendix 5 for complete list of these molecular synapomorphies. We are not aware of any morphological synapomorphy for this group.

ETYMOLOGY: Dedicated to Charles W. Myers in recognition of his contributions to herpetology, particularly to the herpetofauna of the Guayana Highlands. The name derives from Myersius (latinized Myers) 1 connecting ­ o 1 Hyla . The gender is feminine (Myers and Stothers, MS).

COMMENTS: This new genus includes the species of Hyla aromatica group and H. kanaima , a former member of the H. geographica group. Ayarzagüena and Señaris (‘‘1993’’ [1994]) included the presence of a strong odor in the definition of the Hyla aromatica group; this could be a possible synapomorphy of Myersiohyla . The presence of a strong odor has yet to be recorded in H. kanaima . It should be noted that the sample we included of H. inparquesi was not collected in the type locality, but in Cerro de la Neblina, ca. 300 km southward.

CONTENTS: Four species. Myersiohyla aro­ matica (Ayarzagüena and Señaris, ‘‘1993’’ [1994]), new comb.; Myersiohyla inparquesi (Ayarzagüena and Señaris, ‘‘1993’’ [1994]), new comb.; Myersiohyla loveridgei (Rivero, 1961) , new comb.; Myersiohyla kanaima (Goin and Wodley, 1961) , new comb.

DENDROPSOPHINI FITZINGER, 1843

Dendropsophi Fitzinger, 1843. Type genus: Dendropsophus Fitzinger, 1843 .

DIAGNOSIS: This tribe is diagnosed by 23 transformations in nuclear and mitochondrial protein and ribosomal genes. See appendix 5 for a complete list of these molecular synapomorphies. Apparent morphological synapomorphies of this tribe are the absence of lingual papillae in the larvae (known instances of reversal in Lysapsus and Pseudis ) and the absence of nuptial excrescences (with instances of homoplasy in some species of Sphaenorhynchus and several Cophomantini ).

COMMENTS: This tribe contains the genera Dendropsophus , Lysapsus , Pseudis , Scarthyla , Scinax , Sphaenorhynchus , and Xenohyla . The absence of lingual papillae in the larvae is the condition reported in all species of Dendropsophus , Scarthyla , and Scinax , whose larvae have been studied (Wassersug, 1980; Duellman and de Sa´, 1988; Echeverria, 1997; Faivovich, 2002; Vera Candioti et al., 2004); a reversal occurs in Lysapsus and Pseudis (de Sá and Lavilla, 1997; Vera Candioti, 2004). This character state is still unknown in Sphaenorhynchus and Xenohyla . Another possible morphological synapomorphy is the absence of keratinized nuptial excrescences. Duellman et al. (1997) and Duellman (2001) suggested that the absence of nuptial excrescences was a synapomorphy of the 30­chromosome Hyla . Nuptial excrescences are also absent in Lysapsus , Pseudis , Scarthyla , Scinax , some species of Sphaenorhynchus , and Xenohyla (Caramaschi, 1989; Duellman and Wiens, 1992; Faivovich, personal obs.; Rodriguez and Duellman, 1994). Note that, while pigmented keratinized structures are absent in all these groups, nuptial pads are present at least in some species of Dendropsophus , Scarthyla , and Scinax (Faivovich, personal obs.).
