| uncovering the diversity in the amazophrynella minuta complex: integrative taxonomy reveals a new species of amazophrynella (anura, bufonidae) from southern peru. | a new species of the genus amazophrynella (anura, bufonidae) is described from the departments of madre de dios, cusco and junin in peru. an integrative taxonomy approach is used. a morphological diagnosis, morphometrics comparisons, description of the advertisement call, and the phylogenetic relationships of the new species are provided. amazophrynella javierbustamantei sp. n. differs from other species of amazophrynella by: intermediate body-size (snout-vent length 14.9 mm in males, n = 26 and ... | 2016 | 27047239 |
| further report of the occurrence of tetrodotoxin in atelopus species (family: bufonidae). | in alcoholic extracts from museum samples of the toads atelopus subornatus and a. peruensis tetrodotoxin and its analogues, 4-epitetrodotoxin and 4,9-anhydrotetrodotoxin were detected by fluorometric hplc analysis, extending the list of amphibians containing this toxin. however, the toxin was not detected in samples of melanophryniscus stelzneri, dendrophryniscus minutus and oreophrynella sp. | 1995 | 7597728 |
| the tadpole of amazophrynella manaos rojas, carvalho, gordo, ávila, farias and hrbek, 2014 (anura, bufonidae) from the type locality and adjacent regions at central amazonia, brazil. | the genus amazophrynella, as currently recognized (fouquet et al. 2012a, b), is represented by four nominal species (frost 2014; rojas et al. 2014) but the tadpoles of only one species, amazophrynella minuta (melin) from ecuador, have been described (duellman & lynch 1969; duellman 1978). amazophrynella manaos rojas, carvalho, gordo, ávila, farias and hrbek, 2014 occurs in the leaf litter of terra firme forest in the southwestern part of the brazilian guiana region (rojas et al. 2014). the tadpo ... | 2014 | 24990056 |
| a new species of amazophrynella (anura:bufonidae) from the southwestern part of the brazilian guiana shield. | amazophrynella is a genus of the family bufonidae, currently represented by three species. the type species of the genus, amazophrynella minuta, however, is a complex of species occurring throughout the amazonian biome. this group remains problematic taxonomically; the difficulty lays principally in the lack of diagnostic characters in the original description of a. minuta, the lack of molecular data and refined taxonomic comparison of individuals through its wide distribution. we describe a new ... | 2014 | 24872281 |
| redescription of the amazonian tiny tree toad amazophrynella minuta (melin, 1941) (anura: bufonidae) from its type locality. | the description of amazophrynella minuta was published in 1941 by the swedish naturalist douglas melin based on material from taracuá (amazonas state, brazil). this description was very brief and based on the morphology of few specimens with diagnostic characters and color variation not well defined. moreover, the type series is currently in poor state of conservation. consequently, taxonomic ambiguity surrounds the nominal taxon a. minuta, which hampers the description of many unnamed congeneri ... | 2018 | 30313811 |
