Abstract:
A new species of Ischnocnema is described from Serra da Mantiqueira, Municipality of Campos do Jordão, State of São Paulo, Brazil. The new species is a member of the Ischnocnema lactea Species Series. The new species differs from other species in the Ischnocnema lactea Species Series by its small size, snout sub-elliptical in dorsal view and acuminate-rounded in lateral view, and advertisement call. Descriptions of the dorsal coloration, advertisement call, and natural history are presented.

Abstract:
We describe a new species of Ischnocnema from the Serra da Bocaina mountain range, state of São Paulo, southeastern Brazil, based on morphological, bioacoustic, and mtDNA data. The new species is retrieved with high support values within the I. lactea species series as the sister species of I. spanios. Ischnocnema bocaina sp. nov. is characterized by its medium size (18.6–19.0 mm), a smooth venter, a rounded snout in dorsal view and acuminate in lateral view, a slightly expanded subgular, single vocal sac, a round and whitish, poorly-developed glandular-appearing nuptial pad on the dorsal surf

We describe a new species of Rain Frog from Brazil’s Atlantic Forest, which harbors high richness, endemism and threatened species of anurans. Ischnocnema crassa sp. nov. is a leaf litter breeder from the montane rainforest of Santa Teresa, state of Espírito Santo, southeastern Brazil. Remarkably, the new species is so far unique amongst Ischnocnema for having moderate hand webbing between fingers. Ischnocnema crassa sp. nov. is the third species belonging to I. parva series and we present a new phylogeny based on molecular data and propose a new diagnosis for the series. We provide field and

Abstract:
As many new evolutionary lineages are being discovered and formally named, sequencing topotypes when holotypes are not available becomes essential for taxonomy. This study uses a DNA-taxonomy approach to sequence new populations of the Ischnocnema verrucosa species complex (Brazilian Wart Frogs) from different locations, including, for the first time, individuals from the type localities. Phylogenetic analysis of the mitochondrial 16S gene recovered a monophyletic Ischnocnema verrucosa species series composed of three main clades.

Abstract:
Background The delimitation of cryptic species is a challenge for biodiversity conservation. Anurans show high cryptic diversity levels, and molecular species delimitation methods could help identify putative new species. Additionally, species delimitation approaches can provide important results for cryptic species conservation, with integrative methods adding robustness to results. Ischnocnema manezinho was described from Santa Catarina Island (SCI), southern Brazil. More recently, some inventories indicated continental populations supposedly similar in morphology to it.

Abstract:
The original description of Ischnocnema lactea (Miranda-Ribeiro, 1923) was based on two specimens and an inaccurate type locality. These circumstances have obscured the identity of this name. Moreover, the I. lactea species has had a complex taxonomic history and, in general, specimens of species in this group are poorly represented in amphibian collections. The diagnosis of the series is confusing, with many non-exclusive and variable characters barely useful. An accurate diagnosis for the series requires a precise characterization of I. lactea, its type species. Recently discovered populatio

Ischnocnema holti (Cochran, 1948) foi descrito com base em apenas um único indivíduo coletado no início do século XX no alto da Serra do Itatiaia. Neste trabalho é apresentada uma redescrição dessa espécie, baseada em 25 exemplares (18 machos e sete fêmeas), coletados na localidade-tipo. Medições dos exemplares, descrição da coloração em vida e aspectos de sua biologia e reprodução, observados em campo são incluídos. Ischnocnema holti é uma espécie de porte médio (comprimento rostro-anal: 13,5 a 31,7mm), vista dorsal e lateral arredondada e discos adesivos dos dedos bem desenvolvidos, e muita
