Margyricarpus pinnatus is a poorly understood entity from natural grasslands of South America that it better considered as a species complex. In this work we contribute to the advancement of the taxonomic knowledge of this challenging species complex by describing two new species of Margyricarpus from southern Brazil. We present field photographs, illustrations, a distribution map and ecologic and conservation notes on the new species.

Two new species of Notogynaphallia Ogren & Kawakatsu, 1990, from South Brazil, are described. Notogynaphallia pseudoceciliae sp. nov. and Notogynaphallia arturi sp. nov., present elongate bodies with parallel margins and the dorsum with five dark longitudinal stripes on a yellowish background. Additionally, N. arturi has two large lateral bands of brown pigment between the paramedian and lateral stripes. Both species, which are appended to a complex of striped species previously described for the genus Notogynaphallia, show a unique combination of characters of external and internal morphology.

Two new species of Nullana DeLong, 1980 are described and illustrated: N. albinoi sp. nov. and N. sakakibarai sp. nov., both from the state of Paraná, Brazil. Two new synonyms and a new combination are proposed. A key to the 10 known species of Nullana are presented and Nullana gelbana is newly recorded from Paraná State, Brazil.

The genus Obama Carbayo et al., 2013 includes 38 species, being the most species-rich within Geoplaninae. Species of this genus show a similar anatomy regarding their copulatory apparatus, which may hinder species differentiation. In this study, we describe two new species, presenting a marbled colour pattern, found in two different phytophysionomies of the Atlantic Forest, namely Semi-deciduous Forest and Araucaria Forest. Both species can be distinguished from their congeners, as well from each other, by colour pattern and eye arrangement combined with characteristics of the pharynx, penis papilla and prostatic vesicle, confirmed by molecular analyses from cytochrome c oxidase subunit I gene (COI). Phylogenetic analyses suggest that both species herein studied are closely related to another species that occurs in areas of Araucaria Forest (O. maculipunctata). Results also indicate the need to use at least 600 bp of the gene COI in the definitions of interspecific divergences and for species delineation, at least for the genus Obama.

Members of the Crotalus durissus species complex are widely distributed from Mexico to Argentina in areas with mainly seasonally dry tropical deciduous forest. Although four species (C. culminatus, C. durissus, C. simus and C. tzabcan) are currently recognized, species limits remain to be tested. Previous genetic studies suggest that C. durissus and C. simus may be paraphyletic and that at least one cryptic species may be present. We analyzed 2596 bp of DNA sequence data from three mitochondrial and one nuclear gene to infer phylogenetic relationships in the Neotropical rattlesnakes. We also examined museum and wild specimens as well as captive animals to analyze morphological characters. Our results suggest that the current taxonomy of the Crotalus durissus species complex does not reflect evolutionary history. We found strong support for five independent lineages within Crotalus simus (sensu lato), with genetic and morphological evidence for three previously recognized taxa and two new species, as well as three major lineages within C. durissus that each represent species hypothesis to be tested with additional evidence. We also found support to retain C. totonacus in the Crotalus molossus species complex. We suggest conservative taxonomic changes to the complex and related species, but more evidence is needed (e.g., morphology, ecology and venom composition) to clarify relationships among species.
