The Krasiejów locality in the Upper Triassic of southern Poland yields the tetrapod taxa Cyclotosaurus robustus (= C. intermedius), Metoposaurus diagnosticus (we reject proposed subspecies of this species), Stagonolepis robertsoni, Teratosaurus suevicus (= T. silesiacus), Parasuchus bransoni and Silesaurus opolensis. The occurrences of Parasuchus and Metoposaurus indicate the Krasiejów assembla...

In 1979, the first autochthonous case of Chagas disease in the Western Brazilian Amazon was reported and an entomological survey was carried out around it. Specimens of Rhodnius pictipes and Rhodnius robustus were collected in intradomicile and sylvatic ecotopes. Adult bugs were infected with trypanosomatids. Invasion of houses by triatomines was demonstrated and the presence of infected bugs i...

We provide in this study a very large DNA dataset on Rhodnius species including 36 samples representing 16 valid of the three groups, pictipes, prolixus and pallescens. Samples were sequenced at low-depth with whole-genome shotgun sequencing (Illumina technology). Using phylogenomics 15 mitochondrial genes (13.3 kb), partial nuclear rDNA (5.2 kb) 51 protein-coding (36.3 we resolve sticking poin...

The complete amino acid sequence of versutoxin, a lethal neurotoxic polypeptide isolated from the venom of male and female funnel-web spiders of the species Atrax versutus, was determined. Sequencing was performed in a gas-phase protein sequencer by automated Edman degradation of the S-carboxymethylated toxin and fragments of it produced by reaction with CNBr. Versutoxin consisted of a single c...
