Nopyllus gen. nov. is proposed to include Apopyllus isabelae Brescovit & Lise, 1993 and Nopyllus vicente sp. nov. from southern Brazil. Nopyllus gen. nov. is close to Apodrassodes Vellard, 1924 and Apopyllus Platnick & Shadab, 1984, can be distinguished from both genera by the absence of a dorsal abdominal scutum in males, the absence of a median apophysis on bulb, the curved, narrow and reniform cymbium, and by the presence of a very conspicuous cymbial basal projection.

Three new species of Callianthe (Malvaceae) from southern Brazil and northeastern Argentina are described, and illustrated: C. flava, C. maritima, and C. sulcatarinensis. Morphological descriptions, distribution maps, photographs, ecological notes, and a table comparing these species to two morphologically similar species, C. amoena and C. muelleri-friderici, are presented. Two of the three newly-described species, C. maritima and C. sulcatarinensis, so far are considered endemic and according to IUCN criteria, fit into the categories Endangered (EN) and Vulnerable (VU), respectively. A new combination C. costicalyx, based on Abutilon costicalyx, also is proposed.

Trichomycterus comprises about 170 valid species, but its monophyly has been challenged in the last decades. Bayesian Inference and Maximum Likelihood analyses comprehending mitochondrial genes COI and CYTB and nuclear genes GLYT, MYH6 and RAG2 from 71 Trichomycterinae terminal taxa and eight outgroups were performed. The analyses highly supports a clade containing Trichomycterusnigricans, the type species of the genus, and several other congeners endemic to eastern and northeastern Brazil, herein considered as the genus Trichomycterus, the sister clade the southern Brazil and adjacent areas clade; the latter clade comprises two subclades, one comprising species of the genus Scleronema and another comprising species previously placed in Trichomycterus, herein described as a new genus. Cambevagen. n. is distinguished from all other trichomycterines by the presence of a bony flap on the channel of the maxillo-dentary ligament, the interopercle shorter than the opercle, a deep constriction on the basal portion of the antero-dorsal arm of the quadrate, absence of teeth in the coronoid process of the dentary, the maxilla shorter than the premaxilla, the cranial fontanel extending from the the medial posterior of frontal to the medial region of supraoccipital, and absence of the postorbital process of the sphenotic-prootic-pterosphenoid.

Molecular Phylogenetic

During a taxonomic revision of species belonging to Phylloporia, some collections from the Atlantic Forest of southern Brazil previously determined as P. spathulata had morphological discrepancies in comparison to the type material of this taxon. Both molecular phylogenetic and morphological analysis revealed them to be two distinct species, described here as Phylloporia elegans sp. nov. and P. nodostipitata sp. nov. They mainly differ from P. spathulata by having reviving basidiomata with smaller pores and basidiospores. Phylloporia nodostipitata develops caespitose basidiomata with a knotted and flexuous stipe and a tomentose pileal surface. Phylloporia elegans develops solitary basidiomata with a cylindrical and straight stipe and a plagiotrichoderm pileal surface. Both species are described, illustrated, discussed and compared with Phylloporia spathulata based on a study of the type. Phylloporia spathulata sensu stricto is presented based on its basionym type material.

Fruit Size And Shape

A new South American species of Salacia (Celastraceae, Salacioideae) found in Colombia and Venezuela, Salacia fugax Lombardi & M.Serna is described here. It is characterized by its indument, small long acuminate leaves with short petioles, branched inflorescences, flowers with an annular-pulvinate disk, and small pyriform fruits. This new species resembles S. mennegana J.Hedin ex Lombardi and S. opacifolia (J.F.Macbr.) A.C.Sm. by its short petioles, leaf shape, slender branched inflorescence, perianth form, and similar disc, but S. fugax differs by its hairs, leaf size and apex, calyx, and fruit size and shape.

AbstractThe Old World cotton bollworm Helicoverpa armigera was first detected in Brazil with subsequent reports from Paraguay, Argentina, Bolivia, and Uruguay. This pattern suggests that the H. armigera spread across the South American continent following incursions into northern/central Brazil, however, this hypothesis has not been tested. Here we compare northern and central Brazilian H. armigera mtDNA COI haplotypes with those from southern Brazil, Uruguay, Argentina, and Paraguay. We infer spatial genetic and gene flow patterns of this dispersive pest in the agricultural landscape of South America. We show that the spatial distribution of H. armigera mtDNA haplotypes and its inferred gene flow patterns in the southwestern region of South America exhibited signatures inconsistent with a single incursion hypothesis. Simulations on spatial distribution patterns show that the detection of rare and/or the absence of dominant mtDNA haplotypes in southern H. armigera populations are inconsistent with genetic signatures observed in northern and central Brazil. Incursions of H. armigera into the New World are therefore likely to have involved independent events in northern/central Brazil, and southern Brazil/Uruguay-Argentina-Paraguay. This study demonstrates the significant biosecurity challenges facing the South American continent, and highlights alternate pathways for introductions of alien species into the New World.
