A New Species

Abstract— During a taxonomic and phylogenetic study of Xylopia from the Amazon River basin, South America, we examined collections from the Brazilian states of Amazonas, Mato Grosso, Pará, Rondônia, and Tocantins that resembled Xylopia nitida by some characteristics of the leaves, but differed consistently from the latter in a number of floral and fruit characters. On the basis of these specimens we describe here a new species, Xylopia maasiana. The new species is a small to medium-sized tree encountered mostly in riparian habitats across the southern Brazilian Amazon and in some transition areas between the Amazon forest and cerrado biomes in Central Brazil. In addition to the detailed description, we include a preliminary assessment of conservation status, taxonomic comments, illustrations, a distribution map of the new species, and comparison with X. nitida.

A new species of the cosmopolitan genus Xenylla Tullberg, 1869 is herein described and illustrated. The new species, Xenylla hodori sp. nov., from the Amazon Forest of Northern Brazil, resembles X. capixaba Fernandes & Mendonça, 2010 and X. welchi Folsom, 1916 due, the number of eyes, chaetotaxy head and shape of furca. X. hodori sp. nov. is the second species recorded for the Brazilian Amazon Region.

A new species, Amblydromalus amazonicus n. sp. is described and illustrated based on adults of both sexes. Individuals were found in association with plants in natural vegetation (Amazon Forest), on uncultivated plants in guarana crops, and on exotic fruit (residential area), in states of Amazonas and Mato Grosso, Brazil. The type material of A. akiri Nuvoloni, Lofego, Rezende and Feres was re-examined and the number of setae as well as the chaetotaxy of genu III is corrected. Notes on the occurrence of Amblydromalus in South America and a key to species of genus for this subcontinent is provided.

A New Species

Passovia (Loranthaceae) is a Neotropical genus of mistletoes characterized by having inflorescences with triads and flowers with laterally excavated filaments and basifixed anthers. During the revision of Loranthaceae for the Flora do Brasil 2020 project, a single collection of an undescribed species of Passovia was found at the Museum Paraense Emilio Goeldi herbarium (MG). We described and illustrated this specimen as Passovia bracteata, a new species endemic from the Brazilian Amazon Forest. This new species is characterized by its terete stems, ovate leaves, racemose inflorescences (compound at the base), and pedunculate triads with a long-foliaceous bract subtending the median flower of the triad and/or the whole triad.

A New Species

Phytoseiidae (Acari: Mesostigmata) is one of the most studied mite families due to their use in biological control programs. The southwestern region of Mato Grosso State, Brazil remains poorly explored concerning its mite fauna. Therefore, the aim of this study was to conduct a survey of Phytoseiidae mites in the southwestern region of Mato Grosso State, Brazil. Samplings were carried out in three areas, representing the following: Amazon Forest (AF), Cerrado (CE) and Pantanal (PA) biomes. Five species of native plants commonly found throughout the areas were selected, as well as five others exclusive for each area. In total, five individuals from each plant species were collected. Thirty mite species belonging to 16 genera were recorded: AF (14 species), CE (15) and PA (23). The three most abundant species in this study belongs to the genus Amblyseius: A. acalyphus Denmark & Muma, A. aerialis (Muma) and A. chiapensis De Leon. In the AF the most abundant species were A. aerialis, A. chiapensis and Euseius concordis (Chant); in the CE were A. acalyphus, A. chiapensis and Typhlodromips furcus Lofego, Demite & Feres; lastly in the PA were A. acalyphus, A. aerialis and T. furcus. The plants which harbored the highest richness were common to the three biomes: Physocalymma scaberrimum Pohl (Lithraceae) (12), Cecropia pachystachya Trécul (Urticaceae) (11) and Siparuna guianensis Aubl. (Siparunaceae), (11). A new species, Amblyseius matogrossensis sp. nov., is described and illustrated.

A New Species

Miconia waimiri-atroari is presented here as a new species from the Brazilian Amazon Forest. This new species has discolorous leaf blades, inflorescences with scorpioid branches, and petals and antesepalous stamen connectives with glandular trichomes. It has been misidentified as Miconia argyrophylla, another species from the Amazon Forest that has this same set of characters. However, the new species has cylindrical young branches (vs. quadrangular in M. argyrophylla), stellate trichomes on leaf abaxial surface (vs. arachnoid), stamens with yellow filaments that turn red in old flowers (vs. stamens with white filaments that only turn pale in old flowers), and style with glandular trichomes (vs. glabrous). At the moment, the species is only known from a small area north of Manaus, state of Amazonas, Brazil. Morphological description, illustrations, general comments and comparison to other similar species are also provided.

We present novelties in Thismiaceae for the south of the Brazilian Amazon, resulting from botanical expeditions in the north of the Mato Grosso State. The occurrence of four species is recorded: Thismia hyalina; T. melanomitra; T. singeri and a species new to science: T. ribeiroi. These are the first records of the family Thismiaceae, as well as of the genus Thismia and these species for the Mato Grosso State. Thismia melanomitra is a new species for the flora of Brazil and T. singeri is the second record of the species for Brazil. In this study, we also describe and illustrate the new species Thismia ribeiroi.
