Brazilian protected areas are essential for the conservation of plants of the Atlantic Forest domain, one of 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the richness of plants protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism, and conservation in the PNC that could not be included in the list. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN, or VU) by the Brazilian National Red List, seven as data deficient (DD), and five as priorities for conservation."Parque Nacional do Caparaó" houses 8% of the land plant species endemic to the Brazilian Atlantic Forest, including 6% of its angiosperms, 31% of its lycophytes and ferns, and 14% of its avascular plants. Twelve percent of the threatened species listed for the state of Espírito Santo and 7% listed for the state of Minas Gerais are also protected by PNC. Surprisingly, 79% of the collections analyzed here were carried out in Minas Gerais, which represents just 21% of the total extension of the park. The compiled data uncover a huge botanical collection gap in this federally protected area.

A new Brazilian Protoneurinae damselfly, Forcepsioneura lopii sp. nov. (holotype male deposited in DZUP: Brazil, São Paulo State, Cananéia, Ilha do Cardoso State Park) is described, and diagnosed based on two males and one female. This small dark yellow-orange Forcepsioneura Lencioni, 1999, inhabits typical restinga-like formations in southern Brazil. The coloration and short ventrobasal process of the male cercus of Forcepsioneura lopii sp. nov. make it similar to the larger montane species of the orange-black group, i.e., F. grossio¬rum Machado, 2005, F. itatiaiae (Santos, 1970), F. janeae Pimenta et al., 2019, F. lucia Machado, 2000, and F. serrabonita Pinto & Kompier, 2018. However it occurs in lowlands and the cercus is slender as in the light blue group, i.e. F. gabriela Pimenta et al., 2019, F. garrisoni Lencioni, 1999, F. haerteli Machado, 2001, F. regua Pinto & Kompier, 2018, and F. sancta (Hagen in Selys, 1860). The very acute, spur-like process on the mediobasal process of male cercus is unique. This is only one of several undescribed species recently discovered in For¬cepsioneura, and it reaffirms the necessity for additional investigations to understand the richness and diversification of this genus.

The new bulimulid species, Drymaeus currais sp. nov., is described based on shell and anatomical features. It is endemic of Guapirá Island, belonging to the Currais Archipelago, a small protected area off Paraná coast. The species is thus, based at least on endemicity, endangered. It has as closest species D. castilhensis, another endemic species of Castilho Island, ~70 km northwards. Its main exclusivities are a banded shell (except for periumbilical area); a ureter ~1/3 opened (furrow); an external anus; a slightly different buccal and intestinal arrangement; a penis lacking internal chambers; a small receptacle with a genital appendix.

We report here a new species belonging to Nephus (Nephus) Mulsant. Nephus (Nephus) apolonia sp. nov. was collected in the Reunion Island (Mascarene Archipelago, Indian Ocean). We describe this new species and redescribe and illustrate three other Nephus species already known from Reunion: Nephus (Nephus) oblongosignatus Mulsant, 1850, Nephus (Geminosipho) reunioni (Fürsch, 1974) and Nephus (Nephus) voeltzkowi Weise, 1910. Furthermore, we present a phylogenetic tree for these four species and calculate the genetic distances between them, using high-throughput DNA sequencing of the mitochondrial genome. The similar external morphology of N. apolonia sp. nov. and N. voeltzkowi very probably explains why individuals from the first species have been mistakenly identified as the latter and were not recognized as different until now. Other than external and genitalia traits, the present study provides molecular evidence confirming these are indeed two different species.

The florbella group of Miconia is composed of four species from the central Andes that are characterized by hollow stems inhabited by ants, and pleiostemonous flowers with a calyptrate calyx. The four species are M. inusitata, and the newly described here M. cava, M. florbella, and M. valenzuelana. The combination of pleistemonous flowers and calyptrate calyces suggests that these species could be placed in the former Conostegia, but at least three of the four species discussed here (M. florbella, M. inusitata and M. valenzuelana) do not belong in that clade and are more closely related to other species of Andean Miconia. All four species grow in undisturbed areas in low- to middle-elevation forests in the Andes.

A continuous spectrophotometric assay for the screening of PHB depolymerase activity in microtiter plates was developed. We evaluated crystalline PHB in the suspension and coated it with the addition of a pH indicator to detect the breakage of the ester bond by proton titration. The reaction rate and the con

Any bioassay to test new chemically synthesized larvicides or phytolarvicides against <i>Culicidae</i> and more harmful mosquito species, such as <i>Aede</i>s <i>aegypti</i> and <i>Aedes albopictus</i>, which specifically transmit dengue, yellow fever, chikungunya viral fevers as well as Zika virus, or <i>Anopheles gambiae</i>, a vector for malaria and philariasis, requires thousands of well-developed larvae, preferably at the fourth instar stage. The natural morphogenetic cycle of <i>Aedes</i> spp., in the field or in the laboratory, may extend to 19 days at room temperature (e.g., 25°C) from the first permanent contact between viable eggs and water and the last stage of larval growth or metamorphosis into flying adults. Thus, accelerated sequential molting is desirable for swifter bioassays of larvicides. We achieved this goal in <i>Aedes aegypti</i> with very limited strategic and low-cost additions to food, such as coconut water, milk or its casein, yeast extract, and to a lesser extent, glycerol. The naturally rich coconut water was excellent for quickly attaining the population of instar IV larvae, the most advanced one before pupation, saving about a week, for subsequent larvicidal bioassays. Diluted milk, as another food source, allowed an even faster final ecdysis and adults are useful for mosquito taxonomical purpose.
