The Cerrado domain is the most diverse savannah biome in the world and a biodiversity hotspot for conservation. Only a few areas of the domain remain well preserved, among them the Jalapão region in Tocantins State, currently is considered the best preserved area of the Brazilian Cerrado. Listed in a recent Angiosperm checklist for the region, there were two species of Polygala series Trichospermae, which were recognized as new by the first author. Polygala bringelii sp. nov., endemic to the Jalapão region, is diagnosed by its obclavate seeds without a ring of trichomes at their base, keel with the crest shorter than the cuculus, and the internal sepals (wings) longer than the capsule. Polygala tocantinensis sp. nov., endemic to Tocantins state, is distinguished by its internal sepals (wings) with two glands near to the rounded apex, and a ring of convergent trichomes at the base of the seeds. The two species are morphologically closest with Polygala trichosperma of sect. Timutua, series Trichospermae, but differs in its corolla and seeds shape and pubescence. An identification key, photographic plates, photos of floral parts under magnification, preliminary conservation assessments, and ecological comments of both species are also provided.

The Brazilian Atlantic Forest is one of the most diverse biomes in the world. The state of Bahia includes an important portion of the central corridor of Atlantic Forest that runs along the Brazilian coast. Myrtaceae is a dominant family of trees in this biome, and among its genera, Plinia is a genus notable for high number of endangered species in the Bahia Atlantic Forest. Plinia ybotyrype is here described, discussed and illustrated. An identification key for related species is also provided.

Abstract Background Pollen limitation occurs widely and has an important effect on flowering plants. The East Himalaya-Hengduan Mountains region is a global biodiversity hotspot. However, to our knowledge, no study has synthetically assessed the degree of pollen limitation in this area. The present study aims to reveal the degree of pollen limitation for the flowering plants growing on East Himalaya-Hengduan Mountains and to test whether the reproductive features or the elevation is closely correlated with the degree of pollen limitation in this area. Results We complied data from 76 studies, which included 96 species and 108 independent data records. We found that the flowering plants in this area undergo severe pollen limitation [overall Hedges’ d = 2.004, with a 95% confidence interval (1.3264, 2.6743)] that is much higher than that of the flowering plants growing in many other regions around the world. The degree of pollen limitation was tested to determine the correlation with the capacity for autonomous self-reproduction and with the pollination pattern (generalized vs. specialized pollination) of plants. In addition, we found a clear relationship between elevation and the degree of pollen limitation, which indicates that plants might undergo more severe pollen limitation in relatively high places. Conclusions This paper is the first to address the severe pollen limitation of the flowering plants growing in East Himalaya-Hengduan Mountains region. Moreover, we reveal the positive correlation between elevation and the degree of pollen limitation.

This new species is morphologically similar to an endangered species endemic to Far East Russia, Holopogon ussuriensis Komarov & Nevski, but differs in having green flowers (vs white) and light green pubescence (vs red). Its conservation status and an identification key to Holopogon are provided.

Taxonomic notes and Corrigendum for the manuscript entitled “Ichneumonid wasps of the subfamily Mesochorinae (Hymenoptera: Ichneumonidae): new replacement names, combinations and an updated key to the World genera” ARAUJO et al. (2018), Zootaxa, 4521: 052–060.

Large Genus

Mesochorinae is a widely distributed subfamily of ichneumonid wasps with approximately 900 described species (Yu et al., 2012), of which almost 90% belong to the cosmopolitan genus Mesochorus Gravenhorst (Broad et al., 2018). Since it is a very large genus, it has become a group of complex taxonomy and with numerous taxonomic conflicts (Araujo et al., 2018). Recent efforts were made aiming to resolve nomenclature problems present within Mesochorus (see Araujo & Vivallo, 2015; Kittel, 2016; Araujo et al. 2018). Specifically, Araujo & Vivallo (2015) and Araujo et al. (2018) proposed a total of 19 replacement names, of which two became primary homonyms of existing names (listed below) and seven were invalid, as Kittel (2016) and, in one case, Schwenke (2002), had previously proposed respective replacement names. Furthermore, Araujo et al. (2018) published an identification key for the World genera of Mesochorinae which includes Incurvarion Kasparyan. However, this genus was implicitly synonymized with Neurogenia Roman (Ctenopelmatinae: Perilissini) when Reshchikov et al. (2014) transferred the type (and only included) species, I. gorochovi Kasparyan, to Neurogenia. To resolve the taxonomic conflicts that remain within the subfamily Mesochorinae, seven new synonymies and two replacement names are proposed herein, together with a corrigendum for the identification key proposed by Araujo et al. (2018).

Different Parts

Palm houses and other greenhouses, due to maintaining constant temperature and humidity, allow the cultivation in Europe of plants from different parts of the world, even from tropical regions. However, sometimes they are also a habitat for alien species of spiders, mites, insect, etc. These animals have been introduced accidentally with contaminated plants, seeds, seedlings, soil and thanks to stable conditions maintained in greenhouses, they may colonize these places. Example of arthropods, of which even tropical species occur in several greenhouses, are oribatid mites – minute saprophagous arachnids that mostly inhabit soil. In Europe they are represented by about 2,000 species, while worldwide – over 10,000 taxa were described. The aim of this research was to investigate the selected greenhouses for the biodiversity of oribatid mites and the presence of non-native species. In total, 49 taxa were recorded, including 23 alien species (for example, a Neotropical taxon Galumna hamifer, or Oriental Suctobelbella parallelodentata). These results confirm that greenhouses are the places of occurrence of many alien oribatid species. The obtained results may be used in future research on the biology of poorly known tropical mites.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.
