An examination of herbarium specimens and type material shows Reevesia orbicularifolia is conspecific with R. orbicularis, which is distributed in Vietnam. Therefore, R. orbicularifolia is reduced as a synonymy of R. orbicularis. A new species R. napoensis from northwestern Guangxi, China is described and illustrated. The new species is similar to R. rotundifolia and R. orbicularis but differs in having 7-veined cordate leaf blades, three bracts, 4-lobed sepals, and glabrous petals.

The Sierra de las Nieves National Park, declared by the Spanish Government in July 2021, is part of the Serranía de Ronda (Western Baetic mountains), which is considered one of the main centres of biodiversity and endemicity of the southern Iberian Peninsula (Andalusia, Spain) and the Mediterranean Basin. The park and its surroundings have an important diversity of vascular plants, mainly due to the orographic, climatic and geological diversity of the area, which is divided into three biogeographical sectors: Rondeño sector (limestones, dolomites and clays), Bermejense sector (peridotites and serpentines) and Aljíbico sector (gneisses and micaschists). This contribution presents the first catalogue of the vascular flora of this national park and its surrounding area, with 1,387 taxa distributed in 104 families and 542 genera. An amount of 79 taxa are endemic to Andalusia and 57 are endangered: 4 are Critically Endangered (CR), 17 are Endangered (EN) and 36 are Vulnerable (VU).

A catalogue of type specimens deposited at the herbarium of Chongqing Natural History Museum (CQNM) is carried out. A total of 62 specimens belonging to 56 gatherings concerning 37 valid published names in 23 families of Chinese seed plants are documented as original materials. They include seven isotypes, 21 syntypes, of which 16 of them are isolectotypes and 34 paratypes. A checklist of the 37 names is presented with annotations on the typification, authorship citation, type localities and other taxonomic issues. Eight names were lectotypified, and one name’s second-step lectotype is proposed. Additionally, Distylium lanceolatum Chun, which is invalid pending for further study, and which has long been treated as a synonym of D. dunnianum H.Lév., is listed after the 37 names.

The grasshopper Subfamily Gomphomastacinae (Orthoptera: Acridoidea: Eumastacidae) is widely distributed in the Qinghai-Tibetan Plateau and Central Asia. This paper describes three new species: Ptygomastax nihilsulcus Ge, sp. nov. Phytomastax pentaspinula Ge, sp. nov. and Pentaspinula unispinula Ge, sp. nov. of the subfamily from the eastern Qinghai-Tibetan Plateau, along with an updated identification key of species of the related genera. Detail figures of the body and genitalia of the new species are also provided.

A new species Durio gerikensis (Malvaceae) is described from Hulu Perak, Peninsular Malaysia, it can be easily recognised in the field by its reddish-pink flowers and small (6–7.5 cm in diameter), golden yellowish to pale yellow fruits with persistent calyx. It is unique from all the congeneric taxa by having two to four valved fruits with arilless seeds. Morphologically, Durio gerikensis is similar to D. lanceolatus Mast. (Masters 1875:499) and D. singaporensis Ridl. (Ridley 1916: 143) but they differ in their leaf, flower and fruit characteristics.

In this study, we used an integrative approach combining morphological and molecular data with ecology, in order to clarify the identity of a Dombeya newly recorded as occurring in Mayotte. Morphological and molecular evidence are in agreement and convincingly show that specimens of this newly recorded species can be confidently assigned to D. rosacea, previously known only from four herbarium sheets from Madagascar. The new populations of this species in the Comoros significantly expand the extant area of occupancy of D. rosacea. Ecological preferences are also discussed, as populations of D. rosacea were found in greatly contrasting sub-humid habitats. This newly reported geographical disjunction between the Comoros and Madagascar strengthens the evidence for a biogeographic connection between the floras of these two regions.

A new species of Helicteres from the Dominican Republic is described and illustrated; increasing the number of species occurring in the Caribbean to five. The new species, H. pegueroi, can be distinguished from H. jamaicensis and H. semitriloba by its habit and calyx and corolla colour, i.e. it is a shrub with red calyces and corollas; its pseudoactinomorphic flower due to a slight curvature at the base of the androgynophore; and its densely woolly, globose fruit. An artificial, dichotomous key is provided to distinguish the new species from the other species of the Caribbean region and Mexico.

A new Waltheria species (Malvaceae) is described and illustrated here. Waltheria glabribracteata is known from ecotone areas in Brazil and Bolivia and can be readily distinguished from other Waltheria species by its bracts which are glabrous on the adaxial surface. This study presents a description of the new taxon, taxonomic comments, a distribution map, conservation status and an illustration.

Monograph The Quiçama National Park (PNQ), located in Luanda Province, Angola, is one of the oldest protected areas in the country. Although some work has been done on the flora of the Park, up to now a comprehensive record of the vascular plant species has been lacking. The objective of the present study was to produce an inventory of the vascular plant diversity of PNQ, as well as to record the types of vegetation in which each species occurs, their habits, uses by local communities, common names, and conservation status. A total of 452 species were recorded, from 285 genera and 85 families. Two species are Pteridophytes, 99 are Monocotyledons, and 351 are Dicotyledons. The two largest families of the PNQ flora are the Fabaceae and the Poaceae. The Park hosts 14 species endemic to Angola, and one of them is restricted to this protected area. Of the 128 species with data on conservation status, 109 are considered of least concern, 13 are vulnerable, and six are endangered. Regarding useful plants, 237 species from 67 families were recorded. Of these, 196 are Dicotyledons and 41 are Monocotyledons. Most of them are used for medicinal purposes, the manufacturing of artefacts, and as sources of food info:eu-repo/semantics/publishedVersion

Rovnoxestus rasnitsyni gen. & sp. nov. is described from Eocene Rovno amber based on an adult female and fifth-instar nymph collected at a recently discovered locality at Perebrody, Rovno Province, Ukraine. The new fossil taxon is tentatively placed in Aphrodinae and resembles Xestocephalites Dietrich & Gonçalves from Eocene Baltic amber but has the hind femur macrosetal formula 2+2+1 and hind tarsomere I in both nymph and adult with an elongated inner preapical seta. This is the first species of Eocene leafhopper for which both the adult and nymph are described in detail.

A new genus, Mascarapion, is erected, endemic to the Mascarene Archipelago. Three species are included as new combinations: M. mauritii (Beguin-Billecocq, 1905), M. roudieri (Richard, 1957) and M. richardi (Alonso-Zarazaga, 1983). Mascarapion richardi is given a new status of distinct species, its morphological differences from M. roudieri are described. The problematic placement of the new genus in existing apionine tribes is discussed.

Two new species of eriophyoid mites viz. Abacarus sundarbanensis n. sp. infesting Pongamia glabra L. (Fabaceae) and Diptilomiopus augustifoliae n. sp. infesting Ambroma augusta (L.) (Sterculiaceae) respectively, are described from West Bengal, India.

A new species, Wikstroemia bokorensis (Thymelaeaceae), from Bokor National Park, Kampot Province, Cambodia, is described and illustrated. This species is morphologically most similar to W. nutans distributed in southern China and Vietnam, but differs in having pubescent branches and leaves, smaller anthers, a single disk scale, and glabrous ovary. DNA barcodes of ITS, rbcL, trnT-F, rps16, and rpl16 regions for the new species are also provided.

Triumfetta acahuizotlanensis is herein described and illustrated as a new species from the state of Guerrero, Mexico. The new taxon can be identified by the presence of tetramerous flowers, four glands in the androgynophore and piriform fruit.

The gracillariid genus Triberta gen. nov. (Lepidoptera: Gracillariidae: Lithocolletinae Stainton, 1854) is described to accommodate two species formerly assigned to the genus Phyllonorycter Hubner, 1822: Triberta helianthemella (Herrich-Schaffer, 1861) comb. nov. and T. cistifoliella (Groschke, 1944) comb. nov. Triberta cistifoliella bona sp. is restored from synonymy based on morphological characters. The new genus is biologically associated with the plant family Cistaceae of the order Malvales and is endemic to the Palaearctics. Our molecular analysis of eleven nuclear genes failed to unambiguously place Triberta in the lithocolletine phylogeny, but revealed that this genus is distinct from either clade Phyllonorycter + Cremastobombycia and Cameraria. The distinctiveness of Triberta is also supported by inferred traits in wing venation, micro morphology of the last instar larva, pupa, genital morphology of the adult and life history. A key to the species of Triberta is provided. The interspecific homogeneity in external morphology, coupled with minor differences in genital traits, an apparent narrow specialization on Cistaceae host plants, restricted geographical range and molecular evidence based on multi-nuclear genes jointly suggest that the generic diversification of Triberta is a relatively old phenomenon and driven strongly by host selection.

Dombeya sevathianii, a new endemic species from Mauritius, is described and illustrated. Based on its morphology, D. sevathianii belongs to the section Assonia as defined by Arenes and is closely related to D. populnea, endemic to La Reunion and Mauritius. These affinities are confirmed by a previous molecular study. The morphological diagnostic features for D. sevathianii are the cupuliform and entire epicalyx, and the absence of staminodes within the androecium. Given its known restricted distribution and small population, the species should be considered Critically Endangered (CR) as per the Red List Criteria of the International Union for the Conservation of Nature.

A revision of Conocephalus Thunberg and its relatives from China is reported. One new combination Conocephalus brevivalva (Shi et al., 2005), one new Chinese record Conocephalus oceanicus (Le Guillou, 1841) and one new species Conocephalus shanghaiensis sp. nov. are presented. The type specimens are deposited in the Shanghai Entomological Museum, CAS.

The buprestid genus Paragrilus Saunders, 1871 is reviewed for North and Central America. Of 18 species that are recognized, six are described as new: P. akersi, P. burkei, P. heliocarpi, P. moldenkei, P. fallorum, and P. azureus. Species fall into three species groups, the P. rugatulus group, the P. trifoveolatus group, and the P. aeraticollis group. Four species are considered to occur in the United States: P. burkei, P. lesueuri Waterhouse, P. rugatulus Thomson, and P. tenuis (LeConte). A key is given to separate species. Lectotypes are designated for P. laevicollis Waterhouse and P. trifoveolatus Waterhouse. All known adult hosts are in the Malvales (families Malvaceae, Sterculiaceae and Tiliaceae), two species have been reared (P. lesueuri and P. tenuis), and four species of the P. rugatulus group are known to associate with the genus Sida in the family Malvaceae.
