Background: The genus Carnus Nitzsch, 1818 comprises small ectoparasites that feed on the blood of juvenile avians. They are characterised by dealated adults with setose abdominal intersegmental membranes. Carnusorientalis Maa, 1968 was previously recorded in Malaysia and the Ryukyu Islands of Japan, parasitising two owl species: Ketupaketupu (Horsfield, 1821) and Otuselegans (Cassin, 1852). This study confirms the occurrence of C.orientalis in Taiwan and presents a new host record, along with COI barcode sequences. Additionally, the study also elucidates the difficulties posed by blood meal contamination and pseudogene amplification as confounding factors intrinsic to the molecular taxonomic delineation of C.orientalis via universal DNA barcoding primers.

New information: The following new information regarding C.orientalis is provided in this study: Carnusorientalis is first recorded in Taiwan, filling the gap in its East Asian distribution. This is also the first record of Carnidae from Taiwan.Otuslettia (Hodgson, 1836) (Aves, Strigidae) is reported as a new host for C.orientalis, identified on a fallen fledgling.Co-amplification of the host's COI is reported in this study using the universal PCR primer set LCO1490/HCO2198. Additionally, the amplification of a COI-like pseudogene using a newly-designed primer set is detected through abnormal translated amino acid sequences and the occurrence of a stop codon.New specific primers for the COI gene of Carnus were designed in this study. The new distribution and ecological data of C.orientalis enhance our understanding of this species. The provision of new COI primers is anticipated to contribute to future studies employing DNA barcoding in bird-parasitic flies.

Background: The genus Micrencaustes Crotch, 1876 (Coleoptera, Cucujoidea, Erotylidae, Erotylinae, Encaustini) includes 44 known species worldwide, 11 species having been reported to occur in China. In recent years, species of genus Micrencaustes in China are constantly being discovered, mainly distributed in southern China.

New information: A new species, Micrencaustes (Mimencaustes) occulta sp. nov., is described and illustrated. Two species, Micrencaustes (Mimencaustes) divisa Arrow, 1925 and Micrencaustes (Micrencaustes) navicularis Arrow, 1921 are recorded from China for the first time. The morphological characteristics of adults of new species are re-described in detail and illustrated. A key to Chinese species of the genus Micrencaustes is provided. The specimens of new species was collected from Yunnan Province and the specimens of Micrencaustes (Mimencaustes) divisa Arrow, 1925 and Micrencaustes (Micrencaustes) navicularis Arrow, 1921 were collected from Hainan Province and Guangdong Province and deposited in the Museum of Hebei University and Institute of Zoology, Chinese Academy of Sciences.

The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arrivals to the Archipelago and from addressing specific taxonomic lacunae. Here, we update the taxonomic terrestrial arthropod biodiversity of the Azores by reporting for the first time 13 species for the Archipelago, namely Oligonychusperseae Tuttle, Baker & Abbatiello, 1976, Textrixpinicola Simon, 1875, Pholcommagibbum (Westring, 1851), Schistocercagregaria (Forsskål, 1775), Phoracantharecurva Newman, 1840, Diachusauratus Fabricius, 1801 Phyllotretaprocera (Redtenbacher, 1849), Phyllotretastriolata (Fabricius, 1803), Diboliaoccultans (Koch, 1803), Pseudolynchiacanariensis (Macquart, 1839), Hermetiaillucens (Linnaeus, 1758), Dryocosmuskuriphilus Yasumatsu, 1951 and Ectemniuscephalotes (Olivier, 1792), and several new species records for specific islands. These species benefitted from the increase in transportation of goods and commodities, both from outside the Archipelago and between islands, to arrive and spread across the Archipelago with some of them posing new challenges to local agriculture, forestry and biodiversity conservation management.

Background: The tribe Tropidocephalini is the second largest tribe of the subfamily Delphacinae, comprising 204 species of 37 genera worldwide. Most species in this tribe feed on bamboo (Bambusoideae) or grasses (Poaceae). In Korea, only three species have been reported.

New information: This tribe is represented by four species in South Korea, including a newly-recorded species, Epeurysadistincta Huang & Ding, 1979. Descriptions and illustrations of the four species and a revised key for the identification of the tribe Tropidocephalini are provided.

Background: The genus Leptobrachella (Anura, Megophryidae) was originally described, based on the type species from Sarawak (Malaysia), Leptobrachella mjöbergi Smith. The taxa in the group were previously classified into different genera, i.e, Paramegophrys Liu; Leptolalax Dubois; Lalax Delorme, Dubois, Grosjean & Ohler; and Lalos Dubois, Grosjean, Ohler, Adler & Zhao. However, Yuan et al. synonymised Leptolalax with Leptobrachella in 2017. Members of Leptobrachella inhabit the forest floor and rocky streams in hilly evergreen forests. They are widely distributed from southern China and Myanmar through mainland Indochina to Peninsular Malaysia and the island of Borneo. However, the species diversity of the genus was indicated to be underestimated by phylogenetic analyses and a series of new species have been discovered recently. In Vietnam, 34 species of Leptobrachella are currently known and 75% (or 24 species) have been described or newly recorded from the country since 2010.

New information: We describe a new species, Leptobrachellahuynhi sp. nov., from Sin Ho District, Lai Chau Province. The new species is distinguished from its congeners by genetic divergences ranging from 3.62 to 18.51% (16S rRNA gene) and morphological differences: size medium (SVL 37.8-40.2 mm in adult females); head longer than wide; tympanum distinct; skin on entire dorsum shagreened; toes without webbing and with narrow lateral fringes; supratympanic ridge slightly rough with few nodules; dorsum grey-brown with indistinct dark brown markings; an interorbital region with a stacking double Y-shaped marking; centre of belly creamy-white, outer edges of belly brown with small whitish spots; iris copper. The new species is the 35^th species of the genus Leptobrachella known from Vietnam.

Background: The genus Hydrurus contains a solitary species, Hydrurusfoetidus. Its thalli exhibit a remarkable structure, consisting of a firm central axis surrounded by peripheral branches, all enveloped within a viscous, gelatinous coating. Molecular data pertaining to the genus Hydrurus are scarce, necessitating further investigation into its phylogenetic relationships.

New information: A new site with benthic freshwater alga Hydrurusfoetidus (Villars) Trevisan has been discovered in the Fenhe River in Shanxi Province, China. The physical and chemical parameters of water were meticulously measured and documented. Detailed morphological observations were conducted on the specimen, measuring different cell categories. The SSU, LSU, ITS and rbcL DNA sequence data of H.foetidus collected from Shanxi were determined. An extensive three-gene phylogenetic tree was constructed, revealing a strong relationship between the specimen in this study and H.foetidus specimen from Norway. Time-calibrated molecular phylogenetic analysis further indicated that the genus Hydrurus diverged approximately 125 million years ago (Early Cretaceous), while the two H.foetidus strains from Shanxi, China and Norway diverged approximately 6 million years ago (Neogene). The results of this study supplement new molecular evidence for H.foetidus and contribute significantly to our understanding of the geographical distribution and evolutionary history of the genus Hydrurus.

Background: A new species of the genus Rhopalopsole (Plecoptera, Leuctridae) from Yunnan Province, China, Rhopalopsoledulongjianga sp. nov., is described and illustrated.

New information: This new species is compared to the similar species, Rhopalopsolebispina (Wu, 1949). Additionally, we provide a supplemental description and colour plates of R.bispina. A key to Rhopalopsole species from Yunnan Province, China, is also provided in this paper.

Background: The Parque Estadual do Forno Grande is a fully protected area in the southern Espírito Santo State, Brazil. It belongs to the Atlantic Forest domain, with predominantly dense, ombrophilous, seasonal semi-deciduous forests and herbaceous/shrubby vegetation on rock outcrops. The area is recognised as highly important for conservation, designated as a priority biological area for protecting the Atlantic Forest's biodiversity. Although the importance of Protected Areas in conserving the Atlantic Forest biodiversity is unquestionable, it is crucial to understand the floristic patterns within these regions to develop effective conservation strategies. We utilised national online databases to compile species lists containing relevant information about their biodiversity. The updated list of vascular plants recorded in the Parque Estadual do Forno Grande is available in the "Catálogo de Plantas das Unidades de Conservação do Brasil" and it is presented here with further information on richness, endemism and conservation status.

New information: The Parque Estadual do Forno Grande harbours 958 species of vascular plants, of which 79.2% are angiosperms, 18.4% are ferns and 2.4% are lycophytes. Amongst these species, 44% are endemic to the Atlantic Forest. There are 58 threatened species, of which six are Critically Endangered, 39 are Endangered and 13 are Vulnerable. Amongst the threatened species, 51 are endemic to the Atlantic Forest. The number of records and the species richness in this area are notably high for Atlantic Forest standards. Our findings suggest that floristic inventories of Brazilian Protected Areas are a key contribution to the general perception of how much we still do not know about our flora. It also highlights the necessity of supporting floristic surveys in poorly-known areas, especially those remaining as forest remnants.

Background: The paper presents novel findings of little-known species of rodents, the blind tree mice Typhlomys in Son La Province, Vietnam, with the first morphological and genetic characterisation and taxonomical description of the new species, T.taxuansis. The study also summarises all the data available on this genus species distribution, museum collections and notes on its taxonomy, which are important to establish the proper conservation status of the species. An exhaustive map of the findings is provided, along with a refined taxonomic key for all six currently morphologically characterised species of the genus. It is shown that, based on the data available to date, the genus is still far from complete. Most species, apparently, do not need a special conservation measure; their status may be established as Least Concerns and Near Threatened (B1a+2a) and the current population trend is stable (IUCN).

New information: The paper introduced innovative findings regarding lesser-known rodents, the blind tree mice Typhlomys in Son La Province, Vietnam, along with the primary morphological and genetic identification and taxonomic explanation of the novel species T.taxuansis.

Measuring the use of natural history collections is essential to understand their past and present impact on science, to underpin decisions about their management and to assist with deploying them optimally to address societal challenges. Using the vast natural history collections of Naturalis Biodiversity Center as an example, this paper assesses the significance and relevance of quantifying collection use. Four aspects are discussed: 1. standardisation, 2. relevance of having standardised metrics on collection use, 3. the level of detail and completeness of the information and 4. the interactions between digitisation of collections and physical collection use. Based on a set of transparent and objective parameters to describe collection use, it is proposed to further develop these into international standards.
