Abstract We detected N. girellae infections in 40 species belonging to 12 families of imported marine ornamental fish from a public aquarium in the Mexican state of Yucatan in January 2018 to December 2020 and carried out their identification to the species level using morphological and molecular analyses. Monogeneans were corroborated morphologically and molecularly using a partial sequence of 28S (region D1–D3) ribosomal DNA and analyzed in a molecular phylogenetic context in combination with data derived from other species of N. girellae available in GenBank. The phylogenetic tree revealed that the specimen found consistently belonged to the N. girellae clade. High infection parameters were detected of N. girellae in the hosts. This identification is relevant to aquarists and aquaculturists in the Gulf of Mexico because N. girellae is considered highly pathogenic in confined fish. Clearly, this work demonstrates that the importation of ornamental fish, coupled with deficient sanitary measures (lack of quarantine areas in distribution centres) contributes to the introduction of parasites and their establishment and dispersal within Mexico.

Diptera puparia may represent both in forensic and archaeo-funerary contexts the majority of the entomological evidence useful to reconstruct the peri and post-mortem events. Puparia identification is quite difficult due to the lack of identification keys and descriptions. In addition, external substances accumulated during the puparia permanence in the environment make the visualization of the few diagnostic characters difficult, resulting in a wrong identification. Six different techniques based on physical and chemical treatments have been tested for the removal of external substances from puparia to make identification at species level feasible. Furthermore, the effects of these methods on successful molecular analyses have also been tested as molecular identification is becoming an important tool to complement morphological identifications. The results of this study indicate that cleaning via warm water/soap, the sonication and treatment with a sodium hydroxide solution are the best methods to achieve a good quality of the samples.

A new species and eight new subspecies of Papilionoidea discovered in Vietnam between 2002 and 2020 are described and illustrated. The status of two taxa are revised. New taxa include Pieridae: Delias sanaca bidoupa Monastyrskii & Vu subspec. nov. and Talbotia naganum aurelia Monastyrskii & Vu subspec. nov.; Nymphalidae: Abrota ganga pulcheria Monastyrskii & Vu, subspec. nov.; Bassarona recta consonensis Monastyrskii & Vu, subspec. nov.; Pantoporia bieti aurantina Monastyrskii & To subspec. nov.; Ragadia latifasciata cristata Monastyrskii & Vu, subspec. nov.; Ragadia latifasciata crystallina Monastyrskii & Vu, subspec. nov.; Faunis indistincta luctus Monastyrskii & Vu subspec. nov. & Aemona gialaica Monastyrskii, K. Saito & Vu, spec. nov. The taxon infuscata Devyatkin & Monastyrskii, previously described as the subspecies Aemona tonkinensis infuscata, was elevated to the species level, while the taxon critias (Ragadia critias Riley & Godfrey) was reduced to a subspecies. Three Satyrinae species were recorded from Vietnam for the first time: Palaeonympha opalina Butler, 1871; Ypthima motschulskyi Bremer & Grey, 1853; and Ragadia latifasciata Leech, 1891.

Leucostegia has been long recognized as a small fern genus with only two species, L. immersa and L. pallida. Here we elevate a variety of L. immersa to species level and make the new combination Leucostegia amplissima based on morphological and molecular phylogenetic evidence. Morphologically, Leucostegia amplissima differs from L. immersa by having larger evergreen fronds, smaller indusia, and glandular hairs on the basal stipes. The study of Taiwanese populations further suggested an ecological divergence between L. immersa and L. amplissima.

A new cryptic lineage of bush frogs of the genus Raorchestes from the understudied Eastern Ghats of India is described. Molecular phylogenetic reconstructions using mitochondrial 16S rRNA gene sequences suggest that the new species belongs to the Raorchestes charius clade, is sister to the allopatric R. charius of the Western Ghats and support the species-level distinctiveness of the lineage. The new species morphologically resembles R. charius from which it can be distinguished using the following characters: narrower head (HW/SVL 0.31 vs 0.34–0.36), wider inter upper eyelid (IUE/SVL 0.14–0.16 vs 0.11–0.13), greater maximum upper eyelid width (UEW/SVL 0.10–0.12 vs 0.06–0.09) and shorter thigh (TL/SVL 0.32–0.43 vs 0.44–0.51). Acoustic observations from the breeding males further corroborate the distinct specific status of the new species. The discovery of this new species of bush frog from an understudied landscape suggests that additional extensive surveys in the Eastern Ghats would yield several more amphibian lineages yet unknown to science.

Scarce Data

Protura is a small class of Hexapoda, generally poorly known, and rather scarce data on its occurrence in caves are scattered throughout literature on fauna in caves and in some papers on Protura. Although the cave-dwelling fauna is relatively well studied in Slovenia, published records on Protura are rare. In this paper, data on the occurrence and abundance of Protura in Slovenian caves are considered. Various statistical analyses were performed to compare caves with Protura to those without in 60 intensively monitored cavities to detect any differences in the selected environmental conditions. No significant difference was obtained. Samples collected from 15 caves yielded 286 specimens identified to genus or species level. Ten species were identified: Acerentulus confinis (Berlese, 1908), A. rafalskii Szeptycki, 1979*, Acerentomon affine Bagnall, 1912*, A. balcanicum Ionesco, 1933*, A. italicum Nosek, 1969, A. maius Berlese, 1908*, A. meridionale Nosek, 1960, Acerella muscorum (Ionesco, 1930)*, Eosentomon armatum Stach, 1926*, and E. transitorium Berlese, 1908*. The seven species marked with an asterisk are new records for Slovenia. Two specimens belonging to an unidentified species of the genus Ionescuellum Tuxen, 1960 were also found. As expected, Protura were most abundant at the cave entrance close to the surface, and none of the species were found exclusively in cavities. This suggests that proturans were introduced passively into the cavities via organic matter and surface soils.

We re-examined the taxonomic status of plants treated as Sedum formosanum (Crassulaceae) from Miyako-jima Island of the Ryukyu Islands, Japan, using morphological comparison and molecular phylogenetic analyses with related species. In morphology, plants from Miyako-jima Island bore a close resemblance to the other plants of S. formosanum, but differed in being perennial, polycarpic, and having lateral axillary branches. Molecular analyses based on ITS of nrDNA and six regions of cpDNA sequencing indicated that the Miyako-jima plants formed a distinct subclade. This subclade was part of a polytomy with three other subclades comprising nine taxa endemic to Taiwan and S. formosanum from other areas, including the type locality. Therefore, we propose and describe the Miyako-jima plants as a new subspecies, Sedum formosanum subsp. miyakojimense.

Freshwater diversity, and diatoms in particular, from Desertas Islands (Madeira Archipelago, Portugal) is poorly known, although the Islands are protected and became a Natural Reserve in 1995. During two field expeditions in 2013 and 2014 to Deserta Grande Island, several freshwater and terrestrial habitats were sampled. The analysis of these samples aims to contribute to the biodiversity assessment of the freshwater biota present in Deserta Grande Island. Here, we present the diatom diversity in Deserta Grande Island resulting from that survey. This study contributes to improve the knowledge of Madeira Archipelago freshwater diversity, particularly in the Desertas sub-archipelago. To our knowledge, we present the first diatom data for the Desertas sub-archipelago. This work resulted in a list of 60 diatom taxa for Deserta Grande, from which 57 were identified to species level. From the 60 new records for Desertas sub-archipelago, 30 of them were also new records for Madeira Archipelago. Several specimens could not be assigned to a known species and may be new diatom species not yet described.

A new genus of Orchidaceae (Polystachyinae), <em>Isochilostachya</em>, is described. It is morphologically similar to <em>Polystachya </em>Hook. but is distinct by the narrower, grass-like leaves arranged in the upper part of the stem, long and acuminate floral bracts and sepals, and long clavate or capitate hairs densely arranged on the lip. A comprehensive description of the new genus is provided. A list of examined specimens and information about distribution, habitat, and altitude for each species are presented. A position of the members of the new genus in the cladogram recently obtained from molecular analyses of Polystachyinae is briefly discussed. A taxonomic key to Polystachyinae is included. Eleven new combinations on species level are validated. Eight lectotypes are designated. Most of the species of <em>Isochilostachya</em> are endemic to particular mountains of the Eastern Arc (Eastern Afromontane hotspot) in north-east Tanzania therefore a brief discussion about their restricted distribution is provided.

Ganoderma is an important genus of the Polyporales in the tropics. Identification of tropical species has mainly been based on morphology, which has led to misidentification. This study aimed to elucidate the diversity and phylogenetic relationships of Ganoderma isolates from different hosts in Cameroon using morphological and molecular techniques. Analyses of basidiocarp morphology and the internal transcribed spacer and mitochondria small subunit were undertaken for 28 isolates from five plant species. The results show that the isolates belong to eight species. Three of the species were identified to species level; of these only G. ryvardense has been previously described from Cameroon while G. cupreum and G. weberianum are new records. The five remaining species did not match with any previously described species and have been designated as Ganoderma with different species affinities.

The fungal genus Agaricus includes edible, medicinal and some toxic species mainly in the Agaricus sect. Xanthodermatei. As the diversity of the genus is not well known in Iran, an inventory of the species has begun in 2013 in different provinces. Morphological and/or molecular analyses of 12 selected specimens from recent field collections and from herbarium specimens revealed that ten of them belonged to four potentially poisonous species of the Agaricus sect. Xanthodermatei: A. iodosmus, A. moelleri, A. phaeolepidotus and A. xanthodermus. Moreover, our study revealed that previous first records of A. xanthodermus and A. moelleri in Iran had been based on morphologically misidentified and correctly identified specimens, respectively. Finally, three species, A. iodosmus, A. phaeolepidotus and A. xanthodermus are reported as new records for Iran mycobiota. The four species of the section are described and illustrated.
