Morphometric parameters of seeds as a practical method for identifying rare species of the genus L. (Liliaceae) from East Kazakhstan region.

The genus includes some of the most important ornamental plants. The aim of this work was to study the seed morphology of species from East Kazakhstan, including seed coat structure. An analysis focused on five taxa from various natural environmental conditions.

Age-dependent variation of aedeagal morphology in Agabusuliginosus and the status of A.lotti (Coleoptera, Dytiscidae).

A doubt has arisen about the taxonomic status of within the species group due to morphological similarities and lack of molecular data. In this study, a comprehensive morphological and molecular analysis of specimens from Central Europe was conducted, focusing on the Hungarian population. Morphological comparisons of genital structures revealed age-dependent variations, suggesting a gradual transition from to .

Re-assessment of the lectotype of Brid. (≡ (Brid.) Schimp.

Re-assessment of type material of Broth. and descriptions of four new taxa (Bryophyta, Plagiotheciaceae) from Australasia.

A re-examination of the original collection of described by Brotherus in 1916 indicated that this material is not homogeneous. Re-examination of the diagnosis of this species and morphological analysis supports that two separate taxa should be distinguished - Plagiotheciumnovae-seelandiaevar.novae-seelandiae and P.

New taxa of (Plagiotheciaceae) from Pakistan.

A revision of specimens of deposited in the herbarium of Pakistan Museum of Natural History (PMNH) collected during a Japanese lead project on Cryptogams in the Western Himalaya (Pakistan) shows that the material consists of five taxa. Of the studied samples, the most common taxa were from the complex, including Plagiotheciumdenticulatumvar.obtusifolium, new to Pakistan.

Lectotypification, epitypification and history of the name Mönk. (Plagiotheciaceae).

In the protologue of , Mönkemeyer (1927) does not indicate any herbarium specimen as a type. The author only gave a short description and attached a figure illustrating selected features of this taxon. The original materials from the Mönkemeyer collection were deposited in the HBG herbarium; however, it is not currently possible to determine their location.

Contributions to the biodiversity of Vietnam - Results of VIETBIO inventory work and field training in Cuc Phuong National Park.

VIETBIO [Innovative approaches to biodiversity discovery and characterisation in Vietnam] is a bilateral German-Vietnamese research and capacity building project focusing on the development and transfer of new methods and technology towards an integrated biodiversity discovery and monitoring system for Vietnam. Dedicated field training and testing of innovative methodologies were undertaken in Cuc Phuong National Park as part and with support of the project, which led to the new biodiversity data and records made available in this article collection. VIETBIO is a collaboration between the Museum für Naturkunde Berlin - Leibniz Institute for Evolution and Biodiversity Science (MfN), the Botanic Garden and Botanical Museum, Freie Universität Berlin (BGBM) and the Vietnam National Museum of Nature (VNMN), the Institute of Ecology and Biological Resources (IEBR), the Southern Institute of Ecology (SIE), as well as the Institute of Tropical Biology (ITB); all Vietnamese institutions belong to the Vietnam Academy of Science and Technology (VAST).

Materials to the revision of the genus (Orchidaceae) in Bolivia.

The diversity of in Bolivia is evaluated. An updated key for identifying species is provided. Morphological characteristics of 15 species of Bolivian are presented together with illustrations of their floral segments.

A new species of Epeorus (Caucasiron) (Ephemeroptera, Heptageniidae) from Azerbaijan and Iran.

A new species, Epeorus (Caucasiron) hyrcanicus, is described based on larval morphology and molecular data (COI) containing sequences from all Caucasian species described to date. The species is distributed in the Hyrcanian forest of southeastern Azerbaijan and northwestern Iran. Based on our wide-range sampling, the new species is likely endemic to this area.

First fossil record of the mayfly family Vietnamellidae (Insecta, Ephemeroptera) from Burmese Amber confirms its Oriental origin and gives new insights into its evolution.

The small, monophyletic mayfly family Vietnamellidae Allen, 1984 has so far only been known from a few extant species of the genus Tshernova, 1972, which are all distributed in the Oriental Realm (Vietnam, Thailand, China, and India). Herein we report the first fossil record of Vietnamellidae based on a male and female imago from Mid-Cretaceous Burmese amber. We establish the new genus to accommodate these two new Mesozoic specimens.

Lectotypification of , a Hawaiian synonym of (Plagiotheciaceae).

In 2020, Broth. was recognised as a synonym of Lindb.; however, due to the inability to compare all known original material, the conducted taxonomic analysis was not completed with lectotypification of the name.

Tiger beetles (Coleoptera, Cicindelidae) of Northern Mindanao region (Philippines): checklist, distributional maps, and habitats.

The knowledge about tiger beetle fauna of the Northern Mindanao region (Philippines) is summarized based on literature data and new records. Thirty species classified in ten genera (, , , , , , , , , and ) were documented from the area (56% of tiger beetle fauna of Mindanao and 21% of Philippine species). Twelve species were noted from Northern Mindanao region for the first time, including five taxa, , , , , and , not recorded from Mindanao before.

Achene micromorphology and its taxonomic significance in some species in sect. (Asteraceae).

The genus is one of the largest and taxonomically most complicated apomictic genera. Currently, it is considered to consist of over 2800 species placed within 60 sections. Due to the large number of species, and their uniform morphological design and plasticity of leaves, the identification of plants at the species level is challenging even for specialists.

was first described in 1927 by V.F. Brotherus, based on materials from Hawaii.

Diversity and distribution of Epeorus (Caucasiron) (Ephemeroptera, Heptageniidae) in Iran, with descriptions of three new species.

Combining morphological and molecular data in an integrative approach, three new mayfly species of Epeorus (Caucasiron) are described. These include Epeorus (Caucasiron) alborzicus Hrivniak & Sroka, and Epeorus (Caucasiron) shargi Hrivniak & Sroka, from northern Iran, and Epeorus (Caucasiron) zagrosicus Hrivniak & Sroka, from central Iran. They are unambiguously delimited using both distance-based and likelihood-based approaches in the analyses of barcode COI sequences.

Nomenclatural changes in Braasch & Soldán, 1980 (Ephemeroptera, Baetidae).

The genus Braasch & Soldán, 1980 is accepted here in a wide sense, i.e., including Waltz & McCafferty, 1987.

Morphology and secondary chemistry in species recognition of group - evidence from molecular data with notes on the ecological niche modelling and genetic variability of photobionts.

To evaluate the importance of morphological and chemical characters used in the recognition of species within the group, we performed phylogenetic, morphological and chemical analyses of 335 specimens, of which 34 were used for molecular analyses. Phylogenetic analyses, based on ITS rDNA sequences, show that is distinct from and the most important difference between those species is the development of pseudocyphellae. In , they are mostly marginal and form white rims along lobes margins, but laminal pseudocyphellae can develop in older parts of thalli and are predominantly connected with marginal pseudocyphellae.

Revision of fossil Metretopodidae (Insecta, Ephemeroptera) in Baltic amber - Part 4: Description of two new species of Clemens, 1915, with notes on the new species group and with key to fossil male adults of .

The species group is established here for three extinct species, namely for the earlier described Demoulin, 1968, and for two new species from Eocene Baltic amber, and Based on the well-preserved specimens of these species, a diagnosis is provided for the newly established species group. Representatives of the species group are characterized by the presence of large, medially contiguous eyes, stout pointed setae along the outer margin of the foretibia, three intercalaries in the cubital field of the forewing, and elongated penis lobes, which are apically triangular or rounded, medially contiguous, and with a V-shaped cleft apically. Further new specimens of the species group are documented that cannot be attributed to species level due to their poor preservation.

New Oligoneuriidae (Insecta, Ephemeroptera) from Iran.

Two new species of the mayfly family Oligoneuriidae are described based on larval specimens recently collected in Iran. The first new species, Godunko & Staniczek, , can be distinguished from all its congeners by the presence of pronounced protuberances posteromedially on abdominal terga, highly reduced paracercus, large lamella of gill I, and setation on hind margin of middle and hind femora confined to their basal halves. The second species, Bojková, Godunko, & Staniczek, , remarkably belongs to a mostly Afrotropical genus.
