This inventory intends to provide updated numbers of vascular plants occurring in Cyprus. Currently, 1649 indigenous taxa (species and subspecies) are known to occur in Cyprus. In addition 254 taxa belong to various categories of neophytes. The endemism rate of the indigenous flora amounts to 8.55 %, i. e. 141 taxa, while 33 species and subspecies belong to the category of near-endemic for which Cyprus bears significant responsibility for their conservation.
New data on Odonata of the Preah Sihanouk Province of Cambodia obtained in March 2017 and November 2018 are presented. The presence of Onychargia atrocyana Selys, 1865 in Cambodia is confirmed. Twentyone species are added to the known fauna of the Kbal Chhay Waterfall environs, 19 species to that of Ream Peninsula and 4 to that of Koh Rong Island. The total number of species registered for Kampong Saom Peninsula amounts to 74. The presented data are rather of historical importance since most of the remaining forest has been quickly and irreversibly logged a few months ago. The validity of Gynacantha demeter Ris, 1911 as a species distinct from G. dohrnii Krüger, 1899 is doubted.
In this paper we describe two new tardigrade species belonging to the Macrobiotus hufelandi complex: Macrobiotus noongaris sp. nov. from Perth, Australia, and Macrobiotus kamilae sp. nov. from Mussoorie, India. Live specimens extracted from moss samples were used to establish laboratory cultures in order to obtain additional animals and eggs needed for their integrative descriptions. These descriptions are based on traditional morphological and morphometric data collected using both light and scanning electron microscopy, which, at the same time, were associated with DNA sequences of four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI). The use of DNA sequences allowed for a more accurate verification of the taxonomic status of M. noongaris sp. nov. and M. kamilae sp. nov as independent species of the hufelandi group. Although they both exhibit typical inverted goblet-shaped processes, they represent a recently discovered clade, which was thought to group species with modified morphology of egg processes. Thus, this contribution expands the definition of the mentioned clade and constitutes another link that will be helpful for future studies on the evolution of the M. hufelandi complex.
Two new species of the genus Lepidocyrtus Bourlet, 1839 from southern China are described here: L. (Acrocyrtus) huizhouensis sp. nov. from Guangdong Province and L. (Setogaster) wanningensis sp. nov. from Hainan Province. Lepidocytus (Acrocyrtus) huizhouensis sp. nov. is the fourth species of the subgenus reported from China and L. (Setogaster) wanningensis sp. nov. is the first report of the subgenus from China.
This study was conducted to describe and illustrate two new species of groundwater amphipods from the northern parts of the Zagros Mountains in West Azerbaijan Province, Iran. Mitochondrial (COI) and nuclear (28S rDNA) fragments as well as several morphological traits were used to characterize Niphargus urmiensis sp. nov. and Niphargus fiseri sp. nov. The phylogenetic analyses showed that the nucleotide differences between the recently described species and their close allies are attributed to their distinctiveness. The molecular analysis also introduced that the new species are placed within the clade comprising Iranian species as a sister taxon. The genetic distances between N. urmiensis sp. nov. and N. fiseri sp. nov. are 7.6% and 1.6%, respectively based on the COI and 28S rDNA gene fragments.
Cave research in Hungary has developed a lot in the last decade. As a part of this progress, enchytraeid specimens were collected from Hungarian caves and were subsequently characterized by comparative morphological and molecular taxonomic analyses. Molecular phylogenetic studies based on ITS, CO1 and H3 sequences and morphological results confirmed that these specimens represented two species new to science. The descriptions of Fridericia baradlana sp. nov. and Fridericia spelaeophila sp. nov. are presented in this paper.
Two new species of the leucopholine genera Engertia Dalla Torre, 1913 and Philacelota Heller, 1900 are described. Engertia allolepis sp. nov. from Ambon Island in the Moluccas, Indonesia, can be distinguished from the other species of the genus by the heterogeneous setosity on the elytra as well as by a very robust and arcuate aedeagus. Philacelota leucothea sp. nov. from Luzon Island, Philippines, differs from the other species of Philacelota in the scaled whitish vestiture of the pronotum and elytra, as well as in the unidentate protibiae and in the shape of parameres. The length of the 3rd antennomere is the only reliable character for the separation of the genera Engertia and Philacelota. A revised dichotomous key for identification of males and females of all species of Engertia and Philacelota is given. The genus Philacelota is reported from the Philippines for the first time.
Two new nematode species of the genus Tobrilus Andrássy, 1959 from Lake Baikal are described and illustrated. The first species Tobrilus elginus sp. nov. was found in the littoral zone of Maloye More Bays. The second species Tobrilus juliae sp. nov. dwells on bodies of dead sponges Lubomirskia baicalensis (Pallas, 1776). Tobrilus elginus sp. nov. is most similar to T. amabilis Tsalolikhin, 1974 and T. bekmanae Tsalolikhin, 1975. In contrast to the first species it has a shorter body and spicules, longer gubernaculum and a shorter supplements row. Its body is shorter and thinner, tail and supplement row are shorter and the vulva is more posterior as compared to the second species. The body size of Tobrilus juliae sp. nov. is most similar to T. securus Gagarin & Naumova, 2011 and T. saprophagus Naumova & Gagarin, 2017. From the first of these species it differs by the thinner body, shorter tail, comparatively shorter outer labial setae and shorter spicules. It differs from the second species by a thinner body, shorter male tail and shorter labial setae.
