The work presents a comparative morphological analysis of the distinctive characteristics of the LiliaceaeJuss. family representatives, growing in the Altai Mountain Country based on the materials of Herbaria ALTB and YALT,as well as digital collections NS (NSK), MW, FRU, E, CAS, B and G. Based on the analysis of literary sources, herbariumspecimens and studies of representatives in the environment the main morphological characteristics of species, genera andfamily as a whole have been identified. For representatives of the genus Streptopus Michaux. with the rhizome type ofunderground organs, flat basal leaves and always the presence of inflorescences are common, the fruit is a berry. For somespecies of the genus Gagea Salib. small bulbs are typical, except for one-two-headed (Lilium L., Fritillaria L., TulipaL., Erythronium L. and Lloydia Salisb. ex Rchb.). The color of the corolla is different: from white and yellow to red andpurple. Yellow color of the petals is most common, white forms are less common. The genus Lilium L. is characterized bythe attachment of anthers to the threads in the middle and the presence of specks and specks on the corolla, while in therepresentatives of the remaining genera the anthers are attached with a base. Indicative spots or a checkerboard patternare also noted in the genus Fritillaria L.

Phylogenetic Lineages

The genus Microhyla Tschudi, 1838 includes 52 species and is one of the most diverse genera of the family Microhylidae, being the most species-rich taxon of the Asian subfamily Microhylinae. The recent, rapid description of numerous new species of Microhyla with complex phylogenetic relationships has made the taxonomy of the group especially challenging. Several recent phylogenetic studies suggested paraphyly of Microhyla with respect to Glyphoglossus Günther, 1869, and revealed three major phylogenetic lineages of mid-Eocene origin within this assemblage. However, comprehensive works assessing morphological variation among and within these lineages are absent. In the present study we investigate the generic taxonomy of Microhyla–Glyphoglossus assemblage based on a new phylogeny including 57 species, comparative morphological analysis of skeletons from cleared-and-stained specimens for 23 species, and detailed descriptions of generalized osteology based on volume-rendered micro-CT scans for five species–altogether representing all major lineages within the group. The results confirm three highly divergent and well-supported clades that correspond with external and osteological morphological characteristics, as well as respective geographic distribution. Accordingly, acknowledging ancient divergence between these lineages and their significant morphological differentiation, we propose to consider these three lineages as distinct genera: Microhylasensu stricto, Glyphoglossus, and a newly described genus, Nanohylagen. nov.

SUMMARYThe Renicolidae are digenean parasites of piscivorous and molluscivorous birds. Although they exhibit few morphological autapomorphies and are highly variable, the numerous suggested re-classifications within the family have never been supported by any molecular analyses. We address the possible synonymization of species within theRenicola pinguiscomplex suggested previously by Odening. We provide and analyse sequences of two nuclear (ITS2, 28S rDNA) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Renicolidae, namelyRenicola lari, Renicola pinguisandRenicola sternaesp. n., and we also provide first sequences ofRenicola sloanei. The combined molecular and comparative morphological analysis confirms the previously questioned validity of the threeRenicolaspp. of highly similar morphology, which display strict niche separation in terms of host specificity and selectivity. We identify two previously unreported clades within the genusRenicola; however, only one of them is supported by the analysis of adult worms. We also provide comparative measurements of the three examined closely related central European renicolids, and describe the newly proposed tern-specialized speciesRenicola sternaesp. n., which was previously repeatedly misidentified asRenicola paraquinta. Based on the extensive dataset collected in 1962–2015, we update the host spectrum of Renicolidae parasitizing central European birds (Renicola bretensis, R. lari, Renicola mediovitellata, R. pinguis, Renicola secundaandR. sternaesp. n.) and discuss their host-specific prevalence and intensity of infections.

Central European parasitic flatworms of the Cyclocoelidae Stossich, 1902 (Trematoda: Plagiorchiida): molecular and comparative morphological analysis suggests the reclassification of Cyclocoelum obscurum (Leidy, 1887) into the Harrahium Witenberg, 1926

SUMMARYCyclocoelidae Stossich, 1902 are medium-sized to large digenean bird parasites. Although these parasites bear few visible autapomorphic signs, and their diagnostic characters are unstable in response to the pressure applied during preparation, the numerous hitherto suggested re-classifications within the family have not been supported by any molecular analysis. We analyse here cyclocoelids found during the extensive examination of central European birds performed from 1962 to 2016, provide comparative measurements, host spectra, prevalence and intensity, and provide and analyse sequences of four DNA loci of five of the cyclocoelid species. Cyclocoleum Brandes, 1892 appears paraphyletic; thus we suggest the re-classification of Cyclocoleum obscurum (Leidy, 1887) as Harrahium obscurum (Leidy, 1887) Sitko and Heneberg comb. n. Molecular phylogenetics questioned also the validity of Cyclocoelinae Stossich, 1902 and Hyptiasminae Dollfus, 1948, which formed a single clade, whereas Allopyge Johnston, 1913, Prohyptiasmus Witenberg, 1923 and Morishitium Witenberg, 1928 formed another clade. Haematotrephinae Dollfus, 1948 are newly characterized as having a pretesticular or intertesticular ovary that forms a triangle with the testes. Analyses of non-European genera of the Cyclocoelidae and an examination of the position of families within Echinostomata La Rue, 1926 are needed.

Ikan lidah merupakan ikan ekonomis penting yang menjadi salah satu komoditas yang diperdagangkan di Tempat Pelelangan Ikan (TPI) Muara Angke. Ikan lidah memiliki keunikan karena metamorfosis mereka, kebiasaan membenamkan diri dalam substrat dan sirip pektoralnya yang terdegradasi sedangkan sirip lainnya saling bertemu. Terdapat enam spesies ikan lidah dari famili Cynoglossidae yang dapat ditemukan di Indonesia, sedangkan penelitian terkait identifikasi ikan lidah masih terbatas. Penelitian ini bertujuan untuk mengidentifikasi dan memastikan spesies ikan lidah yang diperdagangkan di TPI Muara Angke berdasarkan pengukuran morfometrik dan DNA Barcoding menggunakan sekuen COI. Hasil analisis morfologi menggunakan literatur menunjukkan bahwa ikan lidah sampel memiliki kemiripan karakteristik morfologi dengan Cynoglossus lingua dan Cynoglossus arel yang kemudian diyakini sebagai C. arel berdasarkan ciri diagnostiknya. Berdasarkan analisis DNA barcoding diperoleh spesies Cynoglossus cf. arel dengan identifikasi kesamaan 100% yang tercantum dalam GenBank. Dari hasil analisis morfologi dan DNA barcoding menunjukkan bahwa ikan lidah yang diperdagangkan di TPI Muara Angke merupakan ikan dari famili Cynoglossidae, genus Cynoglossus, spesies Cynoglossus arel.Tongue Fish Identification Traded in Muara Angke Fish Auction Based on Morphometric and DNA Barcoding Using COI Sequences. Tongue fish is an important economical fish which is one of the commodities traded at Muara Angke Fish Auction. Tongue fish are unique because of their metamorphosis, their habit of immersing themselves in the substrate, and their pectoral fins degraded while the other three fins are confluent. There are six species of tongue fish from the Cynoglossidae family that can be found in Indonesia, whereas the study about tongue fish identifications are limited. The present study aims to identify and clarify the species of tongue fish traded at Muara Angke Fish Auction based on morphometric measurements and DNA Barcoding using the COI sequence. The results of the morphological analysis using the literature showed that the tongue fish samples had similar morphological characteristics with Cynoglossus lingua and Cynoglossus arel which were then believed to be C. arel based on their diagnostic characteristics. DNA barcoding analysis of tongue fish sample shows Cynoglossus cf. arel with 100% similarity identification listed in GenBank. From the results of morphological analysis and DNA barcoding showed that the tongue fish traded at TPI Muara Angke are fish from the family Cynoglossidae, genus Cynoglossus, species of Cynoglossus arel.

The article presents the results of a comparative morphological analysis of nematodes of the species Marshallagia dentispicularis and M. sogdiana in order to determine the taxonomic position of the species in the system of the genus Marshallagia. The material was collected during dissection of abomasuses of sheep and goats in slaughterhouses in the Bukhara and Tashkent regions, as well as the city of Tashkent. A comparative analysis of the studied individuals of M.dentispicularis and M. sogdiana males found some differences in the shape and structure of the spicule and the dorsal rib. However, the length of the spicules and the dorsal rib, as well as the length and width of the body do not significantly change the range of size variations. Each species is characterized by a rather large genital bursa, there is a rudder, the shape of the lateral plate is conical in M. dentispicularis and bayonet in M. sogdiana. Taking into account some morphological similarities of certain species characteristics that are often found during dissection of animals, it can be assumed that these species are polymorphic forms of one species M. dentispicularis. The expressed doubt requires special molecular and genetic studies of the above species.

Abstract Background The Capparaceae family is commonly recognized as a caper, while Cleomaceae represents one of small flowering family within the order Brassicales. Earlier, Cleomaceae was included in the family Capparaceae; then, it was moved to a distinct family after DNA evidence. Variation in habits and a bewildering array of floral and fruit forms contributed to making Capparaceae a “trash-basket” family in which many unrelated plants were placed. Indeed, family Capparaceae and Cleomaceae are in clear need of more detailed systematic revision. Results Here, in the present study, the morphological characteristics and the ecological distribution as well as the genetic diversity analysis among the twelve species of both Capparaceae and Cleomaceae have been determined. The genetic analysis has been checked using 15 ISSR, 30 SRAP, and 18 ISTR to assess the systematic knots between the two families. In order to detect the molecular phylogeny, a comparative analysis of the three markers was performed based on the exposure of discriminating capacity, efficiency, and phylogenetic heatmap. Our results indicated that there is a morphological and ecological variation between the two families. Moreover, the molecular analysis confirmed that ISTR followed by SRAP markers has superior discriminating capacity for describing the genetic diversity and is able to simultaneously distinguish many polymorphic markers per reaction. Indeed, both the PCA and HCA data have drawn a successful annotation relationship in Capparaceae and Cleome species to evaluate whether the specific group sort individual or overlap groups. Conclusion The outcomes of the morphological and ecological characterization along with the genetic diversity indicated an insight solution thorny interspecies in Cleome and Gynandropsis genera as a distinct family (Cleomaceae) and the other genera (Capparis, Cadaba, Boscia, and Maerua) as Capparaceae. Finally, we recommended further studies to elucidate the systematic position of Dipterygium glaucum.
