Chemotaxonomy and flavonoid profiling of Torilis species by HPLC/ESI/MS2

The flavonoid profiles of Turkish Torilis Gaertn. (Apiaceae) species were studied by TLC, HPLC-UV and HPLC/ESI/MS² (negative mode). O-glycosides of luteolin, apigenin and chrysoeriol were identified from crude extracts with the help of mass spectra in different MS/MS modes, such as full scan, precursor ion scan and product ion scan. Luteolin-7-O-glucoside and luteolin-7-O-rutinoside were common to all species. Flavonoid profiles usually differ from one species to another and can be put to use for a genus such as Torilis which has been little studied. By the help of different flavonoid profiles, it is concluded that, the plants, which are recognised as less rayed subspecies of Torilis arvensis (Huds.) Link. in various floras including Turkish one, must be classified in species category as Torilis chrysocarpa and Torilis purpurea. Flavonoid profiles seem to be in relation with evolutionary biogeography of the species. Because the most isolated species of the genus, endemic Torilis triradiata, has the most different flavonoid pattern. Moreover, geographically isolated species, T. triradiata and Torilis leptocarpa, do not share any flavonoid except for the two which are common to all species.     

Guaiane type sesquiterpenes and other constituents from Daucus carota L.

In a chemosystematic investigation of the fruits of Daucus carota L. we have isolated eleven compounds including four guaiane type sesquiterpenes (1–4), one eudesmane type sesquiterpene (5) and six other constituents (6–11). Among them, the five compounds 1–5 all are new for Daucus carota L. and all have been reported in Torilis japonica. The results show that Daucus carota L. is chemically similar with Torilis japonica providing chemical evidence for both species used as the same traditional Chinese medicine “nanheshi”.     

Inhibitory effect of Torilis anthriscus on growth of microorganisms

Antibacterial and antifungal activities of aqueous, ethanol and ethyl acetate extract of Torilis anthriscus (L.) Gmel. (Apiaceae) were tested in vitro against ten species of bacteria and five of fungi. Antimicrobial properties were determined by disk diffusion and broth tube dilution method. In the minimum inhibitory concentrations (MICs), the ethanol extract showed the highest activity, followed by the ethyl acetate extract and the aqueous extract against bacterial species, while the extracts were inactive against the tested fungi species. The most active extract was chosen to examine the effects of its combinations with commercial antibiotics by checkerboard method. The obtained results showed that the interactions between ethanol extract/streptomycin and ethanol extract/chloramphenicol were additive and indifferent against the tested human-pathogenic bacteria. Synergism and antagonism were not observed.     

Comparative micromorphology of third instar larvae and the breeding biology of some Afrotropical Sarcophaga (Diptera: Sarcophagidae)

Four sympatric species of Sarcophaga, viz S. cruentata Meigen, S. exuberans Pandelle, S. nodosa Engel and S. tibialis Macquart, which occur in the Transvaal, South Africa, showed oviparity under optimum laboratory breeding conditions. Details of the life cycle duration under these conditions are discussed. Rearing and colonizing methods were developed. Scanning electron microscopy of third instar larvae provided useful data in distinguishing between the four species. The characters which were examined were the spinulation of the body segments and the rim surrounding the spiracular atrium of the posterior spiracles, the anterior spiracles and the spiracular hairs of the posterior spiracles.     

Biology and systematics of the New World Phyllocnistis Zeller leafminers of the avocado genus Persea (Lepidoptera, Gracillariidae)

Four New World species of Phyllocnistis Zeller are described from serpentine mines in Persea (Family Lauraceae). Phyllocnistis hyperpersea,new species, mines the upper leaf surfaces of avocado, Persea americana Mill., and red bay, Persea borbonia (L.) Spreng. and ranges over much of the southeastern United States into Central America. Phyllocnistis subpersea,new species, mines the underside and occasionally upper sides of new leaves of Persea borbonia in southeastern United States. Phyllocnistis longipalpa, new species, known only from southern Florida also mines the undersides of new leaves of Persea borbonia. Phyllocnistis perseafolia,new species, mines both leaf surfaces and possibly fruits of Persea americana in Colombia, South America. As in all known species of Phyllocnistis, the early instars are subepidermal sapfeeders in young (not fully hardened) foliage, and the final instar is an extremely specialized, nonfeeding larval form, whose primary function is to spin the silken cocoon, at the mine terminus, prior to pupation. Early stages are illustrated and described for three of the species. The unusual morphology of the pupae, particularly the frontal process of the head, is shown to be one of the most useful morphological sources of diagnostic characters for species identification of Phyllocnistis. COI barcode sequence distances are provided for the four proposed species and a fifth, undescribed species from Costa Rica.     

Chemical and principal-component analyses of the essential oils of Apioideae taxa (Apiaceae) from central Balkan

The volatile constituents of the essential oils of 23 taxa belonging to the Apioideae subfamily were studied in detail. The investigated taxa were Pimpinella serbica (Vis.) Bentham & Hooker, Libanotis montana Cr., Cnidium silaifolium (Jacq.) Simk. ssp. orientale (Boiss.) Tutin, Bupleurum praealtum L., B. sibthorpianum S. S. var. diversifolium (Roch.) Hay, Aegopodium podagraria L., Torilis anthriscus (L.) Gmel., Orlaya grandiflora (L.) Hoffm., Laserpitium siler L., Laser trilobum (L.) Brokh., Chaerophyllum aureum L., C. hirsutum L., C. temulum L., Pastinaca sativa L., P. hirsuta Pancic., Tordylium maximum L., Physospermum cornubiense (L.) DC., Peucedanum alsaticum L., P. oreoselinum (L.) Moench, P. cervaria (L.) Cuss., P. austriacum (Jacq.) Koch, P. longifolium W. et K., and P. officinale L. All of these species grow wild in the central part of the Balkan Peninsula. The essential oils were found to be complex mixtures of various compounds, more than 100 constituents being in each taxon, with contributions of main products never exceeding 25% of the total content. Sesquiterpene hydrocarbons were found to be the main group of constituents of all taxa, except for Peucedanum species, where monoterpene hydrocarbons were identified as the main components. The chemotaxonomic value of the essential-oil composition is discussed according to results of principal-component analysis (PCA). The essential-oil composition mainly reflects current taxonomic relationships between the investigated taxa.     

Taxonomic study of the planthopper genus Lacusa St?l, 1862 (Hemiptera,Fulgoromorpha, Lophopidae)

The planthopper genus Lacusa Stål, 1862 is reviewed. All species are illustrated and male genital characters are provided, and including two new species: L. digitata sp. n. and L. producta sp. n. from Yunnan Province, China. The species L. orientalis Liang, 2000 is removed from this genus based on the frons with median carina and fore femur and tibia flattened but not foliaceous. A key to species is also given. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).     

A genome-wide phylogeny and the diversification of genus Liriomyza (Diptera: Agromyzidae) inferred from anchored phylogenomics

The genus Liriomyza Mik (Diptera: Agromyzidae) is a diverse and globally distributed group of acalyptrate flies. Phylogenetic relationships among Liriomyza species have remained incompletely investigated and have never been fully addressed using molecular data. Here, we reconstruct the phylogeny of the genus Liriomyza using various phylogenetic methods (maximum likelihood, Bayesian inference, and gene tree coalescence) on target-capture-based phylogenomic datasets (nucleotides and amino acids) obtained from anchored hybrid enrichment (AHE). We have recovered tree topologies that are nearly congruent across all data types and methods, and individual clade support is strong across all phylogenetic analyses. Moreover, defined morphological species groups and clades are well-supported in our best estimates of the molecular phylogeny. Liriomyza violivora (Spencer) is a sister group to all remaining sampled Liriomyza species, and the well-known polyphagous vegetable pests [L. huidobrensis (Blanchard), L. langei Frick, L. bryoniae. (Kaltenbach), L. trifolii (Burgess), L. sativae Blanchard, and L. brassicae (Riley)]. belong to multiple clades that are not particularly closely related on the trees. Often, closely related Liriomyza species feed on distantly related host plants. We reject the hypothesis that cophylogenetic processes between Liriomyza species and their host plants drive diversification in this genus. Instead, Liriomyza exhibits a widespread pattern of major host shifts across plant taxa. Our new phylogenetic estimate for Liriomyza species provides considerable new information on the evolution of host-use patterns in this genus. In addition, it provides a framework for further study of the morphology, ecology, and diversification of these important flies.

Phylogenetic analysis of cpDNA restriction sites andrps16 intron sequences reveals relationships among Apiaceae tribes Caucalideae, Scandiceae and related taxa

Evolutionary relationships among members of Apiaceae (Umbelliferae) tribe Caucalideae Spreng. and related taxa were inferred from maximum parsimony analyses of chloroplast DNA restriction sites andrps16 intron sequences and the results compared to an existing phylogeny for the group based on nuclear ribosomal DNA internal transcribed spacer sequences. While these three data sets were not similar in size or composition, the relationships among the shared taxa, with few exceptions, were concordant. Three major lineages are recognized, coinciding with the previously delimited Scandiceae subtribes Daucinae Dumort. (Agrocharis, Ammodaucus, Cuminum, Daucus, Orlaya, Pachyctenium, Pseudorlaya), Torilidinae Dumort. (Astrodaucus, Caucalis, Glochidotheca, Lisaea, Szovitsia, Torilis, Turgenia, Yabea), and Scandicinae Tausch (Anthriscus, Kozlovia, Myrrhis, Osmorhiza, Scandix). Included in Daucinae is representation from tribe Laserpitieae (Laser, Laserpitium, Melanoselinum, Monizia, Polylophium). Daucinae and Torilidinae arise as sister taxa in the chloroplast DNA-based phylogenies, whereas in the ITS trees relationships among the three major lineages are unresolved. Unexpectedly, three species ofFerula ally with Daucinae and Torilidinae. The position ofArtedia is equivocal, occurring either sister to Daucinae in the ITS trees, within Torilidinae in the intron trees, or sister to Torilidinae upon analysis of combined ITS and intron data.Chaetosciadium trichospermum emerges withinTorilis, and is recognized asTorilis trichosperma (L.) Spreng.     

Descriptions of two new species of the botiid genus Leptobotia Bleeker, 1870 (Teleostei: Cypriniformes) from South China

Two new species of Leptobotia are here described as L. rotundilobus from the Xin'an-Jiang of the upper Qiantang-Jiang basin in both Anhui and Zhejiang Provinces and the Cao'e-Jiang in Zhejiang Province, and L. paucipinna from the Qing-Jiang of the middle Chang-Jiang basin in Hubei Province, South China. Both have a plain brown body as found in L. bellacauda Bohlen & Šlechtová, 2016, L. microphthalma Fu & Ye, 1983, L. posterodorsalis Chen & Lan, 1992 and L. tientainensis (Wu, 1930). The two new species are distinct from these species in vertebral counts, further from L. posterodorsalis in vent placement and further from the other three species in pectoral-fin length. Both differ in caudal-fin coloration and shape, and dorsal-fin location and coloration, and also in internal morphology. Their validity is confirmed by their own monophyly recovered in a phylogenetic analysis based on the mitochondrial cyt b and COI genes.     

Evolutionary relationships within the Neotropical, eusporangiate fern genus Danaea (Marattiaceae)

Genera within the eusporangiate fern family Marattiaceae have long been neglected in taxonomic and systematic studies. Here we present the first phylogenetic hypothesis of relationships within the exclusively Neotropical genus Danaea based on a sampling of 60 specimens representing 31 species from various Neotropical sites. We used DNA sequence data from three plastid regions (atpB, rbcL, and trnL-F), morphological characters from both herbarium specimens and live plants observed in the field, and geographical and ecological information to examine evolutionary patterns. Eleven representatives of five other marattioid genera (Angiopteris, Archangiopteris, Christensenia, Macroglossum, and Marattia) were used to root the topology. We identified three well-supported clades within Danaea that are consistent with morphological characters: the "leprieurii" clade (containing species traditionally associated with the name D. elliptica), the "nodosa" clade (containing all species traditionally associated with the name D. nodosa), and the "alata" clade (containing all other species). All three clades are geographically and ecologically widely distributed, but subclades within them show various distribution patterns. Our phylogenetic hypothesis provides a robust framework within which broad questions related to the morphology, taxonomy, biogeography, evolution, and ecology of these ferns can be addressed.     

Two new species of Larinus Dejean from North Africa (Coleoptera: Curculionidae), with a key to the striped Larinus (s.str.)

Two new sibling species, Larinus synthesys n. sp. from Algeria, and Larinus boroveci n. sp. from Algeria and Morocco, are described. Both species are tentatively assigned to the subgenus Larinus based on resemblance to species having longitudinal stripes on the elytra and rostrum. L. synthesys n. sp. is the smallest species in Larinus (s. str.) and is closely related to L. boroveci n. sp. The lectotype of Larinus cardopatii Lucas, 1847 is designated and redescribed. An illustrated key to the striped Larinus (s. str.) is given.     

Taxonomic study of the genus Leptopulvinaria Kanda (Hemiptera: Coccoidea: Coccidae), with a description of a new species

The genus Leptopulvinaria Kanda is revised and placed in the tribe Pulvinariini as understood by Hodgson. The species L. kawaii sp. nov., which has been misidentified as Pulvinaria camelicola or P. floccifera by several researchers, is recognized as a second species of the genus, in addition to the type species L. elaeocarpi Kanda. Adult females of L. elaeocarpi and L. kawaii are redescribed and a key to the species is presented.
