Folsomia (Collembola: Isotomidae) of China. II. heterocellata group

An annotated list of species of the Folsomia heterocellata group recorded in China is given. Folsomia cephalota n. sp., F. dorsomediaseta n. sp., F. longiseta n. sp., F. manubriopilosa n. sp., F. longdeica n. sp., and F. plenosensilla n. sp. are characterized by having a simple maxillary palp, four prelabral setae and no eyes. They differentiate mainly by characteristics of the furca. We report other species of the group which are recorded for the first time in China: Folsomia tianshanica Martynova, 1969, F. pseudovtorovi Potapov & Gulgenova, 2013, and F. pseudodecemoculata Stebaeva, 1971. This excludes F. wanxianensis Ji, Ding & Chen, 2007, for which we provide morphological remarks based on the type material. The group is mainly distributed in the central part of China (Chongqing, Gansu, southern part of Inner Mongolia, Ningxia and Shaanxi provinces). A key to all blind species with a simple maxillary palp is given.     

A review of the Malagasy endemic genus Cyrtolophus Fairmaire and description of Pseudocyrtolophus n. gen. (Coleoptera: Scarabaeidae: Rutelinae: Adoretini)

Summary

After lectotype designations for both names, the synonymy between Cyrtolophus grandicornis Fairmaire, 1895 and Cyrtolophus viduus Ohaus, 1912, n. syn., is proposed. Pseudocyrtolophus n. gen. is described to accommodate Cyrtolophus limbicollis Ohaus, 1912, its type species, and a second species, Pseudocyrtolophus australis n. sp., which is described and compared to its most related species. The lectotype of Cyrtolophus limbicollis is designated. All species are illustrated. A map showing their distribution in Madagascar is given.     

A new Indian species of Riccia L. with connections to northern Australia

Introduction. During a recent explorative field trip to the Western Ghats a new species of Riccia was discovered with possible links to the northern Australian species, Riccia caroliniana Na-Thalang.

Key Results. Morphological similarities between the new species, R. sahyadrica and R. caroliniana include the ventral positioning of the photosynthetic tissue in the ventral section of the thallus in specialised structures known as ventral lamellae. These form a v-shaped patterning along the ventral surface of the thallus and are unique to these two species. Both species also bear similar spores with differences in the micro-ornamentation. Differences between the two species also extend to sexual condition, whereby R. caroliniana is dioicous and R. sahyadrica is monoicous.

Conclusions. A new species, Riccia sahyadrica Manju & Cargill is described and illustrated and compared to the only other morphologically similar species, R. caroliniana endemic to northern Australia. Both species possess the unique characteristic of bearing ventral photosynthetic tissue in contrast to the dorsal position typically seen in all other Riccia species.

Macromitrium maolanense Zeyou Zhang,D.D.Li,Jing Yu & S.L.Guo,a new species from China based on molecular and morphological evidence

Introduction. During a field excursion in Guizhou Province, China, we collected some interesting moss specimens with branch leaves subulate in the upper part, partially and variably bistratose laminae, and a Macromitrium-like epiphytic growth habit on tree trunks. We present morphological and phylogenetic arguments for recognising these plants as a new moss species in the genus Macromitrium Brid. (Orthotrichaceae).

Methods. We compared the morphology of the potential new species with closely related species of Macromitrium, and constructed a phylogenetic tree based on ITS2, trnL and trnG including sampling from 14 other morphologically similar species of Macromitrium.

Key results. The proposed new species belongs to the genus Macromitrium (Orthotrichaceae, Musci). It is closely related to M. gymnostomum Sull. & Lesq. in the phylogenetic tree and according to gametophytic morphological features, represents a hitherto undescribed species.

Conclusions. A new moss species, Macromitrium maolanense Zeyou Zhang, D.D.Li, Jing Yu & S.L.Guo, is described and illustrated. The new species can be distinguished from all congeners by the combination of the following features of the branch leaves: (1) oblong-lanceolate, lanceolate to linear-lanceolate, gradually narrowed to an easily broken subula; (2) rather obscure upper and medial cells, often with blackish stains among cells, densely pluripapillose; (3) variably and partially bistratose laminae in the upper 1/3 portion; (4) basal cells clear, hyaline and smooth, those near costae forming a ‘cancellina region’; and (5) with numerous brownish, clavate gemmae on upper portion. We also discuss the principal distinctive characters separating the new species from its nearest congeners.     

New species of Hypolytrum Rich. (Cyperaceae) from the Neotropics

Five new species ofHypolytrum Rich. from South America are described and illustrated.Hypolytrum amorimii andH. jardimii, both of sect.Bullata T. Koyama, are species with pseudopetioles and colored leaves, and endemic to the rain forest of southeastern Brazil.Hypolytrum bahiense (sect.Hypolytrum), a species with a lax synflorescence and two, free and lightly scabridulous floral bracts, is endemic to the rain forest of southeastern Bahia, Brazil.Hypolytrum leptocalamum (sect.Hypolytrum), a species with lax synflorescence and spike ellipsoid to cylindrical, is restricted to area of tepuis in the Guayana Highland (Brazil, Guyana, and Venezuela).Hypolytrum paraense (sect.Hypolytrum), a species with three, partly connate and densely scabridulous floral bracts, is restricted to the rain forest of the Amazon Basin, in the state of Pará, Brazil.     

Two new species of Alstroemeria L. (Alstroemeriaceae) from Brazil

Alstroemeria hygrophila andA. orchidioides are both described as new from the state of Goiás (including Distrito Federal) in Brazil.Alstroemeria hygrophila is a cerrado bog-dwelling species that grows semi-epiphytically on the culms of a sedge. The vegetative stems of this species characteristically zig-zag between the pseudonodes. Like other wetlandAlstroemeria in Brazil (e.g.,A. apertiflora, A. isabellana, andA. sellowiana),A. hygrophila has wiry stems bearing narrow, lanceolate, nonresupinate leaves, and does not form root tubers.Alstroemeria orchidioides is a hysteranthus forest understory species with large vegetative leaves aggregated at the apex of the stems. The leaves on flowering stems are reduced to scarious bract-like scales. Its flowers are a pale, nearly white, greenish yellow, a color not reported in any other Brazilian species. Both species have 2n=16 chromosomes.     

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.     

Plinthus persicus n. sp. with biogeographic considerations on the P. illotus species group (Coleoptera: Curculionidae: Molytinae)

Plinthus persicus n. sp. is described; type locality: Iran, Mazandaran, 10 km SW of Rudbarak. The new species belongs to the group of Plinthus illotus, composed of some species distributed in Armenia and Transcaucasus; it expands the range of the genus to northern Iran. Some biogeographical and ecological notes are discussed. A key to the P. illotus species group is added.     

Fissidens viridulus Wahlenb. and F. minutulus Sull.

Abstract

A new species of Pseudocrossidium R.S.Williams, P. exiguum M.J.Cano &; J.A.Jiménez, is described from South America (Argentina, Brazil and Peru). The species is distinguished morphologically by its lingulate to oblong-ovate leaves, leaf marginal cells not or scarcely differentiated from inner, costa ending below apex or percurrent, and semicircular to elliptical in cross-section with two guide cells, scarcely differentiated perichaetial leaves and peristome of short and straight teeth. Drawings and light microscope photographs of the new species are provided. The principal distinctive characters that separate it from the nearest species of Pseudocrossidium and related genera are discussed.     

Seasonal Prevalence of Mosquitoes Collected from Light Traps in Gyeongsangnam Province,Republic of Korea (2013–2014)

Adult mosquito surveillance was conducted from 2013 through 2014 at four cattle sheds, a wild bird refuge, and two residential areas located in Gyeongnam Province in the Republic of Korea. Adult mosquitoes were collected in black light traps from April 1, through November 30. Mosquito surveillance was conducted to figure out population densities of vector mosquitoes, possibly invaded mosquitoes and identify various virus infections at the selected sites. A total of 107,466 females comprising 14 species and 7 genera were collected from 2013 to 2014. The most common species collected were Culex tritaeniorhynchus Giles (63.8%), Anopheles sinensis s.l. (18.9%), Aedes vexans nipponii (Theobald) (7.7%), and Culex pipiens Coquillett (5.1%). Trap indices (TIs) varied widely for species over their range, due to geographical distribution and degree of association with rural and urban communities . The most collected An. sinensis s.l. and Cx. tritaeniorhynchus appeared at a cow shed in Hapcheon (TI 347.5) and a pigsty in Daejeo‐1‐dong, Busan (TI 1,040.8), respectively, due in part to their situation near breeding sites such as rice paddies. The bi‐weekly population densities for mosquito species were variable for each of the years, apparently as a result of variable annual weather conditions. None of the mosquito species collected tested for the flavivirus including Japanese Encephalitis Virus, West Nile Virus, Dengue Virus, and Zika Virus infections by polymerase chain reaction (PCR) assay were positive.     

Two new species of Penstemon (Scrophulariaceae: sect. Saccanthera) from Nevada, U.S.A.

Two Nevada species are described here for the first time: Penstemon tiehmii N. H. Holmgren, which is endemic to Mount Lewis of the Shoshone Range in Lander County; and Penstemon rhizomatosus N. H. Holmgren, which is endemic to the central Schell Creek Range in White Pine County. They both belong to section Saccanthera and are closely related to P. kingii S. Watson, a Great Basin endemic of valley sagebrush habitats. Both new species are talus plants of higher elevations and differ from P. kingii principally in their rhizomatous habit, petiolate leaves, and pubescence of shorter hairs.

Two new species, Elaphoglossum alvaradoanum and E. pendulum, are described. The first species is endemic to Cocos Island, and the second to the mountains of Costa Rica. Elaphoglossum auripilum var. longipilosum is elevated to species rank as E. longipilosum.     

A pheromone trap for dispersal of the pathogen Zoophthora radicans Brefeld. (zygomycetes: Entomophthorales) amongst populations of the diamondback moth,Plutella xylostella L. (lepidoptera: Yponomeutidae)

A sex pheromone trap designed as a novel pathogen delivery system is described. The strategy envisaged for its use is that male Plutella xylostella moths attracted to the pheromone enter the trap and are dosed with the fungus Zoophthora radicans. After habituation to the pheromone, the moths leave the trap and disperse to the crop carrying the fungal inoculum to susceptible larvae, thus initiating or enhancing an epizootic. A fluorescent marker in the trap was used to demonstrate that moths entered and exited from the trap and carried particles to crop plants at least 5 m away. As a preliminary study, this work shows the potential of this strategy for disseminating Z. radicans in populations of P. xylostella In addition, it could be considered as a model system with implications for other pest species where a pheromone and virulent pathogen are known.     

Validation of Hygrohypnum Lindb. sect. Dilatatae Szafr.

Abstract

A number of chemical habitat parameters for the species Scorpidium scorpioides, S. cossonii and S. revolvens were investigated in three areas in northern and southern Sweden. S. revolvens occurs in a much narrower range of some parameters, especially pH and conductivity, than the other two species. When pH and conductivity are considered together, S. revolvens and S. cossonii are almost completely mutually exclusive.     

Renauldia paradoxica Allen sp. nov. (Musci,Pterobryaceae)

Abstract

Renauldia paradoxica, a new Pterobryaceous moss from western Panama, differs from all other species of Renauldia by its long, narrowly acuminate leaves. This species fits somewhat uncomfortably in Renauldia and appears to occupy a position intermediate between Renauldia, Orthostichidium, and Pterobryopsis.
