The Swedish species of Ophion Fabricius, 1798 are revised. More than 4800 specimens and relevant type material were studied; 234 sampled specimens produced COI sequences. The study recognises 41 species, 18 of which are described as new to science, mainly from Fennoscandian material: Ophion angularis Johansson & Cederberg sp. nov., Ophion arenarius Johansson sp. nov., Ophion autumnalis Johansson sp. nov., Ophion borealis Johansson sp. nov., Ophion broadi Johansson sp. nov., Ophion brocki Johansson sp. nov., Ophion confusus Johansson sp. nov., Ophion ellenae Johansson sp. nov., Ophion inclinans Johansson sp. nov., Ophion kallanderi Johansson sp. nov., Ophion matti Johansson sp. nov., Ophion norei Johansson sp. nov., Ophion paraparvulus Johansson sp. nov., Ophion paukkuneni Johansson sp. nov., Ophion splendens Johansson sp. nov., Ophion sylvestris Johansson sp. nov., Ophion tenuicornis Johansson sp. nov. and Ophion vardali Johansson sp. nov. Barcoding analysis also indicated the possible presence of at least three additional, partly cryptic species, but these cannot be separated morphologically with certainty at this point. Ophion costatus Ratzeburg, 1848 and Ophion artemisiae Boie, 1855 are interpreted and defined. Ophion slaviceki Kriechbaumer, 1892 is excluded from synonymy with Ophion luteus Linnaeus, 1758 stat. rev. Ophion polyguttator (Thunberg, 1824) stat. rev. and Ophion variegatus Rudow, 1883 stat. rev. are excluded from synonymy with O. obscuratus Fabricius, 1798. Ophion variegatus is redescribed and a neotype is designated. Ophion albistylus Szépligeti, 1905 (syn. nov.) is synonymized with Ophion pteridis Kriechbaumer, 1879 and Ophion frontalis Strobl, 1904 (syn. nov.) is synonymized with Ophion areolaris Brauns, 1889 syn. nov. Eleven species are reported from Sweden for the first time: Ophion artemisiae, Ophion crassicornis Brock, 1982, Ophion costatus, Ophion dispar Brauns, 1895, Ophion forticornis Morley, 1915, Ophion kevoensis Jussila, 1965, Ophion ocellaris Ulbricht, 1926, Ophion perkinsi Brock, 1982, Ophion subarcticus Hellén, 1926, Ophion variegatus Rudow, 1883 and Ophion wuestneii Kriechbaumer, 1892. The study shows that a number of species that previously have been treated as highly variable taxa, actually consist of several valid species that are separable using morphological characters. An illustrated key for the determination of the Swedish Ophion species is provided.
Eleven species of Ctenopelma Holmgren, 1857 are reported from China. Five species are new to science: C. labiatum Sheng, Sun & Li sp. nov., from Ningxia Hui Autonomous Region, C. lii Sheng, Sun & Li sp. nov., from Liaoning province, C. rufofasciatum Sheng, Sun & Li sp. nov., reared from Cephalcia lariciphila (Wachtl, 1898) from Beijing, C. pineatum Sheng, Sun & Li sp. nov., reared from Acantholyda posticalis (Matsumura, 1912) and Cephalcia lariciphila from Beijing and Henan, Shanxi, Shan’xi, Liaoning, Jilin and Heilongjiang provinces, and C. spiraculare Sheng, Sun & Li sp. nov., reared from Cephalcia lariciphila from Henan and Shanxi provinces. One species, C. nigrum Holmgren, 1857, reared from Cephalcia lariciphila in Beijing, is a new record for China. Ctenopelma tomentosum (Desvignes, 1856) was reared from Neurotoma sibirica Gussakovskij, 1935 (new host record) in Liaoning province. A key to species of Ctenopelma known in China is provided.
Neopanorpa van der Weele, 1909 is the second largest genus in Panorpidae, and over 170 Oriental species have been reported hitherto. In this paper, we describe two new species: Neopanorpa luojishana sp. nov. and Neopanorpa xingmini sp. nov. from Southwest China. We also report the first discovery of the male of Neopanorpa ocellaris (Navás, 1908) from Guangxi and Guizhou, China, a species recorded from Sikkim previously. Neopanorpa brevivalvae Chou & Wang, 1988 is synonymized with Neopanorpa lungtaushana Cheng, 1957. In addition, Neopanorpa furcula nom. nov. is proposed for Neopanorpa furcata Zhou, 2005, a junior homonym preoccupied by Neopanorpa furcata (Hardwicke, 1825). The biogeographical implications of some Neopanorpa species are discussed in brief.
Ampharete oculicirrata sp. nov. (Annelida: Ampharetidae) is described from samples collected by the Joint Nature Conservation Committee and Marine Scotland Science, in the West Shetland Shelf NCMPA in the NE Atlantic. This species is characterised by a very small body size, thin and slender paleae, twelve thoracic and eleven abdominal uncinigers, presence of eyes both in the prostomium and the pygidium, the latter provided with a pair of long lateral cirri. The external micro-morphology of the new taxon was studied using scanning electron microscopy and compared with species described or reported from the North Atlantic. Two complementary keys to all species of Ampharete in the area are also provided.
The gigas species group of the subgenus Canthidium (Neocanthidium) is defi ned and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identifi cation key and comments on the distributions of the species of the gigas group.
In the present paper three empidoid fly species new to science are described from the island Sal of the Cabo Verde archipelago. Aphrosylus salensis sp. nov., a marine dolichopodid fly, is found in the splash zone of a rocky sea shore. Crossopalpus salensis sp. nov. (Hybotidae) is recorded from two different sebkhas. Crossopalpus complicatus sp. nov. is reported from an irrigated wasteland. A key to the species of these two genera occurring on Cape Verde is provided. The presence of the morphospecies Tachytrechus tessellatus (Macquart, 1842), a presumed Old World tropical species, is confirmed.
This paper is based on three collections of Ptiliidae from Sarawak totalling more than 2000 specimens made by staff and affiliates of the Natural History Museum, London, between March–July 1978. One new genus Niptella gen. nov with its type species Niptella gutta gen. et sp. nov. and 24 new species are described and figured: Sindosium collinsi sp. nov., Bambara hammondi sp. nov., Bambara subtortuosa sp. nov., Bambara tortuosa sp. nov., Erro brookei sp. nov., Cissidium globulum sp. nov., Cissidium longum sp. nov., Cissidium marshallae sp. nov., Cissidium pauxillum sp. nov., Cissidium subfoveolatum sp. nov., Cissidium triangulum sp. nov., Discheramocephalus nigritus sp. nov., Kuschelidium sarawakense sp. nov., Ptinella alisonae sp. nov., Acrotrichis acuta sp. nov., Acrotrichis belli sp. nov., Acrotrichis bidens sp. nov., Acrotrichis geiseri sp. nov., Acrotrichis globosa sp. nov., Acrotrichis hanskii sp. nov., Acrotrichis muluensis sp. nov., Acrotrichis plaga sp. nov., Storicricha resticula sp. nov., Storicricha umbella sp. nov. New records and information are provided for Dipentium latum Darby, 2019; Ptiliola semitaria Darby, 2018; Baeocrara minima Darby, 2019; Acrotrichis agricola Darby, 2019; Acrotrichis britteni Johnson, 1969; Acrotrichis bubalis Darby, 2019; Acrotrichis cognata (Matthews, 1877) and Acrotrichis cursitans (Nietner, 1856).
This paper is part of a project of studying benthic diatom biodiversity on marine coastal regions of Sweden with focus on rare and less known species. Two new species of Cocconeis Ehrenb. are described from Vrångö, a small island in the west coast of Sweden. Both species were found as epiphytic on the green alga Ulva intestinalis L. Cocconeis magnoareolata Al-Handal, Riaux-Gob., R.Jahn & A.K.Wulff sp. nov. is a small species not exceeding 9 μm in length and characterized by having large subquadrangular areolae on the sternum valve. Cocconeis vrangoensis Al-Handal & Riaux-Gob. sp. nov. appears similar to some taxa of the 'Cocconeis scutellum complex', but differs by its stria density on both valves and variable features of the areola and valvocopula ultrastructure. Detailed descriptions based on light and electron microscopy examination, a comparison with closely related taxa, as well as a description of the habitat of both species are here presented.
Although Gastrotricha have previously been recorded in bottom sediments of greenhouses as well as in micro-reservoirs of Bromeliaceae, palm houses provide a more specific microhabitat for these animals that often originate from different regions of the world. This paper presents an investigation of gastrotrich assemblages associated with aquatic plants. Eight species of the epiphytic chaetonotids were found in the Jubilee Greenhouse of the Botanical Garden in Kraków (Poland), including three species new to science, Chaetonotus (Chaetonotus) invitatus sp. nov., C. (Hystricochaetonotus) horridus sp. nov. and C. (H.) inaequabilis sp. nov. Two other species are new to Poland, C. (C.) paucisquamatus Kisielewski, 1991 and C. (Zonochaeta) cestacanthus Balsamo, 1990, both recorded here for the first time outside their terra typica. These observations confirm that greenhouses and palm houses provide many ecological niches and favourable conditions for the development of a number of unintentionally introduced species which cannot be found outside their original climate conditions.
We present a review of Dendrocephalus (Dendrocephalinus) with an updated diagnosis for the subgenus and a key to all known species. We provide new records of Dendrocephalus alachua, which was previously supposed to be extinct, and we describe a new species, Dendrocephalus proeliator sp. nov., which is separated from all other species based on the form of the male frontal appendage. Dendrocephalus proeliator sp. nov. appears to be morphologically intermediate between D. alachua and D. lithaca. In addition, we provide conservation assessments for all four species in the subgenus, according to IUCN Red List standards. We also report for two species the first known examples of direct male-male agonistic behaviour and competition for access to areas frequented by receptive females.
