AbstractThe main objective of this paper is to report three benthic diatom species from the Nišava and Jerma Rivers, which prove to be new findings in the context of the Serbian diatom flora. These are also new distributional records for all three species. Monthly samples (from stones, sediments and macrophytes) were collected from May 2008 to May 2009. Diatom frustules were cleaned using chemical agents, and mounted on permanent slides. Descriptions (main valve measurement of the populations in the Nišava and Jerma Rivers), ecology, distribution in Serbia and Europe, and appropriate photomicrographs of three species are presented. Navicula novaesiberica Lange-Bertalot and Neidiomorpha binodiformis (Krammer) Lange-Bertalot & Cantonati are rarely found in Europe, while Parlibellus protracta (Grunow) Witkowski is more common. Navicula novaesiberica and Neidiomorpha binodiformis were found at higher water temperatures in comparison to temperatures reported in the existing literature. These new taxa significantly contribute to diatom floristic richness of the Nišava and Jerma Rivers in Serbia.

The main objective of this paper is to report the diatom taxa identified from the Nisava River and its tributaries, the Jerma and Temska rivers. The study area included 11 sampling sites along the Nisava River, with one site on the Jerma River and one on the Temska River. Monthly samples (from stones, sediments and macrophytes) were collected from May 2008 to May 2009. Diatom frustules were cleaned with chemical agents, and mounted on permanent slides. In total, 194 diatom taxa were identified. The most species rich genera are Navicula (25), Nitzschia (17) and Gomphonema (13), while other genera are presented with one or more species. Detailed floristic analysis of the benthic diatom flora has not been conducted before on these rivers. Therefore, this paper provides a baseline for future research.

AbstractThe main objective of this paper is to report two benthic, epilithic diatom species from the Raška River. Samples were collected in April, June, August and November 2011 and March and May 2012 from 5 localities along the Raška River by scraping off the stone surface using a brush. Diatom frustules were first cleaned using the cold acid method, and then mounted on permanent slides. Descriptions (main valve measurements of the populations in the Raška River), ecology, distribution in Serbia and Europe, and appropriate photomicrographs of two species are presented. Navicula jakovljevicii Hustedt and Navicula catalanogermanica Lange-Bertalot & Hofmann are rarely found in Europe and these are new distributional records. These new taxa significantly contribute to diatom floristic diversity of the Raška River.

The paper presents data on the composition of epilithic diatoms in the Raska River. Samples were collected by scraping stone surfaces with a brush from 5 localities along the Raska River in April, June, August and November 2011 and March and May 2012. Diatom frustules were cleaned using cold acid method, and mounted on permanent slides. An investigation of the Raska River resulted in description of 106 diatom taxa. The most species rich genera are Navicula (10), Gomphonema (10) and Nitzschia (9), while other genera are presented with one or more species. Detailed floristic analysis of the benthic diatom flora in this river has not been conducted before. Therefore, this paper provides a groundwork for future researches.

Diatom communities in the lake have an advantage of environmental assessment and paleo reconstruction study, due to the ability of diatom preserved in the sediment. There are only limited studies about taxonomy, ecology, and diversity of diatom flora in tropical areas, especially Indonesia. The main objective of the research is to describe the structure of benthic diatom communities in Pengilon Lake, together with physical chemical variables. Sediment samples were collected at an altitude of more than 2,000 msal habitats with pH around 5.40-6.86. A total of 83 diatom species identified as belonging to 16 families. The diversity index ranges from about 2.25 to 3.01 indicated the ecosystem that naturally stable with none diatom dominant. The most abundant genera were Eunotia with high diversity around 14 taxa. The composition of Eunotia assemblages was different among habitat and season variation. Eunotia has a wide tolerance of pH because of its ability to survive in an area with an acidic environment and circumneutral water. The most dominance diatom species in Pengilon Lake were Eunotia paludosa (Grunow) 39.2%, Nitzschia frustulum (Kutzing) 28.1%, Pinnularia viridis (Krammer & Lange-Bertalot) and Pinnularia divergentissima (Grunow) 24.6%.

Aunque la flora bentónica marina del Atlántico Peninsular ha sido objeto de numerosos estudios, estos nuevos hallazgos corológicos ponen en evidencia que todavía son necesarios más estudios florísticos en estas costas.English.  In this work, we provide new records and geographical distribution data for 98 seaweeds (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) inhabiting more than 80 sites (intertidal and subtidal) of the Atlantic Iberian Peninsula. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii are new records for Portugal and 5 species (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia and Derbesia marina stadium Halicystis ovalis) are new records for Galicia. Moreover, 101 new records are reported for the first time in the studied provinces (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) and 108 for the second time. Although the Atlantic marine algae of the Iberian Peninsula are well studied, these new findings show that further floristic studies are necessary to complete our knowledge of the natural heritage of this region.

A new species and eight new subspecies of Papilionoidea discovered in Vietnam between 2002 and 2020 are described and illustrated. The status of two taxa are revised. New taxa include Pieridae: Delias sanaca bidoupa Monastyrskii & Vu subspec. nov. and Talbotia naganum aurelia Monastyrskii & Vu subspec. nov.; Nymphalidae: Abrota ganga pulcheria Monastyrskii & Vu, subspec. nov.; Bassarona recta consonensis Monastyrskii & Vu, subspec. nov.; Pantoporia bieti aurantina Monastyrskii & To subspec. nov.; Ragadia latifasciata cristata Monastyrskii & Vu, subspec. nov.; Ragadia latifasciata crystallina Monastyrskii & Vu, subspec. nov.; Faunis indistincta luctus Monastyrskii & Vu subspec. nov. & Aemona gialaica Monastyrskii, K. Saito & Vu, spec. nov. The taxon infuscata Devyatkin & Monastyrskii, previously described as the subspecies Aemona tonkinensis infuscata, was elevated to the species level, while the taxon critias (Ragadia critias Riley & Godfrey) was reduced to a subspecies. Three Satyrinae species were recorded from Vietnam for the first time: Palaeonympha opalina Butler, 1871; Ypthima motschulskyi Bremer & Grey, 1853; and Ragadia latifasciata Leech, 1891.

AbstractKathirithamby, J. & Grimaldi, D.: Remarkable stasis in some Lower Tertiary parasitoids: descriptions, new records, and review of Strepsiptera in the Oligo-Miocene amber of the Dominican Republic. Ent. scand. 24: 31-41. Copenhagen, Denmark. April 1993. ISSN 0013-8711. 25-30 million years of parasite stasis is recorded in amber from the Dominican Republic, by the finding of a species of strepsipteran morphologically indistinguishable from Bohartilla melagognatha Kinzelbach, 1969 (Bohartillidae), and two species very close to Caenocholax fenyesi (Pierce 1909) (Myrmecolacidae). A new record is made of a species previously described from Dominican amber, Myrmecolax glaesi Kinzelbach, 1983. The history of the Tertiary strepsipteran fauna is discussed. Minimal ages of taxa are extrapolated based on these amber and other fossils, higher-level cladistic relationships, and fossil dating of major host groups. These new findings are consistent with Kinzelbach's hypotheses of an ancient, Lower Cretaceous/Jurassic origin of the Strepsiptera.

We report new findings of live specimens of Nassarius persicus (Martens, 1874) and N. tadjallii Moolenbeek, 2007, extending their range to the Gulf of Kachchh, Gujarat, India. The known distribution of both species was limited: N. persicus was distributed in the Persian Gulf, Gulf of Oman, and Karachi in Pakistan; N. tadjallii was reported from the Persian Gulf and the Gulf of Oman. We also provide comprehensive taxonomic descriptions of both species, along with additional morphological and ecological information.
