AbstractTo investigate the disparity between plankton and cyst records, sediment slurry cultures were used to isolate the motile stage of dinoflagellates from Caspian Sea sediment. This has resulted in new records for this area ofKryptoperidinium foliaceum,Gymnodinium aureolumandWoloszynskiasp. and for the cyst record,Scrippsiella acuminata. TwoGonyaulaxspecies were isolated, one was identified asGonyaulax balticaand the other an unknown species. Cultures ofLingulodinium polyedrawere also isolated. The approach of using slurries was useful to provide cultures from sediments that were relatively poor in dinoflagellate cysts with contents.

The distribution of the Persian bleak, Alburnus hohenackeri Kessler, 1870 in Iran is described. During a survey from 2009 to 2012, we captured 30 specimens of A. hohenackeri from Choghakhor Wetland in Tigris River basin and Kardeh Dam in Harirud River basin of Iran. This is the first report of the occurrence of this species in these localities. The main distribution range in Iran is the southern part of the Caspian Sea from where it has been translocated to the other Iranian basins along with exotic Chinese carps.

Several epiphytic specimens of the genus Leptogium (Ach.) Gray with a foliose thallus and numerous marginal and laminal isidia collected in central and southern Spain, and previously identified as Leptogium magnussonii Degel. & P. M. Jørg., varied considerably. Two morphological forms have been differentiated: one with clusters of granulose or coralloid, aggregated isidia, identified as typical L. magnussonii and the other with clavate to dactyliform isidia as in L. subaridum P. M. Jørg. & Goward. Meanwhile, when studying the lichen L. lichenoides from some European herbaria, three epiphytic specimens belonging to L. subaridum, one from Morocco, one from Italy and the other from Greece, were identified. These new records of the latter species extend its distribution from NW America to S Europe and N Africa. In addition, mature apothecia are reported for the first time. We briefly characterize the species based on material from the new localities using the morphological and anatomical terminology proposed in Jørgensen (1994).

Azerbaijan is a nation with a Turkic population which regained its independence after the collapse of the Soviet Union in 1991. It has an area of approximately 86 000 km2. Georgia and Armenia, the other countries comprising the Transcaucasian region, border Azerbaijan to the north and west, respectively. Russia also borders the north, Iran and Turkey the south, and the Caspian Sea borders the east. The total population is about 8 million. The largest ethnic group is Azeri, comprising 90% of the population; Dagestanis comprise 3.2%, Russians 2.5%, Armenians 2% and others 2.3%.

Abstract Thirty-six species of terrestrial molluscs were found in the dry grasslands and rock outcrops of the study area, including three that were not previously known for Central Ukraine: Granaria frumentum, Pupilla bigranata and Mediterranea inopinata. These species are relics related to dry open habitats and require conservation in Ukraine on the national level, G. frumentum is already listed in the Red Book of Ukraine, and the other two should be listed in its next edition. It is proposed to create the new protected areas in the most important newly revealed locations of these species. These rocky areas also retain the high diversity of land molluscs in the region. The invasive snail Xeropicta derbentina was found for the first time on the DNIPRO Upland, on the edge of natural dry grassland. The rare native snail Morlina glabra was recorded for the first time in Kyiv Region, it is proposed to be included into the regional red list.

AbstractNew records in the Flora of Laos are presented, along with a short history of botanical collection in the country. The records are given in two lists, one relating to the Flore du Cambodge, du Laos et du Viêtnam and the other relating to the older Flore générale de l'Indochine.

The compilation of the following key has been a matter of no little difficulty, mainly owing to the close connection of the species in some of the groups, which sometimes makes it almost impossible to assign specific limits. The difficulty has in some cases been increased through the paucity of material, which prevents any adequate conception of the range of variability being obtained. This is particularly the case with some of the species coming from the Mediterranean region, which are very closely allied, and of which, as a rule, the British Museum possesses very few specimens. Names have only been sunk here as synonyms in those cases where there appeared to be no reasonable doubt, either after a comparison of the types, or of the descriptions, when these were sufficiently detailed. Eventually, therefore, it may be found that some forms which are here given specific rank will have to be regarded at most as varieties. Since so many figures of Anopheline wings, etc., have already appeared, it is not deemed necessary to add to their number. Some new records have been included, but on the other hand some old ones, which appeared to be questionable, have been omitted. As with the writer's previous papers, this key is merely intended to supplement the detailed descriptions which will be found in other works.

During a survey on Eriophyoid Mites in southwest of East Azerbaijan province (Iran), Aceria zygofabae n. sp. and Aceria alkannae n. sp. were found on Zygophyllum fabago L. (Zygophyllaceae) and Alkanna bracteosa Boiss. (Boraginaceae), respectively. They are described and illustrated here. Four further Aceria species were collected and identified as A. eucricotes (Nalepa, 1892), A. cynodonis Wilson, 1959, A. chenopodia Xue, Sadeghi & Hong, 2009 and A. tristriata (Nalepa, 1890) (protogyne and deutogyne). Aceria cynodonis is a new record for Iran Eriophyoid fauna whereas the other species were found for the first time in East Azerbaijan.

A new species of the genus Pseudechiniscus, Pseudechiniscus papillosus sp. nov., is described and figured in this paper. This new species differs from the other species of the genus Pseudechiniscus by plate sculpture that consists of many papillae-like projections. Four new records of Echiniscus species and one new record of a Pseudechiniscus species are also reported in this article: Echiniscus cheonyoungi Moon & Kim, E. melanophthalmus Bartoš, E. nepalensis Dastych, E. trisetosus Cuénot and Pseudechiniscus asper Abe Utsugi & Takeda.

Two new species of Brasineura are described from Brazil based on male specimens: Brasineura calori sp. n. (Bahia: Brazil) and Brasineura morrense sp. n. (Bahia: Brazil). They differ from the other species in the genus, in which the males are known, by hypandrium and phallosome structures. New records and comments on variation in the fore- and hind- wing venation of B. troglophilica Silva-Neto & García Aldrete and B. diamantina Silva-Neto & García Aldrete are presented. The identification key to male Brasineura species is updated.

Abstract. INTRODUCTIONDuring editorial work for the Journal of Micropalaeontology, a discussion arose between authors, reviewers and editors on the correct spelling of a technical term in palynology: ‘archeopyle’ or ‘archaeopyle’, the germination aperture in dinoflagellate cysts. One opinion was that there is only one correct spelling, namely ‘archeopyle’, with a single ‘e’ in the middle of the word, irrespective of the use of British English or American English. The other opinion was that spelling of the word should follow the language used in the rest of the text – allowing for ‘archeopyle’ with ‘e’ in American English and ‘archaeopyle’ with ‘ae’ in British English. This Notebook illustrates the reasons for this controversy and argues for the alternative spellings of the word according to American or British English spelling used.THE CAUSE OF THE ‘PROBLEM’ AND LINE OF ARGUMENTThe term ‘archeopyle’ was introduced in 1961 by William R. Evitt in one of his seminal papers on the morphology of fossil dinoflagellates, in which he recognized that many organic microfossils, then called ‘hystrichospheres’, showed a germination opening and were actually of dinoflagellate affinity. As derivation of the word he gave the following information: ‘... the presence of this opening (pyle – gate, orifice) in fossil (archeo – ancient) dinoflagellates ...’ (Evitt, 1961, p. 389). Since then, the term has become accepted and used widely by palaeontologists and biologists alike. Definitions and descriptions of the word itself and derivative terms can be looked up in the latest glossary of terminology by Williams et al. (2000). . . .
