Abstract: In small samples of the siganid fishes Siganus rivulatus Forsskal et Niebuhr and S. luridus Rüppel (Teleostei) from off the Saudi coast of the Red Sea, some individuals of each fish were found infected with a new intestinal trematode. Those of S. rivulatus were infected with Hexangium saudii sp. n. (Trematoda: Microscaphidiidae), whereas those of S. luridus with Progyliauchen magnacetabulum sp. n. (Trematoda: Gyliauchenidae). Hexangium saudii sp. n. differs clearly from the two valid species of the genus, H. sigani Goto et Ozaki, 1929 (type-species) and H. brayi Hassanine et Gibson, 2005 in many specific characters and is unique in having vitelline follicles arranged in rosette-like groups and short intestinal caeca distant from the testes. Progyliauchen magnacetabulum sp. n. differs clearly from P. sigani Shalaby et Hassanine, 1997, the type and the only species of the genus in many specific characters and is unique in having a much larger ventral sucker, a very long oesophagus (longer than the total body length), a much larger oesophageal bulb and a tubular seminal vesicle.

Abstract: The holotype of Lauxania (Minettia) grandis Kertész, 1915, the representative species of an Oriental species group of the huge genus Homoneura Wulp, 1891, is redescribed and illustrated. Most of the species in this group – whose characterisation is given in the paper – have not been described. One species of this group, H. pseudograndis sp. n. is described here from Taiwan. The importance of male genitalia characters is discussed. With 15 original figures.

Key words: Diptera, Lauxaniidae, Homoneura grandis, H. pseudograndis sp. n., Taiwan

Title: The subspecies of Myotis montivagus – Taxonomic revision and species limits (Mammalia: Chiroptera: Vespertilionidae)

Abstract: A morphological evaluation of different Myotis montivagus subspecies and M. annectans is presented. Using evidence provided by cranial and dental features and multivariate statistical analyses, we raise the four montivagus subspecies to species level, recognizing M. borneoensis, M. federatus, M. montivagus and M. peytoni as distinct species. Diagnoses, distribution and ecological data are given for each of these species and the morphologically very similar M. annectans. The conservation status of M. montivagus sensu lato should be reconsidered as our elevation of these subspecies to species results in a significantly smaller distribution range for each taxon.

Title: Iridothrips iridis (Watson, 1924) (Thysanoptera: Thripidae): an unusual species of thrips that lives in a subaquatic habitat

Author: Jenser, G.

Author's address: Plant Protection Institute, Centre for Agricultural Research, Hungarian Academy of Sciences H-1525 Budapest, Pf. 102, Hungary. E-mail: jenser.gabor@gmail.com

Abstract: The leaf sheaths of Iris pseudacorus are filled with a mucous substance that provides a suitable microhabitat for populations of Iridothrips iridis to survive independently of changes of water level outside. Although the leaf sheaths remain in water all year, the population of I. iridis breeds continuously. The apterous females move into the sheaths of the young leaves at the beginning of November for overwintering. This process is a significant element in the survival strategy of I. iridis. Iris pseudacorus is an aquatic plant but it can also survive prolonged dry conditions. The populations of I. iridis are strictly associated with I. pseudacorus; they breed in the leaf sheaths and are able to survive under varying environmental conditions for many seasons.

Title: Allozyme-based genetic variability of the Daphnia atkinsoni–bolivari species complex (Cladocera: Daphniidae) in the Hungarian Great Plain

Abstract: Allozyme polymorphism investigation was performed with the aim to evaluate some population genetic characteristics of two species, Daphnia atkinsoni Baird, 1859 and Daphnia bolivari Richard, 1888 (Cladocera: Daphniidae), of temporary aquatic habitats in the Hungarian Great Plain. The analysis showed that D. bolivari is not a distinct taxon, but is nested within D. atkinsoni. At the same time, remarkable within-species differentiation was revealed in D. atkinsoni; two presumable cryptic lineages were detected by our enzyme polymorphism investigation. The separation of the lineages is mainly due to the allozyme pattern at the AAT locus. Multivariate analysis of abiotic variables of the sampling sites revealed the relation between the genetic and ecological data, pH being the relevant variable explaining 81% of the genetic variability.

Abstract: Elaborate male song may restrain competitors in various songbirds, although the exact mechanism, information content and information flow of acoustic signals are not completely understood. Here we focus on the interactions between resident and intruder males using the Eurasian Penduline Tit Remiz pendulinus. The breeding system of this small passerine bird is unusually variable including sequential polygamy by both sexes, and appears to be driven by intense sexual selection and sexual conflict over parental care. We had two objectives in this study: (i) to investigate whether male repertoire size is an intra-sexual signal in Penduline Tits, and (ii) to determine emitter and receiver roles during acoustic communication between residents and intruders. We tested these objectives in a natural population by recording the resident males' song and then challenging them by song playbacks. The residents' approach to intruder stimuli and behavioural responses were monitored. We found that intruder repertoire size did not evoke different responses by the residents. Rather, the resident's approach distance and behavioural response was predicted by his own repertoire size, suggesting that song in Penduline Tits is involved in male-male communication, and repertoire size may function as a reliable signal of the resident male's ability and willingness to defend his nest and avert possible intruders.
