Eucryptotermes Holmgren, 1911, comprises 2 species of Neotropical drywood termites with phragmotic head soldiers. We report the presence of Eucryptotermes hagenii (Müller, 1873) in native forests of the Chaco Dominion and Chaco Province, enlarging its distribution and recording the genus and species for the first time in Argentina. Eucryptotermes hagenii abundance was estimated as intermediate by standardized sampling. Eighteen morphometric characters were measured in soldiers and alates, and 9 of them provided new data. The colonies, located inside living trees trunks and dead wood, were composed of reproductives, soldiers, pseudergates, and immatures.

Abstract Albuneid crabs are specialized and active sand-burrowing organisms. Despite their substantial diversity, their ability to avoid fishing gear leads to “under collection” and a discontinuous record of distribution. The present study documents the first distributional record of Albunea occulta Boyko, 2002 from the Bay of Bengal, eastern Indian Ocean. Albunea thurstoni Henderson, 1893 is also recorded for the first time from the area, i.e., from the Gulf of Mannar, southwestern Bay of Bengal. This study further reports variation in morphological characters, especially in the carapace grooves (CG) from previous records and across specimens from different regions. Morphometric characters were found useful in species discrimination, which is explained as well.

The genus Xenoxybelis contains two species, X. argenteus and X. boulengeri, characterized by semi-arboreal habits and an extremely thin rostral area, classified in the subfamily Xenodontinae (Colubridae). Xenoxybelis boulengeri is considered a rare species and is poorly represented in scientific collections. Its external morphology is known only from the original description and seven other specimens. In this study, twenty additional specimens were examined from the Brazilian states of Acre, Amazonas and Rondônia. Variation in meristic and morphometric characters are described, and new characters are incorporated in a revised diagnosis of the species. Illustrations and a description of the hemipenes of X. boulengeri are presented for the first time. Analysis of morphological and molecular characters permit allocation of Xenoxybelis to the tribe Phylodryadini, together with Ditaxodon, Philodryas, Pseudablabes and Tropidodryas.

Boletina dispectoides Jakovlev & Penttinen sp.n., a new species of the Boletina nitida group is described. In addition, six other species of fungus gnats are reported from Finland for the first time. Manota unifurcata Lundström, 1913 was reared from dead wood. Exechia bicincta Staeger, 1840, Mycetophila forcipata Lundström, 19 13, M. sumavica (Lastovka, 1963), Trichonta tristis (Strobl, 1898) and Sciophila plarisetosa Edwards, 1921 were caught by pit-fall and Malaise traps in southern and central Finland. Detailed information on Finnish records as well as data on the general distribution of the species and their larval microhabitats is given.

SUMMARYHere we examine 3157 foxes from 6 districts of the Slovak Republic in order to determine for the first time the distribution, prevalence and identity ofMesocestodesspp. endemic to this part of central Europe. During the period 2001–2006, an average of 41·9% of foxes were found to harbourMesocestoidesinfections. Among the samples we confirmed the widespread and common occurrence ofM. litteratus(Batsch, 1786), and report the presence, for the first time, ofM. lineatus(Goeze, 1782) in the Slovak Republic, where it has a more restricted geographical range and low prevalence (7%). Using a combination of 12S rDNA, CO1 and ND1 mitochondrial gene sequences together with analysis of 13 morphometric characters, we show that the two species are genetically distinct and can be differentiated by discrete breaks in the ranges of the male and female reproductive characters, but not by the more commonly examined characters of the scolex and strobila. Estimates of interspecific divergence withinMesocestoidesranged from 9 to 18%, whereas intraspecific variation was less than 2%, and phylogenetic analyses of the data showed that despite overlapping geographical ranges, the two commonly reported European species are not closely related, withM. litteratusmore closely allied to North American isolates ofMesocestoidesthan toM. lineatus. We confirm that morphological analysis of reproductive organs can be used to reliably discriminate between these often sympatric species obtained from red foxes.

Relative growth and reproductive biology of Munida rutllanti were investigated for the first time in the Adriatic Sea. A total of 938 individuals were analysed. Sex-ratio differed statistically from the expected 1:1. Six individuals exhibited secondary sex characteristics of both males and females. Carapace length of males ranged from 10.5 to 21.5 mm, while in females it ranged from 11.2 to 19.4 mm. Sexual dimorphism was observed in seven morphometric characters. Ovigerous females were first observed in summer and later in autumn with higher frequency. Realized fecundity showed wide variation (273–3250 eggs) and positive correlation between the brood and female size. An epicaridean isopod Pleurocrypta sp., parasitizing the gill chamber of both sexes was isolated and its effect on the oogenesis was studied by histological examination of host reproductive system. Growth inhibition, modification of secondary sex characteristics, as well as retardation of oogenesis and failure of oviposition, are repercussions of bopyrid infestation. Given the small prevalence (7.85%) of the bopyrid in the M. rutllanti Adriatic population, we assume that for the moment there is no severe effect on the host population dynamic.

Summary During a survey in Iran, two known species of plant-parasitic nematodes of the families Tylenchidae and Criconematidae were reported for the first time. The morphological and morphometric characters of Iranian populations of the two recovered species are discussed and illustrated based on morphological and morphometrics data. Iranian population of Filenchus orientalis is characterized by having a 601-755μm body length, stylet length of 9.0-11.3 μm, lateral field with four incisures, tail length of 100-118 μm and males with 15-21 μm long spicules. Hemicriconemoides californianus population is characterized by having a body length of 430-550μm, lip region with two annuli, stylet length of 75-83μm and tail length of 20-28 μm. The morphological and morphometric characters of both species are in agreement with those in original descriptions.

In this contribution new rearing records of fungus gnats from poorly studied larval microhabitats are presented. From 61 species of wood growing Basidiomycete fungi, 6 species of Ascomycete fungi and slime moulds most of which had not previously been the subject of rearing studies, and from dead wood samples with fungalmyceliamade over a period of 1994–2009 in Finland and Russian Karelia, 110 species of fungus gnats were obtained, 98 of them from identified fungi. Of these for 12 species fungal hosts were formerly unknown and for 30 species larval microhabitats have been discovered for the first time. Numbers of fungus gnat species with known larval microhabitats (a total of 498 species that comprises 45.4% of the European fauna) and numbers of known fungal hosts (some 650 species of macrofungi) are calculated and categorized based on this study and previous records from Europe and East Palaearctic.
