The larval morphology and host of the Australian water mite Limnochares australica (Acari: Hydrachnidia: Limnocharidae) Peter MartinI and Harry Smit2 1 Zoologisches Institut, Christian-Albrechts-Universitat zu Kiel, Olshausenstr. 40, D-24098 Kiel, Germany 2 Emmastraat 43-a, 1814 DM Alkmaar, The Netherlands Abstract - The present study deals with the larval morphology and host parasite association of Limnochares (Cyclothrix) australica, a water mite from standing waters throughout Australia. The larva can be separated from the other described Limnochares spp. larvae, including the other Cyclothrix species of the area L. (L.) crinita by its unusual leg claws. The larvae of Limnochares australica were found as parasites of the water strider Tenagogerris pallidus (Gerridae, Hemiptera, Insecta). Limnochares australica is the only known Cyclothrix species parasitizing Gerridae. INTRODUCTION odontognatha Canestrini, 1884 parasitic on a The water mite Limnochares (Cyclothrix) australica water beetle. Unfortunately, his description of Lundblad, 1941a inhabits standing waters in the larva is inadequate, and the species is widespread regions of Australia. So far, the species considered a species incerta. The only Australian is known from Tasmania, Victoria, New South species of which more is known on the life cycle Wales and Western Australia (Harvey, 1990, 1998). is PhysoIimnesia australis Halik, 1940. Proctor The second author collected the species also in the (1997) reported that the larvae forgo the Northern Territory and in the Kimberley (northern parasitic stage. Hitherto, there is only one well Western Australia). Hence, it is likely that the supported host-parasite association for species occurs throughout Australia. -
Acari: Prostigmata: Parasitengona) V
Acarina 16 (1): 3–19 © ACARINA 2008 CALYPTOSTASY: ITS ROLE IN THE DEVELOPMENT AND LIFE HISTORIES OF THE PARASITENGONE MITES (ACARI: PROSTIGMATA: PARASITENGONA) V. N. Belozerov St. Petersburg State University, Biological Research Institute, Stary Peterhof, 198504, RUSSIA, e-mail: [email protected] ABSTRACT: The paper presents a review of available data on some aspects of calyptostasy, i.e. the alternation of active (normal) and calyptostasic (regressive) stages that is characteristic of the life cycles in the parasitengone mites. There are two different, non- synonymous approaches to ontogenetic and ecological peculiarities of calyptostasy in the evaluation of this phenomenon and its significance for the development and life histories of Parasitengona. The majority of acarologists suggests the analogy between the alternating calyptostasy in Acari and the metamorphic development in holometabolous insects, and considers the calyptostase as a pupa-like stage. This is controversial with the opposite view emphasizing the differences between calyptostases and pupae in regard to peculiarities of moulting events at these stages. However both approaches imply the similar, all-level organismal reorganization at them. The same twofold approach concerns the ecological importance of calyptostasy, i.e. its organizing role in the parasitengone life cycles. The main (parasitological) approach is based on an affirmation of optimizing role of calyptostasy through acceleration of development for synchronization of hatching periods in the parasitic parasitengone larvae and their hosts, while the opposite (ecophysiological) approach considers the calyptostasy as an adaptation to climate seasonality itself through retaining the ability for developmental arrests at special calyptostasic stages evoked from normal active stages as a result of the life cycle oligomerization. -
Finnish Water Mites (Acari: Hydrachnidia, Halacaroidea), the List and Distribution
Memoranda Soc. Fauna Flora Fennica 85:69–78. 2009 Finnish water mites (Acari: Hydrachnidia, Halacaroidea), the list and distribution A.M. Bagge & Pauli Bagge† A.M. Bagge, University of Jyväskylä, Open University, P.O. Box 35, FI-40014, Finland, Author for correspondence, e-mail [email protected]. The species of Finnish water mites (Acari, Hydrachidia and Halacaroidea) are listed, and their occurrence in the biogeographical provinces shown. The list is based on publica- tions, on unpublished data known by the authors, and on a private collection (of Pauli Bagge). The list consists of 139 Hydrachnidia and 9 Halacaroidea species, which are mainly limnetic or lotic. Brackish waters and the family Halacaridae have remained little studied. 1. Introduction Water mites are one of the most diversified groups of invertebrates in the freshwaters. For example the number of taxa may exceed 50 species in clean large lowland rivers of central Europe (Van der Hammen and Smit, 1996), but is lower in the northern streams (Bagge, 2001). The species and distribution of Finnish water mites have been of interest only by few researchers. The first studies have been done during expeditions of Ferdinand Koenike and Erik Nordenskiöld in the late of 19th century. The species list was later completed, among others, by professor Kaarlo Mainio Levander, who has been mentioned as ’the father of Finnish lim- nology’.

Microbiological staining was also applied to the threads to exclude their bacterial or fungal origin. The thread wall is built of fine fibrils arranged at different angles to the long axis of threads that is reflected in a certain stratification of the wall. Threads are mostly hollow or may contain electron-dense homogeneous material. No cell components are present in the thread composition. Numerous dermal glands with their small slit-like orifice scattered throughout the mite body surface are thought to produce these threads. Most probably the thread formation is a reaction of mites to stress under laboratory conditions, and this is expected to be a type of defensive reaction. -
Comparative Spermatology of Freshwater Mites (Hydrachnidia, Acari)

The sperm are aflagellate cells with magnitudes reaching 1.3 µm up to 6 µm. They are mostly oval cells, but some show an irregular shape. All investigated mites have an acrosomal complex which is composed of an acrosomal vacuole alone. An acrosomal filament is absent. This character together with a prominent field of granules, likely glycogen, may be regarded as synapomorphic of the groups forming a monophylum Hydrachnidia. All Hydrachnidia except Hydrovolzia and the Eylaoidea possess a rather large acrosomal vacuole to which a thin nuclear process attaches. This arrangement supports the taxon Euhydrachnidia. Further details shown in the fine structure of the sperm cells demonstrate the potential of these characters for the development of a better understanding of the systematic relationships within the Hydrachnidia. However, this needs further studies of more species, which should include Stygothrombioidea and observations of spermatogenesis. -

These species are distributed among 46 genera, 20 of which were new for science at the time of description. The described microsporidia parasitize about 100 hosts belonging to major groups of freshwater and terrestrial invertebrates and fish. The goal of this publication is to draw the attention of the international community to microsporidia taxa described in Russia and FSU during the era of the “iron curtain”. Many of the taxa comprising the list, are poorly known because the descriptions would be published in Russian, often in hardly available editions. The list reflects the abundance of microsporidia and breadth of their distribution among various hosts and biocenoses. We hope that publication of the list stimulates the interest of young microsporidiologists working on the territory of FSU, to the species described by their predecessors. -

An element specific to the Bukowa River was a much higher abundance of Lebertia inaequalis than in other Polish rivers. Another distinctive element was the very high numbers of Arrenurus crassicaudatus, but this taxon should be considered allochthonous – its presence in the river was due to the periodic inflowof water from fish ponds. The largest synecological group was rheophiles and rheobionts, which together accounted for 80% of the fauna. The very large quantitative share of rheobionts and rheophiles is indicative of the natural character of the river, and the physicochemical parameters confirm its good water quality. More individuals (1,764) and species (47) were caught in the lentic zone of the river than in the lotic zone (1,027 individuals, 32 species). -

(Acari, Hydrachnidia)?
Ecologica Montenegrina 27: 58-68 (2020) This journal is available online at: www.biotaxa.org/em Polyhumic dystrophic rivers - an unique habitat for water mites (Acari, Hydrachnidia)? ROBERT STRYJECKI Department of Zoology and Animal Ecology, University of Life Sciences, Akademicka 13, 20-950 Lublin, Poland. E-mail: [email protected] Received 2 December 2019 │ Accepted by V. Pešić: 3 January 2020 │ Published online 18 January 2020. Abstract Polyhumic dystrophic rivers are very rare in Poland and polyhumic rivers (both poly- and dystrophic) are weakly researched in general. The aim of the study was to present a detailed faunistic and ecological analysis of the water mites of polyhumic dystrophic rivers from Janów Forests Landscape Park (central-eastern Poland) and to compare the Hydrachnidia communities of those rivers with the Hydrachnidia of non-polyhumic rivers of this area. In small, fully polyhumic rivers Hydrachnidia fauna was poor in species and individuals, the populations of most species were very small and the characteristic feature of these rivers was very low species diversity. Therefore, the pronounced dystrophy of small polyhumic rivers should be considered a factor restricting the development of larger Hydrachnidia populations. In partially polyhumic rivers the water mite fauna was more diverse than in fully polyhumic rivers. The greater diversity of fauna resulted from the migration of species and individuals from the upper reaches of the river (non-polyhumic) and from greater habitat diversity. As a general conclusion we can say that in the fauna of polyhumic dystrophic rivers it is impossible to indicate species that could be considered characteristic of these habitats and that distinguish the Hydrachnidia communities of polyhumic rivers from those of non-polyhumic rivers.
