“…However, the present study demonstrates the presence of a "van der Hammen's Organ" in the new species A. inexpectatus, whereas there are some conspicuous divergences from the Fortuynia typical scheme ( Figure 3B). Fortuynia basically shows a prodorsal anterior canal (ce) passing ventrally of the bothridium, a main lateral channel running from the dorsosejugal furrow to the ventrosejugal furrow, a short posterior canal leading to acetabulum III and a further posterior channel reaching acetabulum IV (van der Hammen 1963;Luxton 1967;Pugh et al 1990;Marshall & Pugh 2002;Krisper & Schuster 2008); in F. maculata there is an additional anterior granular groove leading above acetabulum II to acetabulum I (Pugh et al 1990(Pugh et al , p. 1533 Fig. 3).…”

Alismobates inexpectatus sp.n., found on rocky shores of the archipelago of Bermuda is described from larva to adult. Addi-tionally a detailed description of the immatures of Fortuynia atlantica, also known from Bermuda, is given. Based on adult andjuvenile morphology the position of the genus Alismobates within the family of Fortuyniidae is clearly confirmed. Furthermorethe definition of the family Fortuyniidae is revised and the classification of its members is discussed. The Fortuyniidae are bestcharacterized by the presence of a “van der Hammen’s Organ”, whereas the configuration of cuticular channels differs remark-ably between the genera Fortuynia and Alismobates. The juveniles of A. inexpectatus and F. atlantica Krisper et Schuster, 2008exhibit conformity in most aspects, whereas porose areas associated with notogastral setae and singular pores in the lateral andposterior ventral folds leading into fine tracheal tubes are documented for the first time in fortuyniid immatures. These poresare part of a complex plastron system expressed in immatures to withstand tidal inundation. The present discovery of Alismo-bates inexpectatus is the first record of a member of this genus from Atlantic coasts and therefore represents a considerable extension of the geographic distribution of this taxon.

“…For example, oribatid mites are known to have different claw morphologies adapted to their habitats: the species in the outdoor arboreal environment have three short claws that allow for mobility given unpredictable environmental changes such as wind and rain, whereas the species in the littoral environment have a single longer claw that allows for tight grip on the substrate during regular tidal flooding (Behan-Pelletier & Walter, 2000; Karasawa & Hijii, 2004;Pugh, King, & Fordy, 1990).…”

The Reciprocity of Environment and Action in Self-Righting Beetles: The Textures of the Ground and an Object, and the Claws

The process of self-righting to recover the orientation to the ground was observed in Japanese beetles. Video observation of self-righting processes in an indoor environment suggested that the properties of the environment that afforded self-righting were (a) texture of the substrate surface; (b) a soft, deformable object that can be held on to and swung by a beetle; and (c) the gap between the substrate and a hard object that afforded a spiral-like rotation of a beetle. Incorporating such properties, self-righting of beetles emerged as 3 kinds of environment-action systems: a "surface texture/leg tip system"; a "soft object held by limbs/round back on the ground system"; and a "hard object/multiple limbs/round back on the ground system." Controlled experiments on multiple individuals further revealed that what is meaningful to self-righting is not a local, discrete texture of a surface but a higher order combination of textures of surfaces surrounding the animal. Based on the results, flexibility of action, properties of the environment that afford beetles' orientation to the surroundings, and the features of the distal tip of the limbs of beetles, as well as the reciprocity among them, are discussed.

“…The nature of the occlusion is unknown, though it rapidly erodes to a uniformly flat surface in the ion mill (Young ('f al., 1993;present study), which suggests that it is a soft wax-like material. Furthermore its structure and staining characteristics resemble those of the cerotegument covering the oribatid idiosoma and van der Hammen's organ, both of which are implicated in plastron respiration (Pugh, King & Fordy, 1987c, 1990b. But, with the exception of the layer covering the major papillae in the peritrematic groove of Hofothyrus sp.…”

The respiratory system of Halarachne halichoeri (Halarachnidae: Gamasida: Anactinotrichida)

Halarachne halichoeri Allman (Halarachnidae: Anactinotrichida), a parasitic mite occuring in the nasal cavities of the grey seal, Halichoerus grypus, has an unusual apneustic respiratory system, which is described in detail. The main functions of this system are to facilitate gaseous (tracheal) respiration and prevent foreign material being forced into the tracheae under increased pressure experience when the host seal dives. Possible responses of the system to the rapidly changing pressure regimes are described.
