DISTRIBUTION. — Western South Africa, Indonesia and southern Japan (Kosuge & Meyer 1999). Present material, New Caledonia and Loyalty Ridge, empty shells in 347-373 m.

Holotype female (UMMZ BMOC 08- 1110 -002, # 1), 1 female paratype [strongly damaged] (UMMZ BMOC 08- 1110 -002, # 2) from Bombycilla cedrorum Vieillot (Passeriformes: Bombycillidae) (UMMZ 241853) [on head], USA: Michigan, Muskegon Co., Muskegon State game Area, along US route 31, 43.2961989 °N, 86.0668945 °W, 11 July 2008, coll. R.A. Wolinski. Type deposition. Holotype and paratype in UMMZ. Etymology. This species is dedicated to the late German acarologist, Dr. W. Fritsch author of an important early work on Harpirhynchidae. Hosts and distribution. Bombycilla cedrorum (Passeriformes: Bombycillidae) from USA (Michigan) (present paper). Differential diagnosis. Females of Crassacarus fritschi sp. nov. (males unknown) are close to those of C. sialia sp. nov. (see below) in having strongly elongated palps, four-segmented legs I and II, and two-segmented legs III. Females of these species differ from each other by the following features. In C. fritschi sp. nov., setae vF are smooth (vs. serrate in C. sialia sp. nov.), setae h 2 are 110 long (vs. 60–70), genua I and II bear one seta each (l’) (vs. without setae), leg III is with 4–6 setae (vs. 7 setae), and leg IV is with 5 setae (vs. 7 setae).Published as part of Bochkov, Andre V, Oconnor, Barry M. & Klompen, Hans, 2015, A review of the mite subfamily Harpirhynchinae (Acariformes: Harpirhynchidae) — parasites of New World birds (Aves: Neognathae), pp. 1-130 in Zootaxa 4023 (1) on pages 71-72, DOI: 10.11646/zootaxa.4023.1.1, http://zenodo.org/record/39983

Integration of Kinesthetic and Tactile Display: A Modular Design Concept
No full textFritschi M, Ernst MO, Buss M. Integration of Kinesthetic and Tactile Display: A Modular Design Concept. In: Proceedings of the EuroHaptics 2006 International Conference (EH 2006). Paris, France; 2006: 607-612.This paper describes the systematic design of a modular setup for several integrated kinesthetic and cutaneous (tactile) display configurations. The proposed modular integration of a kinesthetic display and several tactile displays in serial configuration provides a versatile experimental setup to explore the integration of the kinesthetic and tactile modality of the human perception. The kinesthetic base display is a hyper-redundant device and sufficiently powerful to carry each of the compact tactile displays. In addition to a detailed description of the partly novel displays, a series of preliminary evaluation experiments is presented
Multi-Modal VR Systems
No full textFritschi M, Esen H, Buss M, Ernst MO. Multi-Modal VR Systems. In: Siciliano B, ed. The Sense of Touch and its Rendering: Progresses in Haptics Research. Springer Tracts in Advanced Robotics. Berlin, Germany: Springer; 2008: 179-206.This chapter presents novel multi-modal and integrated systems developed in the laboratories of the Institute of Automatic Control Engineering, Technische Universita}t Mu}nchen. First, kinesthetic, tactile, visual and acoustic hardware used for multi-modal systems are introduced individually. Then the integration of the hardware into multi-modal VR systems and chosen applications are explained. The kinesthetic-tactile integrated systems are evaluated. The objective of the evaluations has been the study of the psychophysical correlation between the tactile and the kinesthetic portion of haptic information
A synrhabdosome of <i>Saetograptus fritschi</i> cf. <i>linearis</i> (Bouček) from Cornwallis Island, Arctic Canada
No full text A synrhabdosome of Saetograptus fritschi cf. linearis (Bouček) is described from mid-Ludlow strata of northwestern Cornwallis Island. The species is characterized by a sicula with a flaring aperture and dorsally projecting antivirgellar spine and by thecae with paired(?) spines or lappets. </jats:p
