Diastylis uniplicata sp. nov. (Crustacea: Cumacea: Diastylidae) a new Korean cumacean

A new species of cumacean belonging to the genus Diastylis Say, 1818 was collected from the Nokdo Island, Korea. The new species, Diastylis uniplicata sp. nov., can be distinguished from all other Diastylis species by the combination of the smooth carapace surface with a transverse ridge and a pair of oblique ridges, and telson 1.7 times as long as pleonite 6, with 5–6 short stout simple setae laterally. Full illustrations of the new species, including the mouthparts, are given in this paper. Also, a key to the Korean species of Diastylis is provided.

Contribution to the knowledge of oribatid mites (Acari, Oribatida) of Uganda, with description of a new species of the genus Machadobelba (Machadobelbidae)

A list of identified oribatid mite taxa from Uganda, including 21 species/subspecies from 17 genera and 14 families, is presented. A new species of the family Machadobelbidae is described from leaf litter. Machadobelba ugandaensis sp. nov. differs from Machadobelba barbata Sanyal, Saha & Chakraborty, 2005 and Machadobelba dispar Balogh, 1958 by the presence of one pair of lateral teeth of the rostrum, prodorsal transverse ridge between costulae and foveolate body surface. Revised generic diagnosis and an identification key to the known species of Machadobelba are presented.

Two unusual new species of Caleremaeus (Acari: Oribatida) from eastern North America, with redescription of C. retractus and reevaluation of the genus

The oribatid mite genus Caleremaeus (Caleremaeidae) is widely distributed in the northern hemisphere but has been represented by only three extant and one fossil species. We redescribe the North American C. retractus (Banks, 1947) based on adults and nymphs; it is distinguishable from the European type species, C. monilipes (Michael, 1882) by its smaller adult size and minor differences in cuticular structure, and by the elongated, tapered form of seta h1 in nymphs. Two new species are proposed: C. nasutus n. sp. from forest soil in Alabama is unique in having adults with a large anterior rostral lobe (juveniles unknown) bearing lamellar setae; the arboreal C. arboricolus n. sp. from eastern USA and Canada is unique among described extant species in having adults with femoral saccules, a transverse ridge bearing lamellar setae and relatively large notogastral setae, and juveniles with a bothridial seta similar to that of the adult. Based on all available data, Caleremaeus is redescribed and considered the sole genus in Caleremaeidae. The higher classification of the family is reviewed, and past placement in Ameroidea is rejected in favor of the monofamilial Caleremaeoidea.

Contribution to the knowledge of the oribatid mite genus Kalloia (Acari, Oribatida, Carabodidae), with description of a new species from Indonesia

The genus Kalloia (Oribatida, Carabodidae) is recorded in the Oriental region for the first time. A new species — Kalloia gerdweigmanni n. sp. — is described from litter of oil palm plantations and jungle rubber agroforests from Sumatra, Indonesia. It differs from Kalloia simpliseta Mahunka, 1985 by the presence of a transverse ridge in the mediodistal part of the lamellae, translamella and two thick, diagonal, convergent ridges forming a triangular structure in the medioanterior part of the notogaster, and by the localization of notogastral setae da, dm, la, lm, lp and h1. The generic status of Kalloia is discussed and supported. Kalloia mahunkai Pérez-Íñigo and Baggio, 1989 and Machadocepheus foveolatus Mahunka, 1978, which were considered representatives of Kalloia, are removed from this genus and combined preliminarily in Gibbicepheus. Revised generic diagnosis and data on ecology and distribution of known species of Kalloia are presented.

EXTRACTION OF PRIMITIVES AND OBJECTS FROM HSHAPES

<p><strong>Abstract.</strong> This paper deals with 3D morphological studies of architecture surveyed with TLS to allow the modelling of a Renaissance villa in a BIM environment; the aim is to create Renaissance objects to be shaped into a parametric software and made recognizable in a BIM environment balancing level of accuracy and shortness of workflow. The approach of this study lies in the comparison of different workflows, using different BIM software and apps, useful to extract transverse ridge or primitive ribs from the point cloud of walls as vaulted ceilings, shape accurate objects, considering their level of detail and their morphological and typological aspect. The first steps of Data Processing from 3D Survey started with an accurate cleaning and transformation in appropriate but different format to be analysed into different environment and treated for a modelling phase. The different results of the different workflow have been compared to measure grade of simplification, when existent, of the single objects compared. The case study deepens the entrance of a Renaissance Villa in Tuscany, Villa di Poggio a Caiano, in its main elevation considering the vaults of porches and entrances as barrel vaults or lunette-like with double-curved nails.</p>
