          Abstract

          The genus Alpioniscus Racovitza, 1908 ( Trichoniscidae ) from Sardinia is revised. Three new cave-dwelling species are described: A. onnisi Taiti & Argano, sp. n., A. stochi Taiti & Argano, sp. n., and A. sideralis Taiti & Argano, sp. n.. The genus Utopioniscus Schmalfuss, 2005 is considered to be a junior synonym of Alpioniscus , after morphological and molecular analyses. Alpioniscus fragilis (Budde-Lund, 1909) and A. kuehni from Grotta del Bue Marino are illustrated. With the new species, the genus Alpioniscus in Sardinia comprises six species: two troglobionts ( A. fragilis and A. onnisi ), one endogean and troglobiont ( A. thanit Taiti & Argano, 2009), and three stygobionts ( A. kuehni , A. stochi , and A. sideralis ). All the species occur in karstic areas in the central-eastern and south-eastern part of the island. A key to all the Sardinian species of Alpioniscus is provided.

            A fast GNU method to draw accurate scientific illustrations for taxonomy

            Abstract Nowadays only digital figures are accepted by the most important journals of taxonomy. These may be produced by scanning conventional drawings, made with high precision technical ink-pens, which normally use capillary cartridge and various line widths. Digital drawing techniques that use vector graphics, have already been described in literature to support scientists in drawing figures and plates for scientific illustrations; these techniques use many different software and hardware devices. The present work gives step-by-step instructions on how to make accurate line drawings with a new procedure that uses bitmap graphics with the GNU Image Manipulation Program (GIMP). This method is noteworthy: it is very accurate, producing detailed lines at the highest resolution; the raster lines appear as realistic ink-made drawings; it is faster than the traditional way of making illustrations; everyone can use this simple technique; this method is completely free as it does not use expensive and licensed software and it can be used with different operating systems. The method has been developed drawing figures of terrestrial isopods and some examples are here given.
