A new species of Neotropical freshwater stingray of the genus Potamotrygon Garman, 1877 from the Río Madrede Díos, Peru (Chondrichthyes: Potamotrygonidae)

Potamotrygon tatianae sp. nov., is described from Río Madre de Díos, Peru, upper Rio Madeira basin. The new species is distinguished from all congeners by a unique combination of characters, including its dorsal color pattern formed by a relatively slender, highly convoluted, beige to dark brown vermicular pattern, a single row of dorsal tail spines, and a relatively longer tail posterior to caudal stings. Potamotrygon tatianae sp. nov., occurs sympatrically with other species of Potamotrygon (P. falkneri, P. orbignyi and P. motoro). From the similar species P. falkneri, P. tatianae sp. nov., is further distinguished by the absence of circular, reniform, and oval spots, by its proportionally much longer tail, by having dorsal tail spines in one irregular row, and by features of the ventral lateral-line canal, dermal denticles and neurocranium. From P. orbignyi, the new species is distinct by lacking a reticulate pattern on dorsal disc and by the presence of two angular cartilages. From P. motoro, P. tatianae sp. nov., is further separated by the lack of ocelli formed by strong black concentric rings, by the more flattened aspect of its head and disc, and by having smaller and more numerous teeth. The discovery of a new species that so closely resembles a congeneric form in color pattern, a feature highly variable within the latter, highlights the importance of examining large series of individuals and of detailed morphological analyses in revealing the potentially highly cryptic nature of the diversity within the family.

Three species of Pycnadenoides Yamaguti, 1938 (Digenea: Opecoelidae), including two new species from temperate marine fishes of Australia

Pycnadenoides pagrosomi Yamaguti, 1938 and P. reversati n. sp. from Pagrus auratus (Sparidae) and P. invenustus n. sp. from Nemadactylus valenciennesi (Cheilodactylidae) are described from the temperate marine waters off south-west Western Australia and south-east Queensland. The difference in the anterior extent of the vitelline follicles observed in P. reversati n. sp. recovered from off south-east Queensland waters and the material from off Western Australia is discussed. P. reversati n. sp. is distinguished from P. pagrosomi mainly in the position of the genital pore and in the arrangement of the testes, and from P. invenustus n. sp. in the posterior extent of the cirrus-sac. P. reversati belongs to the group of species with a short cirrus-sac and P. invenustus to the group with the cirrus-sac reaching into the anterior hindbody.

Beyond time and oblivion : Sir Robert Sidney’s autograph manuscript

Dealing with ancient manuscript or old printed texts often constitutes a difficult task, especially to philologists and editors, for two main reasons: the precarious state of preservation of the documents and the uncertainty regarding their origin, authenticity and authorship. These problems are aggravated by spurious versions, due to the publication of truncated works, poorly supervised miscellanies and non-authorised editions. Sir Robert Sidney’s literary text constitutes an exception amidst such vicissitudes, once the original corpus is wholly contained in a notebook exhibiting the organisation and unity conceived by the author himself. Today, there is no evidence that any loose poems, either autograph or copied by amanuenses, were in circulation among members of the Elizabethan court society. The notebook was kept in private collections for four centuries, which probably explains why it was so well preserved. In fact, only in 1984 would P.J. Croft’s fine edition bring the youngest Sidney’s Poems into light. In this work, I approach Croft’s perceptive, accurate philological study that eventually rescued from oblivion a remarkable piece both of the Elizabethan lyric poetry and of the English Renaissance, and, at the same time, look into Robert Sidney’s peculiar, careful and original formatting of his own autograph manuscript.

Sir Walter Raleigh and Guiana : a mysterious search, a metaphorical discovery

The essay analises Sir Walter Raleigh's report (1595) of his search for Guiana, as well as his reflection on the New World and its inhabitants, which is, in many aspects, different from his contemporaries.

SIR performance evaluation of MB-OFDM UWB system with residual timing offset

Signal-to-interference ratio (SIR) performance of a multiband orthogonal frequency division multiplexing ultra-wideband system with residual timing offset is investigated. To do so, an exact mathematical derivation of the SIR of this system is derived. It becomes obvious that, unlike a cyclic prefixing based system, a zero padding based system is sensitive to residual timing offset.
