A New Species

Xyliphius anachoretes, a new species of aspredinid catfish is described from the Tocantins-Araguaia River system. Xyliphius anachoretes is diagnosed by the presence of six developed retrorse serrae on posterior border of pectoral-fin spine, presence of papillae on the lower lip bearing minute branches, and only two dorsal procurrent rays. Comments about the informativeness of character-state variation among Xyliphius species and aspredinid related genera are furnished. Also, a brief discussion about conservation status of the new taxon is made.

A New Species

The bibliography of a hitherto inaccurately described anonymous eighteenth-century popular German work on natural history is given, dealing with mammals, birds, fishes, amphibians and reptiles. As an addendum to this work the publisher has given an engraving of an unknown fish from the river Lech, river system of the Upper Danube. The fish could be identified as the cyprinid Leuciscus meidingeri Heckel, 1852. The observation of the species was made 66 years before its recognition as a new species by Heckel.

A New Species

A new species of the genus Miroblatta Shelford, 1906 is described from caves of Borneo in East Kalimantan, Indonesia. This new species, M. baai sp. nov., is similar to the epigean species M. petrophila Shelford, 1906 also found in Borneo. It differs by a larger adult size, longer legs, shorter wings, longer pronotum showing a remarkable central bulbous structure, lighter colouration and genital morphology (especially sclerite L1 shape). The genital morphology as well as morphological evidence for ovoviviparity confirm that the genus belongs to the family Blaberidae, subfamily Epilamprinae. Contrary to its epigean relative M. petrophila, this new species has been found exclusively in karstic caves of the same underground river system and these occurrences as well as the elongated legs and reduced eyes allow one to assume that this is a truly troglobitic species, so far the first one recorded in the family Blaberidae.

AbstractAs part of a preimpoundment baseline study in the James Bay Hydroelectric Project in Northwestern Québec, systematic collections of aquatic insects were made in 1974 and 1975 in lakes and streams of the Rivière du Castor drainage. The aquatic Empididae are reported on here: they comprise 12 species, one of which is new (Hemerodromia fibrina n. sp.). Except for the boreal Metachela albipes, the fauna is remarkably temperate in character and composition. Emergence patterns are similar, though foreshortened, to those observed in southern Québec, and there are no bivoltine species. Most species are lotic and many thrive in fast waters (Neoplasm scapularis, Roederiodes recurvatus), but there is nevertheless a distinct lacustrine fauna (H. fibrina and perhaps also Chelifera rastrifera). The bog stations harbored only the widespread Chelifera palloris.
