Glanidium botocudo, new species, is described from the tributaries to the upper rio Doce and Mucuri, eastern Minas Gerais State, Brazil. It represents the northernmost record of a centromochlin catfish from the coastal rivers of the Northeastern Atlantic Forest. Glanidium botocudo is readily distinguished from its congeners, except Glanidium albescens, by the whitish grey body coloration with evenly spaced small dark brown dots. The new species has a long sharpened ventral process on the urohyal, an uncommon condition among congeners, and the lowest vertebral count among the large-sized Glanidium, 36-37. It differs from Glanidium albescensby proportional measurements and higher number of ribs. Glanidium botocudo and Glanidium albescens are probably sister... |

Parotocinclus arandai, new species of the hypoptopomatine catfish, is described from small creeks in the upper rios Jucuruçu and Buranhém basins, at the border of Brazilian States of Bahia and Minas Gerais. Parotocinclus arandai is distinguished from all congeners from the Atlantic coastal basins of southeastern and eastern Brazil, except Parotocinclus bahiensis, by having the branched rays and interradial membranes of the pectoral and pelvic fins unpigmented in ventral view. The new species is distinguished from most Parotocinclus species, by having a small eye, 14.8-19.3 mm HL (except P. maculicauda and P. planicauda) and by the presence of a tuft of hypertrophied odontodes on the supraoccipital (except P. cristatus and P. cesarpintoi). Parotocinclus... |
