| Seven new species of Trichorhina Budde-Lund, 1908 are described, six from Southeastern Brazil, T. biumbonata sp. nov., T. lenkoi sp. nov., T. myrmecophila sp. nov., T. orensis sp. nov., T. sexdens sp. nov., T. tropidocerata sp. nov., and one from Central Brazil, T. crassisetae sp. nov. An emended diagnosis for the genus and a key to the 19 species recorded from Brazil are provided. Trichorhina acuta Araújo & Buckup, 1994 is recorded to state of Mato Grosso do Sul. |

| ABSTRACT Balloniscus glaber Araujo & Zardo, 1995 (Balloniscidae), a Neotropical Oniscidea, has been recorded historically in environments with low or no human interference. In one of these areas, it was determined as aK-strategist. Recently, however, this species was documented in a disturbed forest within urban limits. The present work revealed that the population in the urban area has high density, high number of ovigerous females and mancae in the population, a long reproductive period, and early sexual maturity. These results suggest that modified environments may provide favorable conditions and that the species is not negatively affected by human influence. |

| We analysed species abundance and composition during one year of sampling at Itapuã State Park, a conservation unit in the State of Rio Grande do Sul, southern Brazil. Samples were collected monthly from May 2003 to April 2004 along a 4 km forest trail divided in three transects along the slopes of a small hill. Terrestrial isopods were hand searched by three people for 40 minutes at two sampling sites along each transect, summing 240 minutes of sampling effort per transect per month. Six species distributed in six families were found. The collector curve stabilised when half the samples were taken, demonstrating sampling sufficiency: analytical estimates did not predict more species to be found in the trail. Atlantoscia floridana (van Name, 1940) was... |

| The genus Benthana includes 25 species with distribution in Brazil and Paraguay. In this paper we describe a new species from the state of Santa Catarina, southern Brazil, and provide new records for Benthana cairensis Sokolowicz, Araujo & Boelter, 2008, Benthana longicornis Verhoeff, 1941, Benthana moreirai Lemos de Castro, 1985, Benthana picta (Brandt, 1833), Benthana serrana Araujo & Lopes, 2003, and Benthana taeniata Araujo & Buckup, 1994. |

| Based on field data, this study presents the growth curve of Balloniscus glaber Araujo & Zardo, 1995, a terrestrial isopod species found in Parque Estadual de Itapuã (PEI), Rio Grande do Sul, Brazil. Specimens were monthly sampled, from May 2004 to April 2005, at PEI. Captured individuals were sexed, their cephalothorax width was measured, and the growth curve was described according to von Bertalanffy's model. Male and female growth curves are described by the equations: Wt = 2.256[1-e-0.00394(t+91.128)] and Wt = 2.588[1-e-0.00301(t+101)], respectively. Curves show differential growth between males and females, with females reaching higher W<FONT FACE=Symbol>¥</FONT>, and a slower growth rate than males. Based on theses curves, life... |
