Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay. This paper provides comments on the subspecific taxonomy and geographic distribution of Sais rosalia (Cramer, 1779) (Lepidoptera, Nymphalidae, Ithomiini), as well as an up-to-date distributional map, complemented with unpublished distributional data based on specimens deposited in the Coleção Entomológica Pe. Jesus S. Moure, Curitiba, Brazil and the Museo de Historia Natural, Lima, Peru. The following synonyms are proposed: Sais rosalia camariensis Haensch, 1905 syn. rev. as junior subjective synonym of Papilio rosalia Cramer, 1779 and Sais rosalia brasiliensis Talbot, 1928 syn. rev. as junior subjective synonym of Sais rosalia rosalinde Weymer, 1890. Additionally, the first country records of Sais rosalia in Paraguay, including the southernmost record of the species, are documented.

Aegla are endemic to southern South America and have been documented in Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay. Documentation in Paraguay is sparse, with the last published encounter occurring in 1985; in 1999, the genus was proposed extinct within that country. Since then, a few individual aeglids have been found scattered throughout the Rio Tebicuary watershed. In 2009, aeglids were discovered within the Rio Jejuí watershed within eastern Paraguay; males and ovigerous females were successfully captured including a female carrying more than 20 juveniles beneath its pleon. All individuals from the 2010 field season were later identified morphologically as Aegla platensis Schmitt, 1942. This discovery comes after a two-decade gap in abundant aeglid collections within Paraguay and serves as the first recorded breeding population of aeglid crabs to be documented. © 2012 The Crustacean Society.

The "Catalogos Sistematicos de los Vertebrados del Paraguay", published in two editions by Arnaldo de Win- kelried Bertoni (1878-1973) during the early decades of the 20th Century, represented one of the first attempts to collate in a single work the available information about Paraguayan birds. However various species listed in these works have been the subject of much debate by subsequent authors. In this paper we review the historical reports of 14 such species cited by Bertoni that were treated in later works as hypothetical, making historical reference to overlooked literature from the period and suggesting new status designations for each.

A list with comments on status, natural history, biology, hosts and distribution are presented for all species of Castniidae known from Paraguay. All the presented information has been summarized based on literature, museum specimens, infor-mation gathered from researchers/collectors and personal observations. New synonyms are proposed: Imara satrapes ca-tharina (Preiss) [= Imara satrapes (Kollar)] and Castnia juturna paraguayensis Strand (= Castnia invaria penelope Schaufuss), and synonymic lists are given in each case. Twelve species are recorded from Paraguay, four of them are re-latively common and have been previously reported from the country [Synpalamides phalaris (Fabricius), Synpalamides rubrophalaris (Houlbert), Castnia invaria penelope Schaufuss, Gazera heliconioides micha (H. Druce)]. The other eight species are much less common in collections [Imara satrapes, Castnia juturna Hopffer, Telchin licus laura (H. Druce), Ceretes marcelserres (Godart), Riechia acraeoides (Guérin-Méneville), Prometheus cochrus (Fabricius), Frostetola gramivora (Schaus), Paysandisia archon (Burmeister)]. Telchin licus laura (H. Druce) and Frostetola gramivora (Schaus) are reported from this country for the first time. Four species not known from Paraguay, but suitable to be found within, are also mentioned [Yagra fonscolombe (Godart), Castnia lecerfi Dalla Torre, Geyeria uruguayana (Burmeister), Ceretes thais (Drury)].

New distributional data are provided for 12 species of amphibian in Departamento San Pedro, Paraguay. Records are from the Reserva Natural Laguna Blanca, a small private reserve located in an area of transition from Atlantic Forest to Cerrado-type habitats. The chronic under-sampling of amphibian populations in Paraguay is highlighted. © 2012 Check List and Authors.

An old published record for "Crocodilurus" in Paraguay was almost certainly based on Dracaena paraguayensis Amaral, 1950. Thus, D. paraguayensis occurs from the Brazilian Pantanal south along the Paraguay River as far as Fuerte Olimpo, and Crocodilurus lacertinus (Daudin, 1802) remains restricted to the Amazon and Orinoco river drainages. © 2011 Check List and Authors.
