We studied 18 cerambycid beetle species native to South America. Seventeen represent new state records in Brazil. Particularly, Chlorethe scabrosa Zajciw, 1963 is newly reported for the state of Rio de Janeiro with exclusion of C. brachyptera Zajciw, 1963. The Brazilian state of the type locality of Dufauxia guaicurana Lane, 1955 is fixed. Pirangoclytus mendosus (Galileo & Martins, 1996) is synonymized with P. mniszechii (Chevrolat, 1862), and its holotype is a female. Variation on Trypanidius maculatus Monné & Delfino, 1980 is commented. New country and department records for Paraguay are also provided.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

The Impact

Abstract Climatic and environmental changes, as well as human action, have been cited as potential causes for the extinction of megafauna in South America at the end of the Pleistocene. Among megamammals lineages with Holarctic origin, only horses and proboscideans went extinct in South America during this period. This study aims to understand how the spatial extent of habitats suitable for Equus neogeus and Notiomastodon platensis changed between the last glacial maximum (LGM) and the middle Holocene in order to determine the impact that climatic and environmental changes had on these taxa. We used species distribution modeling to estimate their potential extent on the continent and found that both species occupied arid and semiarid open lands during the LGM, mainly in the Pampean region of Argentina, southern and northeastern Brazil, and parts of the Andes. However, when climate conditions changed from dry and cold during the LGM to humid and warm during the middle Holocene, the areas suitable for these taxa were reduced dramatically. These results support the hypothesis that climatic changes were a driving cause of extinction of these megamammals in South America, although we cannot rule out the impact of human actions or other potential causes for their extinction.

Bat flies were surveyed between March, 2007 and February, 2008, in the Carnijó Private Natural Heritage Reserve (08° 07′ S and 35° 05′ W), an area of Atlantic Rainforest in the municipality of Moreno, in the Brazilian state of Pernambuco. Bats were captured biweekly using mist nets set during six hours each night. The ectoparasites were collected with tweezers and/or a brush wet in ethanol and stored in 70% ethanol. The specimens are deposited in the zoological reference collection of the Federal University of Mato Grosso do Sul. Sixteen species of streblid bat flies were collected from 10 bat species of the family Phyllostomidae. Thirteen of the these streblid species were recorded for the first time in Pernambuco.

The Status

The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining the status of these populations.

Archaeological Cultures

Brazilian archaeological literature has insisted for decades upon associating hunter-gatherer sites dated to the Pleistocene–Holocene transition either to the Itaparica tradition, if located in central or northeastern Brazil, or to the Umbu tradition and Humaitá tradition, if located in southern Brazil, Uruguay, or any other adjacent part of Paraguay and Argentina. These associations have been based almost entirely on the presence or absence of lesmas and “projectile points,” regardless of their morphological and technological features. In the Uruguayan archaeological literature, three other cultures are recognised: Fell industry, Catalanense industry, and Tigre tradition, all in the Uruguayan region. However, the last 10 years of systematic studies on the lithic assemblages from these sites have shown that Paleoindian societies from Eastern South America are more culturally diverse than expected and that previously defined archaeological cultures present several issues in their definition, suggesting that many of these “traditions” are not valid and should no longer be used. Instead, new lithic industries and archaeological cultures should be defined only when cultural patterns are observable through systematic analyses.

Haemagogus (Haemagogus) is restricted mostly to the Neotropical Region, including Central America, South America and islands (Arnell, 1973). Of the 24 recognized species of this subgenus, 15 occur in South America, including the Antilles. However, the centre of distribution of the genus Haemagogus is Central America, where 19 of the 28 species (including four species of the subgenus Conopostegus Zavortink [1972]) occur (Arnell, 1973).

Two eimerid coccidia are reported in a capybara (Hydrochoerus hydrochaeris) population kept in captivity in the south of Bahia, northeastern Brazil (14º 47' 57.89"S and 39º 10' 10.58" W). Oocysts of Eimeria ichiloensis are subspheroidal to ellipsoidal, 26.2 x 21.7mm with bi-layered wall, the outer yellow and sculptured and the inner, dark and smooth. Residuum is absent, but usually 2-3 polar granules are present. Sporocysts are ovoid, 12.0 x 7.6mm. Stieda body and sporocyst residuum are present. Oocysts of Eimeria trinidadensis are subspheroidal to ellipsoidal, 22.2 x 19.6mm with bi-layered wall, the outer yellow and smooth, and the inner dark and smooth. Residuum is absent, but one polar granule is present. Sporocysts are ovoid, 11.0 x 6.9mm. Stieda body and sporocyst residuum are present. Based on these descriptions and previous ones it can be concluded that these coccidea species are widely dispersed in capybaras in South America.

Dicepolia Snellen (syn. Endolophia Hampson) is revised to include thirteen species distributed in the Neotropics and Madagascar. The genus is diagnosed and differentiated from similar Neotropical Pyraloidea. The two previously described species, the type species D. roseobrunnea (Warren) (tropical South America) and D. rufitinctalis (Hampson) (Central and South America), are redescribed. Seven new species are described: D. aerealis sp. nov., D. amazonalis sp. nov., D. artoides sp. nov., D. bicolor sp. nov., D. cuiabalis sp. nov., D. vaga sp. nov. and D. venezolalis sp. nov. Four Malagasy species are transferred to Dicepolia: D. marginescriptalis (Kenrick) comb. nov., D. marionalis (Viette) comb. nov., D. munroealis (Viette) comb. nov., and D. rufeolalis (Mabille) comb. nov. Two continental African species are transferred from Endolophia to other odontiine genera: Emprepes sudanalis (Zerny) comb. nov. and Tegostoma aequifasciale (Zerny) comb. nov. D. roseobrunnea is identified as the “rosada da oiticica,” a historical seed-boring pest of Licania in northeastern Brazil; published observations of larval morphology and behavior are summarized. Habitus and genitalia of all species are illustrated, and a key to the Neotropical species is given.
