“…A region's receptivity to malaria is defined by the presence, density, and longevity of local malaria vectors. Few entomological studies have been conducted in Central Brazil, and rarely in the Pantanal area, over the past decades ( Travassos 1939 , 1940a , b , Travassos 1941 , Travassos & Teixeira de Freitas 1940 , 1943 ). Recent entomological studies have been conducted in areas influenced by the construction of hydroelectric dams to determine the environmental impact caused by dam construction at Indian reservations, outside the Pantanal biome ( Ianelli et al 1998 , Gomes et al 2007 , 2010 , Ribeiro et al 2013 ).…”

BACKGROUNDStudies on malaria vectors in the Pantanal biome, Central Brazil, were conducted more than half a century ago.OBJECTIVESTo update anopheline records and assess receptivity and vulnerability to malaria transmission.METHODSFive-day anopheline collections were conducted bimonthly in Salobra, Mato Grosso do Sul state, for one year. Indoors, mosquitoes were collected from their resting places, while in open fields, they were captured using protected human-baited and horse-baited traps near the house and at the Miranda River margin, respectively. Hourly biting activity outdoors was also assessed. Secondary data were collected on the arrival of tourists, economic projects, and malaria cases.FINDINGSA total of 24,894 anophelines belonging to 13 species were caught. The main Brazilian malaria vector Anopheles darlingi was the predominant species, followed by An. triannulatus s.l. Hourly variation in anopheline biting showed three main peaks occurring at sunset, around midnight, and at sunrise, the first and last being the most prominent. The highest density of all species was recorded near the river margin and during the transition period between the rainy and early dry seasons. This coincides with the time of main influx of outsider workers and tourists, whose activities mostly occur in the open fields and frequently start before sunrise and last until sunset. Some of these individuals originate from neighbouring malaria-endemic countries and states, and are likely responsible for the recorded imported and introduced malaria cases.MAIN CONCLUSIONPantanal is a malaria-prone area in Brazil. Surveillance and anopheline control measures must be applied to avoid malaria re-emergence in the region.

Two new species of Leporinus are described from coastal rivers of southern Bahia, Brazil. One of the new species has a bright red blotch immediately dorsal to the pectoral-fin origin in life, three dark blotches along the lateral line that distinctly increase in size posteriorly, and dark longitudinal lines between scale rows on the side of body. The second new species possesses a single broad dark midlateral stripe, encompassing one or two scale rows of depth on the body and centered on the scale row below the lateral line, a dark adipose fin, and a conspicuous dark blotch on the caudal peduncle. The first new species is known only from the rio de Contas and the second from the rio das Almas and rio Jiquiriçá. In addition, Leporinus melanopleura is redescribed based on a designated lectotype and additional specimens collected in the rio Una. Leporinus melanopleura has a single broad dark midlateral stripe, encompassing one or two scale rows of depth on the body, centered on the scale row below lateral line, a hyaline adipose fin (red in life), and an inconspicuous dark blotch on the caudal peduncle.Duas espécies novas de Leporinus são descritas com base em exemplares de rios costeiros do sudeste da Bahia, Brasil. Uma das espécies novas possui uma mancha vermelho-viva imediatamente dorsal à origem da nadadeira peitoral em vida, três manchas escuras sobre a linha lateral que aumentam de tamanho para trás, e linhas escuras longitudinais entre as séries de escamas na lateral do corpo. A segunda espécie nova apresenta uma única faixa escura sobre o corpo, com altura de uma ou duas fileiras de escamas e centrada na série de escamas da linha lateral, nadadeira adiposa escura, e uma conspícua mancha escura sobre o pedúnculo caudal. A primeira espécie nova é conhecida somente do rio de Contas e a segunda dos rios das Almas e Jiquiriçá. Além disso, Leporinus melanopleura é redescrita com base no lectótipo, designado no presente trabalho, e outros exemplares coletados no rio Una. Leporinus melanopleura possui uma única faixa escura sobre o corpo, com altura de uma ou duas fileiras de escamas e centrada na série de escamas abaixo à linha lateral, nadadeira adiposa hialina (vermelha em vida), e uma mancha escura inconspícua sobre o pedúnculo caudal.
