A new species, Tagalis drakkar n. sp., is described from Misiones, Argentina. It is easily separated from the other species of the genus by the particular shape of the median process of the pygophore and other male genitalic structures, and the overall pale coloration. We also describe the male aedeagus of Tagalis femorata Melo (2008) and discuss the affinities of the two species studied in the context of species groups proposed by Castro-Huertas and Forero (2014).
A new species of Cosmoclopius Stål, 1866, C. joceliae sp. nov. is described based on specimens collected in northern Argentina. This new species is recognized by the vertical and truncate median process of pygophore, and the short-recurved spine on the apex of the dorsal phallothecal sclerite; and other features such as the dorsally black head, pronotum, and femora, and the thoracic sterna black with median pale markings; some females show lighter posterior pronotal lobe and femora with more conspicuous dark and pale bands. Digital images of the adult male and female and male genitalia are provided, as well as a comparison with the species of the genus are given.
SELF-AGGRESSIVE behaviour is a serious and common problem in non-human primates kept in laboratory facilities and zoos (Reinhardt and Rossell 2001), particularly in highly intelligent Old World primates (Dickie 1998). The aetiology appears to be multifactorial, but it occurs frequently as a reaction to a distressing situation such as a new arrival, separation, isolation or husbandry changes (Dickie 1998). This short communication describes the treatment of acute selfaggressive behaviour in a captive western lowland gorilla (Gorilla gorilla gorilla). A 16-year-old female western lowland gorilla presented with an acute onset of anorexia, depression, vomiting and diarrhoea. Faecal culture showed a heavy growth of Salmonella enterica serovar Enteritides. To administer treatment, it was necessary to separate the animal from its group, including its four-year-old cub, and to use a remote delivery injection system daily for 12 days. After 10 days of treatment, when the initial condition was
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
