Resumo(s)
Deer keds (Insecta: Diptera: Hippoboscidae: Lipoptena spp.) are haematophagous ectoparasites of wild as well as domestic animals, being most often associated with cervids, but also can infest Bovidae (cattle, goats, chamois, mouflon, antelopes, etc.), and occasionally humans. Upon finding a suitable mammal host, deer keds shed their wings, remaining in a wingless form for the rest of their life. These flies are viviparous species and they generate a larvae that falls to the ground and pupates. In severe infestations, these ectoparasites can be responsible for dermatitis, allergic rhinoconjunctivitis, and in extreme cases, anaphylactic shock when they bite humans. They also potential vectors of several pathogens such as Babesia spp.,Theileria spp., Bartonella spp., Coxiella spp. and Anaplasma spp. Of over 30 species of Lipoptena insects worldwide, two of the six known species in Europe, Lipoptena cervi along with L. fortisetosa, are known to have a relatively wide distribution. We report for the first time, the presence of L. fortisetosa in a red deer (Cervus elaphus) in Castelo Branco district, in the Center of Portugal. Lipoptena fortisetosa was probably introduced in Europe with sika deer from the Eastern Palaearctic and is continuously expanding its range, especially in the Southern part of Europe. There are pertinent morphological differences between the two species, that must be taken in account to facilitate their accurate identification, among others, the external features of the head and antennae, features on the thorax, number and distribution of bristles, and in the external genitalia. This new finding may represent a new challenge to the epidemiology of this species in Portugal, and to the health of its wide range hosts, particularly because it can transmit several disease-causing pathogens to animals, as well as to humans. Further investigations are worthy of attention on Lipoptena species, in Portugal, with a One Health perspective.
