Purpose Larval stages of trombiculid mites infest a wide variety of wild and domestic animals. The most common clinical
signs related with the presence of these parasites are alopecia, crusts, erythema, excoriation, erosion, papules, pustules and
vesicles. Most of trombiculid infestations may not be perceived by the clinician due to their small size.
Although Ericotrombidium ibericense has been recorded on cats, it has not been found on dogs.
Methods In August 2019, three domestic dogs presenting pruritic dermatological lesions in the ventral area of the body
and interdigital spaces were presented at a veterinary clinic in Santarém, central Portugal. Trombiculid mites were extracted
from the skin and preserved in 70% ethanol. Specimens were prepared in slides with Hoyer’s medium and observed with
Results After morphological examination of the specimens, mites were identified as E. ibericense (Acariformes:
Conclusions Most of the trombiculids recorded in European clinical practice are generally identifed as Neotrombicula
autumnalis by default, since, in most cases, mites are not examined morphologically. This is the frst record of E. ibericense
in domestic dogs. More studies are needed to evaluate the distribution of these mites in Portugal. Veterinary clinicians must
be aware of this parasitosis, as trombiculids can cause exuberant clinical signs, but are often misdiagnosed.
