| Abstract | Capillariidae is a group of nematode parasites of vertebrates with a complex taxonomy. The structure of the eggshell, which was
indicated as the most important characteristic for identification of genus or species through eggs, is very diverse among genera.
The visualization and characterization of eggshell by light microscopy (LM) are a challenging task since different planes of the
egg surface are needed. Nevertheless, categories of eggshell ornamentation were proposed by LM: smooth, punctuated, reticulated
type I, and reticulated type II. The present study aimed to characterize the eggshell structure of Capillariidae species,
parasites of mammals and avians, deposited in a helminthological collection using scanning electron microscopy (SEM).
Institutional Biological Collections are taxonomic repositories of specimens described and strictly identified at the species level
by systematics specialists. SEM eggshell images were obtained from 12 species belonging to 5 genera (Aonchotheca,
Baruscapillaria, Capillaria, Echinocoleus, Eucoleus) and compared to their respective LM images. Eggshell patterns observed
using SEMwere associated categories of eggshell ornamentation previously proposed byLMimages. The SEMdata indicate that
eggshell categories are not in agreement with capillariid genera or sites of infection. However, the study provides previously
unknown SEM eggshell information from curated species, which contributes with a specific and supplementary taxonomic
feature at the species level of Capillariidae. | pt_BR |
