“…Among the extant orders of tapeworms, assuming that Proteocephalidea is not included in the Onchoproteocephalidea (Arredondo et al ., 2014), 13 have been recorded in fish from South America, making the Proteocephalidea the most representative group so far, with over 100 species within 37 genera, primarily infecting freshwater siluriforms (81% of HPAs) in the Amazon and Paraná River basins. For instance, the second-richest order, Onchoproteocephalidea ( pro parte ), has only about 44 described/reported species, parasitizing marine and freshwater elasmobranchs (only Acanthobothrium chilensis Rego, Vicente & Herrera, 1968 is known from a teleost fish).…”

The South American subcontinent supports one of the world's most diverse and commercially very important ichthyofauna. In this context, the study of South American fish parasites is of increased relevance in understanding their key roles in ecosystems, regulating the abundance or density of host populations, stabilizing food webs and structuring host communities. It is hard to estimate the number of fish parasites in South America. The number of fish species studied for parasites is still low (less than 10%), although the total number of host-parasite associations (HPAs) found in the present study was 3971. Monogeneans, with 835 species (1123 HPAs, 28.5%), and trematodes, with 662 species (1127 HPAs, 30.9%), are the more diverse groups. Data gathered from the literature are useful to roughly estimate species richness of helminths from South American fish, even though there are some associated problems: the reliability of information depends on accurate species identification; the lack of knowledge about life cycles; the increasing number of discoveries of cryptic species and the geographically biased number of studies. Therefore, the closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data. Research on biodiversity of fish parasites in South America is influenced by problems such as funding, taxonomic impediments and dispersion of research groups. Increasing collaboration, interchange and research networks in the context of globalization will enable a promising future for fish parasitology in South America.

“…A putative synapomorphy, i.e. the presence of simple gladiate microtriches, is also questionable and has to be verified because detailed data on surface ultrastructure are available for only about 30 species of proteocephalideans (out of more than 300 nominal species - Arredondo et al 2014).…”

“…However, Caira et al (2014) also specified that the homology between the cephalic peduncle and the proliferation zone or neck had yet to be proven. This was also discussed by Arredondo et al (2014) who evaluated the presence of gladiate spinitriches in proteocephalideans and showed that this type of microtriches are not always found in such region. The study of the ultrastructure of microtriches could help to determine similarities between the members of the order Onchoproteocephalidea.…”

The internal ultrastructure of the scolex and the histochemical composition of the apical glands of two South American proteocephalideans cestodes, Monticellia magna and Proteocephalus pimelodi, were described for the first time. The study included the use of scanning and transmission electron microscopy to observe the tegumental ultrastructure, and histochemical techniques to detect types of gland secretion. Two types of glands were found in the scolex of M. magna and P. pimelodi. The pattern of microtriches described for M. magna was confirmed and that of P. pimelodi was described for the first time. Also, the internal ultrastructure of the microtriches in both species was described. Indications of the presence of sensory receptors were also found in M. magna. Finally, the systematic value of the characters studied is discussed, such as the internal structure of the gladiate spinitriches and the apocrine gland of M. magna.
