“…While EDX spectra and weight-percentages are both regarded as highly qualitative, EDX analysis appears to be indicative of specific species. For example, sodium, a rarely prominent element, is evident in EDX spectra of whole hooks of Microsentis wardae (Martin and Multani, 1966) and of Pallisentis nandai Sarkar, 1953 [ 10 ], as well as in egg shells of Neoechinorhynchus qatarensis Amin, Saoud, Alkuwari, 2002 [ 28 ]. Similarly, Moniliformis cryptosaudi from Iraq is morphologically identical to Moniliformis saudi Amin, Heckmann, Mohammed, Evans, 2016 from Saudi Arabia, and it was erected based primarily on its distinctly different EDXA [ 7 ], as a cryptic species.…”

“…This pattern is nearly opposite to that of P. rancoensis cystacanths and emphasizes the characteristic EDXA diagnosis for each species. Anterior and middle hooks of cystacanths of Sphaerirostris picae (Rudolphi, 1819) Golvan, 1956 from lizards and hedgehogs in Ukraine had moderate levels of phosphorus and sulfur (4.41–6.03%) and slightly higher levels of calcium (9.61–10.83%); again, showing variation in EDXA that is species specific [ 10 ]. Cystacanths of Moniliformis kalahariensis [Meyer, 1931], from Blatella germanica Linn.…”

“…Cystacanths of Moniliformis kalahariensis [Meyer, 1931], from Blatella germanica Linn. in India, had characteristically very low levels of phosphorus, sulfur, and calcium in anterior, middle, and posterior hooks alike [ 10 ]. A detailed discussion of the biological significance of EDXA as a diagnostic tool is exemplified by the observation that populations of an acanthocephalan species will consistently have similar EDX analysis irrespective of host species or geography, even though comparative morphometrics of different populations of the same species usually vary with host species and geography, as presented in Amin et al [ 9 , 10 ].…”

Profilicollis rancoensis n. sp. is the tenth species of Profilicollis Meyer, 1931 which includes 9 other species mostly known from marine decapod crabs and shore birds. Cystacanths of P. rancoensis are described from the dominant freshwater crab Aegla abtao in Ranco Lake, Chile and are morphologically distinguished from cystacanths of the 9 other species based on a combination of 4 characters. These are body size, number of proboscis hook rows, number of hooks per row, and length of the largest anterior 2–4 hooks. Male and female cystacanths of P. rancoensis are 2.10–3.33 mm long having an ovoid proboscis with 14 rows of 6–7 hooks per row, with the largest anterior 2–4 hooks being 105–110 micrometers long; the anterior trunk has many small spines in 70–80 concentric rings, each with 50–60 spines around them; hook roots are simple, directed posteriorly, about as long as the blades anteriorly with unremarkable anterior manubria; the cephalic ganglion are in mid-receptacle just anterior to the level of the anterior trunk; the lemnisci are long and slender; the testes are in the anterior trunk, posterior trunk, or one in each; the primordia of 2 tubular cement glands are evident; strong bundles of fibers link the anterior and posterior trunk; and the posterior trunk has a corrugated surface cuticula. Molecular analysis (COI and 18S) sequences coincided with the morphology and support its taxonomy. The phylogenetic profile revealed that P. rancoensis n. sp. fell into the Profilicollis clade. Both sequences showed low genetic variation, and three different haplotypes were found. The new species was more closely related to P. botulus (Van Cleave, 1916) Witenberg, 1932 than to other Profilicollis species.

“…Another tool, complementary to the description of proboscis ultrastructure by SEM and Transmission Electron Microscopy (TEM), is energy dispersive X-ray analysis (EDXA). EDXA provides information on part of the macroelemental composition of hooks (e.g., calcium, sulfur, and phosphorus), functionally related to hook hardness vs. flexibility (see [8,10]). These tools could inform on structural-functional relationships of unique features of acanthocephalans, mainly anchoring structures involved in attachment and micropores for nutrient uptake in the intestinal wall of their definitive hosts [10,13].…”

Although interest in Acanthocephala seems to have reached only a small community of researchers worldwide, we show in this opinion article that this group of parasites is composed of excellent model organisms for studying key questions in parasite molecular biology and cytogenetics, evolutionary ecology, and ecotoxicology. Their shared ancestry with free-living rotifers makes them an ideal group to explore the origins of the parasitic lifestyle and evolutionary drivers of host shifts and environmental transitions. They also provide useful features in the quest to decipher the proximate mechanisms of parasite-induced phenotypic alterations and better understand the evolution of behavioral manipulation. From an applied perspective, acanthocephalans’ ability to accumulate contaminants offers useful opportunities to monitor the impacts – and evaluate the possible mitigation – of anthropogenic pollutants on aquatic fauna and develop the environmental parasitology framework. However, exploring these exciting research avenues will require connecting fragmentary knowledge by enlarging the taxonomic coverage of molecular and phenotypic data. In this opinion paper, we highlight the needs and opportunities of research on Acanthocephala in three main directions: (i) integrative taxonomy (including non-molecular tools) and phylogeny-based comparative analysis; (ii) ecology and evolution of life cycles, transmission strategies and host ranges; and (iii) environmental issues related to global changes, including ecotoxicology. In each section, the most promising ideas and developments are presented based on selected case studies, with the goal that the present and future generations of parasitologists further explore and increase knowledge of Acanthocephala.

In this study, 45 individuals (18 female, 20 male, and 7 juvenile) of the Yellow-bellied Toad, Bombina variegata were collected from Karacahasan Mountain region (located in the Enez district of Edirne province in northwestern Türkiye) in 2015–2016 and examined for helminths. Two species of Digenea (Gorgodera cygnoides and Pleurogenoides medians) and one species of Acanthocephala (Acanthocephalus ranae) were found. This study is the first helminth study and only helminth study conducted on B. variegata from Türkiye.
