“…Neoechinorhynchus veropesoi n. sp. differs from N. pimelodi , which was reported by Brasil-Sato & Pavanelli (1998), in the São Francisco River basin, Três Marias, Minas Gerais, Brazil, because the latter species has a smaller size, with a total length of 1.15–1.67 (1.45) mm in males and 1.18–3.97 (2.44) mm in females; a LWR of 2:1 for both sexes; and anterior, middle and posterior proboscis hooks measuring 100–112 (105), 32–40 (36) and 20–27 (23) in males and 102–142 (129), 34–55 (47) and 27–35 (29) in females, respectively.…”

“…belongs to the group that presents proboscis hooks in the anterior circle that are equal, lemnisci equal or subequal, with small worms, anterior proboscis hooks at least three times as long as the middle hooks, and middle and posterior proboscis hooks unequal, which gradually or abruptly decrease in length. This group includes the species N. paraguayensis Machado-Filho, 1959, N. pteridoridis Thatcher, 1981 and N. pimelodi Brasil-Sato & Pavanelli, 1998.…”

“…In Brazil, six species are known, including N. macronucleatus Machado-Filho, 1954; N. buttnerae Golvan, 1956; N. paraguayensis Machado Filho, 1959; N. curemai Noronha, 1973; N. pterodoridis Thatcher, 1981; and N. pimelodi Brasil-Sato & Pavanelli, 1998; which are all parasites of freshwater and marine fish (Amin, 2002; Santos et al , 2008). Thus far, only Rhadinorhynchus plagioscioni Thatcher, 1980, a parasite of P. squamosissimus , has been reported.…”

Plagioscion squamosissimus (Heckel, 1840) (Osteichthyes: Sciaenidae) is considered piscivorous and is a generalist species endemic to the Amazon region. This fish is an important part of the natural ecosystems in which it occurs and provides basic functional components in the food web. The genus Neoechinorhynchus Stiles & Hassall, 1905 is distributed worldwide and parasitizes fish and turtles, but there are few reports of parasites of this genus in South America, due to the high diversity of fish that can be found in this region. A new species of thorny-headed worm (Acanthocephala: Neoechinorhynchidae) is described from P. squamosissimus from Guajará Bay, Belém, Pará, Brazil. In general, the unique characteristics of the hooks on the anterior end of the proboscis and the length-to-width ratio relationship separate this new species from other described species in the genus Neoechinorhynchus. Although the species in this genus are mostly found in North America, the dearth of species known from the neotropics may be due to the lack of studies in this region.

Recent Studies on Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae), in Prochilodus lineatus Valenciennes, 1836, from Volta Grande Reservoir, MG, Brazil

The present work described helminth parasites of curimbatá, Prochilodus lineatus Valenciennes, 1836 from Volta Grande Reservoir, MG, Brazil. Eighteen fishes with average 46.7 ± 1.1 cm length and 1,674.8 ± 75.6 g weight were collected. Of the analysed fishes, 15 were parasitized with acanthocephalans in the intestine, showing a prevalence of 83.3%. The helminth was identified as Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae). It differs from other species in dimension of characters and morphology. From the original description of N. curemai, it differs from the biggest dimension of testis, elongated cement gland, nucleated lemnisci, eggs size, larger proboscis hooks length in the middle and in the third circle in males and larger hooks in the anterior circle in females. A smaller percentage occupied by the reproductive system in female trunk was reported. The observation of paratypes of N. curemai of Noronha (1973) showed a great similarity with those of the present work. This fact complements the helminth description from elsewhere.

A redescription of Neoechinorhynchus (Neoechinorhynchus) golvani Salgado-Maldonado (An Inst Biol Univ Nal Autón Méx, Ser Zool 49:35-47, 1978) is presented, based on adult specimens collected from the type host Paraneetroplus fenestratus from the type location, the Lago de Catemaco lake, Veracruz state, Mexico, and its presence is recorded in other cichlids. Detailed studies of N. (N.) golvani using light microscopy revealed some taxonomically important, previously unreported features, such as the size and shape of fully developed adult males and females, and the structure of the eggs. Morphological variability in N. (N.) golvani is described. Based on these data, the geographic distribution of this species is documented. Neoechinorhynchus (Neoechinorhynchus) panucensis n. sp. is described from Herichthys labridens (Pellegrin), Amatitlania nigrofasciata (Günther), and Herichthys cyanoguttatus Baird and Girard (all of them Cichlidae), collected in the Río Atlapexco, a tributary to the upper Río Panuco basin, Hidalgo State, Mexico. This new species stand up alone because of its minute proboscis (♂ 50 × 60, ♀ 42-55 (48.5) × 48-63 (57.7)) and anterior hooks (♂ 27-30 (28.8) × 3-5 (4), ♀ 28-32 (30) × 5 (5)). A key to the species of Neoechinorhynchus recorded from freshwater fishes in Central and South America is included.
