Diagnosis. Large euryteles with shaft:capsule proportion 3.0– 3.6; in pads on hydranth body, spadix of female gonophores, and in a whorl of 16–25 around hypostome. Female blastostyles with reduced hypostome and tentacles. Etymology. From the Tupi native language “ cáraiurú ” (= powerful mouth), in reference to the presence of large euryteles on the hypostome. Description. Colonies dioecious, arborescent, up to 54 mm in height, main stems unfascicled. Hydrocauli arising from creeping hydrorhiza; branches many, more or less alternate, occurring over entire hydrocaulus, branches up to third order, in radiate planes or rarely more or less planar; pedicels arising from main stem or branches of first, second or third order. Perisarc of main stem strongly developed, dark brown, single tubes 0.40 mm in diameter, with scarce annulations, in sets of 3–8 rings. Branches with 3–7 rings at origin, 0.20–0.25 mm in diameter. Pedicels sometimes completely annulated, yellowish, ca. 0.10 mm in diameter. Hydranths 0.18–0.75 mm in height, 0.18–0.57 mm in diameter (measured in the body region just below the tentacles), orange in color, with a distinct groove in the aboral region; tentacles 23–34 in number, occurring in a whorl below hypostome. Some hydranths with reduced tentacles juxtaposed in two close whorls. Gonophores styloids, arising from body of hydranth. Immature styloids placed in a circle around body of hydranth. Male blastostyle orange, with 10–29 sporosacs, each sporosac 1–2 chambered, linked to blastostyle body by a stalk, with a very distinct spadix over its longitudinal axis, and a terminal tubercle on its apex; distal chamber 0.12–0.18 mm in diameter. Male blastostyles completely reduced over earlier stages of their development with pedicels corrugated throughout. Female gonophores orange, arising on partially reduced blastostyles with highly atrophied hypostome and degenerated tentacles. Immature eggs having a simple and curved spadix over a single egg. Blastostyle reducing completely during development or at maximum with 1–5 stumps (tentacles), and spadices shed. Mature oval eggs thickened by perisarc and linked directly to the wrinkled pedicel by short and shallow concave peduncles. Eggs 4–7 in number, 0.24–0.39 mm in diameter. Nematocysts of two categories, heterotrichous microbasic euryteles and heterotrichous macrobasic (or mesobasic) euryteles. Small microbasic euryteles (seen discharged), 6.1 –8.0 X 2.9–3.9 m, L / W = 1: 2.05– 2.1, oval, abundant; distributed over hydranth body, hypostome, coenosarc, and tentacles. Large macrobasic euryteles (seen discharged), 18.7–22.7 X 7.1–9.3 m, L / W 1: 2.4– 2.6, bean shaped, common. Discharged shaft up to 60 m in length, 3. 0–3.6 times length of capsule; undischarged shaft in 1.5 coils inside capsule; distributed on hydranth body sometimes forming pads to a continuous ring, up to 25 capsules on hypostome, coenosarc, terminal tubercle, and immature female spadix sometimes forming pads.

Ahamulina Marques, Jensen & Caira, 2012, n. gen.
Ahamulina n. gen. Type species: Ahamulina catarina n. sp. Etymology: Ahamulina (hamulus, L., diminutive, hooks) refers to the absence of lateral hooklets in members of this genus. Diagnosis: Scolex with 1 dorsal and 1 ventral bothrium, armed apical organ, and cephalic peduncle. Bothria free posteriorly for much of their length, with trifurcate spinitriches on proximal and distal surfaces. Apical organ bearing 1 dorsal and 1 ventral group of hooks; hooks in each group solid, arranged in single, irregular row; adjacent hooks not articulating with one another; lateral hooklets absent. Cephalic peduncle short, unarmed, craspedote. Worms apolytic. Common genital pore mid-ventral. Cirrus sac bipartite, consisting of spherical proximal portion and tubular distal portion, containing coiled cirrus; cirrus with spinitriches. Vagina opening posterior to cirrus sac at common genital pore. Ovary inverted-A shaped in frontal view, bilobed in cross-section. Vitellarium follicular; vitelline follicles circumcortical, anterior to ovary. Uterus saccate, ventral; uterine duct extensive, sinuous, entering in posterior third of uterus. Eggs in gravid proglottids unembryonated. Parasites of Scyliorhinidae III sensu Naylor et al. (2012). Remarks: Ahamulina n. gen. differs from Ditrachybothridium in its possession, rather than lack, of apical organ hooks. Furthermore, the apical organ of this new genus is prominent, rather than feebly developed. The apical hooks of Ahamulina n. gen. are unlike those of Echinobothrium species in that they are solid, rather than hollow, do not articulate with one another, and the dorsal and ventral groups of hooks are each arranged in a single, rather than a double, row and thus, the distinction between type A and B hooks seen in species of Echinobothrium is not seen in Ahamulina n. gen. Furthermore, lateral hooklets flanking the dorsal and ventral groups of hooks in most of Echinobothrium species are lacking entirely. The absence of cephalic peduncle spines, while unusual, is not unique, given that these spines are also lacking in several species of Echinobothrium (e.g., E. benedeni Ruszkowski, 1927, E. euterpes [Neifar, Tyler & Euzet, 2001] Tyler, 2006; E. reesae Ramadevi, 1969; E. rhynchobati [Khalil & Abdul-Salam, 1989] Tyler, 2006; E. sinense [Li & Wang, 2007] Kuchta & Caira, 2010; E. syrtense [Neifar, Tyler & Euzet, 2001] Tyler, 2006) and also in both species of Ditrachybothridium. The bipartite nature of the cirrus sac seen in this new genus is also unique among diphyllideans. Ahamulina n. gen. differs further from all of the diphyllideans that have been examined with scanning electron microscopy in that all surfaces of the scolex lack palmate and/or pectinate spinitriches or spines; instead trifurcate spinitriches are present on both the proximal and distal bothrial surfaces. It should be noted that, although Tyler (2006) referred to the spinitriches seen in D. macrocephalum as pectinate, based on the formalized new microthrix terminology proposed by Chervy (2009), the form he illustrated (fig. 21 D) would more appropriately be considered to be trifurcate.Published as part of Marques, Fernando P.

Rhinebothrium reydai Trevisan & Marques 2017, n. sp.
Rhinebothrium reydai n. sp., Family Rhinebothriidae, order Rhinebothriidea (Figs. 5–8) Type host: Styracura schmardae (Werner) de Carvalho, Loboda & da Silva (Myliobatiformes: Potamotrygonidae). Type locality: Caribbean Sea off Almirante, Bocas Del Toro Province, Panama (09°17'N, 82°20'W and 09°17'N, 82°21'W). Site of infection: Spiral intestine. Type specimens: MIUP CR1 (Holotype) and CRP1–CRP9 (Paratypes: 9 complete worms); MZUSP 7931a– 7931p (Paratypes: 16 complete worms), 7932 (1 SEM vouchers), and 7933a–7933d (voucher and histological sections); HWML 110076–110082 (Paratypes: 7 complete worms); LRP 9270–9276 (Paratypes: 7 complete worms). Prevalence of infection and distribution: 45,5% (five of 11 spiral intestines), seeming to be restricted to the Caribbean coast of Panama. Etymology: The species is named in honor of Dr. Florian B. Reyda, who took part in the sampling trip to Panama and who has contributed to the knowledge of this group of cestodes for many years. Description. [Based on 50 mature specimens: 47 whole mounts, one worm observed with SEM, and two prepared as cross-sections]. Worms acraspedote (Fig. 5), euapolytic, 2.2–7.4 mm (n = 47) long, composed of 26–68 (n = 47) proglottids. Scolex 237–376 (n = 8) in maximum width composed of four stalked and billobed bothridia constricted at center, with muscular rims (Fig. 6 A, 7A). Bothridia 280–461 (n = 9) long by 111–202 (n = 9) wide, divided by 17–22 (n = 15) transverse septa and one medial longitudinal septum into 34–44 (n = 15) loculi; anteriormost and posterior-most loculus single. Anterior-most loculus 18–26 (n = 10) long by 29–41 (n = 10) wide. Cephalic peduncle absent. Proximal and distal surface of bothridia covered with acicular filitriches and gladiate spinitriches (Fig. 7 C–G), except for anterior loculus with acicular filitriches only (Fig. 7 B). Anterior portion of strobila covered with capilliform filitriches (Fig. 7 H). Immature proglottids wider than long, becoming as long as wide within the anterior third of the strobila (13– 30%, n = 39) thereafter, longer than wide with maturity, 19–56 (n = 47) in number (Fig. 5). Terminal mature proglottids (Fig. 6 B, D) 218–554 (n = 42) long by 67–146 (n = 43) wide, 4–14 (n = 47) in number. Some terminal proglottids with sperm-filled vas deferens and atrophied testes (Fig. 6 B). Testes in two irregular columns, in anterior ¾ of proglottid, oval, 20–43 (n = 27) long by 17–34 (n = 27) wide, 4 (n = 47) in number (Fig. 6 D, 8A). Cirrus sac in anterior ½ of proglottid, spherical to pyriform in shape, 33–59 (n = 39) long by 37–83 (n = 39) wide, containing coiled cirrus; cirrus armed with spinitriches (Fig. 6 C). Genital atrium prominent. Genital pores 31–49% (n = 42) of proglottid length from anterior end, irregularly alternating. Vagina opening into genital atrium anterior to cirrus sac, thick-walled, weakly sinuous, somewhat enlarged in proximal part, with antero-medial portion adjacent to cirrus sac, both directed laterally to common genital atrium. Vaginal sphincter absent. Ovary near posterior end of proglottid, inverted A-shaped in frontal view and tetra-lobed in cross-section (Fig. 8 B), symmetrical, 89–316 (n = 40) long by 39–79 (n = 40) wide at isthmus (Fig. 6 B). Vitelline follicles extending length of proglottid, longer 5–15 (n = 14) than wide 4–12 (n = 14). Detached gravid proglottids and eggs not observed. Remarks. This new taxon is unique among species of Rhinebothrium due to a combination of morphological characters, including the presence of only four testes and a single posterior-most bothridial loculus. Compared to other 11 species that share the presence of four testes, only R. chollaensis Friggens & Duszynski, 2005 possesses a single posterior-most bothridial loculus. Rhinebothrium reydai n. sp. further resembles R. chollaensis in total length (2.2–8.4 vs. 1.3–5.1, respectively), number of proglottids (26–68 vs. 32–84, respectively), and number of bothridial loculi (34–44 vs. 40–49, respectively). Both species also have similar bothridial morphology. Friggens & Duszynskii (2005) described R. chollaensis as having leaf-like bothridia with a slight constriction at the level of the stalk, which is similar to what we observed in R. reydai n. sp.. However, after examining images from the type series of R. chollaensis (Holotype [USNM 92213] and five paratypes [USNM 92213a–92214d]), we think that the constriction is more pronounced in the former, hence described as bilobed. Despite a similar morphology, R. chollaensis is apolytic whereas R. reydai n. sp. is euapolytic. Based on the type series, both species differ on the morphology of the aporal lobe of the ovary, which reaches the mid-lateral margin of the cirrus sac in R. chollaensis, whereas in R. reydai n. sp. the aporal lobe only reaches the posterior margin, since the cirrus sac takes approximately ¾ of the proglottid in width. Also, in R. reydai n. sp. the first square proglottid occurs within the anterior third of the strobila (13–30%, n = 39), whereas in the type series of R. chollaensis it occurs near the middle of the strobila (42–62%, n = 6). The morphological resemblance between these two species and their biogeographical distributions (i.e., R. chollaensis from the eastern Pacific Ocean vs. R. reydai n. sp. from the western Atlantic Ocean), might also suggest a close phylogenetic association, which has yet to be tested within the context of a phylogenetic study.Published as part of Trevisan, Bruna & Marques, Fernando P.
