Uterus saccate, ventral, extending along median line of proglottid from near the ovarian bridge to posterior margin of first or second anterior-most row of testes (Fig. 4A).</p><p>Remarks:  Anthocephalum machadoi n. sp. is distinguishable among the 24 other species of the genus  Anthocephalum by its distinct combination of morphological features which include: 35–46 testes, 76–96 loculi, a total length of 5.8–13.6 mm, and vitelline follicles organized into two lateral bands with one dorsal and one ventral column each. In comparison with  Anthocephalum blairi Herzog &amp; Jensen, 2018,  Anthocephalum gravisi Herzog &amp; Jensen, 2018,  Anthocephalum haroldsoni Herzog &amp; Jensen, 2018, and  Anthocephalum papefayei, the new species possesses more marginal loculi (76–96 vs. 65–73, 43–52, 41–57, and 45–60; respectively). On the other hand,  Anthocephalum machadoi n. sp. posses fewer marginal loculi compared to  Anthocephalum gracile (Wedl, 1855) Ruhnke, 1994,  Anthocephalum healyae Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum lukei Ruhnke and Seaman, 2009,  Anthocephalum meadowsi Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum odonnellae Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum philruschi Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum cairae, and  Anthocephalum hobergi (Zamparo, Brooks &amp; Barriga, 1999) Marques &amp; Caira, 2016 (76–96 vs. 116–121, 150–171, 107–138, 98–134, 135–159, 200–219, 197–198, and 100; respectively).</p><p>Anthocephalum machadoi n. sp. differs from  Anthocephalum duszynskii Ruhnke, 1994 and  Anthocephalum mounseyi Herzog &amp; Jensen, 2018, in its total length (5.8–13.6 mm vs. 18–31 and 2.6–3.4 mm, respectively), and from  Anthocephalum decrisantisorum Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum jensenae Ruhnke, Caira &amp; Cox, 2015,  Anthocephalum ruhnkei Herzog &amp; Jensen, 2018, and  Anthocephalum centrurum, in number of testes (35–46 vs. 17–24, 14–20, 22–34, and 48–78, respectively). In comparison with  Anthocephalum alicae,  A. machadoi n. sp. possesses more proglottids in number (20–45 vs. 9–15, respectively).</p><p>There are only five species—  Anthocephalum currani Ruhnke &amp; Seaman, 2009,  Anthocephalum michaeli Ruhnke &amp; Seaman, 2009,  Anthocephalum jeancadenati Boudaya, Neifar &amp; Euzet, 2018,  Anthocephalum kingae (Schmidt, 1978) Ruhnke &amp; Seaman, 2009, and  Anthocephalum mattisi — that closely resembles  A. machadoi n. sp. in number of marginal loculi, number of testes, total length, and proglottid number. However, they can be distinguished based on the position and number of the vitelline follicles.  Anthocephalum machadoi n. sp. possesses vitelline follicles organized into two lateral bands with single dorsal and ventral column. In contrast,  A. michaeli,  A. jeancadenati,  A. kingae, and  A. mattisi also possess vitelline follicles in two lateral bands but with 2–3 dorsal and ventral columns. Finally  A. currani possesses vitelline follicles in two lateral bands with 3–5 dorsal and ventral columns.</p></div>	https://treatment.plazi.org/id/0399878EFF90E6691A96FC67FAC9FB18	Public Domain	No known copyright restrictions apply.

Anthocephalum miriamae n. sp. differs from  A. hobergi based on the position of the genital pore on the proglottid (32–45% vs. 66–79%). The new species also differs in the arrangement of vitelline follicles by possessing a single dorsal and a single ventral column versus the 3–5 dorsal and 3–5 ventral columns of  A. currani, 4–6 dorsal and 4–6 ventral columns of  A. lukei, and 2–3 dorsal and 2–3 ventral columns of  A. michaeli,  A. kingae, and  A. mattisi . Finally,  Anthocephalum miriamae n. sp. differs from  Anthocephalum machadoi as the former is proportionally larger, with different scolex shape (ellipsoid vs. deltoid, sensu Clopton (2004)), and associated with a distinct biogeographical region (Tropical Eastern Pacific vs. Tropical Western Atlantic), evidences that are corroborated by their phylogenetic positions based on molecular data.</p></div>	https://treatment.plazi.org/id/0399878EFF93E66C1A96FAF4FA9BFE0C	Public Domain	No known copyright restrictions apply.

Proximal surfaces of marginal loculi next to the bothridial rims covered with acicular filitriches and scolopate spinithriches (Fig. 8G, H); bothridial rims covered with acicular filitriches (Fig. 8I); distal surface of bothridium covered with capiliform filitriches (Fig. 8J).</p><p>Proglottids craspedote. Immature proglottids wider than long, becoming longer than wide with maturity, 104– 178 in number (n=9) (Fig. 3D). Mature proglottids (Fig. 7E) 1667–2230 (n=6) long by 405–577 (n=6) wide, 1–3 in number (n=9). Testes arranged in four columns from near anterior margin of proglottid to anterior margin of genital pore, and 1 row-deep in cross section (Figs. 7E, 6G). Testes 44–79 (n=5) by 31–66 (n=5) wide, 64–90 (n=4) in number. Cirrus-sac pyriform bent posteriorly, 80.5–272 (n=6) long by 76.5–161 (n=6) wide, containing coiled cirrus (Fig. 7F). Cirrus armed with spinitriches. Genital pores lateral, irregularly alternating, 29.5–38.6% (n=6) of proglottid length from posterior end (Fig. 3D, 7F). Ovary near posterior end of proglottid, H-shaped in frontal view (Figs. 3D, 7E), tetralobed in cross-section (Fig. 6H), slightly asymmetrical, 393.5–649.5 (n=6) long by 209.5–340.5 (n=6) wide; ovarian bridge near middle of ovary. Mehli’s gland posterior to ovarian bridge. Vagina thick-walled, sinuous, extending medially in proglottid from ootype to anterior margin of cirrus-sac, then laterally to open into genital atrium anterior to cirrus (Fig. 7F). Vitellarium follicular; vitelline follicles 46–74.5 (n=6) by 10.5–22.5 (n=5) wide arranged in two lateral bands, each band consisting of one dorsal and one ventral column of vitelline follicles, extending from posterior margin of the second or third anterior-most row of testes to near posterior margin of the proglottid, interrupted by genital pore both dorsally and ventrally (Figs. 7E, F). Uterus saccate, ventral, extending along median line of proglottid from near the ovarian bridge to posterior margin of first or second anterior-most row of testes (Fig. 7E).</p><p>Remarks:  Anthocephalum veronicae n. sp. is morphologically distinct from all except two species within its genus—  A. haroldsoni and  A. gravisi —by possessing uninterrupted vitelline follicles by the ovary. However, the new species is clearly different from  A. haroldsoni and  A. gravisi in total length (22.6–43.5 mm vs. 1.8–3.7 mm and 3.6–7.9 mm, respectively), by possessing a larger number of proglottids (116–180 vs. 9–16 and 17–29, respectively), a higher number of loculi (180–190 vs. 43–52 and 41–57, respectively), and more testes in number (64–90 vs. 23–38 and 25–32, respectively).</p></div>	https://treatment.plazi.org/id/0399878EFF88E6721A96FE38FDA1F848	Public Domain	No known copyright restrictions apply.

Pararhinebothroides Zamparo, Brooks, &amp; Barriga, 1999;  Alveobothrium Boudaya, Neifar &amp; Euzet, 2018 .</p><p>Worms weakly craspedote, apolytic or euapolytic. Scolex with 4 bothridia and short or absent cephalic peduncle. Bothridia stalked, with numerous marginal loculi and single apical sucker; facial loculi present or absent. Proximal surfaces of marginal loculi with acicular filitriches and with or without scolopate spinitriches, or with capilliform filitriches and narrow gladiate spinitriches; proximal non-locular surfaces of bothridia with acicular filitriches, and with or without narrow gladiate spinitriches; distal bothridial surfaces with acicular or capilliform filitriches and small gladiate spinitriches. Mature proglottids longer than wide. Testes entirely pre-ovarian, medullary; postporal field of testes lacking. Genital pores lateral, usually in posterior half of proglottid; genital atrium present. Internal seminal vesicle present or absent. Vagina sinuous, opening into genital atrium anterior to cirrus sac. Ovary posterior in position, H-shaped in frontal view, tetralobed in cross-section. Vitellaria follicular; vitelline follicles in 2 lateral bands; each band consisting of 1 or more columns of vitelline follicles, uninterrupted by ovary, or partially or completely interrupted by ovary, and interrupted or uninterrupted by genital pore. Uterus median, ventral, sacciform, extending from level of cirrus sac to stopping short of anterior limit of field of testes or to anterior margin of proglottid. Parasites of stingrays ( Myliobatiformes) and electric rays ( Torpediniformes).</p><p>Remarks: The revision of the  Anthocephalum diagnosis was necessary to accommodate the unique scolex morphology of  Anthocephalum grabatum n. comb., and  Anthocephalum zarzisense n. comb., which possess facially loculated bothridia. The incorporation of these two species raises the total number of species within the genus to 30 (Boudaya et al., 2018; Herzog and Jensen, 2018).  Alveobothrium was established by Boudaya et al. (2018) to include species morphologically akin to  Anthocephalum, but characterized by a scolex bearing staggered facial loculi arranged in multiple rows, a trait absent in  Anthocephalum sensu stricto (Ruhnke et al., 2015; Herzog and Jensen, 2018). Despite this distinguishing feature,  Alveobothrium shares all other morphological characteristics with  Anthocephalum, leading the authors to recognize  Alveobothrium on the basis of its unique scolex morphology alone.</p><p>Phylogenetic analyses have previously supported the inclusion of tapeworms with varying scolex morphologies within a single genus of chondrichthyan parasites (e.g., Reyda et al., 2016; Trevisan et al., 2017; Caira et al., 2020). For example,  Anindobothrium lisae Marques, Brooks &amp; Lasso, 2001, a parasite of freshwater stingrays, lacks facial loculi and longitudinal septa, which contrast with marine species of the same genus that exhibit these features. Despite these differences,  Anindobothrium lisae shares key morphological traits with other members of the genus and is confirmed by molecular evidence to belong to  Anindobothrium (Trevisan et al., 2017) . Additionally, in a recent redefinition of  Scyphophyllidium Woodland, 1927 ( Phyllobothriidea), Caira et al. (2020) examined six genera with similar proglottid anatomy and unique ultrastructural characteristics but divergent bothridial morphologies, such as the presence or absence of apical suckers and loculi. They concluded that bothridial morphology represented intra-genus diversity and proposed synonymizing the six genera under  Scyphophyllidium, organizing the species into eight groups based on bothridial morphology. Similarly, despite differences in bothridial morphology, species of  Anthocephalum and  Alveobothrium display comparable proglottid anatomies. In our phylogenetic analysis, the positioning of  Alveobothrium grabatum alongside other  Anthocephalum species is strongly supported. This result, when considered in conjunction with the aforementioned evidence, substantiates the proposed taxonomic synonymy.</p></div>	https://treatment.plazi.org/id/0399878EFF89E6701A96F9DBFECEFBA0	Public Domain	No known copyright restrictions apply.
