Tegument smooth. Cephalic region broad; cephalic lobes inconspicuous; three bilateral pairs of head organs with rod-shaped secretion; cephalic glands not observed. Two pairs of eyespots; anterior eyes slightly farther apart than posterior pair; accessory chromatic granules absent. Mouth subterminal, midventral; pharynx muscular, ovate to subspherical, 31 (27–28; n= 6) long, 28 (24–32; n=6) wide; esophagus short. Two intestinal ceca, confluent posteriorly to gonads, lacking diverticula. Common genital pore opening midventral near level of cecal bifurcation; genital atrium muscular. Intercecal gonads, overlapping. Testis dorsal to germarium, fusiform, 37 (25–50; n=2) long, 28 (15–42; n=2) wide (observed only in paratypes). Vas deferens apparently looping left intestinal cecum; seminal vesicle sigmoid, representing a dilation in the vas deferens, with distal portion looping posteriorly before entering MCO base. Single prostatic reservoir, bifurcated, posterior to copulatory complex. Copulatory complex comprising MCO, accessory piece (Fig. 2). MCO sclerotized, tubular, spiral, counterclockwise, with two coils, 139 (100–157; n=4) long, base with sclerotized cap, distal aperture acute; circular sclerotized tandem brim associated with MCO base. Accessory piece, articulated with MCO, comprising complex sheath with distal portion expanded, bifid. Germarium fusiform, 52 (40–80; n=4) long, 23 (22–25; n=4) wide. Eggs, Mehlis’ glands, ootype not observed. Vagina single, sclerotized, opening ventrally at the left body margin, at level of vitelline commissure; vaginal vestibule heavily sclerotized at distal portion; vaginal canal sclerotized, sigmoid. Seminal receptacle broad, anterior to germarium. Vitellaria well developed, coextensive with intestinal ceca. Haptor subtrapezoidal, 150 (125–175; n=4) long, 117 (100–137; n=4) wide. Anchors dissimilar. Ventral anchor 111 (107–115; n=5) long, with inconspicuous roots; base 36 (32–38; n=5) width, with sclerotized cap; shaft recurved near mid-length, point with fish-hook-like termination (Fig. 8). Dorsal anchor 120 (114–130; n=4), with blunt proximal end covered by subtle sclerotized cap, straight shaft, tapered distal end (Fig. 9). Ventral bar with ends ventrally bent toward to its posterior portion (Figs 6–7). Dorsal bar absent. Hooks dissimilar in shape, comprising shank of two subunits; filamentous hook loop extended near to beginning of shank dilation; hook pair 2, 28 (25–32; n=10) long, with erect thumb, curved shaft, short point, proximal ½ of shank inflated (Fig. 3); hook pairs 1, 3–7, 32 (30–35; n=7) long, with slightly depressed to straight thumb, slightly curved shaft, short point, proximal ¾ of shank inflated (Figs. 4–5).</p><p>Remarks: Rhinoxenus cachorra n. sp. is similar to Rhinoxenus euryxenus Domingues &amp; Boeger, 2005 mainly due to the morphology of the haptoral structures. Both species have a ventral anchor with inconspicuous roots and a sclerotized cap on the base of the anchor with projection for articulation to ventral bar; shaft recurved near the mid-length, point with fish-hook-like termination; a ventral bar with ends ventrally bent toward to its posterior portion. The new species differs from R. euryxenus by the presence of a spiraled MCO with two counterclockwise coils (from one and a half to two coils in R. euryxenus), and an accessory piece with an expanded, bifurcated distal portion (cone-like in R. euryxenus). Finally, these species differ on the morphology of the point of the ventral anchor and hook pair 2; R. euryxenus has the point of ventral anchor with saucer-like termination, and the hook pair 2 is robust, with an erect and robust thumb, whereas Rhinoxenus cachorra n. sp. has the point with hook-like termination, the hook pair 2 is not robust and its thumb, although erect, is also not robust.</p></div>	https://treatment.plazi.org/id/03F98793FFDEFFDEE3DAFAD06C25FAE9	Public Domain	No known copyright restrictions apply.

Ventral bar with anteromedial projection. Parasites of gills of characiform fishes.</p><p>Remarks: Mymarothecioides n. gen. resembles Mymarothecium Kritsky, Boeger &amp; Jegú 1996, mainly by including species with broad arcuate MCO, articulated with the accessory piece; the accessory piece with a subterminal hooked process; an anteromedial process on the ventral bar. The genera are distinguished by Mymarothecioides n. gen. having a dextro, midventral vaginal opening (middorsal or dextro-dorsal in Mymarothecium) and by lacking eyespots (four eyespots in Mymarothecium). These combined characters support the transfer of Mymarothecium whittingtoni Kritsky, Boeger &amp; Jégu, 1996 to Mymarothecioides n. gen. as Mymarothecioides whittingtoni (Kritsky, Boeger &amp; Jégu, 1996) n. comb.</p></div>	https://treatment.plazi.org/id/03F98793FFD8FFDFE3DAFA4769F2FD15	Public Domain	No known copyright restrictions apply.

Cephalic margin tapered; moderately developed terminal lobes; four to five bilateral pairs of head organs with rod-shaped secretion; cephalic glands unicellular, posterolateral to pharynx (observed only in paratypes). Accessory chromatic granules present in the cephalic area. Pharynx subspherical, 26 (24–32; n= 3) long, 19 (14–24; n=3) wide. Testis fusiform, 63 (47–79; n=3) long, 28 (25–32; n=2) wide (observed only in paratypes); prostatic reservoir saculiform, separated into two zones. MCO, 50 (50–51; n=3) long, with distal portion expanded, bent; base of MCO with broad sclerotized margin (Fig. 35; 45). Accessory piece comprising straight rod, distal portion with subterminal flap with hook, thumb. Germarium fusiform, 73 (51–95; n=2) long, 17 (16–19; n=2) wide. Eggs, seminal receptacle, Mehlis’ glands, ootype not observed. Vaginal aperture midventral, opening at level of vitelline commissure; vaginal vestibule heavily muscular; vaginal canal sigmoid. Uterus delicate; seminal receptacle elongated, with dense musculature. Vitelline follicles dense. Peduncle broad; haptor subhexagonal, 74 (67–80; n=3) long, 98 (82–112; n=3) wide. Anchors similar. Ventral anchor, outer 36 (n=2) long, inner 40 (39–41; n= 2) long, base 16 (n=2); superficial root triangular; deep root poorly developed, rounded; evenly curved shaft and point; point extending just past level of tip of superficial root (Fig. 40). Dorsal anchor, outer 34 (33–35; n=2) long, inner 32 (n= 2) long, base 12 (n=2); superficial root triangular with slightly depressed tip; deep root elongated; slightly curved shaft and point; point extending to level of tip of superficial root (Fig. 41). Ventral bar, 54 (49–62; n=3) long, 9 (6–11; n=3) wide, slightly curved to broadly inverted V-shaped rod with anteromedial projection, rounded ends (Fig. 38). Dorsal bar, 55 (54–57; n=3) long, 5 (5–4; n=3) wide, slightly curved rod with anteromedial projection, rounded ends (Fig. 39). Hooks similar in shape, with upright thumb, rounded, slightly curved shaft; short point; shank divided into two units, proximal unit compressed, distal unit inflated; filamentous hook loop not observed; hook pairs 1–4, 6–7, 23 (22– 26; n=7) long (Fig. 36); hook pair 5, 20 (15–16; n=6) long (Fig. 37).</p><p>Remarks: Mymarothecioides germanoi n. sp. is similar to M. xinguensis n. sp. based on the morphology of anchor/bar complexes. However, the new species is easily distinguished from M. xinguensis and other congeneric species by possessing a midventral vaginal pore.</p></div>	https://treatment.plazi.org/id/03F98793FFD7FFD4E3DAFE576ABEFF21	Public Domain	No known copyright restrictions apply.
