(Based on 27 specimens mounted in Hoyer’s medium): Body elongated, fusiform, 363 (256 – 470, n = 27) long, including haptor, by 138 (108 – 195, n = 27) wide at level of ovary; tegument smooth; three developed cephalic lobes, two lateral and one terminal; four pairs of head organs; cephalic glands indistinct; accessory granules sparse in cephalic area; four equidistant eyespots, eye granules elongate ovate. Pharynx 32 (28 – 38, n = 5) in diameter; esophagus short; caeca confluent posterior to testis, without diverticula (Fig. 2 A). Copulatory complex comprises male copulatory organ (MCO) and accessory piece. MCO 111 (92 – 123, n = 16) long and 18 (15 – 22, n = 15) wide, composed of 2 clockwise rings; accessory piece 40 (27 – 50, n = 22) long, 12 (10 – 14, n = 19) wide, non-articulated to MCO base, bifurcated, with unequal branches at distal portion, the longest widens to distal region, with a subterminal thin projection and terminal end hook-shaped (Fig. 2 B). Gonads slightly overlapping. Testis dorsal to germarium; vas deferens looping left intestinal cecum; seminal vesicle elongated and single rounded prostatic reservoir. Germarium pretesticular; seminal receptacle, Mehlis’ glands, ootype, eggs, and uterus not observed (Fig. 2 A). Vagina weakly sclerotized, opening ventrally, forming a bulb near the aperture, vaginal canal long, thin (Fig. 2 C). Vitellaria distributed throughout the trunk (Fig. 2 A). Peduncle broad; haptor subhexagonal 97 (75 – 133, n = 25) wide. Ventral anchor 17 (13 – 20, n = 26) long, straight, with short deep root, superficial root developed presenting a little hump between the superficial and deep roots, base 14 (11 – 16, n = 26) wide (Fig. 2 D); dorsal anchor 31 (23 – 37, n = 27), long, with differentiated roots, well-developed superficial root, and short and developed deep root, base 19 (14 – 22, n = 24) (Fig. 2 E). Ventral bar 27 (22 – 35, n = 26) long, yoke-shaped, with enlarged extremities and delicate postero-medial umbiliform membrane (Fig. 2 F, G); dorsal bar 19 (15 – 22, n = 25) long, straight, with extremities directed posteriorly (Fig. 2 H). Hook pairs similar in shape and dissimilar in size, pairs 1 and 5 slightly smaller: Pair 1, 11 (11 – 12, n = 10); pair 2, 12 (12 – 13, n = 10); pair 3, 13 (12 – 13, n = 10); pair 4, 13 (13, n = 10); pair 5, 11 (10 – 12, n = 9); pair 6, 13 (12 – 13, n = 9); pair 7, 12 (12 – 13, n = 9) with Ancyrocephalinae distribution, straight shank with protuberant thumb, recurved shaft, point; FH loop about ¾ shaft length.	en	Silva, Marciara L., Ottoni, Felipe P., Viana, Diego C., Saraiva, Dennisiane J., Justo, Marcia Cristina N., Cohen, Simone C.
