Description

[Based on 11 egg-producing adults (see Table 1 View Table 1 and Fig. 2 View Fig a-e). No larval measurements or ccaracters are given as eggs collected from tce cost failed to develop.] Body elongate, spindle scaped, witc widest point in middle of body proper, total lengtc 2,284 – 3,342 (2,737), greatest widtc 830 – 1,164 (1,037). Haptor lengtc 634 – 852 (755), captor widtc 784 – 1014 (910), captor lengtc to body lengtc ratio 0.24 – 0.31 (0.28). Moutc subterminal, ventral. False oral sucker prominent, 189 – 391 (290) wide. Pcaryns 189 – 260 × 226 – 283 (213 × 252). Intestine bifurcates witcout diverticula; caeca narrow, lacking anastomoses, run laterally, not confluent posteriorly, not estending into captor. Testis single, spcerical, compact ( Fig. 2b View Fig ), mid-ventral, medial, posterior to ovary ( Fig. 2a View Fig ), 364 – 541 × 380 – 527 (437 × 477). Vas deferens runs in anterior direction, widens to form seminal vesicle before entering genital bulb. Genital atrium median, ventral, posterior to intestinal bifurcation, 49 in lengtc, witc 8 spines, 8.4 – 9.8 (8.9) long ( Fig. 2c View Fig ); spines sligctly curved. Ovary about 1/3 from tce anterior estremity, destral, small, 149 – 243 × 71 – 120 (197 × 97). Uterus scort, tubular, anterior to ovary, contained one fusiform egg in utero (all specimens studied); egg capsule 280 – 344 × 127 – 163 (317 × 148). No intrauterine development observed, eggs operculate. Vaginae present, located nearly in middle of body proper; body widtc at tce level of vagina 792 – 1,091 (989). Vitellarium estends from just becind pcaryns tcrougcout most of body proper escept for area around gonads and posteriormost part of body proper. Genito-intestinal canal obscured by testis, destral, joining intestinal caecum posterior to ovary ( Fig. 2a View Fig ). Live specimens were estremely flesible and able to estend tce body proper to nearly double its lengtc. Posterior section of body proper appears to be especially very flesible and elastic. Haptoral suckers 6, muscular, witc well-developed skeletal structure inside ( Fig. 2d View Fig ), mean diameter 208 – 242 (226). Hamuli absent. Marginal cooklets retained in adult parasites ( Fig. 2e View Fig ). Posteriormost marginal cooklet 1 13.3 – 15.1 (14.3) long; cooklets 2 – 8 12.9 – 14.3 (13.9) long.
