116 COMPARATIVE PARASITOLOGY, 67(1), JANUARY 2000 Figures 1, 2. Everted cystacanths of Mediorhynchus recovered from Surinam cockroaches, Pycnoscelis surinamensis. 1. Proboscis of M. orientalis', bar == 200 jmm. AP, anterior proboscis; BPPN, borderline between posterior proboscis and neck; N, neck; PP, posterior proboscis; RAPP, ridge between anterior and posterior proboscis. 2. Female M. wardi; bar = 250 jjim. GP, gonopore; L, lemniscus; LS, ligament strand; SP, sensory pit, U, uterus; V, vagina. Mediorhynchus wardi Schmidt and Canaris, 1967 FEMALE CYSTACANTH (1 specimen): Trunk short, subglobose, rounded at distal end (Fig. 2), 1.89 mm long, 0.63 mm wide at widest point. proboscis 468 long, 402 wide at base. Posterior proboscis 250 long, 409 wide at base. 25 nearly longitudinal rows of 7-8 hooks each. Anterior 2-3 hooks 32.5-37.5 (36.3); middle 2-3 hooks 27.5-30.0 (29.6); posterior 2 hooks 22.5-30.0 Proboscis truncate, conical, 718 long. Anterior (25.6).

4-5 spines each: 25.0-35.0 (31.4). Neck 202 long, 343 wide at base. Sensory pit 25.0 long, 32.5 wide, located 125 distal to most posterior spine. Lemnisci long, slender, partly folded, extended far into trunk. The proboscis armature arrangement of M. orientalis cystacanths is identical to that of adults of this species as redescribed by Schmidt and Kuntz (1977). However, the proboscis armature and neck measurements of the cystacanths examined differed from those of adults in the following respects. The lengths of the middle 2-3 and posterior 1-2 hooks of cystacanths were 37.5-45.0 and 20.0-40.0, respectively, while those listed for adults were 34-42 and 30-44 (Schmidt and Kuntz, 1977). The neck length and width of female cystacanths and the neck width of the male measured 131—192 by 364-455 and 333, respectively; the measurements of adult females and males were reported as 216—240 by 530-600 and 500-535, respectively. The proboscis of the male cystacanth was slightly longer at 662, while the proboscides of adult males were 500-600 long. The proboscis hook and spine length measurements of the cystacanth of M. wardi differed slightly from those given for adults of this species by Schmidt and Canaris (1967). Cystacanth hook and spine length measurements ranged from 22.5-37.5 and 25.0-35.0, respectively, while those listed for adult M. wardi were 31.0— 36.0 and 21.0-28.0. The proboscis width of the cystacanth was slightly narrower than in adults; anterior and posterior proboscis width for the cystacanth measured 402 and 409, respectively, while the corresponding measurements reported for adults were 425 and 515-545. Neck length of the cystacanth was slightly longer than adults, measuring 202, while the reported adult neck length was 165. Additionally, the cystacanth did not show any evidence of an anterior trunk BOLETTE—RESEARCH NOTES 117 swelling, as described for adults. However, because the armature arrangement and all other proboscis measurements are consistent with those described by Schmidt and Canaris (1967) for adult M. wardi, the single female specimen was assigned to this species.
