BOLETTE University of Pittsburgh, Division of Laboratory Animal Resources, S1040 Biomedical Science Tower, Pittsburgh, Pennsylvania 15261, U.S.A. (e-mail: dbolette@vms.cis.pitt.edu) ABSTRACT: Cystacanths of Mediorhynchus orientalis Belopol'skaya and 1 cystacanth of Mediorhynchus wardi Schmidt and Canaris were collected from opportunistically infected Surinam cockroaches, Pycnoscelis surinamensis (Linnaeus), at the National Aviary in Pittsburgh, Pennsylvania, U.S.A. Morphological Copyright © 2011, The Helminthological Society of Washington measurements and descriptions of Cystacanths of M. orientalis and M. wardi are provided for the first time. KEY WORDS: Mediorhynchus orientalis, Mediorhynchus wardi, Acanthocephala, Gigantorhynchidae, Cystacanths, Surinam cockroach, aviary, description, Pennsylvania, U.S.A.
Mediorhynchus orientalis Belopol'skaya, 1953 was originally described from juvenile specimens collected from a little ringed plover, Charadrius duhius curonicm Gmelin, 1789, in Russia. Schmidt and Kuntz (1977) subsequently redescribed the species from numerous adults and juveniles collected from 10 species of passeriform birds and a Pacific golden plover, Pluvialis fulva (Gmelin, 1789); (as Charadrius dominions fulvus), from Taiwan, Borneo, and Hawaii. Mediorhynchus wardi Schmidt and Canaris, 1967 was described from numerous adult specimens collected from 4 species of passeriform birds in Njoro, Kenya. Forty-five species of Mediorhynchus were recorded as valid in Amin's (1985) list of Acanthocephala. Two additional species not included in Amin's list were apparently described during its preparation (George and Nadakal, 1984). Five of these have the cystacanths described. Cystacanths of Mediorhynchus petrochenkoi Gvosdev and Soboleva, 1966, were described by Lisitsina and Tkach (1994); of Mediorhynchus centurorum Nickol, 1969 by Nickol (1977); and of Mediorhynchus grandis Van Cleave, 1916 by Moore (1962). Brief descriptions of the cystacanth stage of Mediorhynchus papillosus Van Cleave, 1916, were provided by Ivashkin and Shmitova (1969) and Gafurov (1975), and of Mediorhynchus micracanthus (Rudolphi, 1819) Meyer, 1933 by Rizhikov and Dizer (1954). Cystacanths of Mediorhynchus orientalis were reported from opportunistically infected Surinam cockroaches, Pycnoscelis surinamensis (Linnaeus, 1758) (Blaberidae) at the National Aviary in Pittsburgh, Pennsylvania, U.S.A. (Bolette, 1990). These cockroaches occurred within a free-flight exhibit that housed a variety of birds originating from various geographical localities. This method of housing most likely contributed to the accidental introduction of M. orientalis into the enclosure. The following description of M. orientalis cystacanths is based on 9 everted specimens, 1 male and 8 females, collected from the coelomic cavities of infected P. surinamensis from the previous report (Bolette, 1990). Additionally, while reexamining the cystacanths previously recovered from Surinam cockroaches (Bolette, 1990), 1 specimen was determined to be M. wardi. The following description of M. wardi is based on this single everted female cystacanth. This report represents the BOLETTE—RESEARCH NOTES 115 first description of M. orientalis and M. wardi cystacanths. The cockroaches were killed with ethyl acetate. Cystacanths were mechanically excysted, placed in refrigerated tap water to elicit proboscis evagination, killed and preserved in AFA fixative, and later transferred to 70% ethyl alcohol. Selected specimens were stained in borax-carmine, dehydrated in ascending concentrations of ethyl alcohol, cleared in ascending concentrations of xylene, and mounted in Permount® (Fisher Scientific, Fairlawn, New Jersey, U.S.A.). Voucher specimens were deposited in the United States National Parasite Collection, Beltsville, Maryland (USNPC No. 88032). Measurements are in jxm unless stated otherwise, with means in parentheses. Trunk measurements do not include the neck. Hook and spine measurements were determined in complete profile. Mediorhynchus orientalis Belopol'skaya, 1953 GENERAL (CYSTACANTH): Trunk short, oblong, slightly tapered at distal end. Proboscis truncate, conical (Fig. 1). Proboscis armature similar in both sexes. 19-24 (usually 20-21) nearly longitudinal rows of 4-6 (usually 5) hooks each. Anterior 2—3 hooks 37.5—50.0 (47.3); middle 2-3 hooks 37.5-45.0 (40.7); posterior 1-2 hooks 20.0-40.0 (29.2). Rootless spines arranged in 34—38 rows of 3-6 (usually 4-5) spines each; 27.5-45.0 (36.75) long. Lemnisci long, slender, usually folded, and partly retained in neck region and anterior part of trunk. FEMALE CYSTACANTHS (based on 8 specimens): Trunk 1.49-1.89 (1.66) mm long, 0.48-0.73 (0.58) mm wide at widest point. Proboscis 637— 726 (695) long. Anterior proboscis 398-458 (428) long, 308-338 (318) wide at base. Posterior proboscis 199-348 (272) long, 289-398 (350) wide at base. Neck 131-192 (158) long, 364-455 (391) wide at base. Sensory pit 27.5- 30.0 (24.0) long, 27.5-45.0 (35.0) wide, located 22.5-140 (87.0) distal to posteriormost spine. MALE CYSTACANTH (1 specimen): Trunk 1.59 mm long, 0.62 mm wide at widest point. Proboscis 662 long. Anterior proboscis 384 long, 283 wide at base. Posterior proboscis 278 long, 318 wide at base. Neck 167 long, 333 wide at base. Sensory pit 22.5 long, 30.0 wide, located 17.5 distal to posteriormost spine. Copyright © 2011, The Helminthological Society of Washington
