“…Of the other small congeners, A. martini is most similar to A. minusculum (see Marques et al 1997a) from Urolophus tumbesensis from Ecuador in hook and locular length ratios, size and testis number but has hooks of a different form, a submarginal and more posterior genital pore, a larger cirrus sac and an H-shaped ovary with lobes extending to the cirrus sac. Acanthobothrium martini differs from A. tripartitum from Britain in possessing fewer testes per segment (8-11 v. 13-16) and more segments (9-13 v. 3).…”

“…Of the species reported from Dasyatis longus from Pacific coastal waters of Costa Rica (Marques et al 1995(Marques et al , 1997a, A. campbelli is very similar to A. lasti but A. lasti differs in having an average of equal numbers of prevaginal (4.3) and post-vaginal testes (4.1) versus an average of six and three for the same regions in A. campbelli, a posterior instead of an anterior curvature of the cirrus sac, more anterior position of the genital pore (33-38% of segment length v. 41-50%) and lack of a vaginal sphincter (present in A. campbelli). Acanthobothrium lasti differs from all other congeners in its combination of the ratio of locular lengths, testis number and distribution, position of the genital pore, presence of a vaginal sphincter, total hook length and hook form.…”

“…Compared with species reported from urolophids in other parts of the world, A. odonoghuei is further distinguished by testis number from A. parviuncinatum (12-14 v. 31-34) of Young (1954); from A. olseni of Dailey and Mudry (1968) by the position of the genital pore (pre-equatorial v. post-equatorial) and the length of ovarian lobes (to level of genital pore v. well separated from cirrus sac) (see Ghoshroy and Caira 2001 for new host record); from A. cartagenense of Brooks and Mayes (1980) by the position of the genital pore (34-38% of segment length v. 49-53%) and testis number (21-26 v. 31-34); from A. minusculum of Marques et al (1997a) by testes number (6-10 v. 31-34) and position of the genital pore (10-37% of segment length v. 49-53%); from A. crassicolle (see Young, 1954) and A. dasybati of Yamaguti (1934) by size (80 mm, 52 mm v. 2.9 mm) and testis number (100-153, 40-70 v. 31-34); and from A. dujardini by total hook length (180-210 v. 72-86) and absence of a vaginal sphincter (present in A. dujardini).…”

The onchobothriid tetraphyllidean cestode genus Acanthobothrium van Beneden, 1849, parasitic in the spiral intestine of elasmobranch fishes, was investigated in the Australian region. Thirty-three species are recognised, including 27 that are new. Diagnoses compare the morphological taxonomic characters of all congeners. New species are: Acanthobothrium adlardi; A. angelae; A. arlenae; A. bartonae; A. blairi; A. brayi; A. cannoni; A. chisholmae; A. clarkeae; A. cribbi; A. edmondsi; A. gasseri; A. gibsoni; A. gloveri; A. jonesi; A. lasti; A. laurenbrownae; A. martini; A. mooreae; A. ocallaghani; A. odonoghuei; A. pichelinae; A. robertsoni; A. rohdei; A. stevensi; A. thomasae; and A. walkeri. Additional morphological data are provided for A. australe Robinson, 1965, A. pearsoni Williams, 1962, A. heterodonti Drummond, 1937 and A. urolophi Schmidt, 1973, reported previously from Australia. Acanthobothrium rhynchobatidis Subhapradha, 1955 and A. semnovesiculum Verma, 1928 are reported from Australia for the first time and are redescribed. Additional morphological details are provided for A. ijimae Yoshida, 1917 and A. grandiceps Yamaguti, 1952. Acanthobothrium wedli Robinson, 1959 is redescribed from the type host from New Zealand waters and considered a sister species of A. blairi from Tasmania. Seven new host genera for Acanthobothrium are reported: Hypnos Duméril, 1852 (Hypnidae); Pristiophorus MÜller & Henle, 1837 (Pristiophoridae); Sutorectus Whitley, 1939 (Orectolobidae); Aptychotrema Norman, 1926 and Trygonorrhina MÜller & Henle, 1838 (Rhinobatidae); Parascyllium Gill, 1862 (Parascylliidae); and Aetomylaeus Garman, 1908 (Myliobatididae). Species of Acanthobothrium are reported from the families Hypnidae, Pristiophoridae and Parascylliidae for the first time. New host species for Acanthobothrium are: Pristiophorus cirratus (Latham, 1794); Parascyllium ferrugineum McCulloch, 1911; Sutorectus tentaculatus (Peters, 1865); Aptychotrema vincentiana (Haacke, 1885); Trygonorrhina fasciata MÜller & Henle, 1841; Raja whitleyi Iredale, 1938; Raja cerva Whitley, 1939; Hypnos monopterygium (Shaw & Nodder, 1795); Dasyatis annotata Last, 1987; Urolophus cruciatus (Lacépède, 1804); Urolophus expansus McCulloch, 1916; Urolophus lobatus McKay, 1966; Urolophus paucimaculatus Dixon, 1969; Gymnura australis (Ramsay & Ogilby, 1886); Aetomylaeus nicofii (Schneider, 1801); and Myliobatis australis Macleay, 1881 (Myliobatididae). New host records for Australia include the above 16 elasmobranch species and the following three host species also known to harbour Acanthobothrium in other geographic localities: Rhynchobatis djiddensis (Forsskål, 1775) (Rhynchobatidae); Himantura uarnak (Forsskål, 1775); and Pastinachus sephen (Forsskål, 1775) (Dasyatidae). Four additional records for hosts previously reported for Acanthobothrium from Australian waters are Squalus megalops (Macleay, 1881) (Squalidae), Heterodontus portusjacksoni (Meyer, 1793) (Heterodontidae), Orectolobus maculatus (Bonnaterre, 1788) (Orectolobidae) and Trygonoptera ‘testacea’ MÜller & Henle, 1841 (Urolophidae). An emended diagnosis of the genus, key to Australian species, host-parasite checklist, phylogenetic analysis of the Australian species and an updated world list of all species of Acanthobothrium are provided.

A new species of Acanthobothrium van Beneden, 1850 (Tetraphyllidea: Onchobothriidae) from Pastinachus atrus (Macleay) (Batoidea: Dasyatidae) in Australian waters, with a reassessment of the host associations of Acanthobothrium spp. parasitising Pastinachus spp.

A new Category 1 species of Acanthobothrium van Beneden, 1850 is described from the cowtail stingray Pastinachus atrus (Macleay) collected from the Gulf of Carpentaria near Weipa, Queensland, Australia. This species is unique among Acanthobothrium Category 1 species in that it retains gravid proglottids on its strobila. It differs further from the 34 other Category 1 species in total length, proglottid number and testis number. The host identities of other Acanthobothrium species reported from Pastinachus are revised based on recent taxonomic work on rays of this genus. Given the revised host taxonomy, according to which P. atrus is the only member of its genus occurring off Australia, this should be considered to be the fifth species of Acanthobothrium reported from this Australian endemic species.
