Remarks. The redescription of this species is based exclusively upon specimens from Macropus giganteus , identified by Rudolphi (1819) as the host of the type specimens. The type specimens were collected from a grey kangaroo, M. giganteus , which died in the Schönbrunn Zoological Gardens, Vienna, and were collected by Bremser and sent to Rudolphi in Berlin. Putting aside the reliability of the identification of species of Macropus in European zoos during the early nineteenth century, the genetic study of Beveridge et al. (2007), based on the cox 1 gene, indicated that specimens of bile duct cestodes collected from this host species over a broad geographical range in eastern Australia belonged to the same genetic clade and therefore potentially to the same species. A wide range of specimens was also available from this host species covering most of its geographical range ( Fig. 12) and all were relatively uniform morphologically. The cestodes were long (> 150 mm), composed of> 400 segments, with the first mature segment being about the 170–205th segment from the scolex. The scolex was usually prominently four-lobed ( Fig.3), though in incompletely relaxed specimens, the lobes of the scolex were shortened ( Fig.2). In the mature segments, the testes were almost invariably separated into two equal groups, with 71–93 testes per segment, and the testis fields abutted the longitudinal osmoregulatory canals. The cirrus sac was small and reached the osmoregulatory canals but rarely extended significantly into the medulla ( Fig. 8). The external seminal vesicle was spirally coiled and was surrounded by gland cells; when filled, several coils were expanded, giving the appearance of a multichambered external seminal vesicle ( Fig. 5).

Specimens of P. festiva from M. rufus formed a distinctive clade in the genetic analysis of Beveridge et al. (2007). Morphologically, these specimens (with a single exception dealt with below) were also uniform throughout their geographic range ( Fig. 14), and were similar to the specimens from M. giganteus , differing only in the more pronounced extension of the cirrus sac into the medulla in some specimens ( Fig. 9). However, there was substantial variation in this feature within specimens from M. rufus and there was no difference in the mean size of the cirrus sac between specimens from M. giganteus and M. rufus (Table 1). Consequently, no significant and consistent morphological differences were observable between specimens from these two host species. Collections from M. rufus were relatively extensive, but were concentrated in the eastern part of the host range ( Fig. 14). Additional collecting is required in central and western Australia to ensure that the genetic clade is uniform across its entire range.

In the genetic analysis, all specimens from M. parryi also formed a distinctive clade. Morphologically, these specimens, which were obtained from across a wide geographical range ( Fig.13), were relatively uniform morphologically, but differed in one feature. In almost all specimens, the external seminal vesicle was fusiform ( Fig. 6) rather than spirally coiled. The testes were in separate groups, a feature of all specimens in this group, except for two specimens, one of which was immature (SAM 29414) and the other was severely contracted (SAM 20069). In all well-preserved specimens examined, there was a distinctive space between the osmoregulatory canals and the lateral extent of the testis fields ( Fig. 10), thereby distinguishing these specimens from those found in M. giganteus and M. rufus .

Specimens from M. robustus and M. antilopinus occurred in four distinct clades in the genetic analysis of Beveridge et al. (2007), and these differences were reflected in part in their morphological features. Specimens collected from M. robustus in South Australia and Western Australia (type 1 in Fig. 15) were morphologically identical with those from M. giganteus and M. rufus in lacking a space between the testis field and the osmoregulatory canals. Specimens from M. robustus from north western Queensland (Mt Isa, Cloncurry) (type 2 in Fig. 15) were distinguishable in having a distinct space between the osmoregulatory canals and the testis fields as in the specimens from M. parryi ( Fig. 10), but were distinguishable from specimens in M. parryi in having a spiral external seminal vesicle. This clade was also found in M. dorsalis in north-eastern Queensland and in M. rufus from Cloncurry and Pentland, Queensland, but in each case, this genetic form was identifiable by the space between the testes and the osmoregulatory canals and by the spiral external seminal vesicle. Specimens with similar morphological features were seen in M. robustus from Armidale, NSW, Barrow Island and the Kimberley, WA, but since no material was available from these locations for genetic analysis, the relationships of these cestodes remain to be delineated. The genetic clade (3 in Fig. 15) identified from coastal north-eastern Queensland was characterised morphologically by the lack of a space between the testis fields and the osmoregulatory canals and was therefore not distinguishable from the clade found in south and western Australia (1 in Fig. 15).

All material examined from M. antilopinus in the Northern Territory and all but one specimen examined from Queensland was morphologically distinctive in having a distinct space between the osmoregulatory canals and the testis fields and a greater number of testes per segment than in other specimens ( Fig. 11) (Table 1). However, the space between testis fields and osmoregulatory canals was somewhat variable and was small in one specimen. This morphological form was also seen in a single M. robustus from the Northern Territory, in an area in which M. antilopinus and M. robustus are sympatric (4 in Fig. 15). No entire specimens of this morphotype were collected and therefore although it appears to represent a distinctive species, it is not described as a new species herein. In the Mt Surprise region of northern Queensland, M. antilopinus and M. robustus are also sympatric ( Fig. 15). The fixed material from M.antilopinus from this area is similar to that from the same host species in the Northern Territory. However, the single specimen of P. festiva from M. antilopinus from north Queensland used in the genetic analysis appears to be identical with the morphological form predominant in M. robustus in that region suggesting that both morphotypes may occur in the two host species in this region. More extensive collections are needed to resolve the morphotypes present in wallaroos in this region.

Metric data of P. festiva from various host species are presented in Table 1. Whilst there are some differences in measurements, particularly for specimens designated as clade 4, initial inspection of the data suggested that detailed statistical analysis was not warranted as it was unlikely to yield useful taxonomic information.

Fragmentary material was available from Onychogalea unguifera from the Kimberley region of Western Australia. While generally referable to P. festiva , additional specimens are required to determine if it represents an additional species.
