Progamotaenia capricorniensis sp. nov. (Cestoda: Anoplocephalidae) from wallabies (Marsupialia: Macropodidae) from Queensland, Australia

Progamotaenia capricorniensis sp. nov. (Cestoda: Anoplocephalidae) is described from the wallabies Macropus dorsalis (Gray, 1837) and Petrogale assimilis Ramsay, 1877 from Queensland, Australia. The new species is characterised by a fimbriated velum composed of 26-32 digitiform to triangular projections on each side of the proglottis, paired uteri and 140-190 testes distributed in a single band across the medulla. Minor variation occurs in the distribution of the testes. The above characters distinguish the new species from its most closely related congeners P. lagorchestis (Lewis, 1914), P. proterogyna (Fuhrmann, 1932), P. spearei Beveridge, 1980 and P. villosa (Lewis, 1914). P. capricorniensis appears to exhibit a highly disjunct distribution within its usual host, M. dorsalis.     

Falcaustra kutcheri n. sP. (nematoda: kathlaniidae) from Geoemyda yuwonoi (testudines: emydidae) from Sulawesi, Indonesia

Falcaustra kutcheri n. sp. (Nematoda: Kathlaniidae) from feces of the turtle Geoemyda yuwonoi is described and illustrated. Falcaustra kutcheri n. sp. represents the 68th species to be assigned to this genus and is distinguished from other oriental species by the distribution pattern of caudal papillae of the male: 10 pairs of sessile caudal papillae, 4 pairs precloacal, 1 pair adcloacal, 5 pairs postcloacal.     

Falcaustra washingtonensis n. sp. (Nematoda: Kathlaniidae) from Ambystoma tigrinum melanostictum (Caudata: Ambystomatidae) from Washington State, USA.

Falcaustra washingtonensis n. sp. (Nematoda: Kathlaniidae) from the intestine of the salamander Ambystoma tigrinum melanostictum is described and illustrated. Falcaustra washingtonensis n. sp. represents the 14th nearctic species assigned to this genus and is distinguished from other nearctic species by the distribution pattern of caudal papillae and number of posterior muscle groups of the male: 10 pairs of sessile caudal papillae--3 pairs precloacal, 1 pair adcloacal, 6 pairs postcloacal--and 5 posterior muscle groups.     

Some Eugregarines (Sporozoa, Apicomplexa) from the Stored Fruit Beetle, Oryzaephilus mercator Fauv. (Coleoptera) from India

Morphology and life history of 3 cephaline gregarines found in the gut of the pest of stored fruit, Oryzaephilus mercator. are described. Of these 3, 2 are new species. The 3 species are (1) Hirmocystis minuta (Ishii, 1914) (LP TL = 1:7 – 1:22, WP/WD = 1:1, 6–1:7); (2) Amsotobus indicus n. sp. (LP/TL = 1:3–1:6, WP/WD = 1:1 – 1:1.3); (3) Leidyana oryzaephili n. sp. (LP/TL = 1:2 – 1:12; WP/WD = 1:1–1:1.6).     

Hedruris hanleyae n. sp. (Nematoda: Hedruridae) from Hemidactylus garnotii (Sauria: Gekkonidae) from the Cook Islands, Oceania

Hedruris hanleyae n. sp. (Nematoda: Hedruridae) from the stomach of Hemidactylus garnotii collected in 1989 on Atiu, Cook Islands is described and illustrated. Hedruris hanleyae n. sp. represents the 21st species to be assigned to the genus and is distinguished from other oriental species by the distribution pattern of caudal papillae of the male: 10 pairs posterior subventral papillae; 2 pairs precloacal and 8 pairs postcloacal.     

Two new nematodes from the Iriomote cat, Prionailurus iriomotensis, from Okinawa: Uncinaria (Uncinaria) maya n. sp. (Ancylostomatoidea) and Molineus springsmithi yayeyamanus n. subsp. (Trichostrongyloidea)

Uncinaria (Uncinaria) maya n. sp. (Nematoda: Ancylostomatidae) and Molineus springsmithi yayeyamanus n. subsp. (Nematoda: Molineidae) are described from the Iriomote cat, Prionailurus iriomotensis, on Iriomote Island, Okinawa, Japan. Uncinaria (U.) maya resembles Uncinaria (Uncinaria) felidis Maplestone, 1939, from Prionailurus bengalensis of India but is distinguished in that the body is much smaller, the ventral rays are set closely with the lateral rays, and the externolateral ray is much shorter than other laterals. Molineus springsmithi yayeyamanus differs from Molineus springsmithi springsmithi Inglis and Ogden, 1965, from Prionailurus bengalensis horsfieldi of East Nepal in that the body is much longer, whereas the esophagus is somewhat shorter and the spicules are divided more distally. Presence of the closely related nematodes in both the Iriomote cat and P. bengalensis suggests a close evolutionary relationship of the 2 hosts.     

Sutarostrongylus Johnsoni sp. n. (Nematoda: Trichostrongylina, Heligmosomoidea) from the pademelon, Thylogale stigmatica (Marsupialia) from Queensland, Australia

A new species of heligmosomoid nematode Sutarostrongylus johnsoni sp. n., belonging to the sub-family Herpetostrongylinae Skrjabin & Schultz, is described from the small intestine (duodenum) of the red-legged pademelon, Thylogale stigmatica (Gould, 1860) (Marsupialia: Macropodidae), from north-eastern Queensland, Australia. The only other species of the genus S. kirkpatricki Beveridge & Durelte-Desset, 1986 occurs in the related host, the red-necked pademelon, T. thetis (Lesson, 1827) in south-eastern Queensland. The new species differs in having longer spicules and asymmetrical spicule tips as well as the presence of a comarete which develops on the right ventral aspect of the mid-region of the body. The synlophe of the new species is unusual in that the inclination of the axis of orientation changes from being oblique in the anterior part of the body to being frontal in the posterior part. The same change may occur in some species of Austrostrongylus Chandler, 1924. Current data suggest that species of Sutarostrongylus are limited to a single genus of host, Thylogale Gray, 1837 and support the suggestion that both nematode species exhibit morphological features which are intermediate between those occurring in Herpetotostrongylinae in dasyurid marsupials and those occurring in macropodid marsupials.     

Africana telfordi n. sp. (Nematoda: Heterakidae) from the lizard,Enyalioides heterolepsis (Sauria: Iguanidae) from Panama

Africana telfordi n. sp. (Nematoda: Heterakidae) from the large intestine of the lizard Enyalioides heterolepsis collected in Panama is described and illustrated. Africana telfordi n. sp. represents the seventh species assigned to the genus and the second from the Neotropical Realm. It is distinguished from the other neotropical species, A. chabaudi, by the size and shape of the spicules. The spicules of A. telfordi are robust, analate, and 366-458 microm in length; those of A. chabaudi are narrow, alate, and 644-869 microm in length.     

Paralepidapedon ostorhinchi (Korotaeva, 1974) n. comb. (Digenea: Lepocreadiidae) in Oplegnathus woodwardi (Waite) (Teleostei: Perciformes: Oplegnathidae) from off Rottnest Island,Western Australia

The digenean originally designated Lepidapedon (Lepidapedon) ostorhinchi is redescribed from its type-host, Oplegnathus woodwardi [= Ostorhinchus conwaii], from the waters off Western Australia. The discovery of a uroproct indicates that the generic designation is wrong and the worm should be Paralepidapedon ostorhinchi (Korotaeva, 1974) n. comb. It is distinct from its nearest relative, P. hoplognathi (Yamaguti, 1938), in having: a prominent post-oral ring; a distinct oesophagus; short anterior diverticula on the caeca; a long external seminal vesicle, ensheathed in a membrane bound gland-cell mass; and less anteriorly extensive vitellarium.     

Neodiplostomum spratti n. sp. (Digenea: Diplostomidae) from Antechinus spp. (Marsupialia: Dasyuridae) in Australia,with notes on other diplostomids from Australian mammals

Neodiplostomum spratti n. sp. is described from Antechinus stuartii and A. swainsonii (Marsupialia: Dasyuridae). The status of Neodiplostomum minor, N. flabelliformis, N. intermedius, N. sarcophilus, N. diaboli and Pharyngostomoides dasyuri is reviewed. New hosts records for N. intermedius are Rattus lutreolus, R. leucopus, R. rattus (all Rodentia: Muridae) and Dasyurus maculatus (Dasyuridae). The following undescribed species are recorded: Neodiplostomum spp. from Dasyurus maculatus from Victoria, Dasyurus viverrinus from Tasmania, Perameles nasuta (Marsupialia: Peramelidae) from New South Wales, Sminthopsis leucopus (Dasyuridae) from New South Wales, and a diplostomulum from the lung of Perameles nasuta from New South Wales. The validity of Fibricola is reconsidered and it is proposed that it be considered a synonym of Neodiplostomum. The new combinations Neodiplostomum minor (Dubois, 1936), N. sarcophilus (Sandars, 1957) and N. flabelliformis (Pearson & Dubois, 1985) are proposed: all three were previously attributed to Fibricola.     

Two species of Dioncopseudobenedenia Yamaguti, 1965 (Monogenea: Capsalidae) from Naso unicornis (Forsskål) (Acanthuridae) and Coryphaena hippurus Linnaeus (Coryphaenidae) in western Japan,with a description of D. elongata n. sp. from N. unicornis

Systematic Parasitology - Three species of Dioncopseudobenedenia Yamaguti, 1965 (Monogenea: Capsalidae: Benedeniinae) have been described, all found parasitising Naso spp. (Acanthuridae) and...     

Monogeneans from Pangasiidae (Siluriformes) in Southeast Asia: II. Four new species of Thaparocleidus Jain, 1952 (Ancylodiscoidinae) from Pangasius humeralis.

The examination of gills from two rare endemic species of Pangasius Valenciennes, 1840 (Siluriformes, Pangasiidae): P. humeralis Roberts, 1989 (five specimens) and P. lithostoma Roberts, 1989 (six specimens) from the Kapuas River (West Kalimantan province, Bomeo Island, Indonesia) revealed the presence of four new species of Monogenea belonging to the genus Thaparocleidus Jain, 1952 (Monogenea, Ancylodiscoidinae) on P. humeralis: T. sinespinae n. sp., T. brevicochleus n. sp., T. kapuasensis n. sp. and T. gustianoi n. sp., and not any on P. lithostoma.     

Wakubitinema toyamai n. gen. and n. sp. (Nematoda: Seuratoidea: Quimperiidae) from the intestine of Rana (Limnonectes) Namiyei (Amphibia: Ranidae) on Okinawa Island, Japan

Wakubitinema n. gen. (Nematoda: Seuratoidea: Quimperiidae: Quimperiinae) is erected for Wakubitinema toyamai n. sp. from the small intestine of Rana (Limnonectes) namiyei Stejneger, 1901, on Okinawa Island, Japan. Wakubitinema resembles Paraquimperia Baylis, 1934, and Desmognathinema Baker et al., 1987, but is readily distinguished from the former genus by the distinctly divided esophagus and the absence of cervical flanges and lateral alae, and from the latter genus by the postesophageal position of the excretory pore and cervical papillae and the presence of preanal unpaired papilla in males. Close morphological similarities between Wakubitinema and Paraquimperia may suggest that Wakubitinema has evolved from a quimperiid fish.     

Rallicola deckeri n. sp. (Phthiraptera: Philopteridae) from Ruddy Woodcreepers Dendrocincla homochroa (Passeriformes: Furnariidae) collected in Campeche, Mexico

A new species of Rallicola Johnston and Harrison (Phthiraptera: Philopteridae) is described from lice collected from a series of Ruddy Woodcreepers Dendrocincla homochroa (Aves: Dendrocolaptinae) in Campeche, Mexico. Rallicola deckeri is easily recognized by the unique shape of the mesosome in the male and by the pattern of divided sternites on the female.     

Hysterothylacium simile n. sp. and H. aduncum (Rudolphi, 1802) (Nematoda: Raphidascarididae) from marine fishes in the Bohai and Yellow Sea, China, with comments on the record of H. paralichthydis (Yamaguti, 1941) from Chinese waters

Hysterothylacium simile n. sp., collected from the Japanese seabass Lateolabrax japonicus (Cuvier) (Perciformes: Lateolabracidae) in the Bohai Sea off China, is described using both light and scanning electron microscopy. The new species differs from its congeners in the presence of narrow lateral alae originating a short distance posterior to the base of the ventrolateral lips, a long intestinal caecum (60.4–79.1% of oesophageal length) and a relatively short ventricular appendix (intestinal caecum to ventricular appendix ratio 1:0.58–0.85), long spicules (2.11–2.99 mm, 4.25–7.83% of body length), the number and arrangement of the caudal papillae (32–36 pairs arranged as follows: 27–31 pairs precloacal, 1 pair paracloacal, and 4–5 pairs postcloacal with the second or third pair double) and the presence of a particular midventral precloacal papilla. Specimens originally identified as Contracaecum paralichthydis Yamaguti, 1941 [now H. paralichthydis (Yamaguti, 1941)] by Xü (1957), collected from the yellow striped flounder Pseudopleuronectes herzensteini (Jordan & Snyder) (Pleuronectiformes: Pleuronectidae) in the Yellow Sea off China, were also re-examined. Their morphology clearly revealed they belong to H. aduncum (Rudolphi, 1802), which is also redescribed based on Xü’s material. In addition, the morphological variation of caudal papillae in H. aduncum from P. herzensteini was compared, using scanning electron microscopy, with specimens collected from another three fish hosts, Lophius litulon (Jordan) (Lophiiformes: Lophiidae), Scomberomorus niphonius (Cuvier) (Perciformes: Scombridae) and Cleisthenes herzensteini (Schmidt) (Pleuronectiformes: Pleuronectidae), from the Yellow Sea off China.

All hosts are Central and South American parrots. Mesolichus Trouessart, 1899 is recognized as a monotypical genus.     

Monogeneans from Pangasiidae (Siluriformes) in Southeast Asia: III. Five new species of Thaparocleidus Jain, 1952 (Ancylodiscoididae) from Pangasius bocourti,P. djambal and P. hypophthalmus

The examination of gill parasites from Pangasius bocourti Sauvage, 1880; P. djambal Bleeker, 1846; P. hypophthalmus (Sauvage, 1878) and P. gigas Chevey, 1930 (Siluriformes, Pangasiidae) revealed the presence of seven species of Monogenea among which five are considered new species. They all belong to Thaparocleidus Jain, 1952 (Ancylodiscoididae) as defined by Lim (1996) and Lim et al. (2001). P. bocourti: T. combesi n. sp., T. komarudini n. sp. and T. vietnamensis n. sp. P. djambal: T. caecus (Mizelle & Kritsky, 1969), T. combesi n. sp., T. euzeti n. sp., T. komarudini n. sp. and T. sadilii n. sp. P. hypophthalmus: T. caecus, T. siamensis (Lim, 1990) and T. vietnamensis n. sp. P. gigas: no Monogenea were found on this host species.     

Eimeria turcicus N. Sp. (Apicomplexa: Eimeriidae) from the Mediterranean Gecko, Hemidactylus turcicus (Sauria: Gekkonidae)

ABSTRACT. Eimeria turcicus n. sp. (Apicomplexa: Eimeriidae) is reported from the gall bladder of the Mediterranean gecko, Hemidactylus t. turcicus (Linnaeus, 1758) from the Houston Zoo, Texas, USA. Oocysts of this coccidian are elongate and cylindrical, 38.2 × 17.9 (35.2-40.8 × 16.8-20.0)μm, with a smooth, bilayered wall ∼ 1.6 μm thick; shape index 2.1 (1.9-2.3). A polar granule is present, but a micropyle and oocyst residuum are absent. Sporocysts are ovoid, 11.0 × 8.8 (10.0-12.0 × 8.0-9.4) μm, with a smooth, thin wall and suture; shape index 1.3 (1.1-1.4). Each sporocyst contains a residuum measuring 6.0 × 5.1 (4.8-8.0 × 4.8-6.4) μm, additional residual granules scattered among the sporozoites, and two sporozoites that are normally arranged head-to-tail within the sporocyst. Each sporozoite contains a single, ovoid, posterior refractile body and a central nucleus.     

Progamotaenia ruficola sp. n. (Cestoda: Anoplocephalidae) from the red kangaroo, Macropus rufus (Marsupialia)

Progamotaenia ruficola sp. n. is described from the red kangaroo (Macropus rufus) from New South Wales, Australia. It is distinguished from other similar species having paired, nondiverticulate uteri in each prolottis: Progamotaenia festiva (Rudolphi 1819), P. diaphana (Zschokke 1907), and P. macropodis Beveridge 1976, by the extremely broad, straight-edged velum, the lack of an external seminal vesicle, the cirrus armature, the number of testes, the lack of vaginal atrophy following insemination, and the morphology of the egg.     

Linguaserra spandeli sp. nov. (Echinodermata: Ophiocistioidea) from the Late Permian (Zechstein) of Thuringia, Germany

From the Late Permian Zechstein reefs (Lopingian: Wuchiapingian) of eastern Thuringia, Germany, the new ophiocistioid goniodont Linguaserra spandeli sp. nov., is described, figured, and discussed, within the Linguaserridae Reich and Haude, 2004. The (para)genus Linguaserra is redefined; the stratigraphical and regional distribution as well as the phylogenetic position are briefly discussed. Linguaserra spandeli sp. nov. is the stratigraphically youngest record of this echinoderm group (Echinozoa: Ophiocistioidea) worldwide.
