Boegeriella nom. nov. (Monogenoidea: Dactylogyridae) for Walteriella Mendoza-Palmero,Mendoza-Franco,Acosta & Scholz, 2019, a junior homonym of Walteriella Kazantsev, 2001 (Coleoptera: Cantharidae)

Walteriella Mendoza-Palmero, Mendoza-Franco, Acosta & Scholz, 2019 was found to be a junior homonym of Walteriella Kazantsev, 2001 (Coleoptera: Cantharidae), also known as soldier beetles, and is replaced by Boegeriella nom. nov. (Dactylogyridae). The two species originally included into the genus, Walteriella conica Mendoza-Palmero, Mendoza-Franco, Acosta & Scholz, 2019 (type-species) and Walteriella ophiocirrus Mendoza-Palmero, Mendoza-Franco, Acosta & Scholz, 2019, are transferred as Boegeriella conica (Mendoza-Palmero, Mendoza-Franco, Acosta & Scholz, 2019) n. comb. and Boegeriella ophiocirrus (Mendoza-Palmero, Mendoza-Franco, Acosta & Scholz, 2019) n. comb.

     

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.     

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.     

Parapharyngodon riojensis n. sp. (Nematoda: Pharyngodonidae) from the lizard Phymaturus punae (Squamata: Iguania: Liolaemidae) from northwestern Argentina

Two hundred and forty-four specimens of Parapharyngodon riojensis n. sp. were found in the large intestines of 2 adult lizards Phymaturus punae collected from Quebrada del Leoncito, Province of La Rioja, Argentina. Parapharyngodon riojensis n. sp. represents the ninth species of the genus from the Neotropical Realm and the first species to be described from Argentina. It can be distinguished from all species of Parapharyngodon on the basis of the morphology of the anterior cloacal lip, the location of the ovary, and geographical distribution. Parapharyngodon riojensis n. sp. is most similar to P. senisfaciecaudus in that the ovary does coil around the esophagus and the number and location of caudal papillae in the males are the same. These 2 species differ in that the eggs of P. senisfaciecaudus are slightly asymmetrical, with a smooth, thin shell, whereas the eggs of P. riojensis are oval, with a punctate thick shell. In addition, the cloacal lip of males of P. senisfaciecaudus is smooth, whereas the cloacal lip of males of P. riojensis is echinate. A key to the species of Parapharyngodon in the Neotropical Realm is provided.     

Leucocytozoon muscicapa n. sp. (Leucocytozoidae: Apicomplexa) from the pied flycatcherFicedula hypoleuca (Pallas) (Passeriformes: Muscicapinae)

Leucocytozoon muscicapa n. sp. is described from the pied flycatcherFicedula hypoleuca (Pallas) (Passeriformes: Muscicapinae) from Finland and compared with other leucocytozoids of the family Muscicapidae.     

Dactylomyza gibsoni n. g., n. sp. (Digenea: Opecoelidae) from Schuettea woodwardi (Waite) (Monodactylidae) from off Western Australia

An opecoelid digenean, Dactylomyza gibsoni n. g., n. sp. is described and figured from Schuettea woodwardi (Waite), a monodactylid from off the coast of Western Australia. The new genus conforms to the concept of the opecoelid subfamily Opecoelinae. The resemblance of the new genus to three other opecoelid genera, Pseudopecoeloides Yamaguti, 1940, Opecoeloides Odhner, 1928 and Poracanthium Dollfus, 1948, is discussed. Dactylomyza n. g. is distinguished from these morphologically similar worms on the basis of its median genital pore, ventral sucker appendages, uroproct and the absence of an accessory sucker. Pseudopecoeloides equesi Manter, 1947 is transferred to the new genus as Dactylomyza equesi (Manter, 1947) n. comb.     

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.     

Acanthocephalus saurius n. sp. (Acanthocephala: Echinorhynchidae) and other helminths from the lizard Norops limifrons (Sauria: Polychrotidae) from Costa Rica

Acanthocephalus saurius n. sp. from the small intestine of Norops limifrons collected in Costa Rica is described and illustrated. Acanthocephalus saurius n. sp. represents the third acanthocephalan species in which gravid individuals have been found in lizard hosts. In addition to A. saurius; 1 species of Trematoda, Mesocoelium monas; 3 species of Nematoda, Piratuba digiticauda, Strongyluris panamaensis, and Acuariidae gen. sp. (larvae in cysts) were found.     

Spauligodon ovifilus n. sp. (Nematoda: Pharyngodonidae) and other helminths from Diplodactylus stenodactylus (Reptilia: Gekkonidae) from Australia

Spauligodon ovifilus n. sp. (Nematoda: Pharyngodonidae) from the large intestines of the gecko Diplodactylus stenodactylus is described and illustrated. Prevalence of infection was 50% (mean intensity 5.9 +/- 6.3, range 1-21). Spauligodon ovifilus n. sp. represents the thirty-fifth species to be assigned to this genus and is distinguished by the extremely long filament of the egg. This is the first report of species of Spauligodon from Australia. In addition, 1 gecko harbored 1 female of Wanaristrongylus papangawurpae, a new host record; 1 gecko harbored 1 encapsulated larva of Abbreviata sp. Review of species assigned to Spauligodon caused the reclassification of Spauligodon azerbajdzanicus to Skrjabinodon azerbajdzanicus n. comb.     

Rhabdias anolis n. sp. (Nematoda: Rhabdiasidae) from the lizard,Anolis frenatus (Sauria: Polychrotidae), from Panama

Rhabdias anolis n. sp. from the lungs of Anolis frenatus collected in Panama is described and illustrated. Rhabdias anolis n. sp. represents the 45th species assigned to the genus and the ninth from the Notropical Realm. It is distinguished from all other Neotropical species by the presence of a pair of sessile lateral papillae on its tail.     

Cryptosporidium fayeri n. sp. (Apicomplexa: Cryptosporidiidae) from the Red Kangaroo (Macropus rufus)

The morphology and infectivity of the oocysts of a new species of Cryptosporidium from the faeces of the red kangaroo (Macropus rufus) are described. Oocysts are structurally indistinguishable from those of Cryptosporidium parvum. Oocysts of the new species are passed fully sporulated, lack sporocysts, and measure 4.5-5.1 microm (mean=4.9) x 3.8-5.0 microm (mean=4.3 microm) with a length to width ratio 1.02:1.18 (mean 1.14) (n=50). Oocysts were not infectious for neonate ARC Swiss mice. Multi-locus analysis of numerous unlinked loci demonstrated this species to be distinct (90.64%-97.88% similarity) from C. parvum. Based on biological and molecular data, this Cryptosporidium infecting marsupials is proposed to be a new species Cryptosporidium fayeri n. sp.     

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.     

Cordonema n. g. (Cosmocercoidea: Kathlaniinae) from the salamander Cryptobranchus allegheniensis (Cryptobranchidae) of North America

Summary Falcaustra mackini (Walton, 1941) is redescribed. The anterior extremity is shown to be supported by three cordons arising from between the lips; the two subdorsal cordons are always curved on to the dorsal lip, whereas the ventral cordon curves on to either the right or left subventral lip. This cephalic morphology differs markedly from Falcaustra sensu stricto. F. mackini is designated type of Cordonema n. g. (Kathlaniinae). Cordonema cryptobranchi (Walton, 1930) n. comb. and C. variabilis (Walton, 1941) n. comb., both occurring in Cryptobranchus allegheniensis, the host for C. mackini, are included in the new genus. ac]19801207     

Rugonema labiatum n. g., n. sp. (Nematoda: Strongyloidea) from the stomach of Macropus irma (Marsupialia: Macropodidae) from Western Australia

Rugonema labiatum n. g., n. sp. is described from the stomach of Macropus irma (Jourdan) from Western Australia. The new genus possesses four branches to the dorsal ray, has a cylindrical buccal capsule and lacks a cervical groove, placing it within the subfamily Cloacininae Stossich, 1899. The presence of a prominently striated buccal capsule and labial as well as cephalic collars places the genus within the tribe Pharyngostrongylinea Popova, 1952, but it is distinguished from all existing genera within the tribe by the possession of four lips. The presence of lips is an important characteristic of the related tribe Zoniolaiminea (Popova, 1952) and the characters used in distinguishing these two tribes are discussed.     

Eimeria tahamensis N. sp. (Apicomplexa: Eimeriidae) from the Arabian quail (Coturnix delegorguei arabica)

Eimeria tahamensis n. sp. is described from the harlequin quail (Coturnix delegorguei arabica) from Tahama, Saudi Arabia. The sporulated oocysts of E. tahamensis n. sp. are ellipsoid, 36.5-42 X 25.5-29 (41.2 +/- 1.34 X 28.4 +/- 0.81) micron, with a thick two-layered wall and one polar granule but without a micropyle or an oocyst residuum. The sporocysts are ovoid, 14-16 X 9-11.5 (15.3 +/- 0.7 X 10.8 +/- 0.64) micron, with a knob-like Stieda body and sporocyst residuum, but without a substiedal body. The sporozoites are often located transversely at the two ends of the sporocysts. The host bird belongs to the order Galliformes.     

Raphidascaris (Sprentascaris) lanfrediae sp. nov. (Nematoda: Anisakidae) from the fish Satanoperca jurupari (Osteichthyes: Cichlidae)

Raphidascaris (Sprentascaris) lanfrediae sp. nov. is described from the intestine of the freshwater fish Satanoperca jurupari (Heckel) (Cichlidae) from the Guamá River, state of Pará, Brazil. The prevalence in fish (n = 59) was 27% with intensity of one-124 (mean 16) nematodes per fish. The new species is characterized mainly by the markedly larger size of ventricular appendix in relation to the oesophagus, presence of short male caudal alae, 14-16 subventral pairs of preanal papillae and six pairs of postanal papillae.     

Amphicreadium n. g. (Digenea: Lepocreadiidae) from monacanthid fishes (Tetraodontiformes) from the coast of northern Tasmania

A new lepocreadiid genus, Amphicreadium, is erected for the species A. denspeniculus n. sp. from Acanthaluteres vittiger and for an unnamed species from Meuschenia freycineti, both from off northern Tasmania. The new genus is distinguished from all other members of its family by its amphistomatous body plan.     

Sympatric species of Deretrema Linton, 1910: D. combesae n. sp. and D. combesorum n. sp. (Digenea: Zoogonidae) from the manybar goatfish Parupeneus multifasciatus (Quoy & Gaimard, 1824) (Perciformes: Mullidae) from New Caledonia

Two sympatric species of Deretrema, D. combesae n. sp. and D. combesorum n. sp. are described from the manybar goatfish Parupeneus multifasciatus from off New Caledonia, South Pacific. D. combesae n. sp. does not fit any of the described Deretrema subgenera. The combination of the characters, tegumental spines, caeca reaching past the testes, the vitellarium reaching into the hindbody, much of the uterus at the level of and anterior to the gonads, a long oesophagus, testes in the hindbody and the pre-testicular ovary are not found in any of the described subgenera. D. combesorum n. sp. fits into the subgenus Deretrema (Deretrema), but differs from the described species in the sucker-ratio, eggs size, elongate shape and contiguous testes. The sympatry of these dissimilar species of Deretrema casts doubt on the value of the subgenera in Deretrema.     

Empruthotrema dasyatidis n. sp. (Monogenea: Monocotylidae) from the olfactory sacs of Dasyatis fluviorum (Rajiformes: Dasyatidae) from Moreton Bay,Queensland

The monocotylid monogenean Empruthotrema dasyatidis n. sp. is reported from the olfactory sacs of the brown stingray, Dasyatis fluviorum Ogilby, 1908, from Moreton Bay, Queensland, Australia. This is the first record of Empruthotrema from the family Dasyatidae. E. dasyatidis n. sp. differs from other species of Empruthotrema by possessing eye pigment, which may be scattered, and by its small size. The generic diagnosis for Empruthotrema is amended.     

Coccidian parasites (Apicomplexa: Eimeriidae) from insectivores. II. Six new species from Japanese shrew moles (Talpidae)

Thirty-eight of 51 (74.5%) shrew moles collected in Japan were infected with from one to four species of Eimeria and/or Isospora including six of six Dymecodon pilirostris and 32 of 45 (71.1%) Urotrichus talpoides. Four eimerians and two isosporans were identified and all are described as new species. Sporulated oocysts of Eimeria amorphospora n. sp. were subspheroid/ellipsoid, 21.1 x 17.9 (18-25 x 16-21) micrometers. Sporocysts were amorphous, gelatinoid envelopes greater than or equal to 20.3 x 7.5 (17-24 x 7-9) micrometers. Sporozoites were enclosed together within a membrane in each sporocyst. This species was found in 9 of 45 (20%) U. talpoides. Sporulated oocysts of Eimeria gonocilia n. sp. were subspheroid/ellipsoid, 28.8 x 24.4 (25-30 x 21-28) micrometers; a highly ornate outer oocyst wall gave the appearance of a ciliated ball. Sporocysts ovoid, pointed at both ends, were 17.0 x 9.9 (15-19 x 7-11) micrometers; this species was found in 4 of 45 (8.9%) U. talpoides. Sporulated oocysts of Eimeria talpoidei n. sp. were asymmetrical ovoid, 20.6 x 13.3 (18-23 x 12-15) micrometers, with sporocysts lacrimiform, 12.0 x 5.8 (10-14 x 5-7) micrometers. This species was found in 7 of 45 (15.6%) U. talpoides. Sporulated oocysts of Eimeria honshuensis n. sp. were ellipsoid, 15.5 x 11.4 (13-18 x 10-13) micrometers, with sporocysts ovoid, 9.1 x 5.2 (8-10 x 4-6) micrometers. This species was found in 10 of 45 (22.2%) U. talpoides and in 5 of 6 (83.3%) D. pilirostris. sporulated oocysts of Isospora dymecodi n. sp. were subspheroid/ellipsoid, 15.8 x 12.6 (13-17 x 11-13) micrometers, with sporocysts ovoid, 9.1 x 5.2 (8-10 x 4-6) micrometers. This species was found in 10 of 45 (22.2%) U. talpoides and in 5 of 6 (83.3%) D. pilirostris. Sporulated oocysts of Isospora dymecodi n. sp. were subspheroid/ellipsoid, 15.8 x 12.6 (13-17 x 11-13) micrometers, with sporocysts ellipsoid, 10.9 x 6.9 (10-13 x 6-8). This species was found in six of six D. pilirostris. Sporulated oocysts of Isospora urotrichi n. sp. were spheroid/subspheroid, 13.4 x 12.4 (11-16 x 9-14) micrometers, with sporocysts ovoid, 9.2 x 6.3 (8-11 x 5-7) micrometers. This species was found in 27 of 45 (60%) U. Talpoides. Only 14 of 38 (36.8%) infected hosts (one D. pilirostris, 13 U. talpoides) were seen to be naturally infected with only one coccidian species when sampled.
