Brachylepis gen. n.--a new genus of cestodes (Cyclophyllidea: Hymenolepididae) from shrews in Siberia and the Far East

A new genus Brachylepis gen. n. hymenolepididean cestodes associated with common shrews (Sorex) in Siberia and Russian Far East is created. These genus includes three species removed from the genus Mathevolepis: Brachylepis morosovi (Karpenko, 1994) comb. n. (type species), B. sorextscherskii (Morosov, 1957) comb. n. and B. triovaria Karpenko, 1990) comb. n. The new genus is characterized by the gradual strobila with a little number of segments, unarmed scolex with apical glandular organ, by lack of internal seminal vesicle and differential seminal receptacle, by form of uterus as horse shoe in young worms and buble-like in mature worms. A tendency of inverse proportional dependence between the number of uterus segments in the strobila and the number of hexacanths in the uterus has been noticed. The table of differential characters for the species of the genus Brachylepis is proposed.     

Mathevolepis junlanae sp. n. (Cyclophyllidea: Hymenolepididae: Ditestolepidini), a new cestode species from shrews of Far East

Mathevolepis junlanae sp. n. from shrews (Sorex spp.) of Far East is described given. The new species occupies an intermediate position between the Palaearctic species M. petrotschenkoi Spassky, 1948 (total number of proglottids--4) and M. skrjabini (Sadovskaya, 1965) (10-12 segments in a series) by the number of synchronously developing proglottids (2-4). The new species differs from M. larbi Karpenko, 1982 by the structure and measurements of copulative apparatus in proglottids. In M. larbi, vagina S-shaped, vagina length 0.147-0.154 mm, cirrus length 0.146-0.149 mm, and cirrus bursa reaching aporal excretory vessels. M. junlanae sp. n. has cirrus bursa slightly crossing center line of sexually mature proglottids, cirrus about half as long (0.084-0.092 mm), and smaller sac-shaped vagina (0.075-0.10 mm). The new species differs from the Nearctic representative M. macyi (Locker and Rausch, 1952) by lesser measurements of cirrus bursa (0.12-0.14 mm versus 0.4 mm) and a fewer number of proglottids in series (2-4 versus 5-7).

A new species of cestode, Vampirolepis muraiae n. sp. (Cyclophyllidea: Hymenolepididae), from a Chinese bat

Vampirolepis muraiae n. sp. (Cestoda: Cyclophyllidea: Hymenolepididae) is described on the basis of a single specimen from a mouse-eared bat, Myotis sp., from Yunnan Province, China. It is distinguished from its congeners on the basis of the size and shape of the rostellar hooks, which have a blade shorter than the guard, the tubular structure of the initial stage of the developing uterus and eggs with a thick outer coat.     

Microsomacanthus polystictae sp. n. and other cestodes of the family Hymenolepididae (Cyclophyllidea) from Steller's eider Polysticta stelleri from the Chaun lowlands (northwestern Chukotka)

8 species of cestodes belonging to the family Hymenolepididae were recorded from Polysticta stelleri (Pall.) in the Chaun lowland. A new species of hymenolepidids, Microsomacanthus polystictae sp. n., differing from close (by the length of proboscis hooks) species of the genus in the structure and size of the copulatory organ is described. Brief diagnosis of the new species: cestodes small, specimens ending with hermaphrodite proglottids 2.44 to 2.91 mm long. Proboscis hooks 0.038 to 0.042 mm long, blade 0.011 to 0.012 mm long. Strobila of maximum length with 84 proglottids. In young male proglottids the aporal testis half as large as poral and median ones, in well-developed proglottids testes 0.020 to 0.026 X 0.023 to 0.032 mm. Bursa of cirrus 0.150 to 0.190 X 0.020 to 0.028 mm. Cirrus 0.107 mm long, basis 0.008 to 0.011 mm wide, median part 0.012 to 0.014 mm wide, apical part 0.004 mm wide. Cirrus armed with spines 0.003 to 0.004 mm long. Ovary bilobate, yolk gland compact. Spermatheca small, situated medially, in front of poral ovary lobe. Copulative part of vagina sacciform, 0.086 to 0.118 mm long, 0.023 to 0.037 mm maximum width. Distally and proximally vagina with muscular sphincters. Uterus sacciform, with 35 to 40 embryos. There were no mature "eggs" in the material.     

Description of a new species of Proteocephalus pronini sp.n. (Cestoda: proteocephalidae)--a parasite of grayling from lake Hovsgol

A new cestode species, Proteocephalus pronini sp. n., is described from the Lake Hovsgol Grayling Thymallus arcticus nigrescens (Mongolia, Hovsgol Lake). The new species differs from P. thymalli from the Baikal Lake by the length of strobile, number of proglottids, form of mature proglottids, and number of diverticles of uterus.     

Lanfrediella amphicirrus gen. nov. sp. nov. Nematotaeniidae (Cestoda: Cyclophyllidea), a tapeworm parasite of Rhinella marina (Linnaeus, 1758) (Amphibia: Bufonidae)

The family Nematotaeniidae, tapeworms commonly found in the small intestines of amphibians and reptiles, includes 27 recognised species distributed among four genera: Bitegmen Jones, Cylindrotaenia Jewell, Distoichometra Dickey and Nematotaenia Lühe. The taxonomy of these cestodes is poorly defined, due in part to the difficulties of observing many anatomical traits. This study presents and describes a new genus and species of nematotaeniid parasite found in cane toads (Rhinella marina) from eastern Brazilian Amazonia. The cestodes were collected during the necropsy of 20 hosts captured in the urban area of Belém, Pará. The specimens were fixed and processed for light microscopy, scanning electron microscopy (SEM) and three-dimensional (3D) reconstruction. Samples were also collected for molecular analyses. The specimens presented a cylindrical body, two testes and paruterine organs. However, they could not be allocated to any of the four existing nematotaeniid genera due to the presence of two each of dorsal compact medullary testes, cirri, cirrus pouches, genital pores, ovaries and vitelline glands per mature segment. Lanfrediella amphicirrus gen. nov. sp. nov. is the first nematotaeniid studied using Historesin analysis, SEM and 3D reconstruction, and it is the second taxon for which molecular data have been deposited in GenBank.     

Ultrastructure of the reticulate uterus and specific features of matrotrophy in three species of higher cestodes (Cestoda,Cyclophyllidea)

The ultrastructure of the reticular uterus has been analyzed in pregravid and gravid proglottids of cyclophillid cestodes dwelling in water (Alcataenia dominicana and A. larina) and in terrestrial hosts (Arostrilepis tenuicirrosa). Cells of the medullary parenchyma surrounding the uterus are filled with lipid inclusions in all species investigated. The hypertrophic development of small excretory ducts that surround the uterus, contact the uterine epithelium, and penetrate the diverticula is characteristic of Alcataenia dominicana and Arostrilepis tenuicirrosa. A comparative analysis of the results and the data available for other cestode species allow for the assumption that the reticulate structure of the uterus, lipid accumulation, and contacts between the uterine epithelium and the excretory ducts are morphological and functional adaptations that enable matrotrophy and the attainment of maximal fecundity by cyclophillid cestodes.     

Life-cycles of cestodes of the genus Branchiopodataenia Bondarenko & Kontrimavichus, 2004 (Cestoda: Hymenolepididae) from gulls in Chukotka

Data are presented on the life-cycles and the postembryonal development of four species of Branchiopodataenia Bondarenko & Kontrimavichus, 2004, B. anaticapicirra Bondarenko & Kontrimavichus, 2004, B. arctowskii (Jarecka & Ostas, 1984), B. haldemani (Schiller, 1951) and B. pacifica (Spassky & Jurpalova, 1968), which are specific parasites of gulls. The investigation was carried out in Chukotka (Chaun Bay) between 1971 and 1981 under natural and experimental conditions. Branchiopod crustaceans were exclusive natural and experimental intermediate hosts of all of the species studied; this fact provided additional evidence for the erection of Branchiopodataenia. The metacestodes exhibit a pattern of postembryonal development and a typical larval form, termed a 'cercocyst', which is a modification of a cysticercoid. This modification of the metacestode does not occur in species of Wardium Mayhew, 1925, the genus with which species of Branchiopodataenia had previously been affiliated.     

Sobolevicanthus transvaalensis n.sp. (Cestoda: Hymenolepididae) from the Cape Teal (Anas capensis Gmelin, 1789)

Summary Sobolevicanthus transvaalensis n.sp. is described from the Cape Teal, Anas capensis Gmelin, 1789, collected in the Republic of South Africa. The new species possesses 8 skrjabinoid hooks 78–88 m long (mean 85 m) and a short claviform cirrus-sac 79–143 m long and resembles S. javanensis (Davis, 1945) and S. terraereginae (Johnston, 1913). It can be distinguished from S. javanensis by its shorter cirrus-sac and smaller cirrus diameter, and by differences in the morphology of the accessory sac and vagina and in their position relative to the cirrus-sac. It can be separated from S. terraereginae on the basis of cirrus length and diameter. The basal diameter of the cirrus in S. terraereginae is three times that in S. transvaalensis. ac]19830414     

Helminths of rodents and marsupials from Papua New Guinea,with the description of two new species,Echinostoma echymiperae n. sp. (Digenea: Echinostomatidae) and Vampirolepis peroryctis n. sp. (Cestoda: Hymenolepididae)

The following rodents and marsupials from the Western Highlands of Papua New Guinea have been examined for helminths: Anisomys imitator, Melomys spp., Pogonomelomys ruemmleri, Rattus spp., Echymipera kalubu and Peroryctes raffrayanus. Two new species and a number of new host records are reported. Echinostoma echymiperae n. sp., a digenean from the intestine of Echymipera kalubu, is characterised by the number of collar spines, the body armature and the shape and position of the gonads. Vampirolepis peroryctis n. sp., a cestode from the intestine of Peroryctes raffrayanus, is characterised by the length of the rostellar hooks, the shape of the ovary, the arrangement of the testes in a triangle and the extent of the cirrus-sac. Hymenolepis aklei, H. bradleyi, H. antechini, H. bettongiae, H. cercarteti, H. isoodontis and H. potoroi are transferred to Vampirolepis as new combinations. E. kalubu is a new host for Linstowia semoni and Pogonomelomys ruemmleri is a new host for Hymenolepis diminuta. V. peroryctis is the first platyhelminth to be reported from Peroryctes raffrayanus and Raillietina (Raillietina) sp. the second to be reported from the genus Melomys.     

Wardium canarisi n. sp. (Cestoda: Hymenolepididae) parasite de Arenaria melanocephala (Aves: Charadrii) d'Alaska

The authors describe and illustrate Wardium canarisi n. sp. (Cestoda: Hymenolepididae), an intestinal parasite of Arenaria melanocephala (Aves: Charadrii) from Alaska, characterised by a strobila 20–40 mm long, 10 aploparaksoid hooks 19–21 m long, a short cylindrical cirrus (40 m) covered with very minute spines (0.2 m), and a short (8–18 m) and extremely narrow (1 m) copulatory vagina. These characters have no equivalent, even approximate, among the 27 species of Wardium parasitic in the Charadrii which are reviewed. The genus Debrosia Spassky, 1987 appears to be justified.     

Bauhinia sirindhorniae sp. nov. (LeguminosaCaesalpinioideae) a remarkable new species from Thailand

Bauhinia sirindhorniae sp. nov., from Nong Khai Province, Thailand is described and illustrated. The pollen morphology has been studied.     

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.     

A new species of blastobotrys: Blastobotrys navarrensis sp. nov. (Hyphomycetes)

A new species of Blastobotrys Klopotek (1, 2, 4, 5) has been recovered from white pepper. It appears to be sufficiently distinct from B. nivea v. Klopotek. (5), B. proliferas Marvanová, and B. aristata Marvanová (2), to be described as a new species under the name of Blastobotrys navarrensis. Both morphological as well as physiological characteristics were taken in account to differentiate the new species from Blastobotrys species known up to date.     

Polysiphonia freshwateri sp. nov. and Polysiphonia koreana sp. nov.: two new species of Polysiphonia (Rhodomelaceae,Rhodophyta) from Korea

Polysiphonia sensu lato comprises approximately 200 species, which are currently assigned to several different genera. To date, one of these genera, namely, Polysiphonia, has been reported to have 17 species. Here, we describe for the first time P. freshwateri sp. nov. and P. koreana sp. nov. from Uljin and Ulleung Island, Korea, based on morphological and molecular evidence. Polysiphonia freshwateri sp. nov. and P. koreana sp. nov. are characterized by having the typical Polysiphonia features. Polysiphonia freshwateri sp. nov. is further characterized by having abundant trichoblasts, conspicuous scar cells, and tetrasporangia arranged in spiral series. Polysiphonia koreana sp. nov. is further characterized by having very scarce scar cells placed between two pericentral cells, from which cicatrigenous branches arise. The results of our rbcL sequence analyses support the taxonomic placement of P. freshwateri sp. nov. and P. koreana sp. nov. within Polysiphonia.
