Two new species of the subfamily Picobiinae (Acari: Prostigmata: Syringophilidae) are described: Picobia ploceus sp. n. from Ploceus ocularis Smith (Passeriformes: Ploceidae) and Picobia lamprotornis sp. n. from Lamprotornis superbus (Rüppell) (Passeriformes: Sturnidae), both from Kenya. Additionally, new hosts are recorded: Turdoides jardineii (Smith) (Passeriformes: Leiothrichidae) from Kenya and Tanzania, T. rubiginosa (Rüppell) from Kenya, T. leucopygia (Rüppell) from Zambia and Namibia, for Picobia dziabaszewskii Glowska, Dragun-Damian et Dabert, 2012; Pycnonotus barbatus (Desfontaines) (Passeriformes: Pycnonotidae) from Kenya, for Picobia pycnonoti Glowska, Skoracki et Khourly, 2007; Dendropicos griseocephalus (Boddaert) (Piciformes: Picidae) from Tanzania and D. goertae (St. Müller) from Kenya, for Neopicobia freya Skoracki et Unsoeld, 2014; Dendropicos fuscescens (Vieillot) from Zambia and Campethera nubica (Boddaert) from Kenya, for Picobia dryobatis (Fritsch, 1958).
Ascaridoid nematodes referable to Brevimulticaecum heterotis (Petter, Vassiliadès et Marchand, 1979) Khalil, 1984 were recorded from the intestine of the African bonytongue, Heterotis niloticus (Cuvier) (Arapaimidae, Osteoglossiformes), from the Mare Simenti in the Niokolo Koba National Park, East Senegal and from Kosti, Sudan. Their examination using light microscopy and for the first time both environmental scanning electron microscopy and scanning electron microscopy revealed some previously unreported morphological features and made possible a detailed redescription of this species. The most important finding is the presence of dentigerous ridges on the inner edges of the lips, which confirms the attribution of this species to Multicaecum Baylis, 1923, where it was originally placed, and not to Brevimulticaecum Mozgovoy in Skryabin, Shikhobalova et Mozgovoy, 1951 where it had subsequently been transferred. A key to Brevimulticaecum and Multicaecum species is provided. Multicaecum heterotis is the first species of the genus to be sequenced. Partial sequences of the small ribosomal subunit (18S) and internal transcribed spacer 2 region (ITS2) of nuclear ribosomal DNA (rDNA) have been analysed and compared with other nematode species.
Nosorožci tuponosí (Ceratotherium simum) a Cottonovi (Ceratotherium cottoni) mají nejvyvinutější sociální systém ze všech druhů nosorožců, přesto toho o jejich sociálním chování a především komunikaci bylo donedávna známo jen málo. V článku jsou popisovány výsledky čtyř recentních studií, které se zabývaly sociálním chováním a vokální a olfaktorickou komunikací obou druhů v rezervacích v Jihoafrické republice i v zoologických zahradách., The Northern and Southern White Rhinos (Ceratotherium cottoni and C. simum) have the most developed social system among all the rhinoceros species. Until recently, little has been known about their communication and social behaviour. This paper presents the results of four recent studies involving research into the social behaviour and vocal and olfactory communication of these species both in the wildlife reserves in South Africa and in zoological gardens., and Ivana Cinková.
Fourteen species (twelve adult and two larval) of nematodes belonging to the Ascaridoidea, Camallanoidea, Cosmocercoidea, Habronematoidea, Oxyuroidea, Seuratoidea and Trichinelloidea were collected from fishes in the Sudan (River Nile and Atbara Dam Lake), whereas only four species (one adult and three larval) of the Ascaridoidea, Camallanoidea, Dioctophymatoidea and Trichinelloideafrom fishes in Ethiopia (Lake Tana). The Sudanese material also contained two previously unknown species, Cucullanus mormyri sp. n. from Mormyrus caschive Linnaeus (type host), Mormyrus sp. and Marcusenius cyprinoides (Linnaeus) (all Mormyridae), and Procamallanus (Spirocamallanus) pseudospiralis sp. n. from Synodontis schall (Bloch et Schneider) (type host), S. frontosus Vaillant and S. nigrita Valenciennes (all Mochokidae), which are described based on light and scanning electron microscopical studies. Cucullanus baylisi Campana-Rouget, 1961, a little-known parasite of Synodontis spp., is redescribed in detail. A key to Procamallanus (Spirocamallanus) spp. from African inland fishes is provided. Falcaustra guiersi Vassiliadès, 1973 is considered a junior synonym of F. hexapapillata (Khalil, 1962). The findings represent several new host and geographical records. Cucullanus baylisi Lakshmi, 2000 (= a homonym to C. baylisi Campana-Rouget, 1961) is re-named as C. dubius nom. n. and is considered a species inquirenda., František Moravec, Tomáš Scholz., and Obsahuje bibliografii
a1_Based on light and scanning electron microscopical studies, eight species (five adult and three larval) of nematodes belonging to the Ascaridida, Oxyurida and Enoplida were collected from fishes of the Okavango River, Botswana, namely Falcaustra similis Moravec et Van As, 2004, Atractidae gen. sp. (only female) (both Cosmocercoidea), Cucullanus sp. (only female) (Seuratoidea), Cithariniella longicaudata sp. n., Synodontisia annulata sp. n. (both Oxyuroidea), Contracaecum sp. third-stage larvae, third-stage larvae of Galeiceps sp. (both Ascaridoidea) and Eustrongylides sp. fourth-stage larvae (Dioctophymatoidea). The new species Citharinella longicaudata (type host Schilbe intermedius Rüppel) is mainly characterised by the shape and size of cephalic papillae and the spicule 108 µm long, and Synodontisia annulata (type host S. intermedius) by the shape of cephalic papillae, body length of gravid females (4.88-5.33 mm) and a short spicule (66 µm long). The female specimen of Cucullanus sp. from Tilapia sparmanni Smith markedly differs from congeners parasitising inland fishes in Africa by the elongate pseudobuccal capsule and by the excretory pore far posterior to the oesophago-intestinal junction; apparently, it belongs to an undescribed species. Galeiceps larvae parasitising fishes are described for the first time. Cithariniella gonzalezi Van Waerebeke, Chabaud, Bain et Georges, 1988 is considered a junior synonym of C. khalili Petter, Vassiliadès et Troncy, 1972, and the previous records of Cithariniella citharini Khalil, 1964 from Synodontis spp. in Egypt concern, in fact, Cithariniella khalili Petter, Vassiliadès et Troncy, 1972., a2_The specimens of Cithariniella reported by Koubková et al. (2010) from Paradistichodus dimidiatus (Pellegrin) in Senegal and misidentified as C. gonzalesi Van Waerebeke, Chabaud, Bain et Georges, 1988 are considered to represent a new species, C. koubkovae sp. n.; this is established by reference to the description and drawings provided by Koubková et al. (2010)., František Moravec, Liesl L. Van As., and Obsahuje bibliografii
One of four Hoplobatrachus occipitalis (Günther, 1859) frogs received from Niger, West Africa was heavily infected with Lankesterella blood and pre-erythrocytic stages. Infected blood and tissues from this frog were force-fed to the remaining three frogs. Two survived to necropsy on days 14 and 27 post-feeding and were found to be infected with gamogonic and oogonic stages, respectively. The source of infection is inconclusive, as a natural origin cannot be excluded. Microgamont, macrogamont, oocyst and sporozoite structure and fine structure are described and found to conform in general, but not in detail, to previous descriptions. Gamonts and oocysts occurred predominantly in the liver and spleen. Walled sporulating oocysts were situated within macrophage centres. Oocysts yielded a progeny of 32 sporozoites. Pre-erythrocytic sporozoites developed within expanded inclusions, within their host cell, from which they massively invaded the liver and spleen, and to a lesser extent the lungs and kidneys. Sporozoites occurred in a parasitophorous vacuole in the erythrocytes. Conspecificity with Lankesterella dicroglossi Paperna et Ogara, 1996 reported from the same host species in Kenya remains uncertain due to several structural and developmental differences.
The genus Liuella Wang et Bai, 1992 is transferred from Trombiculidae to Apoloniinae and a new species Liuella monosetosa sp. n. described from specimens taken in Morocco from the hosts Gerbillus sp. and Meriones libycus Lichtenstein. A new species of Straelensia Vercammen-Grandjean et Kolebinova, 1968, Straelensia variocula sp. n. is described from specimens taken in Morocco and Burkina Faso from the hosts Genetta thierryi Matschie, Gerbillus sp., M. libycus and Elephantulus rozeti (Duvernoy). A list of species, hosts and localities and a key to the species of the Apoloniinae of the world are presented.
Two new species of Cylicospirura Vevers, 1922 are described from carnivores from southern Africa. Cylicospirura crocutae Junker et Mutafchiev sp. n. from Crocuta crocuta (Erxleben) in Zimbabwe is distinguished from its congeners by combinations of characters, including the presence of four cephalic and four external labial papillae, while internal labial papillae were not distinct, the presence of groups of small accessory teeth between the six large tricuspid teeth, the fifth and the sixth pairs of the caudal papillae being equidistant from the cloaca, and a large ratio of length of the muscular oesophagus to that of the glandular oesophagus. Cylicospirura pardalis Junker et Mutafchiev sp. n. from Panthera pardus (Linnaeus) in the Republic of South Africa is characterized by having tricuspid teeth with large, claw-like, abaxial cusps, four cephalic and six internal labial papillae. Based on the number of caudal papillae and the position of the vulva, the subgenera Gastronodus Singh, 1934 and Skrjabinocercina Matschulsky, 1952 are re-elevated to generic rank. Amended diagnoses are proposed for the genera Cylicospirura, Gastronodus and Skrjabinocercina. Petrowospirura lyncis Matschulsky, 1952 is recognized as valid and, together with P. petrowi Sadykhov, 1957 and P. barusi Arya, 1979, is transferred to Cylicospirura as C. lyncis (Matschulsky, 1952) Junker et Mutafchiev comb. n., C. petrowi (Sadykhov, 1957) Junker et Mutafchiev comb. n. and C. barusi (Arya, 1979) Junker et Mutafchiev comb. n., respectively.
