Zwei Trematoden-Arten,Odeningotrema bivesicularis n.g., n.sp. und Novetrema nycticebi n.g., n.sp. (Odeningotrematinae n. Subfam., Lecithodendriidae), aus dem Darm von Nycticebus coucang in Malaya

Summary Two trematodes from the intestine of the Slow Loris, Nycticebus coucang, in Malaya, are described: Odeningotrema bivesicularis n. g, n.sp., and Novetrema nycticebi n.g., n.sp. (Fam. Lecithodendriidae Odhner, 1911, Odeningotrematinae n. subfam.). Both species are less than 1 mm long. They differ from other species of the family Lecithodendriidae in the presence of a transverse cirrus sac at the level of the anterior margin of the acetabulum, a genital pore between the acetabulum and the side of the body at the level of the anterior margin of the acetabulum, and vitellaria which fill the posterior part and the sides of the body, beginning at the level of the pharynx.

Dionisia bunoi n. g. n. sp., Haemoproteidae parasite of the microchiropteran bat Hipposideros cyclops in Gabon (author's transl)

Dionisia bunoi ng. g., n. sp. is characterized by:--a) sexual dimorphism of gametocytes, macrogametocyte of the falciparum type, microgametocyte of the type malariae:--b) schizonts developing in the lumen of liver blood vessels inside a greatly hypertrophied host cell; their size remains moderate and their cytoplasm is not intensely basophilic as is usually in the young stages of Haemosporidia of Mammals. The genus has morphological characters in common with each of the 4 other genera of Haemoproteidae of Mammals. The phyletic hypothesis concerning the morphology of gametocytes and schizonts suggests that Bioccala and Dionisia are primitive.     

Maseria vespertilionis n.g., n.sp. (Dorylaimina : Muspiceidae), a nematode from nearctic bats (Vespertilionidae)

Maseria vespertilionis n. g., n. sp. (Dorylaimina : Muspiceidae) is described from nearctic bats (Vespertilionidae). In addition to the type host, Eptesicus fuscus (P. de Beauvois), in Oregon, M. vespertilionis was recorded from Myotis volans (Allen) in Oregon, and from M. lucifugus (Le Conte) in Oregon and Alaska. The nematode was found only in subcutaneous tissues near the plantar surface of the rear feet of the host. The genus Maseria is distinguished from other genera in Muspiceidae by various morphological characteristics, among which the presence of a Demanian system is important. The lesions produced in the feet of the host are described, and other biological characteristics of the nematode are discussed.     

A new myxosporidian,Rudicapsula esomi n.gen. n.sp., from the fresh-water fish,Esomus sp.

A new myxosporidian parasite is reported from the fresh-water fish,Esomus sp. (fam. Cyprinidae). It is characterised by the presence of one normal polar capsule with enclosed polar filament and a second rudimentary polar capsule. It has an iodinophilous vacuole in the sporoplasm. Since it does not fit the genusMyxobolus, which has two polar capsules and an iodinophilous vacuole, nor the genusThelohanellus, which has one polar capsule and an iodinophilous vacuole, a new genus and species is established to accommodate the form and the nameRudicapsula esomi n.gen. n.sp. is suggested.

Sphaerospora renicola n.sp., a myxosporean from carp kidney,and its pathogenicity

Sphaerospora renicola n.sp. is a common parasite of carp in Czechoslovakia. Its life cycle involves intracellular stages in the epithelial cells of renal tubuli and trophozoite stages proliferating in the tubular lumen, transforming ultimately into pansporoblasts, each having one pansporoblast nucleus and producing two spores. The spores are almost globular with an average size of 7.3×7.2 , with polar capsules of equal size, and may have two slightly protruding tubercles on their shell valves. Differential diagnosis from otherSphaerospora species infecting carp, as well as fromMitraspora cyprini Fujita, is made. Intracellular stages ofS. renicola cause swelling and hyperplasia of the epithelium in renal tubuli followed by dystrophic changes. Accumulation of developmental stages in the tubular lumen provokes pronounced regressive changes of the epithelium, which may be followed by necrosis.     

Ascaridia platyceri n.sp., a new species of nematode from parrots

A new species of bird parasitic nematode, Ascaridia platyceri n. sp., is described from the small intestine of Platycerus eximius and 8 further species of Psittacidae maintained in Zoological Gardens and private holdings in the GDR. The new species differs from the 3 species of Ascaridia hitherto known from parrots mainly in the shape of the anterior border of the lips as well as in the number and position of the caudal papillae in the male.     

Mansonella (E.) rotundicapita sp.n. and Mansonella (E.) longicapita sp.n. (Filarioidea : Onchocercidae) from Venezuelan capybaras, Hydrochoerus hydrochaeris

Mansonella (E.) longicapita sp. n. and Mansonella (E.) rotundicapita sp. n., two filarial nematodes from the dermis of Venezuelan capybaras, are described. The two species can be distinguished on the size of the spicules (M. longicapita 327 and 139 micron, ratio of 2.3 : 1 ; M. rotundicapita 405 and 120 micron, ratio of 3.4 : 1), the degree of lateral elongation of the cephalic shield and in the size and configuration of the microfilaria. The microfilaria of M. rotundicapita is large (280 micron long), and in specimens fixed in 2% formalin, the posterior end of the body is bent in a shepherd's crook, while the microfilaria of M. longicapita is short (195 micron long) and when similarly fixed, assumes a gently curved attitude. Within the subgenus M. (Esslingeria), the species M. longicapita and M. rotundicapita are intermediate in size. Morphologically they resemble M. streptocerca and M. rodhaini most closely, but can be distinguished on size, spicule morphology, and microfilarial morphology.     

Eine neue Gregarine,Fusiona geusi,n. sp., n. gen., n. fam., n. superfam., aus der südamerikanischen Schabe Pycnoscelus surinamensis L. 1758

Zusammenfassung In der vorliegenden Arbeit erfolgt die Beschreibung einer neuen Gregarinenart, Fusiona geusi n. sp., n. gen., n. fam., n. superfam. Gleichzeitig wird eine neue Gattung Fusiona n. gen., eine neue Familie Fusionidae n. fam. und eine neue Überfamilie Fusionoidea n. superfam. errichtet.Die neue Überfamilie Fusionoidea n. superfam. gehört zur Unterordnung Cephalina Delage et Herouard. Fusiona geusi n. sp. lebt im Darm und in den Darmanhängen der südamerikanischen Schabe Pycnoscelus surinamensis L. Die Trophozoiten haben einen eierförmigen Protomeriten und einen in einer Spitze auslaufenden Deutomeriten. Epimeritrudimente sind meist vorhanden.Der Protomerit der Sporonten ist rundlich. Das Hinterende der Sporonten ist gerundet.Die Gamonten sind zu zweien assoziiert. Die geschlechtlichen Vorgänge werden von einer Plasmafusion eingeleitet. Dabei wird das gesamte Entocyt samt dem Kern aus dem Satelliten in den Primiten transportiert. Die Gameten sind anisogam. Cysten wurden nicht beobachtet. Desgleichen ist nichts über die Entleerung der Sporen bekannt.

Summary A new gregarine, Fusiona geusi n. sp., n. gen., n. fam., n. superfam., is described. Also a new genus, Fusiona n. gen., a new family Fusionidae n. fam., and a new superfamily Fusionoidea n. superfam. was established.The new superfamily Fusionoidea n. superfam. belongs to the suborder Cephalina Delage et Herouard. Fusiona geusi n. sp. lives in the intestine and in the coeca of the southamerican cockroach Pycnoscelus surinamensis L.The trophozoites have an ovoid protomerit and a deutomerit ending in a point. The protomerit of the sporonts is rounded, also the distal end of the deutomerit.Gamonts are in associations of two. The sexual processes are starting with a fusion of the entocyt. Nucleus and entocyt of satellit are transported into the primit. Then follows the growing of gamets. They are anisogamets. Cysts and spores are unknown.
