AbstractTwo species of parasitic nematodes, Heliconema ahiri Karve, 1941 (Physalopteridae) and Procamallanus (Spirocamallanus) anguillae Moravec et al., 2006 (Camallanidae), were recorded from the Indonesian shortfin eel Anguilla bicolor bicolor Mc-Clelland in the Chalakkudi River and Veli Lake, respectively, both Kerala, India. The former species (H. ahiri), rediscovered from eels in India after 82 years from its original description, has been redescribed and revalidated based on its specific feature (presence of groups of minute denticles in the mouth) distinguishing it from other congeners; its finding in A. b. bicolor represents a new host record. The latter species (P. anguillae) has been recorded in India for the first time. SEM examination of its first-stage larvae from uterus has shown that P. anguillae is another species of Procamallanus whose larvae possess a crown of digit-like processes at the tail tip.

Abstract One new and one known species of parasitic nematodes are reported from Thailand for the first time: Falcaustra kaverii (Karve et Naik,1951) (Kathlaniidae) from the intestine of the freshwater fish Poropuntius deauratus (Valenciennes) (Cyprinidae) (new host record) and Ascarophis scatophagi sp. nov. (Cystidicolidae) from the intestine of the marine fish Scatophagus argus (Linnaeus) (Scatophagidae). The morphology of both these species was studied with the use of light (LM) and scanning electron microscopy (SEM) (the latter method used for F. kaverii for the first time). The new species (A. scatophagi) is mainly characterized by nonfilamented, markedly elongate-oval eggs (size 42–45 × 18 μm), spicules 555–642 μm and 105–150 μm long, the muscular/glandular oesophagus length ratio (1:13–34), bifurcate deirids, the length of the female tail (159–249 μm) and cephalic structures typical of the nominotypical subgenus Ascarophis. Representatives of Falcaustra Lane, 1915 and Ascarophis van Beneden, 1871 were not previously reported from fishes in Thai waters.

AbstractThe nematode Rhabdochona cotti Gustafson, 1949 is redescribed from specimens collected from the intestine of the blue ridge sculpin Cottus caeruleomentum (a new host record), a recently described fish species, from Little Fishing Creek in Maryland, USA. The measurements of these specimens, collected in November 2005, are generally smaller than those reported in the original description of R. cotti, this being probably associated with the nematode’s seasonal maturation cycle or the different host species. As revealed by SEM, the deirids of R. cotti are simple (not bifurcate), in which this species differs from almost all North American congeners. Of these, simple deirids, filamented eggs and a rounded tail tip in females occur only in Rhabdochona longleyi, but it distinctly differs from R. cotti in the smaller number of anterior prostomal teeth (6 vs. 14). Rhabdochona rotundicaudatum is considered a junior synonym of Rhabdochona cascadilla; numerous specimens of the latter were collected from Semotilus atromaculatus, Luxilus cornutus and Notropis rubellus from the type locality (Eramosa River, Ontario, Canada) (unpublished). Rhabdochona paxmani and Rhabdochona salmonis are synonymized with Rhabdochona kisutchi, whereas Rhabdochona californiensis is considered a junior synonym of R. cascadilla. The need of a taxonomic revision of North American species of Rhabdochona is stressed.

Plasmodium (Sauramoeba) diploglossi Aragão & Neiva, 1909, has been rediscovered in the skink Mabuya mabouya (Scincidae). This appears to be the first time that this malaria parasite has been re-encountered since its original description in the lizard Diploglossus fasciatus (Anguidae). Six out of 20 skinks were infected, all from the Utinga Forest, Belém, Pará, north Brazil.P. (Sauramoeba) tropiduri Aragao & Neiva, 1909, is redescribed in the samelizard, Mabuya mabouya, representing a new host record. Many of the infections were concomitant with P. diploglossi. Exo-erythrocytic schizonts were encountered in blood and tissue smears but it remains uncertain to which parasite they belong.P. (Sauramoeba) cnemidophori Carini, 1941, has been found in the teiid lizard Ameiva ameiva, a new host record. Exo-erythrocytic schizonts were abundant in lymphocytes and thrombocytes of the peripheral blood.The cost of the colour plate was defrayed by the Wellcome Parasitology Unit, Institute Evandro Chagas, Fundacao Servico Especial de Saúde Pública, Belem, Pará, Brazil.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

Morphological Diagnosis

ABSTRACT During a survey conducted in the Lajeado Reservoir of the Tocantins River, in the state of Tocantins, Brazil, dactylogyrids were recovered from the gills of Pimelodina flavipinnis. Initial morphological analysis showed these dactylogyrids shared aspects of character with species of Demidospermus, with affinity to Demidospermus pinirampi, despite exhibiting differences with the original description by Kritsky et al. (1987) regarding the vagina, the base of the male copulatory organ and the shape and length of the bars. The analysis of the holotypes of D. pinirampi and its most morphologically close species, Demidospermus luckyi, revealed that these dactylogyrids were indeed D. pinirampi. This study therefore reports a new host and locality of occurrence, and reviews some measurements of the original description, supplementing and enhancing the morphological diagnosis of D. pinirampi.

Steringovermes notacanthi, a new genus and species of fellodistomine digenean, is described from the deep-sea spiny eel Notacanthus bonaparte from below 1,000m depth in the north eastern Atlantic. It differs from other related genera in the unique combination of a V-shaped excretory vesicle, multilobate, mainly post-testicular ovary and extensive vitelline fields extending into both the foreand hindbody. In addition, the fellodistomine Olssonium turneri Bray & Gibson, 1980 is reported for the first time from a fish not of the genus Alepocephalus, namely the alepocephalid Narcetes stomias.

AbstractTwo species of Kalicephalus Molin, 1861 were collected from the intestine of Varanus salvator (Laurenti, 1768) from Guangdong Wildlife Rescue Centre, Guangzhou, Guangdong Province, China. Kalicephalus (Kalicephalus) guangdongensis sp. nov. is similar to K. (K.) schadi Ogden, 1966 and K. (K.) schadi fotedari Kalia et Nayital, 1989 in having extremely long spicules, but differs from the latter in the relative length of spicules (spicules longer than the total body length instead of spicules almost three quarters of the total body length). Kalicephalus (Kalicephalus) schadi fotedari Kalia et Nayital, 1989 is reported for the first time in China, and Varanus salvator is a new host record.

Haemosporidians are intracellular protozoan parasites found inside the blood cells and tissues of avian hosts; they are almost worldwide distributed and occur in a variety of avian species, including see-see partridge birds. Blood samples were collected from 63 see-see partridges during a period extended from 19th November 2018 to 15th March of 2019 in the Garmian area/Iraqi Kurdistan region to detect and investigate the infection rates of haemosporidian parasites by microscopic examination using Giemsa stained smears. The results of the study showed that out of the total samples numbers 63 only 43 were found infected with haemoprotozoan parasites composing the overall infection rate of 68,25%, from 32 birds which were infected with Plasmodium spp. at a rate 50,79%, and 8 birds were infected with Haemoproteus spp. at a rate of 12,69%., the results also revealed that the rates of infection with these protozoan parasites vary substantially among the sampled locations. The present study showed that two haemosporidian genera (Haemoproteus spp. and Plasmodium spp.) were detected in see-see partridges in Kurdistan region-Iraq for the first time, and this type of bird is considered as a new host record for these haemoprotozoa in this area.
