Brooks, O'Grady & Glen (1985b) placed the seemingly aberrant and highly derived family Heronimidae at the base of their cladogram of the Digenea. In the absence of arguments for the composition and polarity of the putative homologous series on which their cladogram is based, it was found necessary to consider in detail almost all of their character series. In the course of my analysis I (1) argue that the oral sucker is singular to the Digenea, and that the oral sucker is not synapomorphic nor the ventral sucker symplesiomorphic for the Digenea, but that early digeneans lacked both suckers, (2) reiterate that the amphistomate condition is secondary and has arisen more than once, and that the embryology of the excretory system proves it to be secondary in all cases, (3) offer support for Cable's view that the cercarial stylet is not of single origin, and (4) restate the argument that paramphistomes, microscaphidiids, and gyliauchenids have not an oral sucker but a pharynx. Brooks, Bandoni, Macdonald & O'Grady (1989) stated that the bifurcate gut is unambiguously a synapomorph of the Digenea, on the basis of their cladistic demonstration that Rugogaster with a bifurcate gut is a sister group to the rest of the Aspidobothria, which in turn is a sister group to the Digenea. Testing this in a new cladogram of the Aspidobothria constructed from Brooks et al. 's (1989) 15 characters (corrected, especially those of the ventral sucker, for which a new phylogeny is advanced), supplemented by an additional 23 characters, reveals Rugogaster as the derived form it appeared to be and aspidogastrids, with a single caecum, as sister group to the rest of the Aspidobothria.A new analysis of the characters produced an increase in homoplasy from 18% to 37%, showed 97 out of 212 characters invalid as used, these two resulting in a decrease in resolution from 82% to 32%, and resulted in changes in polarity in 20 of the 65 putative homologous series listed by Brooks et al. (1985b).The Heronimidae cannot be at the base of their cladogram as it has not three but 13 apomorphs, which is more than have the next three groups, the paramphistomiforms, echinostomatiforms and haploporiforms.Comparison of the Heronimidae with the Bivesiculidae in the light of 48 defensible plesiomorphs shows that the Bivesiculidae, which have 39 of the 48 characters, are more plesiomorphic than the Heronimidae, which have only 23.In conclusion, what remains of the data-base is insufficient to support their cladogram and classification. Better data from the flukes themselves are necessary for a sound cladistic analysis. 82 J.C. Pearson

“…Light microscopy-based studies on the hemiuroid worm, genus Genarchopsis, usually parasitic in the oesophagus and stomach of fishes have a rich history from India (Gupta 1951;Kakaji 1969;Rai 1971;Pandey 1973;Madhavi 1978;Varma and Sahay 1983;Bhadauria and Dandotia 1984;Pardeshi and Hiware 2012), adjoining countries (Bashirullah and Elahi 1972;Rehana and Bilqees 1980;Khan 1991;Shaikh et al 2011), and elsewhere (Ozaki 1925;Shimazu 1995;Urabe 2001;Gibson et al 2002;Urabe et al 2012) focusing on taxonomic descriptions and life cycle patterns. The genus Allogenarchopsis, with A. problematica from Japan as the type species (Urabe and Shimazu 2013), a new genus of endoparasitic digenetic worm is an offshoot of Genarchopsis, G. goppo from Mogurnda obscura (a synonym of Odontobutis obscura) in Japan being the type species (Ozaki 1925).…”

The stomach of the freshwater snakehead murrel, Channa striata (n = 250) collected from fresh water habitats of Bareilly, Uttar Pradesh, India revealed Allogenarchopsis, a trematode parasite (Plagiorchiida: Derogenidae). An illustrated account of light (Olympus BX-53 with Cellsens software imaging system) and scanning electron microscopy (SEM) (Neo JCM-6000) of Allogenarchopsis bareilliensis n. sp. (prevalence 37 %, intensity 1-4 par/host) is provided. Light microscopy based studies warranting creation of a new species are the robust shape of the body with broad mid-body, blunt anterior and tapering posterior end, large ventral sucker, ratio of oral sucker: ventral sucker 1:3.5, pharynx broader than long, egg size small with relatively short egg filament, excretory vesicle U-shaped bifurcating at posterior end and terminating above intestinal shoulders. Key characteristics of the tegumental microtopography by SEM are (1) an aspinous tegument with a variety of papillae of different shapes (button-like, dome-shaped) distributed randomly on the dorsal and ventral surface (2) oral sucker and oral cavity muscular with fringed margins and morphologically different oral papillae (3) lip of ventral sucker papillated including two unequally spaced rows of papillae with sensory receptacles interspersed in between, (4) unique differentially texturized cytoplasmic processes on the ventral sucker and (5) body folds grooved, gradually becoming narrower towards posterior end. This is the first record and study on Allogenarchopsis from Channa of Rohilkhand, India using electron optics. We recommend that the newly recognized morphological features as revealed by light microscopy and SEM be utilized as taxonomic tools in future for the identification of the species.

“…It showed positive correlations with temperature, FCO 2 and conductivity and negative correlation with pH. Ecological factors have been held widely responsible for the occurrence of adult digenetic trematodes quoted from Chubb (1979) and Madhavi (1978). Aquatic organisms are affected by pH because most of their metabolic activities are pH dependent (Wang et al, 2002).…”

Infection with trematode parasites can lead to severe change in nutrient content and may result in host mortalities and character of a water body may influence the parasitic fauna. Hence a study was carried out from 2010 to 2011 to find out a correlation of water's physic-chemical characteristics and trematode parasites of Channa punctata (Bloch) in Awangsoi Lake, Manipur, India. During the present investigation three species of trematodes were recorded. In the present study there were concurrent infections by two or more parasite species. The percentage of infection was positively correlated with temperature, pH, DO and conductivity in Awangsoi Lake. There was a significant positive correlation (r = 0.652; p<0.05) with FCO 2 and a negative correlation with alkalinity. Seasonal variation in the occurrence of these parasites may be attributed to ecological conditions, particularly distribution of intermediate hosts and also the age of the host and the life cycle of the parasite species.
