“…The present SEM results for spine distribution (Figs. 9 & 10) are similar to those reported by Bakke (1976b) for Leucochloridium sp., but contrast with results earlier reported for L. paradoxum from West Germany (Heckert, 1889) and Poland (Pojmanska, 1967), where the whole body, as seen by light microscopy, is said to be covered by spines. The only differences found in microtopography between L. paradoxum and the Norwegian perturbatum forms of L. variae (Bakke, 1976a, b) were in point number and spine size (respectively lower and smaller in L.…”

In Pseudoplagioporus interruptus (Family Opecoelidae), folds on the tegument overlying the suckers may result from body flexure and movements of the oral sucker itself (Abdou et al 2001).…”

“…Domed aciliate papillae on the surface appear to be common for Brachylaimoida (Leucochloridium sp.) and Gorgoderioidea (Phyllodistomum conostomum) (Bakke 1976). However, the papillae of the oral sucker of Schistosoma mansoni were wart-like cuticular bosses (Miller et al 1972), and spherical surface elevations in Gorgoderina attenuata (Nadakavukaren and Nollen 1975).…”

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.

“…Each spine bears 3--25 points. According to Bakke (1976b) the absence of spines on the suckers in Leucochloridium sp indicates the necessity for smooth sealing against the host mucosa as in Fasciola hepatica (Bennett 1975a,b). In B. karuei the spines appear to help in attachment to the host tissue.…”
