Haemolymph was collected from the crabs and subjected to the light microscopy, transmission electron microscopy, and flow cytometric analysis for the cytomorphological characterization and classification. Total and differential haemocyte counts were also carried out. On the basis of various cytomorphological features, haemocytes of V. litterata were classified into hyalinocytes, small granule haemocytes and large granule haemocytes. Hyalinocytes are round, oval, irregular, spindle or ellipsoid shaped cells with low to high nucleo-cytoplasmic ratio and contained a number of cytoplasmic organelles and a few minute-sized granules in the cytoplasm. Small granule haemocytes are large sized ovoid or ellipsoid shaped cells with a relatively high nucleo-cytoplasmic ratio and possessed numerous small sized granules. Large granule haemocytes are comparatively large-size, circular or ovoid shaped haemocytes with a high nucleo-cytoplasmic ratio and contained numerous large round refractile granules and a few small granules. Total haemocyte count of V. litterata is noted as 1.021 x10 6 to 3.108 x10 6 with a mean value of 2.145 ± 0.84 x 10 6 cells ml –1 . The relative percentages of hyalinocytes, small granule haemocytes and large granule haemocytes are accounted as 13.93, 55.24 and 30.83% respectively in the haemolymph. Outcome of this study might provide valuable information regarding the haemocyte profile of V. litterata that would be helpful to carry out further studies on haemocyte structural types to know about their specific functions and immune mechanisms.","PeriodicalId":37977,"journal":{"name":"Invertebrate Zoology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85098571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In India, the occurrence of temnocephalids was recorded and studied from preserved specimens. Regarding the morphology of the specimens, vague descriptions were given. Since then, no following studies were found. This study provides a new insight regarding the specimens found on a freshwater crab, Maydelliathelphusa lugubris (Wood-Mason, 1871). The specimens are identified as Temnosewellia semperi (Weber, 1890) based on the presence of brown pigment, five tentacles, posterior adhesive disc, five syncytial plates: tentacular, postentacular, body, peduncular and adhesive plates, the excretory pore lying on the dorsal side of the body plate and the absence of papillae on the dorsal surface or tentacular surface. The most important diagnostic feature is the structure of the cirrus which is the main taxonomic character to identify the species. Temnosewellia semperi has a nearly straight cirrus with the distal part slightly dilated as observed in this species.","PeriodicalId":37977,"journal":{"name":"Invertebrate Zoology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80860765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
