The National Center for Biotechnology Information does not indicate that any phylogenetic analysis has been published on Raosentis that would confirm its position as a unique order in the family Quadrigyridae.

[5] R. dattai was found infesting the intestine of the Eutropiichthys vacha in the Gomti river in Lucknow.

Male has a small body small with hypodermic nuclei 4-5 pairs dorsally and 2-3 pairs ventrally, 2.68 x 0.7 Proboscis 0.24 x 0.18.· armed with 4 circles of hooks arranged in 6,6,8,8 per row.

[7] R. ivaniosi was found infesting the small intestine of the Flatmouth sea catfish (Arius platystomus) in Veli Lake, Puvar and Vellayani, Kerala.

thapari distinguished from R. podderi mainly on the number of hypodermic nuclei on dorsal and ventral trunk.

It was found infesting the small intestine of the striped dwarf catfish (Mystus vittatus) in river Godavari (Gorakhpur.

[10] Older measurements from Rai (1967) found the male with a Body size of 1.7-2.37 x 0.57-0.68.

Lemnisci equal, 0.55 x 0.075, hypodermic nuclei dorsally and ventrally 3 pairs.

[2] The life cycle of an acanthocephalan consists of three stages beginning when an infective acanthor (development of an egg) is released from the intestines of the definitive host and then ingested by an arthropod, the intermediate host.

This stage involves penetrating the wall of the mesenteron or the intestine of the intermediate host and growing.

The acanthor are passed in the feces of the definitive host and the cycle repeats.

Although paratenic hosts (hosts where parasites infest but do not undergo larval development or sexual reproduction) are found in the order Gyracanthocephala, none have been described for Raosentis species.
