Taxonomic study of two new species of the genus Mogheia (Lopez Neyera, 1994) from Skyes

-Two new species of the genus Mogheia , Lopez-Neyra in 1994 i.e., Mogheia yasini n.sp . and Mogheia shahadensis n.sp. were collected from Turdoides malcomi (Skyes) from different part of Maharashtra State India. The present parasites are differ from all the known species of the genus Mogheia , Lopez-Neyra,1994 in having length of worm, number and shape of testes, shape of cirrus pouch, shape of ovary, position of vagina and structure of vitellaria


Introduction
The genus Mogheia was erected by Lopez-Neyra in 1994.Moghe, 1933 synonimyzed it is a Baria with the type species M. orbiuterina from the intestine and gizzard of Turdoides somervillei in India.Since then eight species have been reported till to date under this genus.The genus Mogheia is the sole representative of the family Thysanosomidae from birds.The present communication deals with the description of a new species under the same genus viz.Mogheia yasini n.sp.and Mogheia shahadensis n.sp.collected from Turdoides malcomi (skyes), at Shahada M.S. India.

Material and Methods
The segmented cestode were collected intestine of from Turdoides malcolmi (skyes), preserved in hot 4% formalin, stained with Harris haematoxylin and Borax carmine, passed through various alcoholic grades, cleared in xylene, mounted in D.P.X. and drawings are made with the aid of Camera Lucida.All measurements are given in millimeters.

Discussion
The genus Mogheia was erected by Lopez-Neyra in 1944, as a type species Mogheia orbiuterina (Moghe, 1933) from the intestine of Turdoides somervillei in india.Later on the following eight species are added to this genus.There after no species is added to this genus.The present communication deals with the description of the new species, under the same genus i.e.Mogheia yasini n.sp.from Turdoides malcolmi at Shahada, M.S., India.1.After going through the literature, the worms under discussion, in having testes 10 in number comes under to M. orbiuterina Moghe,1933 and M. copsychi Gupta and Sinha,1984.2. In the present cestode, the testes are 10 in number and situated in the antiporal side, differ from M.orbiuterna, which is having testes 9 in number but situated on its poral side.3.In the present tapeworm the ovary medium,bean shaped, whereas same in M.orbiuterina is small.4. In the present worm the receptaculum seminis is small in size and posterolateral to ovary,whereas the same in M.orbiuterina is absent.5.In the present form the paruterine organ is large, sac like, in the central medulla, contains numerous eggs, whereas the same in M. orbiuterina is small, almost circular, with large uterus, containing 3-4 eggs.6.The worm under discussion is having the testes 10 in number, whereas the same in M .copsychiare 10 to 13 in number.7.In the present cestode the ovary is medium in size,bean shaped, portal and compact, whereas the same in M. copsychi is small and poral 8.In the present tapeworm the receptaculum seminis is small,posterolateral to ovary, whereas the same in M. copsychi is absent.The noted character are enough, to distinguish these worms, from the earlier species, hence it is desirable to erect a new species for this worm and hence the name Mogheia yasini n.sp.is proposed, in honors of ,the father of the author who was has encouraged so much, for the completion of this work.

Discussion
The genus Mogheia was erected by Lopez-Neyra in 1944, with a type species Mogheia orbiuterina (Moghe, 1933) from the intestine of Turdoides somervillei in India.Later on eight species are added to this genus, as reported in the discussion of earlier species.The present communication deals with the description of a new species, under the same genus as Mogheia shahsdaensis n.sp.fromTurdoide smalcolmis at shahada,M.S. India 1] The worm under discussion, in having the testes 5 in number, comes closer to M. bayamegaparuterina, Cappor, 1967; M. govindi, Shinde, Jadhav and Kadam, 1986; and M. parabhaniensisShinde, Jadhav and Kadam, 1986, but differ from them in many characters, which are as follows 2] In the present tapeworm the scolex is large and oval, whereas the same in M. bayamegaparuterinais large but almost round in M. govindi is quadrangular but small in M. parbhaniensis quadrangular but large.3] In the present cestode the testes are 5 in number, anterior to ovary and in two lines, in central medulla, whereas the same in M. bayamegaparuterina are 4 in number situated lateral and aporal to ovary, in the central medulla; in M. govindi 4 in number, aporal in position, oval in shape and situated in a line and in M. parbhaniensis 5 in number, aporal in position, round in shape and in three lines.4] In the present tapeworm the ovary is large, bilobed, in posterior half of the segment, but differs from M. bayamegaparuterina, which is having the ovary roughly oval and compact; from M. govindi, which is having the ovary compact, oval, in poral half and from M. parabhaniensis in which the ovary is compact round, which a cap of uterus.5] In the present form the cirrus pouch is big in size, oval in shape, at 1/3 from anterior margin of the segment; but differ from M. bayamegaparuterina in which it is not mentioned, from M. govindi which is having the cirrus pouch small in size, oval in shape and at the middle of the segment; from M. parabhaniensis is small in size, elongated, cylindrical and 1/3 from the anterior margin of the segment.6] In the present worm the receptaculum seminis is present which is small, anterolateral to ovary, is absent in all the three other species, which are being compared here.The above mentioned noted characters are distinct and hence the author feels to erect a new species to accommodate these worms, into a new species and hence the name Moghea shahadaensis n.sp. is proposed after the locality.
