Minchinia to Haplosporidium: M.

genus / HAPLOSPORIDA

Description

cadomensis Marchand & Sprague, 1979. Hap/osporidium parisi Ormieres, 1980; H. /usitanicum Azevedo, 1984; H. heterocirri Caullery & Mesnil, 1899; and H. potamillae Caullery & Mesnil, 1905 need to be designated as species of Minchinia . The following species remain as currently described: M. teredinis Hillman, Ford & Haskin , 1990; H. dentali Arvy , HAPLOSPORI 1949; M. armoricana van Banning, 1977; M. chitonis (Lankester, 1885) Labbe, 1896; H. nelsoni (Haskin, Stauber & Mackin, 1 9 6 6) Sprague, 1978; H. costale Wood & Andrews, 1962; H. louisiana (Sprague, 1963) Sprague, 1978; H. ascidiarum Duboscq-Harant, 1923; H. cernosvitori Jirovec, 1936; H. nemertis Debaisieux, 1920 ; H. caulleryi Mercier & Poisson, 1922; H. sco/opli Caullery & Mesnil, 1899; H. vejdovskii Caullery & Mesnil , 1905; H. marchouxi Caullery and Mesnil,1905; H. pickfordi Barrow, 1961; H. tape tis Vi lela, 1 9 51 ; and H. limnodrili Granata, 1913. As noted by LaHaye et al. (1984} , H. comatulae LaHaye, Holland & Mclean , 1984 appears to be very similar to H. parisi, particularly in terms of the location and ultrastructure of the epispore filaments. However, they did not demonstrate whether the filaments were attached to the posterior end of the spore and whether they were visible as prominent extensions visible in the light microscope. Because of the marked similarity I propose to tentatively consider H. comatulae also to be a species of the genus Minchinia. Haplosporidium tumefacientis Taylor, 1966 appears to be very similar to H. comatulae and H. parisi, therefore it should also be placed in the genus Minchinia. Haplosporidium aselli and H. gammari have been removed from the genus and have become C/austrosporidium asel/ii (Pflugfelder, 1 9 4 8) Larsson, 1987 and C. gammari (Ryckeghem, 1930) Larsson, 1987 (see below). I do not consider H. aulodrili and H. mytilovum to be members of the Haplosporidia because they lack spores with orifices. Thus, with the above proposed changes, there would be 9 species of Minchinia and 15 species of Haplosporidium.

As noted by LaHaye et al. (1984} , H. comatulae
LaHaye, Holland & Mclean , 1984 appears to be
very similar to H. parisi, particularly in terms
of the location and ultrastructure of the epispore
filaments. However, they did not demonstrate
whether the filaments were attached to the
posterior end of the spore and whether they were
visible as prominent extensions visible in the
light microscope. Because of the marked

comatulae also to be a species of the genus
Minchinia. Haplosporidium tumefacientis Taylor,
1966 appears to be very similar to H. comatulae
and H. parisi, therefore it should also be placed in
the genus Minchinia.
Haplosporidium aselli and H. gammari have been
removed from the genus and have become
C/austrosporidium asel/ii (Pflugfelder, 1 9 4 8)
Larsson, 1987 and C. gammari (Ryckeghem,
1930) Larsson, 1987 (see below). I do not
