GREGARINA MUNIERI (Schneider) Labbe 

 [Figures 128, 147] 



1875 Clepsidrina Munieri Schneider 1875 :574-8 



1899 Gregarina munieri Labbe 1899 :9-10 



Gregarina: Sporonts biassociative, elongate ellipsoidal. Length 

 and width not given. Ratio length protomerite : total length primite 

 : : 1 : 6 to 1:7; width protomerite : width deutomerite : : 1:7. 

 Protomerite cylindrical, flattened anteriorly, a little wider than high, 

 less than 1.5 times, slight constriction at septum. Deutomerite cylindri- 

 cal, ending bluntly or tapering slightly from middle and ending in a 

 broad but rather pointed extremity. Epimerite a small spherical papilla 

 situated upon the apex of a short conical projection of the protomerite of 

 the cephalont. Endocyte reddish orange. Nucleus spherical, with one 

 karyosome. 



Cysts ovoidal. Spore ducts 3 to 6, reddish, very short, less than the 

 radius of the cyst in length. Spores extruded in chains, spores barrel 

 shaped, cylindrical, dilated through middle, terminating bluntly. 



Taken at Roscoff, France. Hosts: Timarcha tenebricosa (F.) ; 

 Chrysomela violacea (Goeze) and C. haemoptera L. Habitat: Intestine. 



Schneider's argument concerning the species in question speaks for 

 itself and is quoted here (1875:575) : 



"'Dans le tube alimentaire de divers Coleopteres, notamment du Lucanus 

 parallelopipedus, de plusieurs Melasomes et de la Timarcha tenebricosa, j'ai trouve 

 abondamment une espece de Vers intestinaux, dont je joins ici le dessin.' Dufour, 

 1826. 'L'espece que j'ai dit habiter des entrailles de divers Coleopteres, merite, a 

 cause de sa forme, le nom Conica.' Dufour, 1828. Si maintennant on se reporte a 

 la figure indiquee par L. Dufour, on n'y trouve pas la designation de 1'hote de 1'in- 

 dividu represente; la legende portant simplement cette mention: 'Vers intestinaux 

 trouves dans le tube alimentaire de divers Coleopteres.' II n'y a done aucun indice 

 que 1'auteur ait plus particulierement vise 1'espece qui nous occupe, et comme il 

 cite d'abord le Lucanus parallelopipedus, c'est a la Gregarine de ce Melolonthide qu'il 

 conviendra de reserver 1'epithete de Conica. Quant a 1'espece actuelle, je 1'ai dediee 

 a mon excellent ami M. Munier Chalmas ." 



The species which Dufour found in Lucanus parallelopipedus is the 

 species now named Actinocephalus conicus (Dufour) Frantzius.
