A NEW GENUS .AND SPECIES OF TREMATODE FROM THE 

 LITTLE BROWN BAT AND A KEY TO THE GENERA OF 

 PLEUROGENETINAE 



By Ralph W. Macy 



College of Si. Thomas, Si. Paul, Minn. 



Among the intestinal parasites of a little brown bat {Myotis 

 lucifugus), collected on February 12, 1934, at St. Peter, Minn., by 

 Gustav Swanson, were 11 specimens of a hitherto undescribed 

 trematode, which was found to belong to a new species of a new genus 

 of Lecithodendriidae. Although the species appears to be more 

 closely related to the members of the Pleurogenetinae than to those of 

 any other group, it can not be referred to any of the existing genera of 

 that subfamily. 



GLYPTOPORUS, new genus 



Diagnosis. — Pleurogenetinae: Suckers subequal; testes entire, 

 situated at level of ventral sucker; intestinal ceca short, reaching 

 only to testes; cirrus sac large, mostly lateral and anterior to ventral 

 sucker; genital pore anterior to ventral sucker and slightly to left of 

 median line of body. Seminal receptacle present. Ovary entire, 

 pre-equatorial, and on opposite side of acetabulum to cirrus sac. 

 Vitellaria pretesticular, follicles large and filhng region between ceca 

 and oral sucker, with tendency toward a single field. Uterus filling 

 large portion of body. Excretory vesicle V-shaped. 



Genotype. — Glyptoporus noctophilus, new species. 



This genus may be distinguished from other genera in the subfamily 

 as shown in the key (p. 323).
