NATIONAL MUSEUM Vol. 83 Washington : 1936 No. 2986 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). 49207—36 321
