Collections were made in T. F. Amazonas (10) and Trujillo (1), during the months of April, June, July, and September. Remarks: In the proposed classification, this new species is tlie first of five species comprising subgroup B, group I of the genus. This group differs from other species of the genus in having a heavily sclerotized sub- triangular median anterior projection of the sternal plate (with a distinct construction an- terior to the first sternal setae) and in having the mediodistal lobe of the palpal tibia rather prom- inent and medium sized. P. tonatii most closely resembles P. paractitisteimts in overall size and in the general shape of the female sternal plate; both species are distinctl\- smaller mites than the other three species of the group, P. actitisternus, P. dusbabeki, and P. grandisoma n. sp. P. tonatii differs from other closely related species in the following characters: posteroventral setae of fe- mur IV, patella IV, and tibia IV of females small, straight, and setaceous rather than large and recurved; female sternal plate with short broadly rounded anterior projection, without lat- eral angular extensions; and first two pairs of dorsal podosomal setae of males distinctly shorter than other three pairs. P. tonatii is re- corded t)'pically from bats of the genus Tonatia. Periglischms paracutisternus Machado-Allison and Antequera, 1971 Fig. 5 Periglischriis paracutisternus Machado-Allison and Antequera, 1971: 12-15. Description: Female: Idiosomal length, 1004 /x; greatest width, 927 /i. Ventral idiosomal setae mostly small to medium sized (length 8-20 /i); however, several pairs just behind genital plate reduced and minute. Sternal plate oval in general shape (median length, 139 /<; greatest width, 104 /(,) with double hat-shaped anterior projection (Fig. 5); ant
