Species Ototylomys phyllotis Merriam 1901

Discussion: Tylomyini. Emended Definition—Large-sized tylomyine rodents, pelage somber gray to grayish-brown, tail nearly naked; cranium with moderately long, tapering rostrum and flat dorsal profile; jugal absent or tiny and irregularly formed, zygomatic processes of maxillary and squamosal in contact; carotid circulation derived (character state 3 per Carleton, 1980); basihyal with large, attenuate entoglossal process, vertebral column with 14-15 thoracics and 6 lumbars ( Carleton, 1980); M1 rectangular, anterocone broad and deeply bifurcate, lingual and labial conules subequal to primary cusps, M3 rectangular and resembling M 2 in size and enamel configuration; three complete and five-nine incomplete transverse palatal ridges ( Carleton, 1980); accessory reproductive glands with one pair of preputials, ampullaries compact and coiled, vesiculars present and highly modified ( Arata, 1964; Lawlor, 1969), ductus deferens with distal ampulla ( Arata, 1964; Carleton, 1980); urethral process absent ( Ototylomys ) or rudimentary ( Tylomys ), dorsal papilla absent ( Hooper, 1960). Contents— Ototylomys Merriam, 1901 ; Tylomys Peters, 1866 . Closedly related to Tylomys according to morphological features ( Carleton, 1980; Hooper, 1960; Lawlor, 1969; Merriam, 1901 b) and to albumin immunological distances ( Sarich, 1985).
