. Bonner zoologische Monographien. Zoology. 47 lacrimal inflation. Zygomatic arches lacking in all species. Basisphenoid more or less arched, skiill base ahnost at the same level as palate (in German literature: orthocran). both in the upper and in the lower jaw two pairs of incisivi present; upper incisors similar to Lionycteris (I1»I2), the lower ones equal m size, with trifid edge, the width of a small gap between 12 and lower canine tooth corresponds to the crown width of the 12. Premolars with three cusps (not monocuspid as in Lionycteris). Anterior premolar separated from canmus by a diastema of its own length. Molar teeth still with functional masticatory surfaces. L. thoniasi: Posterior palate edge V-shaped; incisors and anterior edge of the premaxillaria in top view flat and ahnost straight. Basisphenoid pits vaulted. Palate length less than half the total length of skull. Last upper premolar with Ungual cusp, givmg the tooth a T- shaped appearance from top view. Anterior lower premolar with posterior (hooked) cusp. L. mordax (): Posterior palate edge U-shaped; incisors and front edge of the premaxillaria pointed anteriorly in top view. Basisphenoid with deeply vaulted pits. Palate approximately half the total skull length. Last upper premolar without lingual cusp, thus appearing narrow from above. Anterior lower premolar without posterior cusp. L robusta (): Posterior margin of the palate U-shaped; anterior edge of the premaxillaria similar to L. thomasi, but a Httle more pointed. Basisphenoid only flatly vauhed. Palate approximately half the total skull length. Last upper premolar witli a well developed Imgual cusp, thus appearmg triangular in top view. Anterior lower premolar with well developed hooked posterior cusp. Teeth: dental formula - 2 3 1 - - 3 4 5 6 7 12-1-234567. 10 mm : Lonchophylla mordax, H skull lateral view.
