Mormoops megalophylla megalophylla (Peters)
Peters' Leaf-chinned Bat
1864. Mormops megalophylla Peters, Monatsb. preuss. Akad. Wiss., Berlin, p. 381, type from southern México.
Distribution in Tamaulipas.—Throughout state, except possibly west of the Sierra Madre Oriental.
Specimens from the Sierra de Tamaulipas were taken in mist nets in which Pteronotus rubiginosus, Lasiurus borealis, or Centurio senex also were captured. The specimen from Rancho Santa Rosa was shot as it flew at a height of six feet.
Tamaulipan specimens of Mormoops megalophylla are here assigned to M. m. megalophylla instead of to M. m. senicula following Villa and Jimenez (1961:503), who regarded senicula as indistinguishable from megalophylla.
Weight of four specimens from the Sierra de Tamaulipas averaged 16.2 (15-18) grams.
