          Abstract

          Abstract: Mormoopid bats are distributed from southern United States of America to Brazil and comprise the genera Mormoops and Pteronotus. Although forms of Mormoops in Bahia, Brazil were described for the Quaternary, only some of the extant species of Pteronotus occur in this country, including P. gymnonotus. The species distribution ranges from southeastern México to northeastern Bolivia and central Brazil. This work presents information about food preference, reproduction, and the ectoparasitological fauna of P. gymnonotus in the state of Ceará. Fieldwork took place over ten consecutive days in the rain and dry seasons, in 2000, 2012, 2013, and 2019, on trails within the Serra das Almas Private Natural Heritage Reserve. A total of 14 P. gymnonotus specimens were caught in the three main phytophysiognomies present in the region. They were inspected for ecto and endoparasites, and fecal material was collected and analyzed under a light microscope. Of the total collected females, four were pregnant and one was lactating in January, during the rain season. No food residues or evidence of endoparasites were observed in the gastric content of the animals. Regarding the fecal samples, fragments of insects were found and identified as belonging to the orders Coleoptera and Lepidoptera. Seven individuals were infested with ectoparasites of the subfamily Acari and newly described associations with Diptera genera are presented. Due to the scarcity of data about these bats in the Caatinga biome, data reported here help explain the ecological interactions of P. gymnonotus in this semiarid area in Brazil.

          Resumen: Los murciélagos Mormopidos se distribuyen desde el sur de los Estados Unidos de América hasta Brasil y comprenden los géneros Mormoops y Pteronotus. Aunque las formas de Mormoops son conocidas para el Cuaternario de Bahía, Brasil, solamente algunas de las especies recientes de Pteronotus se encuentran en este país. La distribución de la especie comprende desde el sureste de México hasta el noroeste de Bolivia y centro de Brasil. Este estudio presenta información sobre la preferencia alimentaria, reproducción y fauna ectoparasitológica de P. gymnonotus en el Estado de Ceará. El trabajo de campo se llevó a cabo durante diez días consecutivos en las estaciones lluviosa y seca en los años 2000, 2012, 2013 y 2019 en senderos dentro de la Reserva Privada del Patrimonio Natural Serra das Almas. Se capturaron un total de 14 especímenes de P. gymnonotus en las tres principales fitofisionomías presentes en la región. Fueron inspeccionados en busca de ecto y endoparásitos y el material fecal se recogió y analizó con un microscopio óptico. Del total de hembras recolectadas en enero, cuatro estaban preñadas y una en lactancia, durante la época de lluvias. No se observaron residuos de alimentos ni evidencia de endoparásitos en el contenido gástrico de los animales. En cuanto a las muestras fecales, se encontraron fragmentos de insectos que se identificaron como pertenecientes a los órdenes Coleoptera y Lepidoptera. Siete individuos encontraron infestados por ectoparásitos pertenecientes a la subfamilia Acari y se presentan nuevas asociaciones con géneros del orden Diptera. Debido a la escasez de datos sobre estos murciélagos en el Bioma de Caatinga, los datos presentados aquí ayudan a comprender las interacciones ecológicas de P. gymnonotus en una zona semiárida de Brasil.
