Mimon crenulatum (E. Geoffroy)

VOUCHER MATERIAL: 7 females (AMNH *267114, *267115, *267437, *267887, *267889; MNHN *1995.1032, 1995.1033) and 10 males (AMNH *267111, 267113, *267880, 267884, *267885, *267886, 267888; MNHN *1995.1034, *1995.1035, *1995.1036); see table 26 for measurements.

IDENTIFICATION: Useful descriptions and measurments of Mimon crenulatum were provided by Handley (1960), Goodwin and Greenhall (1961), Husson (1962, 1978), Hill (1964), Genoways and Williams (1979), Swanepoel and Genoways (1979), Gardner and Patton (1972), Hall (1981), Brosset and Charles­Dominique (1990), and Pedro et al. (1994). Of the five subspecies recognized by Koopman (1994), M. c. crenulatum occurs from Trinidad and eastern Venezuela throughout the Guianas to southern Amazonian Brazil. However, we follow Gardner and Patton (1972) in regarding M. koepckeae (from the highlands of central Peru) as a distinct species contra Koopman (1978, 1993, 1994).

Our voucher material conforms with previous descriptions of Mimon crenulatum crenulatum . Measurements of Paracou specimens generally fall within the range of variation previously documented for Guianan populations ( Husson, 1962, 1978; Hill, 1964; Genoways and Williams, 1979; Brosset and Charles­Dominique, 1990), although some of our males are slightly smaller in some dimensions than specimens previously reported from the region.

FIELD OBSERVATIONS: All of the 17 Mimon crenulatum we captured at Paracou were taken in ground­level mistnets: 9 in welldrained primary forest, 4 in swampy primary forest, and 4 in creekside primary forest. An unusually large proportion (88%) of captures were in the very early evening, before 19:00 hours.
