BIG RED BAT LASIURUS EGREGIUS (VESPERTILIONIDAE) IN HONDURAS JOSE´ M. MORA Centro Zamorano de Biodiversidad and Carrera de Desarrollo Socioecon´omico y Ambiente, Escuela Agr´ıcola Panamericana, El Zamorano, Honduras Correspondent:
[email protected] ABSTRACT—The big red bat, Lasiurus egregius, was known from only four localities in Panama, French Guiana, and Brazil. I report a fifth locality from eastern Honduras, extending the known range >1,200 km to the northwest, well into Central America. On 9 May 1998, I captured one male and one female in a mist net near Guayabo de Catacamas, Olancho, Honduras. Both specimens were caught over water. The female was lactating and the male was reproductively inactive. This brings the total number of specimens of L. egregius to six worldwide. RESUMEN—El murci´elago rojo Lasiurus egregius se conoc´ıa solamente de cuatro localidades en Panam´a, Guayana Francesa, y Brasil. Reporto una quinta localidad del oriente de Honduras, la cual extiende la distribucion ´ conocida m´as de 1,200 km al noroeste, en pleno interior de Centroam´erica. El 9 de mayo de 1998 captur´e un macho y una hembra en una red de seda cerca de Guayabo de Catacamas, Olancho, Honduras. Ambos espec´ımenes fueron capturados sobre el agua. La hembra estaba lactando y el macho no present´o actividad reproductiva. Se eleva el numero de espec´ımenes mundiales de L. egregius a seis. ´ The big red bat, Lasiurus egregius, is a distinctive vespertilionid known from Armila (8841 0 N, 77827 0 W; United States National Museum, USNM 11175), Provincia de San Bl´as, Panama; 9.5 km S, 11.5 km W Sinnamary (5828 0 N, 53800 0 W; Carnegie Museum of Natural History CM 88677), French Guiana; and two Brazilian records, one from Mocambo (=Bel´em; 01827 0 N, 48829 0 W; USNM 392993), Par´a, and one from an unspecified locality (Zoologisches Museum der Humboldt-Universitat zu Berlin, ZMB 3762, type specimen) in Santa Catarina, Brazil (Peters, 1871; Fairchild and Handley, 1966; Handley, 1966; Williams et al., 1990; Paynter and Traylor, 1991). Herein, I report a new locality for L. egregius from eastern Honduras, which extends its known range >1,200 km to the northwest, well into Central America. I mist-netted bats in an extensive region of evergreen forests on 9 May 1998 near Guayabo de Catacamas (14843 0 130 00 N, 85822 0 720 00 W, ca. 300 m elevation), Depar-
tamento de Olancho, Honduras. Four 12-m-long nets were positioned inside the forest under canopy cover, near the edge of a pasture. Two of the nets were set over the Guayabo stream, ca. 50 m from the edge of open pasture. I captured eight bats, including two L. egregius, one of each sex. The female was captured at 1850 h and the male followed in the same net at 2020 h. Both were taken at ca. 2 m above the stream. The moon phase was near full but did not illuminate the nets, which were in darkness at the level of the forest floor. The female was lactating while the male was reproductively inactive. External measurements (mm) and mass (g) of female and male, respectively, are as follows: length of head and body, 68.0, 70.0; length of tail, 62.0, 65.0; length of hind foot, 11.0, 11.0; length of ear, 18.0, 18.0; length of forearm, 50.0, 51.0; mass, 16.0, 17.0. Both specimens were prepared as study skins and skulls and are deposited at Universidad de Costa Rica (male, collector

number JM21998A, collection number UCR 2067) and Universidad Nacional Auto´ noma de Honduras (female, collector number JM24498A, collection number UNAH 1456). The distinctive coloration of pelage and length of forearm in the Honduran specimens were compared with descriptive information for L. egregius in Handley (1960, 1996), Carter and Dolan (1978), and Reid (2009). Coloration of dorsal apical band is rufous red with a wide subapical buffy orangish band on head and neck region especially; darkest on tail membrane. Underside is similarly red with a narrow buffy band. This coloration matches exactly the one described by Reid (2009). There are four known specimens of this species, of which three are female. The holotype is a male, length of its forearm (mm) varies in reports as 47.0 (Peters, 1871), 48.0 (Handley, 1960), and 49.3 (Carter and Dolan, 1978). Williams et al. (1990) reported length of forearm of 45.3 mm for a female from French Guiana. The Honduran big red bats have longer forearms (mm), as do those from San Blas, Panama (49.9), and Mocambo (=Bel´em), Brazil, (50.3). Both forearms of the dry study skin from French Guiana were remeasured (right, 45.5 mm; left, 45.7 mm) and support the length reported previously (T. J. McCarthy, in litt.). The big red bats from Honduras bring the total number of known specimens for L. egregius to six. Williams et al. (1990) reported capturing L. egregius in French Guiana over a stream surrounded by open, grassy flats. The two Honduran big red bats also were captured over water but inside dense forest. Species of other bats captured with L. egregius in Honduras included Artibeus jamaicensis, Carollia castanea, C. sowelli, C. perspicillata, Phyllostomus hastatus, and Sturnira lilium. I thank L.

[email protected] ABSTRACT—In total, 14 new records of birds are reported from coniferous forests and other habitats in the municipality of Nanacamilpa, Tlaxcala, Mexico. These additional records reinforce the supposition that the region is important with respect to conservation of avian diversity in Mexico.
