We provisionally refer our specimen to S. l. ludovici pending Luis de la Torre's forthcoming review of the genus. Selected measurements are: total length, 77 mm; length of hind foot, 15 mm; length of ear, 19 mm; length of forearm, 44.8 mm; weight, 26.8 gms; greatest length of skull, 24.2 mm; zygomatic breadth, 14.2 mm; postorbital breadth, 6.3 mm; breadth of braincase, 10.5 mm; length of maxillary toothrow, 6.8 mm.
Uroderma magnirostrum Davis, 1968
In the original description of U. magnirostrum, Davis (1968:680) reported one specimen from Nicaragua—a female in our collection from 3 km N and 4 km W Sapoá, 40 m, Rivas. We have two additional specimens, both from the relatively dry northwestern Departamento de Chinandega. On 8 July 1966, a male (testes 2 mm) was netted under trees along a small stream at San Antonio, 35 m, and a female (one embryo 28 mm in crown-rump length) was netted on 4 March 1968 over a warm spring at a place 4.5 km N Cosigüina, 15 m. Judging from published records, this species is limited in Middle America to the Pacific versant.
Selected measurements of the three Nicaraguan specimens are, respectively: total length, 65, 64, 67 mm; length of hind foot, 12, 11, 14 mm; length of ear, 16.5, 16, 18 mm; length of forearm, 42.2, 41.7, 45.2 mm; weight, 16.2, 13.8, 21.4 (pregnant) gms; greatest length of skull, 22.7, 23.4, 23.8 mm; zygomatic breadth, 12.4, 12.9, 13.1 mm; postorbital breadth, 5.8, 5.5, 5.9 mm; mastoid breadth, 10.9, 11.1, 11.1 mm; length of maxillary toothrow, 7.9, 8.1, 8.6 mm.
Vampyrops helleri Peters, 1866
Specimens.—Boaco: Santa Rosa, 17 km N, 15 km E Boaco, 300 m, 3. Carazo: 3 km N, 4 km W Diriamba, 600 m, 2. Chinandega: Potosí, 5 m, 1; 6.5 km N, 1 km E Cosigüina, 10 m, 1; 4.5 km N Cosigüina, 15 m, 3; Hda. Bellavista, 720 m, Volcán Casita, 13. Chontales: 1 km N, 2.5 km W Villa Somoza, 330 m, 4. Granada: Finca Santa Cecilia, 6.5 km SE Guanacaste, 660 m, 4. Matagalpa: Finca Tepeyac, 10.5 km N, 9 km E Matagalpa, 960 m, 1. Nueva Segovia: 4.5 km N, 2 km E Jalapa, 680 m, 2; 1.5 km N, 1 km E Jalapa, 660 m, 2. Rivas: 2 km N, 3 km E Mérida, 200 m, Isla de Ometepe, 4; 4 km N, 4 km W Sapoá, 40 m, 1. Zelaya: S side Río Mico, El Recreo, 25 m, 3.
Only two specimens of this small white-lined species have been reported previously from Nicaragua—one from 1 km NW La Gatiada, 1300 ft, Chontales (Davis et al., 1964:383), and the other from 3 mi NNW Diriamba, Carazo (Jones, 1964a:507). This bat was relatively rare in collections until the last decade or so. Handley (1966b:766) reported V. helleri as abundant in the lowland areas of Panamá, and we found the same to be true in Nicaragua. We suspect that future investigations in Middle America will reveal this species to be a common member of lowland tropical communities. It is known as far north as southern Veracruz (Carter et al., 1966:494).
Most of our specimens were captured in mist nets set over small streams bordered by gallery forest, or in banana groves. The range of ecological conditions in which this species was taken is represented by the semiarid environment of the Cosigüina Peninsula in northwestern Nicaragua and the humid tropical forest (secondary growth) in the vicinity of El Recreo in the Caribbean lowlands. Pregnant females were captured in March, April, June, July, and August, indicating that this species probably breeds throughout much of the year.
