NORTH AMERICAN FAUNA 75 



1,520 m near San Jose de la Montana (Starrett and de la Torre 1964) suggests 

 that this species occurs at least seasonally at low and middle elevations there. 



Specimen examined (1)— Puerto Viejo, 100 m [1 male, KU]. 



Additional records (4)— 3 mi N of Heredia, 5,600 ft [1 male, 3 females, 

 TCWC]; San Jose de la Montana, 1,520 m (Starrett and de la Torre 1964). 



Hylonycteris underwoodi 

 Underwood's Long-tongued Bat 



Underwood's long-tongued bats occur from Nayarit and Veracruz, Mexico, 

 to western Panama (Fig. 43). The nominate subspecies, Hylonycteris underwoodi 

 underwoodi, is found in Costa Rica and adjacent areas, north to Veracruz. 



In general, this species is found in forested habitats, frequently at middle ele- 

 vations. Roosts have been found in caves, culverts, and hollow logs (Villa-R. 1967). 

 Individuals feed on insects, pollen, and nectar (Gardner 1977). The reproductive 

 cycle is one of bimodal polyestry (Wilson 1979), but pregnant females have been 

 recorded year around (LaVal 1977; LaVal and Fitch 1977). Biology of this species 

 was summarized by Jones and Homan (1974). 



The type locality is San Jose; the first specimens from Vara Blanca, near Parque 

 Nacional Braulio Carrillo. were reported by Gardner et al. (1970). LaVal and Fitch 

 (1977) captured 15 at La Selva. This is the common glossophagine bat in the region, 

 and we netted it in every habitat sampled. 



Specimens examined (33)— Finca La Selva, 3 km S of Puerto Viejo, 70 m 

 [1 female. L ACM; 1 male. 1 female. MSB]; 1 1 km S. 4.5 km W of Puerto Viejo. 

 270 m [3 males, 2 females, USNM]; 1 km S, 11.5 km E of San Miguel, 680 m 

 [1 male. 5 females, USNM; 1 male, UNA]; 3.5 km S. 1.5 km E of San Miguel, 

 1 .000 m [6 females, USNM]; 5 km E of Vara Blanca. 2.050 m [4 males. 1 female, 

 USNM]; Vara Blanca [1 male. 3 females. LSUMZ]; 1 mi W of Vara Blanca 

 [3 females. TTU]. 



Lichonycteris obscura 

 Brown Long-nosed Bat 



The brown long-nosed bat is a monotypic species found from Belize and 

 Guatemala to Peru and the Guianas. 



Little natural history information is available for Lichonycteris obscura. Most 

 specimens have been taken in forested habitats. Apparently, roosting sites have 

 not been recorded. The diet includes pollen, nectar, and insects (Gardner 1977). 

 In Costa Rica, pregnant females have been taken in the dry season, but the overall 

 reproductive pattern is unknown. 



Goodwin reported two specimens from San Jose Province. Gardner et al. (1970) 

 recorded the first specimens from the Caribbean lowlands at Cariari. Limon Prov- 

 ince. LaVal and Fitch (1977) captured three individuals at La Selva. 



Specimen examined (1)— Finca La Selva. 3 km S of Puerto Viejo. 70 m 

 [1 male. LACM]. 



Additional record (1)— 2.5 km SE of Puerto Viejo [1 female, TCWC].
