Stumira ludovici 

 Anthony's Bat 



Anthony's bats are widely distributed from Sinaloa and Tamaulipas, Mexico, 

 to Peru and Bolivia (Fig. 59). The nominate subspecies, Stumira ludovici ludovici, 

 is found throughout Central America (de la Torre 1961). The systematic status 

 of this species is not well understood; it is almost surely a composite as currently 

 recognized in the literature. True 5. ludovici probably are restricted to northern 

 South America. The Central American bats under discussion here may prove to 

 be a distinct species, for which the name S. hondurensis (Goodwin 1940) is 

 available. 



Although Anthony's bat inhabits a variety of forest types, it is frequently more 

 common at intermediate elevations. Nothing is known about roosting sites. At 

 Monteverde, Dinerstein (1986) found S. ludovici feeding on the fruits of 29 species 

 of plants. The reproductive cycle is the familiar one of bimodal polyestry (Wilson 

 1979). 



Goodwin (1946) reported two specimens from Agua Buena, Puntarenas Prov- 

 ince. Starrett and de la Torre (1964) added one from Volcan Turrialba, Cartago 

 Province. Mares and Wilson (1971) reported two from near San Vito de Java, Pun- 

 tarenas Province. LaVal and Fitch (1977) caught one at La Selva. We found them 

 to be fairly common at middle and higher elevations in Braulio Carrillo. Three 

 of the females we caught in April were pregnant. 



Specimens examined (11)— Finca La Selva, 3 km S of Puerto Viejo, 70 m 

 [1 male, KU]; 11 km S, 4.5 km W of Puerto Viejo, 270 m [1 male, UNA]; 1 km 

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

 5 km E of Vara Blanca, 2,050 m [2 females, USNM]; 2 km N, 0.5 km E of 

 Sacramento, 2,600 m [1 female, FMNH]. 



Additional records (3)— 3 mi N of Heredia, 5,600 ft [3 females, TCWC]. 



Stumira luisi 

 Luis' Bat 



Previously confused with Stumira lilium, Luis' bat was recognized only recently 

 as a distinct species (Davis 1980). The type locality for S. luisi is Cariblanco in 

 Alajuela Province, Costa Rica, and it is now known to occur from Costa Rica to 

 Peru. 



Our specimens came from wet forest, and the distribution of the known 

 specimens suggest this as the primary habitat. Nothing is known about the natural 

 history of these bats due to their confusion with 5. lilium. Presumably they are 

 frugivorous like their congeners. None of our specimens evidenced any reproduc- 

 tive activity. Our specimens all came from over a small stream through pasture 

 land in an otherwise primary forest zone. Paratypes are known from Limon Prov- 

 ince, so finding them in the park is not surprising. 



Specimens examined (4)— 1 km S, 1 1 .5 km E of San Miguel, 680 m [1 male, 

 2 females, USNM; 1 female, UNA].
