Choeroniscus godmani 

 Godman's Bat 



Godman's bats are found from Sinaloa, Mexico, to Suriname (Fig. 41). The 

 species is monotypic. 



These bats occupy a variety of habitats ranging from primary forest to agri- 

 cultural areas; roosting sites have not been recorded. Food probably includes poUen, 

 nectar, and insects (Gardner 1977). Other than the observation that young seem 

 to be weaned at the beginning of the rainy season, little is known of the reproduc- 

 tive cycle (Wilson 1979). 



Goodwin (1946) listed four specimens from San Jose Province and Gardner 

 et al. (1970) added four more from Cartago and Guanacaste Provinces. LaVal and 

 Fitch (1977) captured and released three at La Selva; however, none were preserved. 



Glossophaga commissarisi 

 Commissaris' Long-tongued Bat 



Commis saris' long-tongued bats occur from Sinaloa and Veracruz, Mexico, 

 to Brazil and Peru. The nominate subspecies, Glossophaga commissarisi commis- 

 sarisi, is found throughout Central America. 



These bats have been collected in a variety of habitats ranging from primary 

 forest to banana groves and clearings. Known roost sites seem to be limited to 

 caves and tunnels (Jones et al. 1972), although we found them to be common where 

 there are no caves or tunnels. Food includes insects, fruit, pollen, and nectar (Gard- 

 ner 1977). The reproductive cycle is one of bimodal polyestry (Wilson 1979). 



This species is quite common at La Selva, where it first was recorded by Mares 

 and Wilson (1971). LaVal and Fitch (1977) captured 81 there. Curiously, we did 

 not encounter G. commissarisi in Braulio Carrillo. 



Specimens examined (12)— Puerto Viejo, Rio Sarapiqm, 300 ft [2 females, 

 UMMZ]; Puerto Viejo, 100 m [1 male, KU]; Finca La Selva, 3 km S of Puerto 

 Viejo, 70 m [1 male, KU; 5 males, 3 females, MSB]. 



Additional records (l)-3 mi N of Heredia, 5,600 ft [1 male, TCWC]. 



Glossophaga soricina 

 Pallas' Long-tongued Bat 



Pallas' long-tongued bats are distributed from Sonora, Mexico, to northern 

 Argentina (Fig. 42). The Costa Rican subspecies, Glossophaga soricina handleyi, 

 is found throughout Central America. 



This is one of the most widespread and abundant species of bats in the tropical 

 lowlands and occurs in almost every available habitat type. It is known to roost 

 in caves, tunnels, hollow trees, buildings, and culvert?; (Tuttle 1976). Food items 

 include insects, fruit, pollen, nectar, and flowers (Gardner 1977). The reproduc- 

 tive pattern is one of bimodal polyestry (Wilson 1979). Howell (1983) summar- 

 ized natural history information. 



This species is common at La Selva, but less so than G. commissarisi. We 

 captured several there in 1973 and 1974, and LaVal and Fitch (1977) recorded 

 23. Although we did not encounter them in Braulio Carrillo, a specimen taken at
