FROGS OF COLOMBIA — COCHRAN AND GOIN 



189 



At present we can recognize 47 species of Hyla in Colombia, and 

 these are arranged into 22 groups. Surely when additional studies 

 have been made on the frogs of other geographic areas in South 

 America there will be some rearrangement of the groups we here 

 recognize, but for the time being all we can do is to arrange the 

 Colombian species into such natural groups as we can, and when 

 possible, indicate the relationship of our species groups to extralimital 

 forms. 



We do not believe it advisable to present a key to the entire list 

 of species of Colombian Hyla; instead, we have attempted to prepare 

 adequate diagnoses for each of the species groups and have then 

 presented a key to the Colombian species within each group. 



The groups we here recognize in Colombia and the number of 

 Colombian species now known in each group are as follows: 



1. lanciformis group, 1 species 



2. crepitans group, 1 species 



3. maxima group, 2 species 



4. geographica group, 2 species 



5. phantasmagoria group, 1 species 



6. carri group, 1 species 



7. buckleyi group, 2 species 



8. albomarginata group, 2 species 



9. punctata group, 4 species 



10. granosa group, 3 species 



11. squalirostris group, 1 species 



12. rubra group, 3 species 



13. palpebrogranulata group, 1 species 



14. labialis group, 3 species 



15. variabilis group, 3 species 



16. parviceps group, 2 species 



17. marmorata group, 1 species 



18. phlcbodes group, 1 species 



19. minuta group, 1 species 



20. microcephala group, 3 species 



21. leucophyllata group, 8 species 



22. hobbsi group, 1 species 



1. LANCIFORMIS group 



This group consists of large tree frogs with a white margin on the 

 upper lip, pointed heads, and reduced webbing between the fingers. 

 Along with Hyla lanciformis, at least two other forms are in this 

 group, H. mulitfasciata of northeastern South America and H. boans 

 of southeastern Brazil.
