ANTS OF THE DOMINICAN AMBER 
(HYMENOPTERA: FORMICIDAE). 
3. THE SUBFAMILY DOLICHODERINAE

The Dolichoderinae, in particular the species of Azteca and Iri- 
domyrmex, are by a wide margin the most abundantly represented 
ants in the Dominican amber. They are also exceptional in the 
number of genera occurring in the amber but not in the modern 
fauna of the Greater Antilles. In other words the Dolichoderinae 
appear to have undergone a considerable amount of retreat entail- 
ing local extinction since early Miocene times, and for this reason 
alone the fossil species deserve close attention. In the present review 
I have relied principally on the large collections I have assembled for 
the Museum of Comparative Zoology during the past 10 years, 
supplemented substantially by material loaned by Dr. Robert E. 
Woodruff. All of the holotypes (except Dolichoderus dibolia) and 
most of the paratypes have been deposited in the Museum of Com- 
parative Zoology. The holotype of D. dibolia and a few paratypes 
have been placed in the Florida State Collection of Arthropods, 
Gainesville, Florida. Earlier parts of this series have dealt with 
extinct myrmicine genera and the ecitonine army ants respectively 
(Wilson, 1985a, b). 
Dolichoderus 
This genus of large, slender ants is composed today of 8 species 
limited to the moist tropical forests of South America. The colonies 
are mostly or exclusively arboreal. The species to be described 
below is clearly a member of the distinctive attelaboides group, 
which ranges from the Amazonian region of Bolivia north to 
Trinidad.
