5. New species 
Two new Hispaniolan Anolis are being described by Williams and Webster. 
In each case there are some special aspects: 
(1) A red-dewlapped sibling of white-dewlapped Anolis cybotes, sympatric 
with the latter in the vicinity of San Jose de Ocoa in the south central 
Dominican Republic, differs minimally in scale characters: the two mid- 
dorsal scale rows on the trunk are usually less enlarged than in cybotes. 
However, it is strongly different at 10 of 22 loci examined electrophoretically. 
Ecologically the two species do not differ impressively, At San Jose 
de Ocoa (ca 1,000 feet elevation) both occur commonly and the habitats for 
each differ enough from year to year and from site to site to make any 
summary statement difficult. Above San Jose de Ocoa, on the southern slopes 
of the Cordillera Central, the red-dewlapped form occurs on bare, open 
hillsides and cybotes only in the small villages (to which it may have 
received artificial transport). Cybotes appears to occur in enclaves 
surrounded by the red-dewlapped species. Below San Jose de Ocoa the red- 
dewlapped species is known from fence rows and a coconut grove, but it now 
is in enclaves and cybotes appears to surround 
(2) A larger sibling of Anolis monticola is now known to occur syntopic- 
ally with the nominate subspecies, It is readily distinguished by colors 
in life as well as size. (It lacks the nape ocelli of monticola and has 
a light line on the side and a red rather than yellow belly.) In scales 
it is sufficiently like monticola that it has become obvious that some of 
the literature records for the latter based on old and discolored specimens 
now are in error, including the specimen on which maximum size for monticola 
has been reported, 
More interestingly, the new species is the third in a very close knit 
group of species distinguished by karyotype in which some of the chromosomes 
have undergone fission, 
A monticola species group has previously been described: it is now 
clear that this divides into two sections. The first is rather diverse and 
dispersed with unfissioned chromosomes and occurs on the northern "island" 
above the Cul de Sac Plain; the second is restricted to the western tip of 
the Tiburon Peninsula of Haiti, two of them wholly syntopic so far as known 
and differing primarily in size and color (monticola and the new species) 
and the third a grass anole, this differing somewhat in shape and climatic 
niche but similar to monticola in size and adjacent in locality. This 
second subgroup, clearly closest relatives on the basis of both karyotype 
and scales, now prove to be one of the more interesting of the sets of local 
species in the West Indies. It is obvious that in the West Indies it is in 
these local isolates that there are surprises still to come.
