Systematics.—The generalized mesosome of this species makes 
it rather similar to a large number of species, but the appendicles 
of the apical lobe of the basistyle are distinctive. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly longer than twice the 
basal width; clothed with fine setae in addition to the normal, long 
setal pattern. Apical lobe of the basistyle prominent, undivided and 
also clothed with fine setae. Appendicles of the apical lobe as follows: 
basal rod strong, straight, and bluntly rounded; median rod more 
robust, and slightly longer than the basal rod, and with a prominent 
terminal hook; apical rod more slender than the median or basal rods 
and with a prominent terminal hook; leaf moderate in size, obovate; 
two accessory setae present, one straight, the other longer and gently 
hooked; a small, straight seta may also be next to the leaf. Dististyle 
normal. Tenth sternite crowned with a dense tuft of short, pointed 
spines; basal arm moderate in length, gently curved; one to two cercal 
setae present. External process gradually tapering to a point, slightly 
exceeding the ventral cornu in length. Ventral cornu dentiform, 
slightly larger than, and close to the teeth of the median process. 
Median process with about five distinct, sharply pointed teeth. Basal 
process short, straight, and bluntly rounded. 
Larva: Antenna fusiform; a short, reduced tuft located near the 
middle. Postclypeal head hair 4 short, single; frontal head hairs 5, 6, 
and 7 long, multiple. Mentum with about 21 teeth; the apical tooth 
broad and large, the lateral teeth progressively smaller apically. 
Body glabrous. Comb with numerous scales in a patch; each scale 
rounded apically and fringed with subequal spinules. Siphonal index 
about 4.0; five siphonal tufts present on the siphon, the apical and 
subapical tufts being double, the basal tufts multiple and located 
within the pecten. Pecten with about seven teeth, restricted to the 
basal third of the siphon; apical tooth considerably separated from the 
rest of the pecten. Anal segment completely ringed by the saddle. 
MATERIAL EXAMINED.— Eight adult males and associated terminalia 
from Jamaica, six from Puerto Rico, and one from Colombia. 
DistrisuTion.—This species has been reported from Jamaica and 
Puerto Rico. The author has seen one specimen in the U.S. National 
Museum collection from Bogoté, Colombia (RB62 133).
