(1966:143-144) and described in detail by them under that name. 
The type of gundlachi has been examined by the present author. It 
is also octodentate, but has a much coarser dorsal punctuation, the 
punctures of the pronotum especially running together to form 
grooves. Furthermore, it has a pair of low transverse ridges on the 
head, absent in ciboney, and the elytral intervals are more convex. 
The aedeagus of C. gundlachi has not been examined. 
The two described species of Hispaniolan Canthochilum may be 
told apart at a glance by the shape of the head (figs. 1 and 5), also 
the distal edge of the fore tibiae (fig. 2 and 6), the shagreening of 
the elytra and deeper striae in ciboney , the latter’s lengthened last 
sternite, and, of course, the male genitalia. 
In keeping with a previous tradition in describing species of this 
genus, the new species is given an Amerindian name and is dedicated 
to the Ciboney tribe, which occupied part of Hispaniola and Cuba. 
The third Hispaniolan species of Canthochilum in the MCZ 
material is represented by the hind body of a single male. It is a 
typical Canthochilum , judging by the sternal plates, lateral elytral 
carinae, and aedeagus, but is clearly different from either darlingtoni 
or ciboney in having the elytral intervals more strongly shagreened, 
the striae coarser, the elytra a little more flattened, and the aedeagus 
quite different, with slender parameres and a trilobed projection 
oh the basal piece (fig. 8). The aedeagus is unlike that of any 
Cuban or Puerto Rican species known. The total length of the beetle 
is estimated at 3.3 mm.
