Distribution and habitat.
Collections at UF enable us to limit Pfeiffer’s imprecise “
In insulae
Haiti
.” The species is known only from Loma Catalina, an outcrop of the Cordillera Septentrional southeast of Sosuá. Much of this area is contained in the Parque Nacional El Choco. The
type
locality is herein restricted to
the Dominican
Republic, Puerto Plata Province, Loma Catalina.
Comparison with other species.
This species is similar to
A. abbotti
(
Figure 3 A–E
) but differs in having finer, less serrate sculpture, less developed keels, and a less fluted outer lip.
Remarks.
This species is perhaps unique among
Abbottella
in possessing a periostracum although it is lost in most specimens. On fresh examples this periostracum forms short bristles at the junctures of the axial and spiral sculpture. The degree of fluting and serration of the outer lip varies greatly—some specimens show virtually no fluting.
