Remarks.
The
type
of
Choanopoma adolfi
collected by Sallé has apparently been lost. Pfeiffer illustrated it (1854: pl. 48, figs. 5-8); figures 5–7 are only outline drawings but figure 8 is a color figure (refigured here as
Figure 3
F). Bartsch (1946) had no material he could refer to this species and reproduced Pfeiffer’s translated description and his figure 8. As Bartsch noted, Pfeiffer’s
type
locality of
Haiti
must refer to
the Dominican
Republic, which was known as
Haiti
at the time, because Sallé did not collect in
Haiti
proper. The taxon shown here seems to best fit the description and figure of
C. adolfi
of all the
Abbottella
I have examined. It is from the Rio San Juan area in María
Trinidad
Sánchez Province (UF 216151, GTW 7020c). However, if these specimens are indeed
A. adolfi
it is most closely related to
A. wilhelmi
(
Figure 4
T–X), a species found just to the west of Rio San Juan.
Abbottella wilhelmi
(
Figure 4
T–X) is very similar to
A. cf. adolfi
but is smaller and has a different operculum. The operculum of
A. cf. adolfi
is composed of a broad, cup-like, oblique lamella; the operculum of
A. wilhelmi
has a nearly vertical lamella.
Abbottella sanchezi
(
Figure 4
J–N) is also similar but has a vertical lamella on the operculum and the spiral sculpture tends to form a carina at the periphery. Bartsch (1946) described a subspecies from the trail from Samaná to Rio San Juan,
A. a. peninsularis
(see below,
Figure 3
J–L), which differs in having an unbanded outer lip.
