New taxa and distributional notes on Abbottella and related taxa (Gastropoda: Littorinoidea: Annulariidae) Author Watters, G. Thomas text Zootaxa 2013 3646 1 1 22 journal article 10.11646/zootaxa.3646.1.1 9b6ec282-ff71-4189-81cb-f63930d210de 1175-5326 283728 55F70B5D-79AD-4C77-9164-EFE7126316E8 Abbottella ( Abbottella ) cf. adolfi adolfi (Pfeiffer, 1852) Figures 3 F–I, 9 D 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.
