Abbottella (Abbottella) wilhelmi (Pfeiffer, 1858)

Plates 4 T–X, 8 D

Type material. Not located.

Type locality. In insulae Haiti. But Pfeiffer continues that it “was collected under stones in moist places near Puerto Plata” [translation].

Other material examined. UF 216149, 3 km N of Madre Vieja, Loma Blanca, Puerto Plata Province, Dominican Republic; UF 216150, 1 km N of Madre Vieja, Loma Blanca, Puerto Plata Province, Dominican Republic, at 80 m; UF 216151, 18 km SE of Rio San Juan, María Trinidad Sanchéz Province, Dominican Republic, at 70 m; UF 184441, Puerto Plata, Puerto Plata Province, Dominican Republic; UF 158837, Puerto Plata, Puerto Plata Province, Dominican Republic; UF 119145, Puerto Plata, Puerto Plata Province, Dominican Republic; GTW 8273a, 15273b, Pico Isabel De Torres, Puerto Plata Province, Dominican Republic; GTW 15273a, Nagua, María Trinidad Sanchéz Province, Dominican Republic; Grego coll., Puerto Plata, Puerto Plata Province, Dominican Republic.

Distribution and habitat. Specimens have been reported from isolated portions of the Cordillera Septentrional at Pico Isabel de Torres near Puerto Plata, Loma Blanca at El Choco, and the north side of the outcrop between Rio San Juan and Cabrera. Thus a large portion of its range is contained within the Parque Nacional Isabel de Torres and the Parque Nacional El Choco. Specimens were collected in rainforest on the Pico Isabel de Torres and elsewhere under limestone rubble in a grassy area with royal palms and evergreens in rolling, karsted hills, in some areas cut over for pasture.

Comparison with other species. See Comparison under A. cf. adolfi adolfi above ( Figure 3 G–I). Abbottella sanchezi ( Figure 4 J–N) is very similar but the spiral sculpture tends to form a carina at the periphery in that species. Abbottella wilhelmi ( Figure 4 T–X) tends to have stronger, wider spiral cords than other species of a similar size and lacks keel-like spiral cords in the umbilicus.
