Abbottella (Abbottella) sanchezi Bartsch, 1946

Figures 4 J–N, 9 C

Type material. USNM 504092, holotype.

Type locality. 2 miles northwest of Sánchez, Dominican Republic.

Other material examined. UF 215988, 5 km ENE of Sánchez, Samaná Province, Dominican Republic; UF 236224, 2 km W of Sánchez, Samaná Province, Dominican Republic; UF 215991, 3 km E of Samaná, Samaná Province, Dominican Republic; UF 215992, 15 km W of Samaná, Samaná Province, Dominican Republic; UF 215989, 9 km E of Las Terreras, Samaná Province, Dominican Republic; UF 215990, 3 km SW of Las Terreras, Samaná Province, Dominican Republic; UF 216143, 2 km W of Los Cacaos, Samaná Province, Dominican Republic; UF 216154, 40 km [4 km?] NE of Sánchez, Samaná Province, Dominican Republic, 270 m; GTW 7020a, near cave, Samaná Province, Dominican Republic; GTW 14791a, Samaná Peninsula, Samaná Province, Dominican Republic; Grego coll., Sánchez, Samaná Province, Dominican Republic.

Distribution and habitat. Sierra de Samaná of the Cordillera Septentrional. Both coasts of the Samaná Peninsula, from at least Sánchez to Los Cacaos in the south, and Las Terrenas in the north. Most specimens were collected in association with limestone boulders, leaf litter, and talus in tropical forest, also near caves; some sites have been cleared for cocoa groves. I believe the record for UF 216154 of 40 km NE of Sánchez is an error for 4 km.

Comparison with other species. Abbottella wilhelmi ( Figure 4 T–X) is very similar but the spiral sculpture does not form a keel at the periphery. Abbottella sanchezi ( Figure 4 J–N) differs from A. samanensis in lacking the enrolled axial side of the outer lip.
