Rolleia haitensis Bartsch, 1946

Figures 5 A–F , 7 I

Type material. USNM 504088, holotype.

Type locality. Ennery, Haiti.

Other material examined. UF 32863, 9 km NE of “Dufailly” [= Duffalty], Centre Department, Haiti, at 280 m; UF 32777, hill W of waterfall, 2 km W of “Saut-d’Eau” [= Haut Saut De Eau], Centre Department, Haiti, at 440 m; UF 236258, 2 km SW of Trou Forban, L’Ouest Department, Haiti.

Distribution and habitat. Apparently limited to the Montagnes Noires range. Specimens were found in talus and in leaf litter in cut over forest, some in deep, wet ravines. Confusingly, there is a Dufailly and a Saut-d’Eau in the vicinity of Ennery (the type locality) in Artibonite Department, and indeed Saut-d’Eau has a famous waterfall, but the correct UF localities are Duffalty and Haut Saut De Eau based on the details of the collection records. These records extend the range of this species ca. 80 km to the southeast along this mountain range.

Comparison with other species. Rolleia haitensis has a more adnate final whorl than does R. martensi (Maltzan, 1888) from the Ennery region of Haiti and has more numerous axial threads. Rolleia oberi ( Figure 5 G– N) is smaller than R. haitensis or R. martensi and has the axial sculpture produced into erect lamellae rather than threads; the outer lip is much more expanded in R. oberi as well.
