Parachondria (Chondropomorus) dessalinesi ( Bartsch, 1946)

Figures 1 View FIGURE 1. A – H AF–AI, 5 A

Type material. NMNH 471984, holotype.

Type locality. “The hills at Thomazeau in the Cul-de-Sac.”

Type figured. Bartsch, 1946: pl. 2, fig. 3.

Chresonymy. Chondropoma (Chondropomorus) petitianum dessalinesi Bartsch, 1946: 18 –20, pl. 2, fig. 3; Ruhoff, 1973: 61; Watters, 2006: 499–400.

Parachondria (Parachondria) petitianus dessalinesi ( Bartsch, 1946) . Watters, 2006: 46, 399–400.

Distribution and habitat. This species is only known from the type locality, “the hills at Thomazeau.” This is the southern slope of the Chaîne des Matheux/Chaîne du Trou d’Eau between Trou Caiman and Lake Azuei.

Material examined (34 specimens). Haiti. NMNH 471984(1), NMNH 471985(33), both from the type locality.

Redescription. Shell thin but opaque, high-spired, elongate conic. Maximum adult size: 16.2 mm, decollate. Minimum adult size: 14.9 mm, decollate. Adult shell decollated. Protoconch unknown. Teleoconch of 5–5.5 whorls. Axial sculpture of final whorl of numerous (ca. 80) narrow threads. Spiral sculpture of final whorl of ca. 30 low, indistinct cords, most developed as beaded sculpture at intersections with axial threads, which tend to alternate in strength. Overall sculpture rough and weakly fenestrate. Umbilicus bounded by a single cord, smooth within. Suture indented but not channeled. Blunt tufts composed of 1–2 enlarged axial threads, separated by 1–3 nonenlarged axial elements, irregularly spaced. Aperture oval, lip double, rarely single. Inner lip fused to outer lip and nearly obsolete. Outer lip expanded, much narrower facing umbilicus, barely adnate with previous whorl. Posterior auricle absent or barely expanded. Color pattern complex and variable. Base color white or tan. Smudged pale, widely spaced tan axial zig-zags vaguely arranged into spiral bands that continue on both sides of outer and inner lips. Tufts and beads white. Operculum lacking in all specimens examined.

Variation in specimens. The sculpture varies in strength in the few specimens seen but specimens are otherwise quite uniform in characteristics.

Comparison with other species. This is a small, pale species. It closely resembles C. arcisensis from northern Haiti. That species has somewhat coarser sculpture where the spiral cords tend to form weak carinations. Original descriptions. See Bartsch (1946: 18–20).

Etymology. Probably Jean-Jacques Dessalines (1758–1806), leader of the Haitian Revolution and the Emperor of Haiti.
