FIGURE 1 in Revision of the systematic status of Helminthoglypta walkeriana morroensis (Hemphill, 1911) (Gastropoda: Pulmonata)

FIGURE 1. Geographic distribution of Helminthoglypta walkeriana () and Helminthoglypta morroensis () shown as line polygons. Open symbols represent locations of occurrence; filled symbols indicate sites where shells were collected for morphometric analyses (see Table 1 for site descriptions and abbreviations). Projected distribution of H. morroensis beyond documented shell occurrences based on topography, soils, and vegetation similarities with known sites. Shaded regions are communities, as labeled.
