Description:

Figure 43.Distribution of Gudeodiscus Páll-Gergely, 2013 species. Legends: filled triangle, top down: typical Gudeodiscus (Gudeodiscus) phlyarius (Mabille, 1887), filled triangle, top up: “Gudeodiscus phlyarius werneri Páll-Gergely, 2013” (synonym of phlyarius); empty triangle, top up: Gudeodiscus (Gudeodiscus) phlyarius populations showing transitional characters towards werneri in terms of shell shape; empty triangle, top down: atypical Gudeodiscus (Gudeodiscus) phlyarius; empty circle: Gudeodiscus messageri raheemi ssp. n., filled circle: Gudeodiscus (Gudeodiscus?) hemmeni sp. n. (in all localities it co-occurs with Gudeodiscus (Gudeodiscus) messageri raheemi ssp. n.); circle with filled triangle in the middle: co-occurrence of Gudeodiscus (Gudeodiscus) messageri raheemi ssp. n. and atypical Gudeodiscus (Gudeodiscus) phlyarius. The shaded area indicates the area inhabited by Gudeodiscus (Gudeodiscus) messageri messageri (Gude, 1909) and “anterides”, “fallax” and “gouldingi”-like populations of Gudeodiscus (Gudeodiscus) phlyarius. Filled square indicates the position of Phong-Tho, the type locality of Plectopylis verecunda Gude, 1909 (synonym of Gudeodiscus phlyarius). Numbers 1–3 refer to atypical populations assigned to Gudeodiscus (Gudeodiscus) phlyarius. For explanation, see text.
