Fig. 6 in New species and new records of Melayonchis slugs (Gastropoda: Euthyneura: Pulmonata: Onchidiidae)
Fig. 6. Geographic distribution of the six known Melayonchis species. The many blue dots correspond to regions where we collected gastropods since 2010 (with several sites per dot), clearly indicating where we have not found Melayonchis (e.g., Philippines, Sulawesi, Queensland). So far, Melayonchis was only found in the Andaman Islands, on both sides of the Strait of Malacca (western Peninsular Malaysia and eastern Sumatra), Singapore, southern Vietnam, Brunei Darussalam, and Northern territory. The colours used for each species are the same as those used in Figs. 3–5.

A yellow loop turns counterclockwise. A green loop is transitional between a blue loop and a yellow loop. The orientation of the transitional (green) loop is indicated with a red arrow (e.g., at 3 o'clock in C, at 6 o'clock in I, and at 12 o'clock in J). For details about the Melayonchis and Onchidium individuals illustrated here, see Dayrat et al. (2016, 2017).
