Fig. 9 in Systematic revision one clade at a time: A new genus of onchidiid slugs from the Indo-West Pacific (Gastropoda: Euthyneura: Pulmonata)
Fig. 9. Geographic distribution of the two known species of the genus Marmaronchis. The red and dark blue dots correspond to the records for each species from the material included in the present study (the same colour are used on the phylogenetic trees represented in Figs. 1–4). The dark red dot (Ambon, Indonesia) corresponds to a record of Marmaronchis vaigiensis for an old specimen for which no DNA sequences was available (Dayrat, 2010). The four green dots corresponds to type localities of M. vaigiensis and its synonyms. The black dots correspond to paralectotypes of synonyms of M. vaigiensis. The yellow dot corresponds to the type locality of M. marmoratus. The many light blue dots correspond to regions where we collected gastropods in the past few years and where Marmaronchis was not found (acknowledging that it may have been missed in some of them). The orange dot (Guam) corresponds to a record of a Marmaronchis species (likely M. viagiensis) based on a picture and so it is not included within the species distribution area (see Discussion). Finally, the coloured areas correspond to hypothetical ranges based on known records.
