Abstract

This paper presents an investigation of material collected during four intensive collecting trips of land snails in French Guiana from 1995 to 2020 and deposited in the French National Museum of Natural History collections. This material forms the basis of the following novelties: four families are reported for the first time from French Guiana: Diplommatinidae, Cystopeltidae, Thysanophoridae and Strobilopsidae; three native species: Lyroconus plagioptycha (Helicoidea, Thysanophoridae), Pupisoma macneilli (Pupilloidea, Valloniidae) and Strobilops morsei (Pupilloidea, Strobilopsidae) and one introduced species Diplosolenodes occidentalis (Veronicelloidea, Veronicellidae) are reported for the first time from French Guiana; five new species are described: Adelopoma quasimodo Gargominy, sp. nov. (Cyclophoroidea, Diplommatinidae), Lilloiconcha galbao Gargominy, sp. nov. (Punctoidea, Cystopeltidae), Protoglyptus bernicolae Gargominy, sp. nov. (Orthalicoidea, Bulimulidae), Pseudosubulina santi Gargominy, sp. nov. (Testacelloidea, Spiraxidae), and Happia decaensi Gargominy, sp. nov. (Scolodontoidea, Scolodontidae). Finally, Drymaeus surinamensis Vernhout, 1914, syn. nov. is considered as a new synonym of Mesembrinus lusorius (L. Pfeiffer, 1855), and Drymaeus arcuatostriatus (L. Pfeiffer, 1855) is proposed as the new identification of Drymaeus meesi sensu Tillier, 1980 non Breure, 1976.
