Aegistohadra rara (Wang and Parsons, 2021)

    Collected in forest and mountains, N. He Kou, Yunnan, Peoples Republic of China 2017. Dmax dextral 30.1mm; sinistral 31.8mm. This name replaces Helix (Camaena) contractiva var. minor Bavay and Dautzenberg, 1909a: 171- 172 <https://www.biodiversitylibrary.org/page/27393332> [unfigured], which has countless senior homonyms. Wang and Parsons discovered a syntype (dextral) from Muong-Bo, Vietnam in the Dautzenberg Collection at the Royal Belgian Institute of Natural Sciences (RBINS MT709), which they figured for the first time. Two dextral and two sinistral shells from S. E. Yunnan Province were also treated. First collected by Colonel Louis Gabriel Martin Messager (see Breure and Páll-Gergely, 2019). Lee Collection.
