New Humboldtiana species

Recently a paper was published by Mejía et al., on species from northern Mexico. “Three new species of the genus Humboldtiana are described. The presence of a mantle mottled with dark spots allocates H. paquimei from Chihuahua to the subgenus Gymnopallax. On the other hand, the embryonic whorls, a smooth and granular sculpture distributed over the shell surface, allocate H. wixarika from Jalisco and H. aurea from Chihuahua to the subgenus Humboldtiana s.s. The newly described species are distinguished from other species of the genus by the combination of shell and anatomical characters and by their geographic distribution”.

The paper is dedicated to the memory of the late Dr Fred G. Thompson, a specialist of Mexican and Central American non-marine molluscs.

New edition of ‘2400 years’

Today an updated version of Coan & Kabat’s ‘2400 years’ appeared:

“Gene Coan and I are pleased to announce that the 2019 edition of “2,400 Years of Malacology” – a catalog of biographical and bibliographical articles about those who studied and collected mollusks and related files – is now on the website of the American Malacological Society:
Please note that the home of the AMS website has recently changed, so any links or bookmarks will need to be updated.
The 2019 edition is 1,710 pages.  It includes four additional documents containing (1) collations of a number of important references for malacological systematists (111 pages); (2) collation of the Systematisches Conchylien-Cabinet (1837-1920) (65 pages); (3) collations of significant malacological journals (62 pages), and (4) an updated version of the “Annotated Catalog of Malacological Meetings, Including Symposia and Workshops in Malacology” (145 pages)”.
As usual, this is a very useful work for those who want to know who is behind all those names that are dispersed in the malacological literature, either as authors or as collectors or other persons of interest.

New Chilean Charopid

Araya & Miquel recently published a paper in which they introduced a new micromollusc: “Stephacharopa paposensis n.sp. is described from shells collected in coastal areas of Paposo, Región de Antofagasta, northern Chile, associated with native bromeliads and cacti living among rocks and coarse sand. This is the second species of Stephacharopa found in northern chile and one of the northernmost species of Charopidae found in this country”.

Micromolluscs have been largely overlooked so far in the Neotropical fauna, and much more novelties are to be expected when malacologists focus on these groups during collecting in the various countries.
