nom. nov.

Chloritis khammouanensis Inkhavilay & Panha View in CoL nom. nov.

Megalacron huberi Thach, 2017: 53, 54, figs 741-743. [non Chloritis huberi Thach, 2016: 72, 73, figs 49, 407-410]. Type locality: Thakhek, Khammouane Province, South Central Laos.

Etymology.

The species name “khammouanensis” is from the type locality of the type specimens in Laos.

Material examined.

Holotype MNHN-IM-2000-33214 (Fig. 50E). Specimens from Tam Xang Cave, Thakhek District, Khammouan Province (Fig. 50F).

Distribution.

Known only from the type locality in Laos ( Thach 2017).

Remarks.

This species was originally placed in the genus Megalacron Rensch, 1934. It seemed inappropriate since all the known members are distributed in the Bismarck and Solomon Islands. Moreover, the subfamily Papuninae where Megalacron belongs has a restricted distribution in New Guinea, Australia and Melanesia ( Schileyko 2003b: 1605, 1606). With a medium shell size, depressed helicoid, expanded lip and rimate umbilicus, they are practically identical to the generic characters of Chloritis s.l., although this placement requires further anatomical study for confirmation.

By relocating Megalacron huberi Thach, 2017 to the genus Chloritis , it becomes a junior secondary homonym of Chloritis huberi Thach, 2016 (see below). According to the ICZN guideline ( ICZN 1999: Arts 57.3.1 and 60.3), the species name of a junior homonym has to be replaced, and so we propose Chloritis khammouanensis Inkhavilay & Panha, nomen novum as the new replacement name.
