Materials examined.

Malaysia • Penang Hill, Moniot trail, Plot. 32 ; 5.4165 ° N, 100.2574 ° E; 695 m a. s. l.; 4 Feb. 2023; T. S. Liew, A. Yusni leg.; BOR/MOL 15747 GoogleMaps .

Remarks.

New record for Penang Hill. So far, only one Ditropopsis species has been recorded from Peninsular Malaysia ( Maassen 2001), namely Ditropopsis cavernae ( Sykes, 1903) , which is distinctly different from the species found on Penang Hill. This genus was not recorded in previous systematic inventory studies in Peninsular Malaysia ( Liew 2010; Foon et al. 2017; Foon and Marzuki 2023). The species from Penang Hill is similar to Ditropopsis constricta Vermeulen, Liew & Schilthuizen, 2015 in terms of size, shape, and shell sculpture but differs by having a detached protoconch.
