Chloritis penangensis: Foon et al. 2017: 56-57, fig. 21D.

Type specimens.

The types should be in the Zoological Survey of India in Kolkata but were not found during a recent search (S.K. Sajan, pers. comm., December 2018). They were likewise not found in the NHM.

Type locality.

“Penang” .

Remarks.

" Chloritis penangensis has a much more globular shell with less expanded whorls compared to Chloritis breviseta which has more expanded (perpendicular to the axis) whorls and thus, “wider” looking shells. These characters appear consistent for each species across Peninsular Malaysia (based on conchological comparisons), although shell size varies within each species." (Junn Kitt Foon, pers. comm., 01 Dec 2018). To illustrate these differences, we illustrated the shells of both species (Figs 10, 11).
