Indoplanorbis exustus (Deshayes, 1834) Figure 3E

Material examined.

BOR/MOL6716, BOR/MOL8681.

Distribution and habitat.

Collected from rivers in Tawau and Tuaran.

Remarks.

Indoplanorbis exustus has a wide distribution across Asia and is an intermediate host of zoonotic parasites (Liu et al., 2010). In Peninsular Malaysia, the species has been shown to host Schistosoma spindale, that causes cercarial dermatitis in infected humans (Chiew et al. 2009). The snail was not recorded from Tuaran in the 1970's (Lim et al. 1976), and both lots in BORNEENSIS were only collected in 2016.
