A bit difficult to identify this insect. As we have discussion with Eehean Yap in the Facebook SG Insect ID and Records
Believe it’s in the “Coptosomatinae” as those tend to have a “pseudoscutellum” (to varying degrees of obviousness) and their heads are usually quite narrow, when compared to the Brachyplatys group of plataspids. But this subfamilial classification of the Plataspidae is very controversial, and may exclude quite a bit of genera and species.
As per now Dec 2020, we put under this Sub Family Coptosomatinae.
Spotted at Upper Seletar Reservoir – Dec 2020
