Dorsal view
Lateral view
Another Sclethrus pair, looks a bit different. Possibly S. malayanus?

Ok, description fits S. amoenius, but it is S. malayanus  |

Please see the map in Han and Niisato's paper. S. amoenus is known from only western India.
From the map, it appears that the ranges of all of the species DO NOT overlap. Yet, what I would expect to find, is that everywhere the ranges of two species meet, is that you would find intermediate forms (possibly hybrids). |

In the key by HAN & NIISATO, 2009, I read :
Body distinctly glossy; antennae very short, barely attaining mid coxae; pronotum almost 2/5 the length of elytra, with two pairs ofbluish-white spots; elytra 3.3 times as long as the humeral width; legs bicolored light brown and black ... S. amoenus
Antennae with spines at each apex of segments 3 and 4, male anal ventrite distinctly concave on apical margin ... S. malayanus
In the genus description, they wrote that S. amoenus has a simple spine on antennae. (but they do not use this character in the key !?)
Nicky's specimens have short antennae, but I am unable to detect 1 or 2 spines on pictures. So, I can't say more.

Could you see the paper again?
I think this is Sclethrus malayanus Han & Niisato, 2009. |

With HAN & NIISATO, 2009. Clytine Beetles of the Genus Sclethrus Newman. Special Bulletin of the Japanese Society of Coleopterology, Tokyo (7): 237-279, I think it is Sclethrus amoenus (Gory, 1833). |
