All are around 12 mm.
First two from southern Guizhou, Wangmo county (close to Guangxi), the third one from Xishui county of upper Guizhou (next to Chongqing).
Based on Gressitt & Rondon (1970), the first two are R. laosica, and the third is R. horsfieldii?
Their characters, stripes on pronotum and elytra, seem in the middle of the two species.
The last one makes things complicated. It is from Leishan county, southeastern of Guizhou.
Probably, they are variations of R. laosica? |

Hello,
213.58 KB
I think your first three specimens are Rhaphuma laosica Gressitt & Rondon, 1970: pronotum with S-shaped curved lines (only wavy in R. horsfieldii); longitudinal lines of elytra wavy (longer and straighter in R. horsfieldii); ...
Your fourth specimen is Rhaphuma circumscripta (Schwarzer, 1925).

Thank you for clearance. I was considering Rhaphuma circumscripta for the fourth too but hesitated.

the last one may be Rhaphuma obscurata Pesarini & Sabbadini, 2015 but it is still similar to Rhaphuma laosica.
Their stripes are varied for me.
Rhaphuma circumscripta is different in Taiwan. |

Great! Now I see it more like Rhaphuma obscurata Pesarini & Sabbadini, 2015, as Ivan said.
