Concur here. Cephrenes do not have a male brand.
This one seem to show a mixture of features.
It is probably T. besta but could be T. bambusae species said to be common further north in SE Asia & India.
Salient points.
1 The male brand is centrally placed in the black space.
2. There is a prominent orange triangular patch at the base of space 2.
3. The underside have no noticeable veins darkening.
4. Stated to be much smaller than the others (T besta) in the batch.

T. bambusas horisha Taiwan male.
Note the triangular orange patch at the base of space 2 is well-formed, very similar to T. besta.

Small size & the centrally placed brand in the black space suggest T. bambusae but may just be a T. besta variant if the rest can be reliably IDed as T. besta...
