Etymology. This species is named after Gustav Hermann Krumbiegel the German botanist who designed and planned gardens and avenues in Bengaluru, the type locality of the specimens. The name is treated as a noun in the genitive case.

Diagnosis. B. krumbiegeli sp. n. is closer to B. mareecha sp. n. and B. arachnophagus sp. n. IOS is wider in B. krumbiegeli sp. n. than B. mareecha sp. n. and it is equal to eye length in the former while it is around half the eye length in the latter; upper frons weakly reticulate and gena smooth in B. krumbiegeli sp. n. whereas upper frons is coriaceous reticulate and gena reticulate in B. mareecha sp. n.; scutes are larger in B. krumbiegeli sp. n. than in B. mareecha sp. n. The differences between B. krumbiegeli sp. n. and B. arachnophagus sp. n. are mentioned under the latter.
