Specimen labels

Nothing is known about the biology of Microdaceton tanyspinosum.


Bolton (2000) - In the few specimens of tanyspinosum that are known the dorsum of the postpetiole is densely longitudinally costulate and the bases of both the first gastral tergite and sternite are smooth.

This species falls into the same size range as Microdaceton tibialis and has MI and SI in the same range, but its head averages broader (CI 90 - 95, as opposed to CI 86-92 in tibialis) .
