Type species. Micospina auribohnorum gen. et sp. nov.

Diagnosis. Small-bodied Calamyzinae , length <4 mm; mature individuals with 16–24 segments. Lateral antennae slightly longer to twice the length of the palps. Postchaetal neuropodial lobe present; slender neurochaetal joint.

Similar body shape, coloration, and possession of neuropodial postchaetal lobe is also observed in Boudemos gen. nov. Slender neurochaetal joints are also seen in Vigtorniella ( Table 2).

Etymology. Micospina is a Latin compound name describing ‘gleaming spines’, and refers to the shining notochaetae that adorn the type species. Gender feminine.
