Differs from all other genera of Brachyiulini by lacking ocelli and by having a rather simple, apically incised promerite devoid of any filamentous processes or apical appendages, and a simple unipartite posterior gonopod with a proximal lobe laterally and a subbasal fold and a groove mesally, the latter ending in a subapical opening.

The name combines the type locality, Titanospilia (the cave of Titans) and the suffix – phyllum – referring to the simple, leaf-shaped posterior gonopods. Gender neuter.
