Female. Unknown.

Variations. There are no variations.

Differential diagnosis. This species is morphologically similar to C. quelatus by having the harpe with medial-dorsal corner partially arched, the apical margin with large excavation and the apical projection of basivolsella glabrous. However, C. tremembe sp. nov. differs from C. quelatus by having the hypostoma angled medially, the mesopleural epicoxal sulcus absent, the hypopygeal anteromedial apodeme absent, the dorsal harpal margin straight, the cuspis glabrous, the cuspis apex posterior to apex of digitus, the cuspis apex straight and aedeagus with one pair of apical lobes, whereas C. quelatus has the hypostoma curved medially, the mesopleural epicoxal sulcus present, the hypopygeal anteromedial apodeme present, the dorsal harpal margin outcurved, the cuspis setose, the cuspis apex anterior to apex of digitus, the cuspis apex sharp and aedeagus with two pairs of apical lobes.

Etymology. The specific epithet tremembe refers to the indigenous people “Tremembé” from Ceará and Maranhão, Brazil.
