Head black with a median groove and three spines; the hind pair very long testaceous, decumbent, apressede to head along inner margin of eyes; a single frontal spine very short, testaceous, directed forward.

Antennae very long, slender, testaceous, with the apical joint black and pilose; segment I extremely long, II very short, III very long, slender, more than three and one-halftimes as long as IV, I two times as long as IV, the latter black with the basal portion pale.

Legs very long, slender; tarsi black.

Length, 3.75 mm; width, 0.85 mm.

Holotype (male) and allotype (female) and paratype, Rio de Janeiro, August 10, 1937, collected on Ficus sp. , by Dr. HugO SOuZA LOPES. This material is in the private collection of the author.

Differs from Tigava seibae Drake & Poor , by the much narrower costal area (formed by areolae smaller); the lateral carinae are much less distinct; paranota narrower. Other characters and markings very similar to T. seibae . Most closely allied to Tigava convexicollis Champion , from Panamá, but much smaller.
