Abdomen. Total length 1.960, not including terminalia. Tufts of at least 50 long bristles emerging from two adjacent dark-pigmented patches on each segment. Terminalia ( Fig. 11 ): aedeagal apodeme simple and narrow, 0.228 long. Gonocoxite length 0.280 and width 0.175, bearing short, pointed projection with approximately 10 bristles on basal 2/3 of structure. Gonostylus ( Fig. 12 ) 0.315 long, approximately same length as gonocoxite, width 0.084. Row of 25–30 stout, semifoliaceous spines on lower surface, extending from the base up to midpoint. Bifurcated tip formed by two stout, downward-pointing processes each bearing stout sclerotized spines. Larger process with four spines emerging from distal tubercle and two more arranged in parallel on inner surface. Smaller process set at right angles to above, with three short spines of different lengths each emerging from separate tubercle. Few fine hairs emerging from tip of bulge overhanging projections. Paramere ( Fig. 10 ) 0.315 long, blade-like with curved ventral projection and small flag-like process on upper edge bearing eight fine hairs. Lateral lobes short, 0.088 long and 0.042 wide. Cercus length equal to that of lateral lobes. Aedeagus half moon-shaped, 0.105.

Type locality. Brazil, Espírito Santo State, municipality of Vargem Alta, Belem (20º 47,093`S 41º 00,472`W; 350 masl) 15.I.2007.

Type material. Holotype male number 0 0 2. Santos C. B. 24.III.2007, deposited in Psychodidae collection of CEUMT-UFES.

Etymology. The specific name derives from “ capixaba ” the vernacular term for a native of the Brazilian State of Espírito Santo.
