Material examined COLOMBIA, Departamento Nariño, Génova, Quebrada El Bohio, 1729 m, 17 April 2013, leg. V. Paz & C. Martínez, 1 apt ♀ (PSO-CZ).

Apterous male. BL 2.76, HL 1.20, HW 0.74; ANT I–IV: 0.42, 0.42, 0.64, 0.64; INT 0.40, EYE 0.20, PL 0.66, PW 0.98. FORELEG: FEM 0.84, TIB 0.80, TAR I–III: 0.02, 0.12, 0.24; MIDLEG: FEM 1.08, TIB 1.04, TAR I– III: 0.02, 0.20, 0.34; HINDLEG; FEM 1.24, TIB 1.54, TAR I–III: 0.02, 0.28, 0.38.

Colour and pilosty. General coloration yellowish brown; pronotum with anterior lobe bearing anterior transverse yellow band, posterior lobe with central area yellow; connexiva yellow; antennae, rostrum (I–III segments), all legs yellow. Venter yellow; laterosternites with black spots. Body covered on dorsum and sides by short, yellow setae, these more numerous on abdomen.

Antennomeres cylindical, IV fusiform; I thicker than others, curved outward. Rostrum slightly passing middle of mesosternum; length of articles III> IV> I> II. Dorsal surface of head foveate ( Fig. 1 ).

Pronotum divided into anterior and posterior lobes ( Fig. 2); anterior lobe separated from posterior lobe by a transverse row of foveae, lacking a median carina. Pronotal and propleural surfaces covered with numerous foveae ( Fig. 1 ). Thoracic sternites lacking tubercles; posterior margins of prosternum, mesosternum, and margins of the first abdominal sternum bearing sinuous, shiny, black sulci ( Fig. 3).

Abdomen with lateral margins rounded, wider on segment V. Connexiva slightly elevated at an angle of 10º, posterolateral angles of tergite VIII lacking acute projections. Posterior margin of the abdominal sternite VII bearing prominent semi-triangular process ( Fig. 4 ) projecting downward ( Fig. 5 ). Parameres symmetrical ( Fig. 6).

Legs with all trochanters unarmed; fore tibia weakly expanded with grasping comb evident on apical onefourth ( Fig. 7); fore femur with apical ¾ bearing a short spine ( Fig. 8); middle tibia with short, semi-recumbent pale setae on distal half of the posterior margin; hind femur slender, bearing a ventral row of four small spines ( Fig. 9).

Apterous female. BL 3.28, HL 1.08, HW 0.80; ANT I–IV: 0.36, 0.38, 0.48, 0.52; INT 0.40, EYE 0.20, PL 0.64, PW 1.24. FORELEG: FEM 0.72, TIB 0.74, TAR I–III: 0.02, 0.10, 0.26; MIDLEG: FEM 1.02, TIB 1.00, TAR I–III: 0.02, 0.22, 0.30; HINDLEG; FEM 1.14, TIB 1.54, TAR I–III: 0.02, 0.28, 0.34.

Body wider and abdomen more rounded; legs lacking spines, fore tibial grasping comb absent. Abdominal tergite VIII widened and flattened and bearing long, erect, brown setae along lateral and posterior margins ( Fig. 10 ).

Comparative notes. Paravelia fanera sp. n. is similar in appearance and shape of the pronotum to P. capixaba Moreira, Nessimian & Rúdio, 2010 but differs on the basis of several characters. Specimens of P. fanera can be diagnosed by the foveae on the pronotum and the propleurae ( Figs. 1 , 2), and posterior margins of the prosternum and mesosternum bearing sinuous, shiny, black sulci ( Fig. 3). The male hind femur also bears four spines on ventral apical half ( Fig. 9); abdominal sternite VII of male bears a semitriangular midle-ventral prolongation ( Figs. 4 , 5 ); and the male paramere is diagnostic ( Fig. 6). In addition, the lateral and posterior margins of the abdominal tergite VIII in the female are covered with long setae ( Fig. 10 ).
