Chaetoblaste gonzalezi n. sp.

Diagnosis. As in generic diagnosis plus the following: hypandrium symmetrical; ninth sternite broadly trapeziform, limited on each side by a sclerotized band that extend towards the posterior border of the sternite. Parameres joined by a basal membrane, each arm dilated distally. Epiproct triangular, slightly covered by the clunium. Paraprocts elongate, bearing a distal bilobed projection.

Male. Color (in 70% ethanol). Body reddish brown. Compound eyes black, ocelli hyaline, with thick ochre centripetal crescents. Antennae brown, Mx1–4 pale brown. Legs reddish brown, with apices of femora and t1–t2 more pigmented. Fore- and hind- wings opaque, with a reddish brown hue; pterostigma reddish brown.

Morphology. As in diagnosis, plus the following: compound eyes slightly exceeding the level of the vertex; lateral arms of epicranial suture absent ( Fig. 1 ); antennae slightly thickened. Forewing bearing setae on veins, longer and thicker proximally ( Fig. 3 ). Hindwing glabrous ( Fig. 4 ). Clunial shelf slightly overlapping the epiproct ( Fig. 2 ). Paraprocts elongate; sensory fields with 29–31 trichobothria ( Fig. 2 ). Hypandrium with a sclerotized bulb mesally on each side of the eighth sternum ( Fig. 6 ). Parameres bearing a short distal spine on outer border ( Fig. 5 ).

Measurements (in mm). FW: 3.35, HW: 2.7, F: 1.52, T: 3.37, t1: 0.85, t2: 0.2, ctt1: 16, Mx4: 0.14, f1: 0.71, f2: 0.65, f3: 0.56, IO: 0.46, D: 0.24, d: 0.22, IO/d: 1.97, PO: 0.916.

Specimen studied. Holotype male. COLOMBIA. Valle del Cauca, Santiago de Cali, Km 18, road to the sea, beating dead fern fronds on roadside. 25.VI.2010. MUSENUV, slide code 26677. A. N. García Aldrete.

Etymology. The specific name honors the Colombian entomologist Ranulfo González Obando, of the Universidad del Valle, Santiago de Cali, Colombia, for his enthusiasm and energetic efforts to collect Colombian psocids, and for his significant contributions to the knowledge of Colombian psocids.

Remarks. Right forewing anomalous in having a crossvein between R2+3-R4+5, and in having M3 distally branched; left forewing venation normal.
