Holotype male, mounted on slides; thorax in a separate microvial. Original label: Ecuador. Napo. Reserva Étnica Waorani, 1 Km S. Onkone Gare Camp. 220m. 12.II.1995. 0°30'10"S: 76°26'0"W. Fogging terre firma forest. T. L. Erwin et al. Paratype: 1 male, same data as the holotype (EPN, slides 163-164, vials 163-164).


This species is dedicated to Dr. Terry L. Erwin, of the Smithsonian Institution, Washington, D. C., USA., in recognition to his seminal studies in biodiversity, in estimating the number of arthropods on this planet, in systematics and biology of the Carabidae , and for making available for study to ANGA, the psocid specimens collected by his team in Napo, Ecuador, by canopy fogging.


Differing from the known species of Triplocania , in having the hypandrium with side sclerites and central piece similar in size; central piece with two short, lateral posterior projections, and two short, blunt ended, median posterior projections, leaving between them a small concavity, in having the external parameres with a distinct lobe apically on the inner side and, in having two pairs of endophallic sclerites.


Color. Body pale brown, with ochre spots as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 8). Scape brown and pedicel yellow, f1-f3 yellow, with apices white. Mx4 brown. Tergal lobes of meso and methathorax brown, pleura with ochre spots above the level of the coxae; dark brown bands on proximal and distal ends of coxae, femora yellow with three brown equidistant bands, a middle one, and one on each end of the femur; tibiae pale brown, tarsomeres 1-3 yellow. Forewing with an irregular, submarginal brown band from R2+3 to areola postica, this with a small brown spot proximally, and a dark brown spot between its apex and M, a dark brown spot below the proximal end of CuA, and a brown spot at confluence of CuP– 1A; a pale brown spot between proximal ends of R4+5-M1; pterostigma with brown bands anteriorly and posteriorly; veins brown, with brown spots at wing margin (Fig. 9). Hindwing almost hyaline, veins brown, with a pale brown spot at confluence of CuP and wing margin (Fig. 10).


As in diagnosis plus the following: compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with five denticles (Fig. 11). Fore wing pterostigma basally narrow, wider in the middle; areola postica wide basally, slightly slanted posteriorly; R2+3 and R4+5 sinuous, M stem slightly concave proximally, M1, M2 and M3 sinuous. Hindwing Rs almost straight, R2+3 and R4+5 straight, M sinuous. Hypandrium with two large setae posteriorly between each lateral-median posterior projections (Fig. 12). Phallosome with side struts independent, V shaped, fused posteriorly to external parameres, these stout, with pores posteriorly; the distal lobe of each heavily sclerotized; anterior pair of endophallic sclerites elongate, almost touching anteriorly, inserted on a membranous, V shaped, thickened area, lying distally behind the external parameres, ending in a rounded apex; posterior pair of endophallic sclerites triangular, each anteriorly concave, close to the inner border of the external parameres, with apices sinuous.
