Arenas, Malaise trap [forewing length, 8.0 mm; hindwing length, 6.0 mm] (IAvH-E-115978); Paratypes: Colombia: Caquetá: Puerto Abeja, NNP Chiribiquete, Bosque Coluvial, 310 m, 2~ 12.II.2000, C.

Good, preserved in alcohol.

Diagnosis. This species is separated from other Colombian species by having wing venation almost completely dark brown or piceous in some specimens, and from other species from the Amazon basin by the following male genital characters: ectoproct in lateral view subrectangular; sternite IX in ventral view subtrapezoidal, with apex acuminate and pronounced. Gonocoxites with one long preapical spine.

Description. Based on six specimens, three males and one female pinned and two males and one female preserved in alcohol.

Head. Clypeus and labrum pale or dark brown; frons dark brown, vertex yellow ( Fig. 14 c); brown stripe extending posteriorly from antennal sockets to occiput. Scape and pedicel dark brown, flagellum dark brown with 35 articles, densely covered with thick black setae.

Thorax. Pronotum with long and thick setae arising from protuberant bases in lateral view, with dark brown central stripe in dorsal view, projected laterally at anterior margin ( Fig. 14 e). Pteronotum with sclerites dark brown in the middle, yellow or ochre at the periphery, entire surface with fine and short setae. In some specimens, mesoescutellum, metaprescutum and metascutum, pale yellow. Pteropleura yellow with dark brown spots ( Fig. 14 d).

Legs. Foreleg with coxa brown, covered with yellow setae. Femur predominantly yellow, outer surface medially with diffuse brown spot irregularly shaped, entire surface covered with yellow setae ( Fig. 14 e); inner surface mostly yellow ( Fig. 14 f). Tibia piceous or amber, completely covered with yellow setae; tarsomeres and claws yellow, in some specimens the first tarsomere piceous. Mid- and hindlegs with coxae dark brown, trochanter and femur yellow, tibiae with basal half piceous, distal half yellow; tarsomeres yellow.

Wings. Forewing length, 8‒8.5 mm; membrane hyaline; venation piceous, except by bases of Cu and AA, which can be yellow or pale brown; posterior margin alternating dark brown and yellow ( Fig. 14 a). Costal field with 12 crossveins. Three veins arising from 1RA cell, two or three from 2RA; Rs with eight or nine gradate crossveins. Pterostigma piceous, some specimens with pale yellow spot in the middle, sometimes very small or suffused. Hindwing similar to forewing ( Fig. 14 b), length 6‒6.5 mm; base of M, Cu and A, yellow; costal field with four crossveins; two or three veins arising from cell 1RA, one or three from the 2RA; Rs with six gradate crossveins.

Abdomen. Tergites predominantly dark brown, each with two lateral yellow spots. Sternites predominantly yellow, laterally with dark brown spots. Segments II‒IV with pleural membrane yellow, dark brown in other segments. Segment IX and ectoproct piceous, densely covered with long dark brown setae, in other segments shorter and yellow.

Female. Similar to male, sternite VIII dark brown on the posterior half, yellow on the anterior half. Tergite IX dark brown; gonocoxites pale yellow, basally dark brown, as long as the length of the last three abdominal segments together.

Male genitalia. Ectoproct subrectangular in lateral view ( Fig. 15 b). Sternite IX subtrapezoidal in ventral view, apex acuminate and pronounced, densely covered with long setae ( Fig. 15 c), apex as long as the ectoprocts in lateral view ( Fig. 15 b). Gonocoxites short in lateral view, medially arched with a single long preapical digitiform process ( Figs. 15 b, d), arched in ventral view, medially with apex externally directed, basal- and medially uniformly enlarged ( Fig. 15 a). Gonarcus with the lateral lobes sinuous in lateral view, medial lobe rounded ( Fig. 15 b), U-shaped in ventral view ( Fig. 15 a). Pseudopenis strongly coiled in lateral view with base sinuous, apex protruding from abdomen ( Fig. 15 b).

Distribution. Widely distributed species in the Orinoco- and Amazon basin.

Adult flight period. Individuals of this species have been collected from December to February and June to August.

Etymology. Species named in tribute to aboriginal ethnicity Karijona , traditional ancient people who lived in the territory of the current National Natural Park Serranía de Chiribiquete. The new name is a noun (indeclinable).
