Guapinannus policis , sp. n.

( Figs 3 , 7 , 9 )

Holotype. Male. COLOMBIA: Cauca: PNN Gorgona, Antigua Laguna , 2.96667°N 78.18333°W, 70 m, 18 Dec 2000 – 03 Jan 2001, H. Torres, 1♂ ( UCR _ ENT 00109003 ) ( UCR).

Paratype: COLOMBIA: Cauca: PNN Gorgona, Alto el Mirador, 2.96666°N 78.18333°W, 180 m, 06 Oct 2000 – 23 Oct 2000, R . Duque, 1♀ ( UCR _ ENT 00115594 ) ( UCR) .

Etymology: Named for the thumb-shaped basal process of the right paramere after “policis” Latin for thumb.

Diagnosis: Recognized by the small body length (1.03 mm), elongate oval forewing outline, short and wide rc, rc1, and tc (black star) ( Fig. 3 ), slender vesica with acute tip, and thumb-shaped basal process of the right paramere (black arrow) ( Fig. 7 ).

Description: Male: Total body length 1.03 mm; length from posterior margin of pronotum to posterior wing margin ambiguous 0.7 mm; greatest width across pronotum 0.47 mm; greatest width across forewings 0.63 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with sparse setae, setae short; setae on posterior margin of forewing long. Structure: Head: Eye almost half as high as head; muscle scars small. Thorax: Anterior pronotal margin concave, posterior margin slightly concave; pits on pronotum large, evenly distributed; scutellum in dorsal view gradually narrowed to tip, tip pointed. Forewing: With outline broad anteriorly, elongate oval; membrane contributing about one third of forewing length, posterior distal margin squarish, veintracing areoles on proximal part of wing absent; C+Sc broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium inflated, elongate, with median notch; without notch articulating with claval process; rc1 about 3 times as long as wide, much wider anteriorly; rc about 3 times as long as wide; tc about 3 times as long as wide; part of An1 and Cu forming posterodistal margin of tc of similar width as other veins; distal margin of rc1, rc, and tc cells double s-shaped; rc2–3 trapezoidal; cub almost reaching wing margin; dc1 horse headshaped. Legs: Claws long. Genitalia ( Fig. 7 ): Pygophore without lobe on right side; vesica with between half and one loop, not reaching right pygophore margin, relatively slender at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge with process, process short, with single lobe curved, tip pointed; right paramere curved, broad throughout, basal process thumb-shaped; left paramere straight, tapering, basal process narrow.

Female: As in male and generic description.

Collecting method: Collected using a Malaise Trap.
