Barbaropus flatus sp. nov.

( Figs 1–16 )

Type materials. Holotype. 6 ( USNM) Ecuador: Orellana, Transect Ent. 1km S. Onkone Gare Camp, Reserva Etnica Waorani 00 0 39'10"S 076 0 26'00"W, 3 July 1999, coll. T. L. Erwin LOT #1093, station 4-3 . Paratypes. 266 ( INHS, NWAFU), same data as holotype .

Description: Body length: male 2.8–2.9 mm.

Ground color (specimens previously stored in ethanol) whitish except forewing with red transverse preapical marking, crown and face white to pale orange color with very indistinct orange markings ( Figs 1–4 ). Eyes dark ( Figs 1–4 ). Pronotum with round dark area medially ( Figs 1, 3 ). Mesonotum with pair of oval bright whitish spots on each side ( Figs 1, 3 ). Forewing mottled with red spots, venation poorly delimited, and hind wing subhyaline ( Figs 1, 2, 8, 9 ). Legs white to pale orange except pretarsus and hind tibia apically dark ( Figs 1, 2 ).

Male basal abdominal sternal apodemes not developed; 4S apodemes vestigial; 5S apodemes absent ( Fig. 7 ). Pygofer with basal ridge of ventral process straight through most of length, free distal part of process extended posterodorsad, spinelike, apex not reaching posterior margin of lobe ( Figs 5 , 10 ). Subgenital plate almost parallel-sided through most of length in lateral and ventral views, apex obliquely truncate; A-group setae (3) much longer than B-group setae; B-group setae (8–10) small, and stout, in compact group at middle of dorsolateral margin; C-group with two setae, not reaching apex of plate ( Figs 5 , 10, 13 ). Paramere extending to apex of plate, apex curved laterad, outer margin with 4–5 setae, without tiny teeth ( Figs 5 , 10, 14 ). Connective with stem wide, with slight dorsoapical keel; arms narrow, widely divergent, subequal to stem in length ( Figs 6 , 15 ). Aedeagus with unpaired ventral process slender, extended ventrad, apex curved posterad and acuminate; lateral processes widely divergent from shaft, shorter than ventral process, with granulose microsculpture; dorsal apodeme tapered dorsally in lateral and posterior views; shaft compressed, slender, unevenly and slightly curved dorsad in lateral view, denticuli sparse on distal two thirds, gonopore subapical on ventral surface ( Figs 5, 6 , 10–12 ). Anal tube process straight, tapered toward apex, bifid apically with dorsal branch slightly shorter than ventral branch, both of them smooth ( Figs 5 , 10, 16 ).

Etymology. The genetic name, a masculine noun, is derived from Latin words " flat ", alluding to shape of caudal margin of connective.

Distribution. Ecuador. Habitat. The type series was collected by insecticidal fogging of a primary lowland terra firme rainforest canopy column 30–35m tall with mostly bare green leaves, some with covering of lichenous or bryophytic plants.
