Diagnosis . Belonging in the Graphocaeciliini . Ocelli absent. Forewing veins with a row of conspicuous setae, except on Cu2. Hypandrium with sides and posterior border distinctly thickened. Endophallus large, formed by a compact group of small sclerites. Aedeagal arch projected posteriorly in the middle. External parameres broad, with a slender, distal projection. Posterior border of clunium, over the area of the epiproct, with a broad, elongate, curved, spatulate posterior projection that covers most of the epiproct. Male paraprocts with a distinct, elongate sclerotized anterior projection, joined to clunium. Female subgenital plate with a median concavity posteriorly; gonapophyses joined to clunium, V1 absent, and V 2 +3 elongate, joined to clunium, distally pointed, with a row of macrosetae along outer border. Etymology. The generic name is a compound word formed with Dagua, the municipality where the two species of this genus were found, and Lachesilla . Type species. Dagualachesilla anchicayaensis n. sp. Dagualachesilla anchicayaensis n. sp. ( Figs 1 , 4–16 ) Diagnosis. Male with distal end of abdomen bulbous ( Figs 1 , 8 ); hypandrium setose, rounded posteriorly, broad, with sides and posterior border distinctly thickened ( Fig. 7 ). Phallosome broadly triangular ( Figs 10, 11 ). Posterior border of clunium, over the area of the epiproct, extended posteriorly to form an elongate, curved, spatulate projection, wider distally, with posterior border almost straight ( Fig. 12 ). Aedeagal arch attached below and laterally to external parameres, with a stout, blunt ended, slightly knobbed on sides, posterior projection ( Figs 10, 11 ). Female subgenital plate broad, densely setose, with a median concavity in the middle of posterior border ( Fig. 16 ); IX sternum thick, pigmented, almost rectangular; gonapophyses elongate, narrowing distally, with a membranous area of small spicules near the inner border of the distal third, with long setae along outer border ( Fig. 15 ). Male . Color (in 80% ethyl alcohol). Tawny brown, compound eyes black, legs pale brown, forewings darker than the hindwings. Tergal lobes of meso- and metathorax brown, abdomen creamy, with brown, transverse subcuticular rings, little pigmented ventrally ( Fig. 1 ). Clunial projection brown, setose; epiproct and paraprocts pale brown. FIGURES 1–3. Males of Dagualachesilla and Dagualachesilloides species, lateral view. 1. Dagualachesilla anchicayaensis n. sp. 2.

Forewing pterostigma elongate, narrow anteriorly, much wider posteriorly, lp/wp: 2.70, with setae scattered in the membrane, mostly near the costal margin. Areola postica almost triangular ( Fig. 4 ). Hindwing L/W: 2.89 ( Fig. 5 ). Endophallus with sides deeply concave, slightly concave anteriorly, almost straight posteriorly. Paraprocts ( Fig. 9 ), broad posteriorly, setae restricted to the mid lateral and posterior areas, with a field of small spicules posteriorly, next to the posterior macrosetae; sensory fields with 16 trichobothria in basal rosettes. Epiproct ( Fig. 12 ), elongate, posteriorly rounded, with fields of setae mesally and along posterior border. FIGURES 13–19 . Dagualachesilla spp. Females. 13–16. D. anchicayaensis n. sp. 13.
