Syneches polleti View in CoL sp. nov.
( Figs. 39–43 View Figs , 49 View Figs )
Diagnosis. Antenna pale brown to brown. Proboscis and palpus yellow. Thorax brown except postpronotal lobe and postalar callus yellow; scutum highly arched but rounded with reddish brown pruinescence on anterior half and mixed gray and golden pruinescence on prescutellar disc and scutellum, and slender grayish yellow dorsocentral stripe; prosternum narrow. Legs slender with hind tibia swollen toward apex and hind tarsomere 1 enlarged; legs yellow except coxae, trochanters, apex of hind femur, distal three-fourths of fore tibia, hind tarsomere 1, distal portion of hind tarsomeres 2–5 and fore and mid tarsomeres pale brown. Hypandrium elongate; with some long setae on distal half medially; distal margin with shallow medial concavity forming two round lateral lobes.
Description. Holotype male (UTPL) ( Fig. 49 View Figs ). Body 4.7 mm; wing 3.7 mm. Head. Eyes and ocelli yellow. Ocellar triangle slightly protuberant; anterior pair of ocellar setae long and posterior pair very short and thin. Face brown with brown pruinescence. Scape and pedicel pale brown; pedicel bearing elongate brown marginal setae; postpedicel shorter than length of scape and pedicel combined, brown, with 1 short sub-basal dorsal seta, apex truncate; stylus bare, approximately twice length of antenna. Postcranium brown, pruinescence sparse and pale; postocular setae short, almost inconspicuous on upper half of postcranium, brown; occipital setae sparse, longer than postoculars. Proboscis and palpus yellow; palpus with one apical and one long ventral median setae. Thorax. Prosternum narrow. Pronotum with short, pale-brown, marginal setae. Scutum highly arched but rounded; brown with postpronotal lobe and postalar callus yellow; with reddish brown pruinescence on anterior half and mixed gray and golden pruinescence on prescutellar disc and scutellum, a slender grayish yellow dorsocentral stripe and pale pruinescence laterally. Setae short, sparse and brown, longer on prescutellar disc; acr setae multiserial with one discreetly differentiated pair on prescutellar disc; dc setae uniserial, with 1 prescutellar pair long and robust and bent tip; ial sparse; 2 long npl setae; 1 long and slender pal seta. Scutellum setose with 1 long and robust, slightly convergent, subapical pair of setae; 2 slender apical pairs, convergent, about three-fourth the length of subapical pair; and 5 slender lateral setae, as long as apical pair. Pleura brown with pale pruinescence. Legs slen- der; femora not swollen; hind tibia swollen toward apex; hind tarsomere 1 enlarged. Coxae, trochanters, apex of hind femur, distal three-fourths of fore tibia, hind tarsomere 1, distal portion of hind tarsomeres 2–5 and fore and mid tarsomeres pale brown, remaining parts yellow. Setae pale brown. Fore tibia with 3AD setae slightly longer and more robust than all other setae; basal third of mid tibia with 1AD seta and 1PV seta, very long, surpassing, apex of tibia, and 1 long apical P seta reaching apex of tarsomere 1. Hind femur with 4 very long AV setae, 1A seta and 1D short seta on distal fourth, and some elongate PV setae on distal third. Hind tibia with 1 median AD seta and 1 preapical AD seta, with both setae long and robust. Wing yellowish, subhyaline with large quadrate brown stigma at the end of cell r1. Abdomen slen- der, about 3 times length of thorax; brown with reddish brown pruinescence. Setae brown, short dorsally and longer on lateral of tergites. Tergite 8 short; sternite 8 short and trapezoidal, with some setae on distal corners. Terminalia ( Figs. 39–41 View Figs ) robust. Hypandrium elongate; with some long setae on distal half medially; distal margin with shallow medial concavity forming two round lateral lobes. Epandrial lamellae wide, slightly concave apically with small dorsoapical projection and robust preapical setae. Phallus elongate with round apex and two small lateral protuberances. Postgonite broad, slightly longer than phallus.
Female. As in male. Terminalia ( Figs. 42 and 43 View Figs ): T 8 rectangular; St 8 mostly membranous with central portion sclerotized and short setae; cercus very short, ovate, about one-fourth length of segment 10.

Geographical distribution. Ecuador (Zamora Chinchipe).
Etymology. The species is named after Marc Pollet from the Research Institute for Nature and Forest (INBO), Brussels, Belgium, collector of the type-series, in honor of his worldwide contribution to the knowledge of Empidoidea.
Comments. This species is similar to S. manaos Smith, 1962 in having a narrow prosternum, wing with large quadrangular stigma at the end of vein r1 and abdomen slender and elongate. The two species can be distinguished by the protuberant ocellar triangle and slender femora in S. polleti sp.nov. In S. manaos , the ocellar triangle is not protuberant and all femora are swollen, notably the hind femur. Additionally, the features of the male terminalia are dissimilar in both species.
