Syneches flavithorax View in CoL sp. nov.
( Figs. 36–38 View Figs , 48 View Figs )
Diagnosis. Antenna, proboscis, palpus and scutum yellow; pleura yellow with ventral margin of anepisternum, ventral half of katepisternum and meron pale brown. Legs long and slender, yellow except apex of hind femur black; mid tibia with 1 long AD seta. Wing with colorless stigma.Hypandrium elongate; distal margin with a deep medial concavity forming two lobes bearing long setae, apical seta longest.
Description. Holotype male (UTPL) ( Fig. 48 View Figs ). Body 4.0 mm; wing 3.8 mm. Head. Eyes with lower facets slightly enlarged near subcranial cavity. Eyes yellow on upper part and pale brown on lower part. Ocelli yellow. Ocellar triangle very protuberant, as high as twice the diameter of ocellus; ocellar setae short and slender. Face brown with brown pruinescence. Antenna yellow with short yellow microtrichiae; pedicel with short, brown marginal setae; postpedicel small, as long as length of scape and pedicel combined, rounded, 1.5 times longer than wide, with 1 dorsomedial brown seta as long as postpedicel; stylus about 4.5 times length of antenna, with short microtrichiae, bare on distal fourth. Postcranium dark brown with ferruginous pruinescence, setae brown; postocular setae short, straight and sparse; occipital setae sparse, moderately long, about twice length of postocular setae. Proboscis and palpus brown; palpus short, third length of proboscis, microtrichiae yellow, 1 apical and 1 long ventral medial setae. Thorax. Prosternum narrow. Pronotum yellow with short brown marginal setae. Scutum yellow, strongly arched, pyramidal, postalar callus whitish; golden pruinescence anteriorly and whitish pruinescence on prescutellar disc; scutellum yellow with yellow pruinescence. Setae short, sparse and brown (setae of prescutellar disc lost); acr setae 4-serial; dc setae uniserial; 2 robust npl setae, widely separated, the posterior longer; 1 pal seta. Scutellum with 1 subapical pair of long and robust setae; apical pair slender, half-length of subapical pair; and 3 weak lateral setae, about two-thirds of subapical pair. Pleura yellow, except for lower half of meron and katepisternum, and ventral margin of anepisternum pale brown; pruinescence yellow. Legs long and slender, yellow except apex of hind femur black. Coating setulae short, sparse, pale brown; outstanding setae sparse. Mid tibia with 1 long sub-basal AD seta reaching apex of tibia, and 1 moderately long apical V seta, surpassing mid-length of tarsomere 1. Hind tibia with 1D seta before middle and 1P preapical, moderately long seta. Hind femur with 1AV seta anterior to mid-length and 1AV seta on distal fourth, moderately long and only slightly thickened. Wing. Subhyaline, stigma colorless; apex of R 2+3 nearly straight. Abdomen about 2.5 times longer than thorax; brown with golden pruinescence. Setae brown, sparse, elongate, stouter on latero-distal margin of tergites. Terminalia ( Figs. 36–38 View Figs ) robust. Hypandrium elongate; distal margin with a deep medial concavity forming two lobes bearing long setae, apical seta longest. Epandrial lamella wide; with one long and stouter preapical seta. Phallus robust with sharpened apex and two elongate lateral protuberances. Postgonite broad, as long as phallus.
Female. Unknown.
Type material. Holotype male (UTPL). ECUADOR. Zamora Chinchipe: San Francisco, Reserva Biológica San Francisco, trail Canal , 2000 m, 03 ◦ 58 Ɩ 30 ƖƖ S 79 ◦ 04 Ɩ 25 ƖƖ W, 13/02/2009 – 3/03/2009 (MT), leg. Marc Pollet & Anja De Braekeleer , EC /2009-36/MP&ADB-017. Condition: good, abdomen dissected.
Geographical distribution. Ecuador (Zamora Chinchipe).
Etymology. From the Latin flavus = yellow, in reference to the coloration of thorax.
Comments. This species is similar to S. moraballi Smith, 1963 by having prescutellar disc covered by dense whitish pruinescence, legs slender and yellow, and wing hyaline with colorless stigma. S. flavithorax sp. nov. has yellow thorax, apex of hind femur black and hind tibia lacking median ring, while in S. moraballi , the thorax is light brown, the hind femur is entirely yellow and the hind tibia has a median brown ring.
