( Figs 1A–F View Figure 1 , 6A View Figure 6 )
Diagnosis: This species has a thorax with lateral white pruinosity, whereas the dorsal region has light brown pruinosity. It also has two anteroventral apical setae on the hind tibia.
Description: Male. Length: body: 2.9–3.1 mm; wing: 3.0 mm.
Color: General color brown, post-pronotum yellowish. Face and parafacial velvety dark brown with coppery reflections under certain light conditions. Frons, fronto-orbital plate and gena gray pollinose. Antenna brown, the apex of the pedicellum lighter. Arista and palpus brown. Calypteres uniformly whitish. Halter yellow. Wing smoky. Mesonotum brown, all pleurae brown-gray pollinose. Legs yellow, except apices of mid-and hind femora, which are brown. Abdomen dark brown, a little shiny, without clouds; tergite 1 + 2 yellowish at base.
Head: Eyes bare; inner and outer vertical setae long. Frontal row with three pairs of long setae, upper one backward directed. Ocellar setae long, forward-directed, and divergent from one another. Postpedicel about 3.0 times the length of the pedicel. Arista very short pubescent.
Thorax: Acrostichal hairs very fine, pre-scutellar pair not developed. Presutural one; supra-alar one; post supra-alar one. Scutellum with a very long pair of basal setae and a very short and fine apical one. Anepisternum with ground cilia setulae and four long setae, inferior one longer. Fore femur with anterodorsal and anteroventral complete rows of setae. Fore tibia on the posterior surface with one long median seta; dorsal and ventral surfaces with apical setae.Mid femur with three anterior setae, each one inserted in each third of the femur; ventral surface with two fine setae on the basal third and one on the apical third; posterior surface with two preapical setae. Mid tibia with one median anterodorsal and one median posteroventral setae; one dorsal and one ventral preapical and one dorsal apical. Hind femur with about 5–6 anterodorsal spaced setae and two anteroventrals on apical third. Hind tibia with one median anterodorsal and one median posterodorsal setae, one dorsal preapical, one posterodorsal on the apical third, two fine ventrals on the apical third, and one ventral apical.
Abdomen: Tergite 3 with one pair of lateral setae; tergite 4 with two pairs of lateral setae; tergite 5 with a series of four setae on disc. Sternite 5 triangular with many apical setae ( Fig. 1A View Figure 1 ). Sternite 7 and syntergosternite 7 + 8 as in Fig. 1D View Figure 1 .
Terminalia : Cercus is longer than wide and shorter than the surstylus length ( Fig. 1B View Figure 1 ). Surstylus is long and enlarged ( Figs 1B, C View Figure 1 ). Hypandrium tubular and long; phallapodeme with the same diameter in all extensions ( Fig. 1C View Figure 1 ). The pregonite and postgonite are similar in length ( Fig. 1C View Figure 1 ).
Female: Similar to male, except for the absence of the median posterodorsal seta on the hind tibia.Only one anteroventral seta on the hind tibia. Ovipositor long; tergites and sternites narrow, sternites with setae at apex; epiproct shorter than hypoproct; cerci long, with long seta on external margins ( Figs 1E, F View Figure 1 ). Two spermatheca rounded ( Fig. 1E View Figure 1 ).
Material examined: Holotype male: ECUADOR:13171.( EC) Zamora Chinchipe: Bomboscaro, Podocarpus National Park, Trail Higuerones , 1000m, 15/02/2009 - 4/03/2009 ( MT). Leg.Marc Pollet & Anja De Braekeleer , sorted by Marc Pollet – sample code EC/2009-38/ MP & ADB-013 ( UTPL).
Paratypes: Same label as holotype, including the number and sample code: 1♂ 2♀♀ ( UTPL) , 1♂ ( RBINS) , 3♂♂ ( DZUP) , 2♂♂ ( MNRJ) .
Etymology: The specific name refers to the contrasting colors of the upper and lateral sides of the scutum.
