Limnophora equatoriensis sp. nov. ( Figs. 13–18 )

Diagnosis. This species is easily differentiated by the dorsocentral setae 2 + 3, vein R 1 bare on both surfaces and R 4+5 with setulae near of base of radial sector on dorsal surface.

Description. Male. Measurements (n = 5): Length: Body: 6.0– 6.4 mm (6.0 mm), Wing: 5.6–6.4 mm (6.24 mm).

Color: Face silver pollinose. Antenna dark brown with silver pollinose; arista dark brown. Palpus dark brown. Calypters uniformly whitish with border dark brown more conspicuous at lower. Halter yellowish. Wing hyaline yellowish with conspicuous dark brown cloudy spots from costal margin to apex of vein R 2+3. Presutural scutum and scutum dark brown; humeral callus and notopleura gray pollinose; scutum dark brown, without vittae, with 2 silver spots near scutellum; scutellum dark brown. Pleurae dark brown with katepisternum mostly gray pollinose. Legs dark brown. Abdomen with median longitudinal silver vittae and dark brown with silver lateral round areas on all tergites.

Head: Holoptic, distance between eyes 0.04–0.06 (0.04) times head width; eyes finely and sparsely ciliated. Inner and outer vertical setae shorter than ocellar setae. Frontal seta with 6–8 (6) pairs; 1 proclinate orbital seta near ocellar triangle. Ocellar setae long; ocellar triangle with tuft of short hairs. Antenna not reaching epistoma; flagellomere I about 2.0–3.7 (2.5) times pedicel length, ending before insertion of vibrissa. Hairs on arista shorter than diameter of arista at base. Parafacial and fronto-orbital plate bare. Palpus filiform.

Thorax: Chaetotaxy. Acrostichals 0 + 1; dorsocentrals 2 + 3; intra-alars 2 + 1; supra-alars 2; basal postpronotals 2; notopleurals 2; postsupra-alars 2. Scutellum with well developed lateral, apical scutellar setae. Anepisternum with 6–7 (6) long setae; katepisternal seta 1 + 2. Prosternum setulose.

Legs. Fore femur with complete rows of posterodorsal and posteroventral setae; fore tibia with 2 apical setae (dorsal and anteroventral). Mid femur on ventral surface with 4 strong setae on basal half, posterior surface with 2 pre-apical setae; mid tibia with 1 median setae on posterior surface and 3 apical setae (anteroventral, ventral and posteroventral). Hind femur with complete row of setae on anterodorsal and anteroventral surfaces with 3–5 (3) setae on apical half; hind tibia with 2 median setae on anterodorsal and anteroventral surfaces; 2 apical setae (ventral and anterodorsal).

Wing. Vein R 1 bare on both surfaces; Rs node and base of vein R 4+5 setulose dorsally and ventrally; vein dm-cu straight; apical portion of vein M bent toward vein R 4+5.

Abdomen. Tergite III with row of setae on margin; tergite IV with 1 pair median marginal seta; tergite V with row of setae on margin and 1 pair of median marginal seta. Sternite 1 bare; sternite 5 trapezoid, longer than wide, with many and sparse setae and two apically developed ( Fig. 13 ).

Terminalia. Cercal plate longer than wide, with submedian fusion and long setae on inner apex; surstylus greater than cercal plate length ( Fig. 14 ). Distiphallus median, about 1.5 times the length of pregonite; postgonite slightly curved and shorter than epiphallus ( Fig. 15 ).

Female. Length: Body: 6.6–7.2 mm, Wing 6–6.6 mm. Similar to male, but dichoptic, distance between eyes 0.30–0.42 times head width. 4 frontal setae; 2 fronto-orbital setae, anterior reclinate; inner vertical setae convergent; outer vertical setae divergent. Fronto-orbital plate with few setulae. Abdomen with 1 pair of discal setae on tergite V.
