description: Limnophora longivittata sp. nov.  (Figs. 31–36)   
 Diagnosis. This species is easily differentiated by the dorsocentral setae 2 + 3. Vein R 1 with conspicuous setulae on apex dorsal surface. Prescutum dark brown with 2 conspicuous white vittae extending over scutellum.   
 Description. Male. Measurements (n = 3): Length: Body: 6.0– 6.16 mm (6.16 mm). Wing: 5.36–5.6 mm (5.52 mm).   
 Color. Face gray pollinose. Antenna and arista dark brown. Palpus dark brown. Calypters uniformly whitish. Halter brownish with knob yellowish. Wing hyaline yellowish with conspicuous brown cloudy spots from costal margin to apex of vein R 2+3. Prescutum dark brown with 2 conspicuous white vittae extending over scutellum; humeral callus and notopleura gray pollinose; scutum dark brown; 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 0.06–0.08 (0.07) times head width; eye finely and sparsely ciliated. Inner and outer vertical setae long same length than ocellar seta. Frontal seta with 6–7 (7) pairs of setae; 1 proclinate orbital seta near triangle ocellar. Ocellar setae long; ocellar triangle a tuft of hairs. Flagellomere I about 1.7–1.8 (1.7) times pedicel length, ending before insertion of vibrissa. Arista with hairs shorter than diameter of the arista at base. Parafacial and fronto-orbital plate bare. Palpus filiform slightly dilated apically.  
Thorax. Chaetotaxy. Acrostichals 0 + 1; dorsocentrals 2 + 3, all developed and same length; intra-alars 2 + 2; supra-alars 2; basal postpronotals 2; notopleurals 2; postsupra-alars 2. Scutellum with well developed lateral, apical scutellar. Anepisternum with 5–6 (5) long setae; katepisternal seta 1 + 2. Prosternum setulose.  
Legs. Fore femur with complete rows of posterodorsal and posteroventral surfaces; fore tibia with 2 apical setae (dorsal and posteroventral). Mid femur on ventral surface with 4–7 stronger setae on basal half and posterior surface with 2 pre-apical setae; mid tibia with 1 supra-median and sub-median setae on posterior surface; 3 apical setae (ventral, anteroventral and posteroventral). Hind femur with complete row of setae on anterodorsal and anteroventral surfaces with 4–6 (6) setae on apical half; ventral surface with 5 setae on basal half; hind tibia with 1 median seta on anterodorsal and posteroventral surfaces; 3 apical setae (ventral, anterodorsal and anteroventral).  
 Wing. Vein R 1 with conspicuous setulae on apex dorsal surface; Rs node and base of vein R 4+5 setulose dorsally and ventrally; vein dm-cu slightly sinuous; 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 median marginal seta. Sternite 1 bare; sternite 5 triangular, longer than wide, with few and sparse setae and two apically developed (Fig. 31).  
Terminalia. Cercal plate longer than wide, with submedian fusion, with long setae on apical half; surstylus smaller than length of cercal plate (Fig. 32). Distiphallus long, about 2.5 times than length of pregonite; postgonite slightly curved and smaller than epiphallus (Fig. 33).  
 Female. Length: Body: 5.8–6.4 mm. Wing: 5.68–6.24 mm. Similar to male but, dichoptic, distance between eyes 0.38–0.42 times head width. Frontal seta with 5 setae, 2 fronto orbital setae, anterior reclinate; inner vertical setae convergent; outer vertical setae divergent. Fronto-orbital plate with few setulae. Thorax with wide vittae brown and 2 narrow vittae gray.   
 Type material   
 Holotype. Male: “ E. Papallacta \ (Quito Baeza) \ Ecuador. 2900 m. I-1-71 \ L. E. Peña col. [white printed label]”; “ Holotipo [red printed label]” (UTPL). Paratypes. 2 males, 2 females, same data as holotype (UTPL, DZUP).   
 Distribution. ECUADOR: Napo (Quito, E. Papallacta).   
 Etymology. Adjective, agreeing in gender with the feminine Limnophora. The specific epithet refers to the 2 conspicuous white long vittae extending over scutellum (from de Latin longus = long, vitta = stripe).
