description: Limnophora polleti sp. nov.  (Figs. 43–48)   
 Diagnosis. This species is easily differentiated by the dorsocentral setae 2 + 4, vein R 1 dorsally setulose on apex, vein R 4+5 dorsally with setulae almost reaching apex, meron and sternite 1 with setulae.   
 Description. Male. Measurements (n = 2): Length: Body: 5.6–6.4 mm (6.4 mm). Wing: 5.68–5.76 mm (5.68 mm).   
 Color. Face silver pollinose. Antenna and arista dark brown. Palpus dark brown. Calypters uniformly whitish with border brownish, lower more conspicuous. Halter brownish with knob yellowish. Wing hyaline brownish with dark brown cloudy spots from costal margin to apex of vein R 2+3. Prescutum dark brown, humeral callus and notopleura gray pollinose, scutum dark brown gray pollinose near scutoscutellar suture; 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 0.02 times head width; eye finely and sparsely ciliated. Inner and outer vertical setae somewhat shorter than ocellar setae. Frontal seta with 6–7 (7) pairs; 1 proclinate orbital seta near ocellar triangle. Ocellar setae long; ocellar triangle a tuft of hairs. Flagellomere I about 2 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 + 4, first and second postsutural seta somewhat shorter than others; intra-alars 2 + 2 the setae postsutural somewhat developed, but distinct; supra-alars 1; basal postpronotals 2; notopleurals 2. postsupra-alars 2. Scutellum with well developed lateral, apical scutellar. Anepisternum with 6 long setae; katepisternal seta 1 + 2. Meron with setulae. Prosternum setulose.   
Legs. Fore femur with complete rows of posterodorsal and posteroventral setae; fore tibia with dorsal, anteroventral apical seta. Mid femur with 2 (1) stronger setae on ventral basal surface; mid tibia with 1 supra-median and sub-median setae on posterior surface and 3 apical setae (anteroventral, ventral and posteroventral). Hind femur with complete row of setae on anterodorsal, anteroventral surface with 3–5 (3) setae on apical half; hind tibia with 2 median seta on anterodorsal and anteroventral surfaces; 2 apical setae (anterodorsal and anteroventral).  
 Wing. Vein R1 with conspicuous setulae on apical dorsal surface; Rs node setulose dorsally and ventrally; vein R 4+5 with setulae almost reaching to dorsally and ventrally; vein dm-cu slightly sinous, 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 with setulae, sternite 5 trapezoid, longer than wide, with many and sparse long setae (Fig. 43).  
Terminalia. Cercal plate longer than wide, with median fusion, with few and sparse long setae on apical half; surstylus greater than length of cercal plate (Fig. 44). Distiphallus small, about 1.5 times than length of pregonite; postgonite curved and shorter than epiphallus (Fig. 45).  
 Female. Length: Body: 6.0– 6.4 mm, Wing: 5.76–6.32 mm. Similar to male, but dichoptic, distance between eyes 0.33–0.35 times head width. Frontal seta with 4 pairs of setae; 1 pair reclinate orbital setae; inner vertical setae convergent; outer vertical setae divergent. Fronto-orbital plate with few setulae.   
 Type material   
 Holotype. Male: “ E. Papallacta \ (Quito Baeza) \ Ecuador. 2900 m. I-71 \ L. E. Peña col.[white printed label]”; “ Holotipo [red printed label]” (UTPL). Paratypes, 1 male, 3 females, same data as holotype (UTPL, DZUP); OTAVALO: 1 male, “ N. Perueho \ (Otavalo) Ecuador \ 2000 m. I-1971 \ L. E. Peña col.” (UTPL); CUENCA: 1 female, “ Faz. Maria Isabel, \ Sur Cuenca 2800 m. \ Rio Tarqui, \ Ecuador. XII-1970 \ L. E. Peña col.” (UTPL).   
 Distribution. ECUADOR: Azuay (Cuenca), Imbabura (Otavalo), Napo (Quito, E. Papallacta).   
 Etymology. Name in apposition. The specific epithet refers pays tribute to Dr. Marc A. Pollet, who lent us many specimens used in this study.
