Limnophora lamasi sp. nov. ( Figs. 25–30 )

Diagnosis. This species is easily differentiated by the dorsocentral setae 0 + 1, acrostichal seta not differentiated, vein R 1 setulose dorsally on apex, vein R 4+5 with setulae almost reaching the vein r-m, katepisternal setae 1 + 1.

Description. Male. Measurements (n = 4): Length: Body: 5.6–7.2 mm (5.6 mm). Wing: 5.76–6.0 mm (6.0 mm).

Color. Face silver pollinose. Antenna and arista dark brown. Palpus dark brown. Calyptera uniformly brownish with margin dark brown, lower more conspicuous. Halter yellowish. Wing hyaline yellowish with conspicuous 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 0.02–0.03 (0.03) times head width; eye finely and sparsely ciliated. Inner and outer vertical setae long and same length as ocelar seta. Frontal seta with 11–13 (13) pairs of setae; 2 reclinate orbital seta. Ocellar setae long; ocellar triangle a tuft of hairs. Flagellomere I about 1.8–4.0 (3.1) times pedicel length, ending before insertion of vibrissa. Arista with few fine hairs, shorter than the diameter of arista at base. Parafacial and fronto-orbital plate bare. Palpus cylindrical slightly dilated apically.

Thorax. Chaetotaxy. Acrostichals not differentiated; dorsocentrals 0 + 1; intra-alars 1; supra-alars 1; basal postpronotals 1; notopleurals 2; postsupra-alars 2. Scutellum with well developed lateral, apical scutellar. Anepisternum with 6–7 (7) long setae; katepisternal setae 1 + 1. Prosternum setulose.

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

Wing. Vein R 1 with conspicuous setulae on apical dorsal surface; Rs node setulose dorsally and ventrally; vein R 4+5 with setulae almost reaching to vein r-m, vein dm-cu sinous, apical portion of vein M bent toward vein R 4+5.

Abdomen. Tergite IV with 3 lateral 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 setae and two apically developed ( Fig. 25 ).

Terminalia. Cercal plate longer than wide, with median fusion, with long setae on inner apex; surstylus smaller than length of cercal plate ( Fig. 26 ). Distiphallus median, about 2.0 times than length of pregonite; postgonite slightly curved and shorter than epiphallus ( Fig. 27 ).

Female. Length: Body: 4.8–6.0 mm, Wing 5.2–6.56 mm. Similar to male, but dichoptic, distance between eyes 0.32–0.35 times head width. Six frontal setae, 2 fronto-orbital reclinate setae, inner vertical setae long and convergent. Fronto-orbital plate with few setulae.

Distribution. ECUADOR: Zamora-Chinchipe (Zamora).

Remarks. Some specimens have katepisternal 1:2 setae. All other characters did not vary.

Etymology. Name in apposition. The specific epithet pays tribute to Dr.Carlos José Einicker Lamas, an eminent Brazilian dipterist.
