Sumapazomyia quimbaya Ramos-Pastrana, Uni-Urrego & Fogaça sp. nov.

( Figs 1–18 )

Diagnosis. Male. Six pairs of frontal setae; postpedicel 2x the length of pedicel; proepisternum with two long, stout and black setae; proepimeron with a row of three setae, the central one stout and the longest, anepisternum setulose near notopleuron and anepimeron; sternite 5 with two long, stout and brown setae in the lobes; cercus with lateral margins slightly straight, hypandrium with upper anterior margin sinuous, with margins slightly straight; epiphallus straight.

Measurements Male. Body length: 7 mm (holotype).

Description. Coloration. Ground color grey. Frons and fronto-orbital plate dark brown. Parafacial and gena with silvery pruinosity. Ocellar triangle dark brown. Antenna, arista and palpus dark brown. Mesonotum brown. Pleurae grey. Calypter whitish. Halter yellowish. Wing light brown. All legs grey to brown. Abdomen brown with lateral grey pruinosity of all tergites.

Head ( Figs 1–3 ). Ocellar triangle narrow, extending to the ptilineal suture. Six pairs of frontal setae; one pair of upper orbital setae; ocellar setae well developed; postocellar setae same length as ocellar pair; inner convergent and outer divergent vertical setae shorter than ocellar setae. Antenna ( Figs 2–3 ). Postpedicel 2× length of pedicel. Arista long, wider on basal fourth, shortly pubescent.

Thorax ( Figs 1, 4 ). Postpronotal lobe, presutural scutum and scutellum with a few setulae. Acrostichal setae 1+3, setae differentiated from covering setulae; intralar setae 1+2; basal postpronatal setae 2; supra-alar setae 1+1; intrapostalar seta developed. Notopleuron with 2 similar setae, without cilia covering it. Scutellum with sub-basal and an apical pair of stout setae. Prosternum bare, proepisternum with two long, stout and black setae; proepimeron with a row of three setae, the central longest and stout, anepisternum setulose near notopleuron and anepimeron; anepimeron bare; katepisternum setae 1+1+1; katepimeron bare; meron bare.

Wing ( Fig. 5 ) length 5.9 mm. Long, slender, anal lobe weakly developed. Vein R 4+5 and M 1 slightly curved downwards and parallel on apical part; vein dm-cu almost straight; vein CuA 2 +A 1 short; vein A 2 long and inconspicuous.

Legs ( Fig. 1 ). Fore coxa with two rows of long, stout and black setae ventrally. Fore femur with d, pv, p and pd complete rows of setae and v only in basal half. Fore tibia with one long, stout, erect and black setae pd and one apically pd about 1/2 as long as postpedicel. Mid coxa with a row of long, stout and black setae in lower margin (the rest of the leg lost). Hind coxa with rows in the anterior and posterior margins basally. Hind femur with irregular ad, av, v and pv rows of setae, longer on basal half. Hind tibia with irregular ad, av, v, d and pv rows of setae and two apical setae (av and v).

Abdomen ( Figs 1, 6 ). Longer than thorax. Tergites I–VI with lateral setae slightly more developed than the others. Sternite 5 with lower margin concave, upper margin rounded, covered with setae, scarcer in the basal half and two long, stout and brown setae in the lobes ( Fig. 7 ).

Terminalia ( Figs 8–13 ). Epand large, rounded and divided in the center ( Fig. 8 ); cerc setulose, longer than wide, with lateral margins slightly straight, basal half rounded, apical half V-shaped ( Figs 10–11 ). Sur long, about the same length of cercus ( Figs 8–10 ). Phallic complex: hypd short, as long as it is wide, upper anterior margin sinuous; pregt longer, longer than wide, somewhat triangle-shaped; pgt short, rounded, with membranous apex; epiph long, straight, with membranous apex; distph curved with membranous apex; phapod long and curved on apex ( Figs 12–13 ).

Female ( Figs 14–17 ) (n= 2). Body length 6.7–7.7 mm. Similar to male, only differing in the where the gray pruinosity is less on the scutum, scutellum and abdomen.

Terminalia ( Figs 15–17 ). Ovipositor long with microtrichia on sternites 6, 7 and 8; cerci short; segments 6 and 7 not fused; epiprct not modified, setulose, about 2x as high as wide; hyprct well developed, somewhat triangular, with four differentiated setae, one in each lateral margin and two apically; tergites 6 and 7 membranous; three rounded spermathecae.

Type material. HOLOTYPE ♂: COLOMBIA, Risaralda, SFF [Santuario de Fauna y Flora] Otún Quimbaya, Cuchilla camino, 04º44′N / 75º35′W, 1960 m [eters], 19.VI–7.VII.2003, Trampa Malaise, López, G. Leg. (1 ♂ IAvHE 223999) (photographed specimen) . PARATYPES: idem (1 ♀ IAvH-E 224029) (photographed specimen) / idem Cundinamarca, PNN [Parque Nacional Natural] Chingaza, Alto de la mina pedregal, 04º31′N / 73º45′W, 3610 m [eters], 13–27.VIII.2003, Trampa Malaise, E. Niño Leg. (1 ♀ IAvH-E 224062) .

Etymology. Sumapazomyia quimbaya sp. nov. is named after the acronym for the Santuario de Fauna y Flora Otún Quimbaya, name of type locality. Treated as a noun in apposition.

Geographical distribution. Colombia (Cundinamarca, Risaralda) ( Fig. 18 ) .

Habitat. Specimens were collected in the Otún Quimbaya Flora and Fauna Sanctuary, where the vegetation is composed of Andean cloud forests of the Western Cordillera and the Chingaza National Natural Park with frailejon vegetation typical of the paramo of the Andean region in the Central Cordillera of Colombia ( Serna, 2018), the same locality where the type species of Sumapazomyia , S. inusitata , was collected, thus indicating that Sumapazomyia is possibly well distributed throughout the Colombian Andean Region.
