Mesembrinella apollinaris Séguy, 1925: 196   . Lectotype male (MNHN), not examined. Type locality: Villavicencio, Colombia. Mesembrinella apollinaris: Peris & Mariluis (1984: 259)   ; Kosmann et al. (2013: 77); Wolff (2013: 121); Wolff & Kosmann (2016: 866); Marinho et al. (2017: tab. 1); Cerretti et al. (2017: tab. 2).

Diagnosis. A very large species [a single female was examined by us, measuring 17 mm in length; Guimar„es (1977) gave a body length of 15 mm for this species]; postpronotal setae 3x 3; stem vein bare; wing heavily infuscated, dark brown: anterior half all dark, posterior half with infuscation around veins; dorsum of abdomen without heavy, irregular, tomentose pit-like spots (see Fig. 103 View FIGURES 103–104 ); supravibrissal setae dark reddish-brown; section IV of wing 0.75 of section III; palpus brown; scutellum without discal setae.

Redescription. Male [none available for examination; the information given here is taken from Guimar„es (1977)]. Frons 0.05 of head width at vertex; thoracic chaetotaxy: ac 2:1, dc 3:3, ppn 3x 3, kat 2:1, 1 pair converging ap, 1 sa, 1 lat, 1 bas, 1 pb, disc absent. [Guimar„es (1977) illustrated the epandrium, cerci and surstyli (figs 70, 87) and phallus (figs 116, 137).]

Female [one specimen examined and dissected]. Frons 0.26/1 of head width at narrowest. Fronto-orbital yellow with silvery tomentum; frontal vitta broad and reddish-brown; frontal setae ascending to vertex; parafacial with heavy, shiny silvery tomentum; gena dark orange with faint silvery tomentum, unusually narrow with typical horizontal row of about five stout black setae midway; postgena orange with dark setae; occiput with gleaming silvery tomentum and long wiry whitish setae, median occipital sclerite shiny dark reddish-brown; antenna: pedicel dull orange, first flagellomere brown, base of arista orange, remainder brown; palpus nontypical, brown [not orange)]; eye with median facets about 3x size of lateral facets; ocellar triangle medium-sized, ocelli about equal in size; supravibrissal setae dark reddish-brown, in cluster near base and in single row above, ascending about 50% of distance to antennal base.

Thorax reddish-brown with a pair of pale tomentose stripes; pleura reddish-brown with weak, pale tomentum; chaetotaxy: ac 2:1, dc 2:3, ia 1, ph; ppn 3x 3, kat 2:1, meral setae pattern typical but setae very fine and weak, crossed ap, 1 sa, 0 lat, 1 bas, 1 small pb, 0 disc [unusual for this species-group]; subscutellum moderately developed; spiracles medium-sized, pale; legs brown, apex of for femur orange, mid and hind femora with orange distal half. Wing tinted brown with heavy black infuscated area along costa to R 2+3; subcostal sclerite setose (setae tending to blend in with sclerite); basicosta and tegula typical; section IV 0.75 of section III; disc of upper calypter tan with pale area ventrally, rim dark brown with dark setae; disc of lower calypter tan, rim yellow with yellow setae.

Abdomen entirely shiny reddish-brown with purple reflections and weak pale tomentum; rear of T4 with a few stout dorsolateral marginal setae, disc of T5 with sparse, fine setae only. Terminalia. T6 of RU shape; T7 narrowed midway; T8 thin and divided midway; epiproct complete ( Fig. 302 View FIGURES 300–305 ); ST6 very broad, rectangular; ST7 also wide ( Fig. 346 View FIGURES 326–349 ); ST1–5 of equal width ( Fig. 431 View FIGURES 424–438 ).

Material examined. Colombia, Meta. 1 ♀, 23 km NW Villavicencio Qbda [Quebrada] Susamuco , 1000 m, 5.iii.1972, S. & J. Peck ( CNC)   .

Distribution. Colombia.

Remarks. The type series consists of the lectotype male and two female paralectotypes collected from the same general area as the lone female specimen examined for this study. This species was not seen from any other area of the Neotropics during this study. One sequence from GenBank ( KR820707 View Materials ) was added to the barcode analysis. It was distinct from other species and was recovered close to M. umbrosa   ( Fig. 488 View FIGURE 488 ).
