Mesembrinella semihyalina Mello, 1967: 73. Holotypemale (FIOC), not examined. Type locality: Parque Sooretama, Espirito Santo, Brazil. Mesembrinella semihyalina: Toma & Carvalho (1995: 138); Kosmann et al.(2013: 78); Wolff (2013: 121); Marinho et al.(2017: tab. 1); Cerretti et al.(2017: tab. 2).
Diagnosis.A medium-sized fly averaging 12.2 mm(11–13/5) in length. Wing infuscated; supravibrissal setae brown; subcostal sclerite setose; wing with section IV 0.23 of section III; male phallus in dorsal view with weak serrations ( Fig. 178); legs entirely orange. Male frons about 0.06 of head width at narrowest; epandrium, cerci and surstyli as in Figs. 87–88. Female T6 of WUshape ( Fig. 318). Redescription. Male.Head. Frons 0.063 (0.06–0.07/3) of head width at narrowest. Fronto-orbital and parafacial pale silvery when viewed from above, pale orange when viewed from below; frontal setae ascending halfway to vertex; frontal vitta dark orange, obliterated midway; gena pale orange with horizontal row of few dark setae anteriorly, otherwise with small dark setae; postgena pale yellow with fine yellow setae; occiput with pale yellow tomentum and yellow setae; median occipital sclerite shiny black; antenna orange, first flagellomere with pale tomentum, arista dark orange; palpus typical; eye with median facets 3xsize of lateral facets; ocellar triangle medium-sized, anterior ocellus 2xsize of posterior ocelli; short row of tan supravibrissal setae on facial ridge ascending, about 1/6 of distance to antennal base. Thorax. Dorsum with alternating dark brown areas with yellowish tomentose stripes; pleura dark orange with whitish tomentum; spiracles small, pale orange; chaetotaxy: ac variable, 2:1or 2:2, sometimes one or more setae missing, dc 2:3, ia 1, ph 1, ppn 3x3, kat 1:1, meral setae typical, 1 pair of parallel ap, sa and lat absent, 1 bas, 1 weak pb, 1 disc; subscutellum moderately developed; spiracles medium-sized, pale yellow; legs entirely orange. Wing faintly infuscated along distal 2/3 of costa through R 2+3and along veins; basicosta and tegula pale orange; section IV 0.23 of section III; upper calypter with pale disc and dark rim with reddish setae; lower calypter with pale disc and rim, rim with long pale setae. Abdomen. T1+2 dark orange; T3–T5 shiny blue with patchy white tomentum; rear margins of T4–5 with stout setae; disc of T5 with dense, medium-long, fine setae only. Terminaliain lateral view with surstylus broad, with gradual backward curve, cercus with apical hook ( Fig. 87); in posterior view, base of cerci broad, relatively short and stout, narrowing apically to chisel-like tip ( Fig. 88); phallus in lateral view with epiphallus short and stout with slight backward curve ( Fig. 177); in dorsal view, hypophallic lobes slightly rounded with shallow, moderate serrations ( Fig. 178). T6, STS7+8, pre- and postgonite, ejaculatory sclerite and ST6 as in Fig. 231; ST2–5 as in Fig. 274. Female.Similar to male except frons 0.248 (0.23–0.26/5) of head width at narrowest. T6 of WUshape; T7 continuous; T8 narrowed midway; epiproct divided midway ( Fig. 318); ST6–8 and hypoproct as in Fig. 362; spermathecae filiform ( Fig. 403); ST1–5 as in Fig. 447.

Distribution. Brazil. Remarks. Bonatto (2001)argued that this species is a synonym of M. abaca[here considered a synonym of M. socors], but M. semihyalinahas a distinct, dark infuscation in cells r 1and r 2+3, while M. socorshas, at most, a faint yellowing in the r 1cell along the costa. The known range of M. semihyalinais Brazil, whereas M. socorsis known only from Central America. Two specimens of M. semihyalina( TLW392 and TLW432) were barcoded; they clustered together, close to M. anomalaand distant from M. socors(genetic distance 12%) ( Fig. 488), supporting the morphological differentiation between these two species.
