Male.Body length: 2.11–2.47 mm. Wing length: 2.11–2.33 mmlong, 0.59–0.75 mmwide (n = 2). Similar to  Mberu amorimi  sp. nov.in both general habitus and chaetotaxy, except as noted. Body mostly metallic black. Head( Figs 10B, C). Palpus brown, yellowish on edges and apex; proboscis dark brown; postpedicel dark brown, triangular and pubescent, about 1.3 times longer than basal width; stylus about 5.2 times longer than postpedicel. Thorax( Fig. 10B). Metallic black, with some green or blue reflections. One presut spal s and two large psut spal s; two dark pprn s, one strong and one tiny. Wing.RMx ratio = 4.5, CuAx ratio = 0.4. Legs( Fig. 10A). Mostly brown; coxa I, II and III sclerotized. Yellow at apex of femur I, base of tibia I, apex of femur II and apex of femur III. Leg I.It1–5 with ventral surface covered by small dark setae. Leg II.Femur II covered by small setulae, ventral surface completely bare without pv; tibia II with major setae at ad 1/4 and 1/2 and one ad apical seta. Leg III.Coxa III with one conspicuous, long and dark seta near base; femur III with one av row of 3–4 setae decreasing in size towards apex. Relative podomere ratios: I: 6.9/ 7.3/ 3.8/ 2.6/ 1.6/ 1.3/ 1; II: 9.4/ 9.3/ 6.4/ 3.8/ 2.2/ 1.3/ 1; III: 8.7/ 10.4/ 2.9/ 3.5/ 2.1/ 1.3/ 1. Abdomen.Mostly black, with some dark blue to green reflections; tergite 2–5 with anterior shiny green bands laterally. Hypopygium( Fig. 11A–H). Epandrium elongate, twice longer than high, dark ( Fig. 11A, B); MEp elongate, digitiform, with two small, dorsal setae near apex ( Fig. 13C, E); DSur and VSur covering internal appendages ( Fig. 11A, B); VSur ( Fig. 11C) enlarged, twice higher than DSur, sclerotized at apex; DSur ( Fig. 11D) elongated, twice wider than height. Hypandrium basally fused to epandrium. Phallus straight, without apical projection ( Fig. 11G). Cercus ( Fig. 11F) divided in two parts, ventral part stout, rounded, with 3–4 spines ventrally and one long anterior seta, dorsal part rounded and covered by fine setae, with one long, flattened seta apically. Female.Body length: 2.55–3.32 mm. Wing length: 2.52–3.24 mmlong, 0.78–1.04 mmwide (n = 5). Similar to male, except as noted. Head.Face broader (about as broad as ocellar tubercle). Wing.RMx ratio = 2.7, CuAx ratio = 0.4. Legs. Leg II.Tibia II with av at 1/4, 1/2, 3/4, and at apex, one anterior seta at apex, two ad at 1/3 and 2/3, and two dorsal setae at 2/3 and at apex. Relative podomere ratios: I: 7.1/ 7.9/ 3.6/ 2.8/ 1.9/ 1.1/ 1; II: 6/ 7.2/ 4.5/ 2.8/ 1.8/ 1/ 1; III: 9.5/ 10.8/ 2.6/ 3.7/ 2.5/ 1.3/ 1. Abdomen.Tergites 1–5 covered by short setae.

In  M. amorimi  sp. nov., the legs are completely yellow ( Fig. 8A) and MEp stout, approximately 2.5 times less than VSur height, with dorsal face rough ( Fig. 9C, F).   Distribution( Fig. 24). Brazil: states of Goiás(Cerrado biome) and São Paulo(Atlantic Forest Biome). 5179609322 2022-01-17 2022-01-19 2022-01-17 MZUSP Capellari Brazil -22.983833 Juquiratiba, Faz.
