Description (male). Length 5.01, width 4.42 mm. Body rounded, strongly convex ( Fig. 1 View FIGURE 1 B). Head yellowish with triangular black spot; clypeus with anterior margin brownish, labrum dark yellowish. Eyes finely faceted, not emarginate; interfacetal setae absent. Antennal insertion exposed. Antennae 10-segmented; scape with convex external suface; pedicel distinctly narrower than scape; antepenultimate antennomere about 2.5 times longer than other segments. Clypeus short, transverse, anterior clypeal margin emarginate medially, with small blunt lateral projections. Labrum exposed. Mandibles bifid, with basal tooth. Maxillary palps securiform. Labial palps 3- segmented. Mentum cordiform. Pronotum black with yellowish anterior and lateral margins; narrow basal pronotal line present; basomedian projection of pronotum truncate. Prosternal process with complete carinae, joined anteriorly forming a triangle, with stem varying in length, reaching anterior margin of prosternum ( Fig. 9 View FIGURE 9 D). Each elytron reddish yellow with narrow black lateral margin; three small black spots: first spot smallest, on humeral callus, second on elytral disc, third near lateral margin ( Fig. 1 View FIGURE 1 A). Epipleura yellowish, explanate, and excavated to receive femoral apices. Middle part of pro-, meso- and metasternum black. Legs black, except apices of femora yellowish. Protibia slightly angulate near base, with parallel sides. Abdomen yellowish with yellow pubescence. Abdominal postcoxal lines recurved and incomplete, joined from hind margin of ventrite, oblique line absent. Ventrite 5 in male without apparent sexual caracters ( Fig. 1 View FIGURE 1 F). Male genitalia with basal lobe asymmetrical, shorter than parameres, apex rounded; parameres symmetrical, straight, apex rounded with short setae ( Figs 1 View FIGURE 1 G–H); sipho slender, long, slightly curved; siphonal capsule with outer arm well developed; apex slightly sinuate and wide ( Fig. 1 View FIGURE 1 I).
Female. Length 5.25, width 4.67 mm. Similar to male ( Figs 1 View FIGURE 1 E, 6A–J, 9C, E). Each elytron reddish yellow with narrow black lateral margin; four small black spots: first spot smallest, on humeral callus, second on elytral disc, third near lateral margin, and fourth apical, joined at suture ( Figs 1 View FIGURE 1 C–D). Genital plate transverse ( Fig. 1 View FIGURE 1 J). Spermatheca with rounded cornu and slender base with wide sinuate cornu projection ( Fig. 1 View FIGURE 1 J). Coxites with spoon–shaped setae and style with apical setae well developed; tergite with long setae curved at apex ( Fig. 1 View FIGURE 1 K).
Etymology. This species is named in honor of the dedicated entomologist and specialist on Odonata, Dr. Angelo B. M. Machado.
Geographical distribution. French Guiana (Point de vue du Bélvédère de Saül and Montagne des Chevaux) ( Fig. 11 View FIGURE 11 ).
Remarks. Menoscelis angeloi sp. nov. differs from all other species of the genus, except M. cordata sp. nov., based on the indistinct, very short grayish-white semidecumbent pubescence and the tibia slightly angulate near the base, with parallel sides ( Figs 6 View FIGURE 6 F–G). This species differs from M. cordata sp. nov. in the color pattern and female genitalia. The elytral color pattern of M. angeloi sp. nov. resembles M. stephani and M. flava sp. nov., but differs from these species in the size of the discal and lateral spots, shape of the spermatheca, and location of the spermathecal gland.
