Description. Holotype Ƥ. Body length: Ƥ 3.9–4.1 mm; ♂ 3.7 mm.

Head ( Figs 5 View FIGURES 5 – 8 , 13 View FIGURES 13 – 16 , 21 View FIGURES 21 – 23 ). Transverse in dorsal view, 2.4–2.5 times wider than long; 1.27–1.30 times wider than mesoscutum. Eye, in lateral view, 2.5–2.8 times longer than temple. In frontal view, head about twice as wide as high; malar space 0.43–0.50 times the eye height. Face granular-rugulose, with a polished area medially from above clypeus to its mid height; this area is dorsally limited a by a small depression; dorsal depression arises some irregular longitudinal striations, extending up to antennal bases; 2.0–2.3 times wider than high, 0.53–0.57 as wide as head. Gena smooth. Clypeus protruding dorsally, not carinately margined. Mandibles densely setose except on teeth, ventral tooth longer than dorsal. Frons and vertex finely rugose; stematicum elevated within a circular smooth depression bordered by concentric rugosity, but smooth posteriorly ( Fig. 13 View FIGURES 13 – 16 ). Maximum diameter of posterior ocellus equal to distance between posterior ocelli; shortest distance between eye and ocellus 3.0–3.4 times the maximum diameter of posterior ocellus. Occipital carina distinct, absent mid-dorsally. Antenna 1.2 times the length of the body; flagellomere setae shorter than its width; flagellum with 30–32 joints, flagellomeres becoming shorter gradually toward apex. Maxillary palpi 5-segmented, labial palpi 4-segmented.

Mesosoma ( Figs 10 View FIGURES 9 – 12 , 13 View FIGURES 13 – 16 ). 1.6–1.7 times longer than high, 1.0–1.2 times higher than wide. Anterior declivity of mesonotum vertical; median mesonotal lobe bare along the midline, and deeply indented medially; lateral lobes bare medially, setae restrict to its margins. Notauli very deep and crenulate anteriorly converging in a rugose patch posteriorly, the sculpture area extending 0.37–0.48 the length of mesoscutum and bearing a median carina. Prescutelar pit divided by single carina in two deep, and polished pits. Metanotum laterally smooth, weakly crenulated centrally. Propodeum rugose on posterior half, smooth anterodorsally except for median carina, the unsculptured area separated by a distinct carina from the rugose lateral sculpture; median carina became indistinct at rugose posterior area; posterolaterally with short tubercles; lateral carina between propodeum and metapleuron indistinct to absent. Metapleuron rugose. Sternaulus shallow and rugose anteriorly, absent posteriorly; epicnemial carina weak, but present ventrally, not extending dorsally onto lateral portion of mesopleuron. Pronotum smooth laterally. Midventral line of mesopleuron set within crenulate groove, widened posteriorly, narrow and shallow anteriorly.

Legs: Fore tibia with some sparse thickened setae anterodorsally. Hind femur 3.55–3.87 times longer than broad; inner hind tibial spur 0.2 times the length of hind basitarsus; hind basitarsus 0.75 times the length of tarsomeres 2–5; tarsi clothed with short setae ventrally, setae long and sparse dorsally, longest dorsal setae longer than second tarsus; tarsal claws simple.

Wings: Fore wing 2+3RS slightly shorter than 4Rsa; 2CUa present; RS+M weakly sinuate; 1CU-a postfurcal to 1M, proximal segment of 1M 1.1–1.3 times longer than 1CU-a.

Metasoma ( Fig. 17 View FIGURES 17 – 20 ). T1 rugulose, without median longitudinal carina; T2 longitudinally striate with incomplete median carina; reminder metasoma smooth and polished, except for a transverse crenulated groove at base of T3. Petiole short, 0.72–0.77 times longer than apical width, apex about 1.9 times wider than base, broadest subapically, narrowed at apex; base narrow, flared sub-basally at dorsope. Ovipositor about as long as body, 3.2 times longer than hind tibia.

Color. Head and antenna dark brown; gena near mandibles and mandibles yellow, except for darker teeth; maxillary and labial palpi whitish. Mesosoma yellowish, but apex of scutellum, propodeum and metapleuron dark brown. Legs yellow, except mid and hind femur, and all last tarsomeres brown. Metasomal terga brown, first metasomal tergite darker; metasomal sternite light brown; ovipositor yellowish, apex brown; sheaths light brown. Wings infumate, stigma dark brown, veins brown, tegula yellow.

Variation. The female paratypes are quite similar to the holotype, but the median longitudinal carina at second metasomal terga is incomplete. In one paratype the hind tibia is brown.

Male. Similar to female; head less transverse, 2.3 wider than high in dorsal view; smaller eyes; ocelli larger, distance between eye and posterior ocellus 2.67 times the maximum diameter of ocellus; T1 more slender, 0.9 times longer than apical width.

Comments. This species is similar to M. curta in some diagnostic features such as the orange thorax, contrasting with the brown head and propodeum, relatively small size, and face sculpturing; but it has smaller eyes, face entirely brown to dark brown, and longer antenna. The sculpturing of frons and vertex, which appears as concentric rugosities around stematicum, is a unique feature of this species. Additional diagnostic features are: head wide, in frontal view twice as wide as high; prescutelar pit divided by single carina in two, deep, polished pits; midventral line of mesopleuron set within a crenulate groove, widened posteriorly, narrow and shallow anteriorly.

Etymology. The species was named in honor of the Brazilian entomologist Ângelo Moreira da Costa Lima.
