Remarks. Colour pattern of female is similar to that of male, and both sexes can easily be distinguished from their Mexican congeners by mesoscutum with a single subquadrate whitish spot in centre ( Fig. 12 ) while in other species mesoscutum is either uncolored or black with a pair of yellow longitudinal stripes. Ovipositor of M. macula ( Fig. 13 ) is similar to that of M. tabasco Kasparyan & Ruíz-Cancino.

Description. Female (first record). Fore wing length 5.3 mm. Antenna with 22 flagellomeres; flagellum 0.9× as long as fore wing; flagellomeres 1–3 subequal in length, 5–6× as long as wide; flagellomeres 1 and 2 combined 1.15× as long as maximum diameter of eye; flagellomeres 5–9 white, slightly compressed; flagellomeres 10–21 flagellomeres subcylindric, 1.3–1.5× as long as wide, slightly thickened, 1.6× as wide as basal flagellomere.

Face and clypeus mat, with fine dense punctures and short fine pubescence. Lower margin of clypeus sharp and with a small median tooth. Frons evenly granulate, with scarce fine pubescence. Gena subpolished, finely and sparsely punctate. Pronotum smooth, subpolished, without discernible punctures. Epomia absent. Mesoscutum evenly and finely granulate; lateral lobe anteriorly almost smooth; posterior 0.4 of mesoscutum with longitudinal striation reaching prescutellar groove. Scutellum subpolished, with scarce fine punctures. Mesopleuron smooth, with moderately fine punctures, distinctly striate in its upper front corner; speculum polished. Metapleuron subpolished, with scarce fine punctures in its anterior half and with very fine and dense oblique striation in posterior half. Propodeum with fine transverse striae; only basal transverse carina and pleural carinae present.

Fore wing with areolet open, receiving second recurrent vein (2m-cu) at basal 0.3; areolet as high as portion of second recurrent vein between bulla and areolet; nervulus (cu-a) opposite basal vein (Rs&M); postnervulus intercepted in its anterior 0.4. Hind wing with brachiella (distal section of 1A) absent.

Hind coxa mat, alutaceous, with rather dense, shallow, moderately fine punctures. Tergite 1 finely granulate. Tergite 2 evenly covered with very dense fine punctures. Tergites 3 and 4 smoother, with very fine punctures on very finely granulate background; subsequent tergites almost smooth, with hardly discernible granulation and punctures. Ovipositor sheath about 0.75× as long as hind tibia. Ovipositor apically with lower valve expanded dorsally ( Fig. 13 ); distance from nodus to apex of upper valve equal to 0.75× length of hind tarsomere 2.

Antenna brownish-black; scape pale yellow ventrally; flagellomeres 5 to 9 white with brownish markings ventrally. Head white with black median wide band extending from antennal sockets to ocellar area and further to occiput; occiput black except for its lower 0.3. Mandible brownish with dull whitish spot at base; palpi with two basal segments white and following segments brownish. Propleuron white; pronotum whitish yellow anteriorly and black posteriorly, with small white markings in its upper hind corner and on upper margin before notaulus. Mesoscutum black with median subquadrate white mark ( Fig. 12 ). Scutellum dorsally and tegula white. Prepectus black; mesopleuron white with narrow longitudinal black stripe below subtegular ridge, and with black mark on mesopleural pit ( Fig. 11 ). Metanotum black with postscutellum dorsally white. Metapleuron with upper and lower divisions white except for narrow wedge-like fuscous mark in its lower front corner. Propodeum before basal transverse carina black with a pair of submedian whitish spots. Pterostigma pale yellow. Legs pale orange with fore coxa and trochanter white, mid coxa and trochanter whitish yellow, hind tarsomeres 2 and 3 white, and two apical tarsomeres of all tarsi brownish dorsally. Metasoma light orange with tergites 2 and 3 dorsally darkened at base, tergite 4 dorsally slightly infuscate mediobasally, and tergites 1–3 with widely whitish apically ( Fig. 11 ).
