Female.

Body size: 3.0 mm. Color: head light brown or darker brown with face and eye orbits lighter; scape light brown without lateral longitudinal brown stripe, flagellum light brown basally to dark brown apically; mesosoma usually brown or dark brown, mesoscutum lighter brown, at least along notauli; metasomal tergum 1 dark brown, tergum 2 light brown medially, remainder of terga slightly lighter than tergum 1; legs yellow; wing veins including stigma brown. Head: vertex transversely striate; frons transversely striate; face weakly striate, often smooth near eyes; temple in dorsal view broad, slightly bulging behind eye, width slightly greater than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance about 2.5 times diameter of lateral ocellus; 24-30 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum smooth; prescutellar furrow with 1 cross carina; mesopleuron smooth; precoxal sulcus smooth, shorter than mesopleuron; venter smooth; propodeum with basal median areas large, square, distinctly margined, rugose, basal median carina distinct, as long as half dorsal length of propodeum, areola not margined, areolar area rugose, lateral areas entirely rugose. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R present, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, apical width about equal to length; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum smooth or weakly costate medially at base, smooth apically; terga 4-7 smooth; ovipositor as long as metasoma.

Comments.

This species is distinguished by the unusually long basal median carina on the propodeum.

Etymology.

The specific name is from the Greek makros meaning long in reference to the long basal median carina of the propodeum.
