Wings slightly dusky; veins and stigma brown; tegula light yellow.

Head: clypeus rugose, delimited by a scrobiculate groove dorsally, and ventrally projected forward; face rugose with a smooth swollen central region, and a scrobiculate groove in the inner margin of the eyes; frons excavated and rugose; vertex, temple and gena smooth; malar space rugose; oral cavity rounded, width equal to malar space; ocell-ocular distance twice the diameter of the lateral ocellus; 48 flagellomeres.

Mesosoma: covered with white setae, except for the center of mesopleuron which is smooth and shiny ( Fig. 1C ); pronotum rugose dorsally, lateral area of pronotum striate; pronotal groove wide and scrobiculate; propleuron smooth with setae inserted into punctuations; mesoscutal lobes smooth and with bristles inserted into punctuations ( Fig. 1B ); notauli scrobiculate, ending before scutellum in a rugose area; scutellar disk smooth and with setae inserted into punctuations; mesopleuron ( Fig. 1C ) with subalar sulcus costate; precoxal sulcus thin and smooth, almost the same size of mesopleuron; venter of mesosoma smooth and with setae inserted into punctuations; propodeum with areola, basal and lateral carinae present; basal median areas of propodeum smooth and with setae inserted into punctuations ( Fig. 1D ); propodeum areola rugose; metapleuron smooth with many setae inserted into punctuations, posteroventral region rugose.

Wings: fore wing vein r-m present; vein r equal to 0.55 length of 3RSa; m-cu vein in line with 2RS; 1 cu-a vein distal to 1M; first subdiscal cell open at apex, 2cu-a absent; hind wing vein M+CU 0.45 length of 1M.

Legs: covered with long setae; fore tibia with a row of seven spines; median tibia with a row of four to five spines; hind coxa smooth, basoventral tubercle present and well defined; lateral area of hind tibia with longitudinal groove.

Metasoma: full of setae, mostly on the sides; first metasomal tergum rugose with two parallel longitudinal carinae on the first two thirds of tergum, length of first tergum equal to its apical width; second metasomal tergum finely rugose; suture between the second and third metasomal tergum straight, deep and scrobiculate; third tergum finely rugose and with a slight transversal depression near half of tergum; terga 3–5 with a posterior smooth area bordered by a sinuous carina with small setae ( Figs. 1E, 1F ), terga 4 and 5 punctuated anteriorly; tergum 6 punctuated anteriorly and posteriorly similar to previous terga, but less defined; terga 7 and 8 smooth; ovipositor about twice length of metasoma.

Male: Unknown.

Distribution. Brazil (states of Amazonas and Maranhão)

Etymology. The specific name comes from the Latin pilosus in reference to the body full of setae.
