 Male. Head: face 1/2 as long as eye width, shiny yellow, sparsely white pollinose laterally, yellow pilose laterally; gena brownish yellow; frontal triangle yellow, black and white pilose; vertical triangle narrow, elongate, black, brownish-black pollinose except shiny posterior to ocellar triangle, black pilose; occiput black, pale yellowish bronze pollinose, with thick white pile on ventral 1/2, with thin yellow pile dorsally, with a short row of black pile superiorly; antenna orange, black pilose; arista brown.

Legs: pro- and mesolegs yellow except coxae black, yellow pilose; metacoxa yellow, yellow pilose; metafemur yellow except brown subapical annulus, yellow pilose except black pilose on ventroapical 3/4 and apical 1/4; metatibia yellow, black pilose on basal 1/2, yellow pilose apically; metatarsus brown, black pilose (Fig. 20). Wing: hyaline, extensively bare, microtrichose only: on apical 1/6 of cell R1, apical 2/3 of cell R2+3, apical 3/4 of cell R4+5, apical 1/2 of cells DM and Cu1, and on anal lobe; alula broad, as broad as cell BM apically, microtrichose (Fig. 16).  
 Abdomen: 1st tergum yellow except narrowly black apically, yellow pilose except narrowly black pilose on apicomedial margin; 2 nd tergum yellow except brownish black on apical 1/3, yellow pilose except black pilose apically; 3 rd tergum yellow except brownish black apical 1/3, with small basomedial black punctum, black pilose; 4 th tergum yellow except brownish black apical 1/3, with small basomedial black punctum which is connected to apical dark area by dark submedial vitta, black pilose; 5 th tergum yellow except with large basomedial black elongate triangular macula on basal 1/3, black pilose; sterna yellow, yellow pilose (Fig. 34). Male genitalia: surstylus broader on medial 1/3; postanal process 1/3 as long as surstylus; aedeagus all enlarged; superior lobe somewhat rounded with short anterior extension, with scattered hairs, longer on anterior margin (Figs. 62–64).   
 Female. Similar to male except for normal the frons black, bronze pollinose, black pilose; fronto-orbital plate. black on 1/3 superior and yellow on 2/3 inferior, bronze pollinose, black pilose. Anterior anepisternum bare. Female genitalia: 9 th tergum with triangular black macula medially; epiproct reduced; cercus slender; hypoproct somewhat triangular; 9 th sternum somewhat quadrangular; three spermatecae eliptical, with the same size (Figs. 122–124).   
Length: body 6.5–7.5 mm. Wing 5.0–6.0 mm.  
 Discussion. Toxomerus papaveroi is very similar to T. duplicatus and T. paraduplicatus, but differs from them in having a supracoxal yellow macula present, more extensively bare wing and distinct male genitalia.   
 Etymology: This species is named after Nelson Papavero, in recognition of his contribution to our knowledge of the Neotropical Diptera fauna.
