Summary 
Biconus is a “trachysphyroid” mesostenine found in Andean wet 
forests and in the Coastal Desert of Peru. It is recognizable by its 
brown blotched wings; lack of tyloids on male flagellum; mat 
mesoscutum; arched mediella; anally situate axillus; sharply grooved 
hind coxal base; deeply cleft female 4th tarsomere; nearly round 
propodeal spiracle; unarmed petiolar base; and subligulate to coni- 
cal, prominent (but never spiniform) propodeal cristae. There are 3 
species: B. atroruber Townes from Ecuador (white band on flagel- 
lum, body ferruginous and black, fore wing with 2 brown areas); B. 
apoecus n. sp. from the Peruvian Coastal Desert (similar to B. 
atroruber but without a white flagellar band); and B. subflavus from 
Peruvian montane forest (mesosoma and gaster orangish, fore wing 
with 1 brown blotch).
