Figures 57–65

Material. Holotype ɗ, BRAZIL, State of Rio de Janeiro, Itatiaia, Maromba, 22º 22’S 44º 37’W, VIII/1946, Barreto col. ( MZSP); paratypes: 2 ɗ and 1 Ψ, same as holotype ( MZSP).

Diagnosis. Wing hyaline with brownish antero-distal macula; R2+3 reaching C far from R1, with wide distal concavity; areas around crossveins r-m and m-m pigmented; pterostigma rounded, large; meso-anterior incision of tergite IX on male rather short; many golden setae on scutum, scutellum and abdomen.

Male. Body length, 9.0–10.0 mm. Wing length, 5.8–6.2 mm. General color brownish gray. Eyes and ocelli brownish yellow, facets homogenous, ocellar tubercle gray. Gena gray, clypeus bare and brown. Antenna brownish yellow arista darker; scape bare, half the length of pedicel; pedicel approximately oval; first flagellomere oval, as long as pedicel ( Figure 58 ), with many golden setae. Maxillary palpus long, slender ( Figure 59 ). Proboscis and labella brownish to yellow. Occiput gray, with dark setae.

Thorax dark brown, scutellum lighter than scutum, with many golden setae. Halter bare, knob yellowish, stem darker. Coxae brownish gray, femora and tibiae yellowish. Wing hyaline with antero-distal brownish macula ( Figure 57 ); pterostigma rounded, large; areas around crossveins m-m and r-m pigmented; R2+3 reaching C far from R1, with wide distal concavity; R4 forking with almost right angle, without short appendage, with distal fold toward anterior margin; CuA2 and A1 fusing far from margin; crossvein m-m far from origin of M2.

Abdomen brownish gray, with golden setae on tergites. Gonocoxite and gonostylus brown; gonocoxite longer than wide; gonostylus long, slightly rounded distally, covered with long setae, a group of fine setae medially; aedeagus long; ejaculatory and gonocoxal apodemes relatively short, gonocoxal apodeme curved outwards; lateral ejaculatory process wide, curved inward ( Figure 61 ); meso-anterior incision of tergite IX short ( Figure 62 ); cercus brown.

Female. Body length, 10.0 mm. Wing length, 7.0 mm. Gena yellowish gray. Thorax and abdomen similar to male. Anterior margin of sternite VIII rounded, hypogynial valves with 7-8 long setae ( Figure 64 ); genital fork with anterior portion acuminate, distal apodeme short and curved ( Figure 65 ); cercus two-segmented, distal segment suboval ( Figure 63 ); long common spermathecal and spermathecal ducts; spermathecae spherical ( Figure 60 ).

Distribution. This species is known only from the type-locality.

Etymology. The species is named after the Brazilian entomologist Dr. João M. F. Camargo, eminent Meliponinae bee systematist.
