Diagnosis. First flagellomere reniform, golden yellow; wing brownish near posterior margin and around crossveins, male cercus golden yellow; female hypogynial valves of sternite VIII with only two long setae.

Male. Body length, 8.8–9.5 mm. Wing length, 6.5–7.0 mm. General color dark brown. Eyes black, homogeneous facets, ocellar tubercle dark gray, ocelli green. Gena and clypeus grayish to brown, clypeus with dark setae. Antenna brown, except for golden yellow first flagellomere; scape bare, as long as pedicel; pedicel oval; first flagellomere reniform, longer than scape ( Figure 2 View FIGURES 1 – 4 ). Maxillary palpus long, medially enlarged (Figure 3). Proboscis and labella brownish yellow to brown. Occiput gray, with silvery iridescent setae.

Thorax brown, scutellum lighter, with scarce golden setae. Halter stem dark brown, knob brownish yellow. Legs brown. Wing brownish near posterior margin and around crossveins ( Figure 1 View FIGURES 1 – 4 ); pterostigma long, reaching C; R2+3 reaching C close to R1, without distal sinuosity; R4 forking with almost right angle, short appendage on R4 present in some specimens; CuA2 and A1 fusing far from margin; crossvein m-m not far from origin of M2.

Abdomen brownish yellow, yellow stripes on tergites 1–2. Gonocoxite and gonostylus brownish yellow; terminalia wider than long; gonostylus long, rounded distally; aedeagus short; ejaculatory and gonocoxal apodemes long, the former reaching base of terminalia; lateral ejaculatory process wide, projected obliquely (Figure 5); meso-anterior incision of tergite IX short ( Figure 6 View FIGURES 5 – 9 ); cercus golden yellow.

Female. Body length, 9.0– 11.7 mm. Wing length, 7.8–10.0 mm. Thorax and abdomen similar to male. Anterior margin of sternite VIII acuminate, hypogynial valves with only two long setae ( Figure 8 View FIGURES 5 – 9 ); genital fork (sternite IX) with anterior end strongly acuminate, distal apodeme short ( Figure 9 View FIGURES 5 – 9 ); cercus two-segmented, distal segment quite elongated ( Figure 7 View FIGURES 5 – 9 ); common spermathecal ducts short, spermathecal ducts long; spermathecae spherical ( Figure 4 View FIGURES 1 – 4 ).

Distribution. Chrysopilus balbii sp. n. is widely distributed in southern and southeastern Brazil, occurring from Santa Catarina to Rio de Janeiro. Some females found in Anápolis, State of Goiás, are similar to C. balbii , but these need further examination, since males from that area are not known and the terminalia of these females were not dissected.

Etymology. This species is named after Maria Isabel Protti de Andrade Balbi, biologist of the Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, who has been extremely important for the formation of many dipteran students and researchers.
