Chrysopilus caligatus sp. n.

Figures 84–92

Material. Holotype ɗ, BRAZIL, State of Rio de Janeiro, Nova Friburgo, Mury, 22º 10’S 42º 19’W, I/1966, Gred & Guimarães cols. ( MZSP); paratypes: 1 Ψ, same as holotype ( MZSP); 1 ɗ, idem but I/1970, Guimarães & Papavero cols. ( MZSP).

Diagnosis. Wing maculated; crossvein m-m close to origin of M2; apex of maxillary palpus curved; gonostylus swollen, rounded distally; ejaculatory apodeme long, surpassing base of gonocoxite; gonocoxal apodeme short.

Male. Body length, 9.0– 9.5 mm. Wing length, 6.0– 6.6 mm. General color brown. Brownish yellow eyes, facets homogenous, ocellar tubercle dark brown, ocelli yellow. Gena, clypeus and antenna brown, clypeus bare. Scape bare, half the length of pedicel; pedicel cubic; first flagellomere suboval, shorter than pedicel ( Figure 85 ). Maxillary palpus long, slender, curved apically ( Figure 86 ). Proboscis and labella brownish yellow. Occiput brownish gray, with dark setae.

Thorax uniformly brown, with golden setae on scutellum, tibiae lighter than femora. Halter bare, stem brownish yellow, knob dark brown. Wing maculated ( Figure 84 ); pterostigma pigmented, long; surroundings of crossveins pigmented; R2+3 reaching C, far from R1, without distal sinuosity; R4 forking with almost right angle, slightly curved distally toward anterior margin, without short appendage; CuA2 and A1 fusing far from margin; crossvein m-m close to origin of M2.

Abdomen homogeneously dark brown, tergite of first segment with silvery setae, forming an iridescent band. Gonocoxite brown; gonostylus brownish yellow, swollen, slightly rounded distally, with long setae; aedeagus and ejaculatory apodemes long, the later exceeding base of terminalia; gonocoxal apodeme short; lateral ejaculatory process slender, parallel to ejaculatory apodeme ( Figure 88 ); meso-anterior incision of tergite IX deep ( Figure 89 ); cercus brown.

Female. Body length, 9.0–10.0 mm. Wing length, 6.0– 6.5 mm. Thorax and abdomen similar to male. Anterior margin of sternite VIII rounded, hypogynial valves with at least six long setae ( Figure 91 ); genital fork with anterior end strongly acuminate, distal apodemes wide ( Figure 92 ); cercus two-segmented, distal segment elongated ( Figure 90 ); common spermathecal ducts short, spermathecal ducts long; spermathecae slender, oblong ( Figure 87 ).

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

Etymology. The species name comes from the Latin word caligatus , common soldier, as a reference to the wing brown stripes, resembling a military dress.
