( Figs 8–12 )

Type material examined. HOLOTYPE: J ( MZFS), labelled: ‘Manacapuru ( AM) / Cajatuba, Km 69/3/ 3CDC copa / 9.X.1998 [white label] ’; PARATYPES: 1 J ( MZFS), labelled: ‘ BRASIL, AM / Manacapuru / Cajatuba, Km 69/3/ CDC copa Lote 011 / 20.IV.1998 / Col. RQ, RN, PE [white label, printed] ’; 1 J ( MZFS), labelled: ‘ BRASIL, AM / Manacapuru / Cajatuba, Km 69/3/ CDC / 08.XI.1999 [white label, printed] ’; 1 J ( MZFS), labelled: ‘ BRASIL, AM / Purupuru , Est. / Nunes de Melo / Km 4 (base de árvore / 24.XI.1998 [white label, printed]’.

Diagnosis. Palpus with segment 4 of palpus 1.2 times the length of third segment; radial fork apical to medial fork; CuA 2 ending approximately at the same point as medial fork; posterior arms of gonocoxite subrectangular in dorsal view with acute apex, convergent, with feathered bristles on entire surface; gonostylus present, blade-shaped, with truncate apex; cercus teardrop-shaped in ventral view; ejaculatory apodeme long, 0.9 times the length of gonocoxal arm.

Description. Male. Palpus four segmented with sensilla in depressed pits on segments 1 and 2; palpus formula 1.0: 0.9: 1.1: 1.3 ( Fig. 9 ). Antenna incomplete in the specimens studied; scape subcylindrical and pedicel subspherical; basal flagellomeres pyriform, not eccentric ( Fig. 8 ); ascoids lost. Wing ( Fig. 10 ): Sc complete; sc-r complete; R 5 complete at base; r-m and m-cu absent, radial fork apical to medial fork; CuA 2 ending approximately at the same point as medial fork. Male terminalia ( Figs 11–12 ): hypandrium and gonocoxites fused dorsally; posterior arms of gonocoxite subrectangular in dorsal view with acute apex, 8.8 times the length of gonostylus, convergent, with feathered bristles on entire surface; gonostylus present, blade-shaped, with truncate apex; cercus teardrop-shaped in ventral view; epandrium narrow; cercus teardrop-shaped; apex of hypoproct triangular, with microtrichia; pair of lobes half the length of aedeagal complex; ejaculatory apodeme long, 0.9 times the length of gonocoxal arm.

Etymology. The Latin epithet plumatus (= feathered), refers to the presence of evident branched bristles on the posterior arm of gonocoxite.

Distribution. Brazil, state of Amazonas: Manacapuru, Purupuru.
