Measurements. Body length: male 3.7 – 4.5 mm ( 6.6 – 7.6 mm including wings) (N=2); female 4.3 mm ( 7.4 mm including wings) (N=1).

Diagnosis. Labium long, reaching the posterior margin of the pygofer ( Fig. 6 A). Periandrium with one long, sinuous spine on right side, with apex curved anteriorly, and two long spines on left side ( Figs 8 A – C); aedeagus with three spines ( Figs 8 A, C). Anal tube (segment X) subpentagonal in dorsal view.

Description. Coloration. General body color brown with yellow regions ( Fig. 6 A). Median and lateral regions of frons with two broad black spots, extending from lateral ocellus to antennae ( Figs 6 B, C). Forewing: basal half brown, apical half hyaline, with white regions: long, white, transverse band at apex of Postcostal cell extending to Median cell; small white diffuse spot within clavus region; ir cross-vein dark brown; dark brown triangular spot at apex of C1a cell; dark brown rounded spot in basal half of C3 cell; narrow dark brown stripes on median region of CuA2 vein extending to icu cross-vein ( Fig. 6 F). Pterostigma yellow ( Fig. 6 F). Legs yellow, except apex of procoxa dark brown, narrow brown stripe on posterior margin of profemur, ventral region of protibia dark brown, narrow brown stripe on anterior and posterior margins of mesofemur and ventral region of mesofemur and ventral region of the mesotibia dark brown ( Fig. 6 A). Abdomen: tergites brown; sternites whitish yellow; pygofer, anal tube and gonostyli yellowish brown.

Head: vertex not recognizable ( Fig. 6 D); frons with median carina strongly elevated ( Figs 6 B–D), lateral keels strongly produced ( Figs 6 B, D), and lateral carinae strongly directed obliquely laterally ( Fig. 6 C); median carina of the clypeus present ( Fig. 6 C); labium long, reaching the posterior margin of the pygofer ( Fig. 6 A); scape short, pedicel oblong (about three times longer than scape) ( Fig. 6 C). Thorax: pronotum with anterior margin truncated, median carina absent, lateral carinae moderately diverging towards tegula, and posterior margin with angled indentation; mesonotum with median and lateral carinae present, weakly marked ( Fig. 6 D). F orewing: m-cu cross-vein absent; icua cross-vein absent ( Fig. 6 F).

Male terminalia ( Figs 7 A–F; 8 A–F): Pygofer posterior margin with short triangular protuberance on each side in the middle region ( Figs 7 A–C); medioventral process robust, conical, in lateral view, with posterior margin triangular in ventral view ( Figs 7 A, B, D). Gonostyli symmetrical, widening in the apical third, curved upward with pointed apex in lateral view, apically divergent in dorsal view ( Fig. 7 F). Phallic complex robust, with almost straight periandrium bearing four retrorse spines in the apical half, spines as follows ( Figs 8 A–C): one slender, elongated spine curved ventrally on left side (S1) ( Figs 8 A, B); one long spine curved posteriorly on left side, near the apex (S2) ( Figs 8 A–C); one slender, elongated spine directed anteriorly, on dorsal margin (S3) ( Figs 8 A, B); one long and sinuous spine on right side, apex curved anteriorly and dorsoventrally, flattened in dorsal view (S4) ( Figs 8 A–C). Aedeagus cylindrical with membranous regions in the apical half and three spines ( Figs 8 A–C), spines as follows: two short, slender, almost straight spines of different sizes, one inserted near base (S5) ( Figs 8 A–C), approximately twice length of spine inserted in the apical half (S7) ( Figs 8 A–C); one long, robust, almost straight, directed anteriorly in the basal half (S6) ( Figs 8 A–C). Anal tube (segment X) robust, subpentagonal in dorsal view, ventral margin abruptly folded down anteriorly at apex in lateral view ( Figs 8 D, E), apex truncated in posterior view ( Fig. 8 F).

Female terminalia ( Figs 9 A–H). Pygofer elongate, symmetrical, about three times longer than the greatest width in posterior view ( Figs 9 A–C). Gonapophysis VIII (first valvula) slender, slightly curved upward, with small spiniform projections at basal two-thirds ( Figs 9 D, E). Gonapophysis IX (second valvula) tapered towards apex, with numerous small, rounded projections (rp) on the inner margin ( Figs 9 F, G). Gonoplac (third valvula) tapered towards apex, rounded apex in lateral view, covered with small spiniform projections (sp) ( Fig. 9 H). Anal tube (segment X) cylindrical in lateral view ( Fig. 9 A).

Distribution. Brazil ( Amazonas) ( Fig. 10).

Etymology. In posthumous tribute to Dr. Francisco Filho Silva from the Instituto Federal de Educação, Ciências e Tecnologia do Tocantins (IFTO), Campus Araguatins , Brazil, for his contribution to the academic education of the first author, as an excellent teacher, friend, and researcher.

Taxonomic notes. Noabennarella franciscoi sp. nov. is externally very similar to Noabennarella paveli Holzinger, Holzinger & Egger.However , N. franciscoi sp. nov. can be distinguished from the latter by the periandrium bearing one long, sinuous spine on the right side, with the apex curved anteriorly; two long spines on the left side; and aedeagus with three spines. In contrast, N. paveli differs by the periandrium having one short spine on the right side, with apex curved ventrally; two spines on the left side (one long and one short near the apex); and aedeagus with two spines.
