Nannicerus gracilis Maldonado-Capriles, 1977: 605 View in CoL ( Figs. 1–14 View FIGURES 1–4 View FIGURES 5–14 ).

Type locality. Demerara, Guyana .

Diagnosis. Based on material collected in Manaus. Yellow macula of forewing reaching costal margin ( Fig. 5 View FIGURES 5–14 ); UFS apex not reaching correspondent ocellus ( Fig. 2 View FIGURES 1–4 ); femora entirely yellow ( Fig. 4 View FIGURES 1–4 ); apodeme of sternite II longer than sternite II ( Fig. 6 View FIGURES 5–14 ); pygofer with a ventral basal projection directed posterodorsally ( Fig. 7 View FIGURES 5–14 ); connective without apical longitudinal keel ( Figs. 11 View FIGURES 5–14 ); dorsal apodeme of aedeagus with globular apex ( Figs. 13 View FIGURES 5–14 ); aedeagus shaft with small posterior spines ( Figs. 13–14 View FIGURES 5–14 ); laterobasal process of anal tube well developed, with apex bifurcate, dorsally curved ( Fig. 7 View FIGURES 5–14 ).

Material examined. “ BRASIL, Amazonas , Manaus, ZF-2, \ km-14, 2º35’21’’S – 60º06’55’’W, \ 1–15.v.2018, Malaise gde [grande], 16 m alt [altura], \ lado poente, J.A.Rafael —Rede BIA”, 1♂ INPA GoogleMaps , 1♂ MNRJ ; idem, “ 8 m alt [altura], \ lado poente, J.A.Rafael —Rede BIA”, 1♂ MZSP ; idem, “ 8 m alt [altura], \ lado nascente, JARafael—Rede BIA”, 1♂ MNRJ ; idem, “ 24 m alt [altura], \ lado poente, J.A.Rafael —Rede BIA”, 1♂ INPA ; idem, “ 24.xii.2017 08.i.2018, Malaise gde [grande], 8\ m alt [altura], lado poente, J.A.Rafael ”, 1♂ MZSP ; idem, “ 16 m alt [altura], lado poente, J.A.Rafael ”, 1♂ INPA ; idem, “ 25.ii–13.iii.2018, Malaise gde [grande], 8m \ alt [altura], lado poente, J.A.Rafael ”, 1♂ INPA ; idem, “ 16m \ alt [altura], lado poente, J.A.Rafael ”, 1♂: MNRJ .

Measurements (mm). Males (n=9), total length (to apex of forewing): 3.81–4.35; median length of crown: 0.23–0.35; length of crown close to eyes: 0.25–0.31; width of head: 1.58–1.65; width of crown between eyes: 0.79–0.83; length of pronotum: 0.48–0.56; length of scutellum: 0.75–0.83; width of pronotum: 1.32–1.35; width of scutellum: 1.01–1.14; length of frons: 0.97–1.56; width of frons between eyes: 0.80–1.24; distance between ocelli: 0.44–0.65; ocellocular distance: 0.14–0.22; length of clypeus: 0.31–0.50; apical width of clypeus: 0.25–0.35; basal width of clypeus: 0.22–0.32.

Remarks. Illustrations of the head in dorsal and frontal views, pronotum, scutellum, forewing, genital capsule of female and male terminalia of type-material were provided by Maldonado-Capriles (1977 a). Specimens collected in Amazonas, Brazil have the anterior region of head somewhat triangular in dorsal view ( Figs. 1, 3 View FIGURES 1–4 ) (rounded in Guyanan specimens); veins of apical cells are brown and well defined in all specimens ( Fig. 5 View FIGURES 5–14 ) (red tinged or poorly defined in Guyanan specimens); connective apex distinctly truncated ( Fig. 12 View FIGURES 5–14 ) (rounded in Guyana specimens); sternite II with a pair of subtriangular apodemes with rounded apex, slightly curved dorsally, apodemes longer than sternite II ( Fig. 6 View FIGURES 5–14 ).

Nannicerus gracilis is the smallest species, with males reaching 3.81–4.35 mm (males are longer than 5.21 mm in N. curica sp. nov. and longer than 6.76 mm in N. grandis sp. nov.). It can be further distinguished from the other two species by: color pattern of crown and frons orange ( Figs. 1–4 View FIGURES 1–4 ) (black in N. curica and N. grandis ); anal tube with a laterobasal hook shaped process longer than in other two new species ( Fig. 7 View FIGURES 5–14 ); pygofer with a basal ventral projection ( Fig. 7 View FIGURES 5–14 ); connective with apophysis apex truncated ( Figs. 12 View FIGURES 5–14 ) (rounded in the other two new species); and aedeagus shaft with spines in posterior apical region ( Figs. 13–14 View FIGURES 5–14 ).

Bionomy. Specimens of the N. gracilis in Brazil were collected at heights of 8, 16, and 24 m at ZF-2 tower in December/January, February/March, and May.
