Nannicerus grandis View in CoL sp. nov.

( Figs. 31–46 View FIGURES 31–34 View FIGURES 35–46 )

Type locality. ZF-2, Manaus , Amazons State, Brazil .

Diagnosis. The yellow macula of forewing does not reach costal margin ( Fig. 35 View FIGURES 35–46 ); UFS apex reaching correspondent ocellus ( Fig. 32 View FIGURES 31–34 ); femora with median black macula ( Fig. 34 View FIGURES 31–34 ); apodeme of sternite II shorter than sternite II ( Fig. 36 View FIGURES 35–46 ); pygofer without a ventral basal projection ( Fig. 37 View FIGURES 35–46 ); connective with an apical longitudinal keel ( Fig. 41 View FIGURES 35–46 ); dorsal apodeme of aedeagus with pointed apex ( Fig. 43 View FIGURES 35–46 ); aedeagus shaft with lateral spines from base to gonopore ( Figs. 43–45 View FIGURES 35–46 ); laterobasal process of anal tube short, with pointed apex ( Fig. 37, 46 View FIGURES 35–46 ).

Measurements (mm). Holotype male, total length (to apex of forewing): 6.89; median length of crown: 0.25; length of crown close to eyes: 0.36; width of head: 2.57; width of crown between eyes: 1.35; length of pronotum: 0.83; length of scutellum: 1.36; width of pronotum: 2.15; width of scutellum: 1.86; length of frons: 1.93; width of frons between eyes: 1.35; distance between ocelli: 0.68; ocellocular distance: 0.28; length of clypeus: 0.74; apical width of clypeus: 0.38; basal width of clypeus: 0.46; length of forewing: 5.87. Male (n=1). total length: 6.76; median length of crown: 0.30; length of crown close to eyes: 0.36; width of head: 2.51; width of crown between eyes: 1.30; length of pronotum: 0.87; length of scutellum: 1.27; width of pronotum: 2.14; width of scutellum: 1.82; length of frons: 1.89; width of frons between eyes: 1.30; distance between ocelli: 0.67; ocellocular distance: 0.27; length of clypeus: 0.73; apical width of clypeus: 0.37; basal width of clypeus: 0.42.

Coloration. Male: Color pattern of body as in the generic description, except for: eye with red-tinged internal area ( Figs. 31–34 View FIGURES 31–34 ). Color pattern of crown, frons, lorum, gena, and clypeus as in N. curica sp. nov. ( Figs. 31–33 View FIGURES 31–34 ). Pronotum with three black irregular macula ( Figs. 31, 33 View FIGURES 31–34 ). Scutellum as in N. curica sp. nov. (Figs. 31,33). Forewing with black macula on inner anteapical cell, apical region of 3rd and 4th apical cells, and at base of appendix ( Fig. 35 View FIGURES 35–46 ); irregular macula which can vary from light yellow to red on clavus ( Fig. 35 View FIGURES 35–46 ).

Description. Head with anterior margin of crown rounded ( Figs. 31 View FIGURES 31–34 ); median length shorter (0.3x) than length close to eyes; approximately 0.3x pronotal length. UFS as in N. curica sp. nov. ( Fig. 32 View FIGURES 31–34 ). Frons 1.43x longer than wide between eyes; distance between ocelli approximately 2.4x longer than ocellocular distance. Clypeus approximately 0.2x wider basally than apically. Rostrum long, posteriorly crossing metacoxa ( Figs. 32, 34 View FIGURES 31–34 ). Pronotum as in N. curica ( Fig. 31, 33 View FIGURES 31–34 ). Scutellum approximately 0.2x longer than wide. Combined length of crown and pronotum approximately 0.4x shorter than length of scutellum. Apodemes of sternite II with a distinct triangular projection on basal region, shorter than sternite II, and anterior region somewhat straight ( Fig. 36 View FIGURES 35–46 ).

Male terminalia. Pygofer as in N. curica sp. nov. ( Fig. 37 View FIGURES 35–46 ). Subgenital plate 1.5x longer than pygofer. Connective with an apical longitudinal keel ( Fig. 41 View FIGURES 35–46 ). Style as in N. curica ( Figs. 40, 42 View FIGURES 35–46 ). Dorsal apodeme of aedeagus with pointed apex ( Fig. 43 View FIGURES 35–46 ); shaft as in N. curica , except for pointed apex ( Figs. 43–45 View FIGURES 35–46 ). Anal tube with laterobasal process short, triangular, pointed apex, directed posteroventrally ( Fig. 37, 46 View FIGURES 35–46 ).

Female unknown.

Etymology. From the Latin grandis = large, great, referring to the size of this species.

Remarks. N. grandis sp. nov. (6.76–6.89 mm) are larger than N. gracilis (3.81–4.35 mm) and N. curica sp. nov. (5.21–5.37 mm). Nannicerus grandis can be easily recognized based on: apodemes of sternite II shorter than sternite II ( Fig. 36 View FIGURES 35–46 ); connective shaft with apical longitudinal keel ( Fig. 41 View FIGURES 35–46 ); dorsal apodeme of aedeagus with pointed apex ( Fig. 43 View FIGURES 35–46 ); laterobasal process of anal tube with pointed apex (37, 46).

Bionomy. Specimens were collected at heights 8 and 16 m at December/January, and May.
