Nullana sakakibarai  sp. nov.

( Figs 20–39View FIGURES 20 – 32View FIGURES 33 – 39. 33 – 37)

Diagnosis. Style ( Fig. 30View FIGURES 20 – 32) with blade slightly sigmoid, ventral margin with small tooth at mid-length; apex constricted subapically, curved dorsally with two small tips.

Description. (male) length 8.1mm (n=4), (female) length 8.7mm (n=3). Protibiae PD row with only four setae. Other characteristics as in previous description.

Coloration. Forewing ( Fig. 23View FIGURES 20 – 32) with black spot at base of clavus, anal margin with black maculae only on anterior angle. Other characteristics as in previous description.

Male terminalia. Sternite VIII ( Fig. 24View FIGURES 20 – 32) 1.6 times wider than long; posterolateral angles rounded, posterior margin with small V-shaped notch at middle. Valve ( Fig. 25View FIGURES 20 – 32) 1.5 times wider than long; integument thickening only on anterior margin; posterior margin emarginate. Pygofer ( Fig. 26View FIGURES 20 – 32) 1.6 times longer than maximum height; dorsal margin without process at base; dorsoapical margin approximately straight; ventroapical margin slightly rounded; apex tapered and truncate; macrosetae dispersed on posterior half. Subgenital plate ( Fig. 26View FIGURES 20 – 32) produced posterad almost as far as apex of pygofer; in ventral view ( Fig. 27View FIGURES 20 – 32) 5.8 times longer than wide, with small setae on lateral margin and apex; lateral margins straight and parallel; apex rounded. Connective ( Fig. 28View FIGURES 20 – 32) Y-shaped, twice as long as the basal width; stalk elongated, longer than wide; apex directed ventrally. Style ( Fig. 29View FIGURES 20 – 32), in dorsal view, with outer lobe small and rounded; in lateral view ( Fig. 30View FIGURES 20 – 32), blade elongated and slightly sigmoid, ventral margin not serrated, with small tooth at mid length; apex constricted subapically, curved dorsally with two small tips. Aedeagus ( Figs 31, 32View FIGURES 20 – 32) with preatrium developed; dorsal apodemes weakly developed laterodorsally and rounded; shaft short, lateral margins carinated, with pair of small spinelike latreral subapical processes; apex membranous, bent ventrally with two translucent lobes.

Female terminalia. Sternite VII ( Fig. 33View FIGURES 33 – 39. 33 – 37) 2.0 times wider than long; posterolateral angles rounded, posterior margin with V-shaped notch at middle. Other characteristics as in previous description.

Material examined. Holotype male: " Brasil, PR, Antonina \ Res.[Reserva] Rio Cachoeira \ 25.316°S 48.696°W \ 50m, 20–25.xi.2014 \ Luminosa\ Entomologia UFPR "; Paratypes: 3 ♂, same data as the holotypeGoogleMaps  ; 2 ♀, " Antonina - PR \ Reserva Sapitanduva \ Brasil 16.V.1988 \ Lev.[Leventamento] Ent.[Entomológico] PROFAUPAR\ Malaise"  ; 1 ♀, " Morretes - PR Brasil \ ( IAPAR)\ 18-25.II.1985 \ C.I.I.F. (Malaise)". 

Remarks. Nullana sakakibarai  sp. nov. is most similar to N. gelbana  and N. alena  in having the style with a small tooth on the ventral margin. However in the new species the blade is sigmoid and the small tooth is at about the mid-length of the blade. In the two other species the style is approximately straight. Nullana gelbana  has the small tooth near the apex of the blade and the tooth in N. alena  is near base. Also, in the new species the style apex is constricted subapically, with two small tips, a characteristic not present in other Nullana  species.
