Diagnosis
Green sharpshooters with dark broad longitudinal stripes; aedeagus, in lateral view, directed posterodorsally, almost straight from curvature at base, with pair of dentiform processes on dorsal portion; paraphysis (i.e. with a single ramus) directed posteriorly.
Comment
The paraphysis (i.e. with a single ramus) is an autapomorphy of
S. interruptula
(

)
.
Type locality.
‘Chapada’,

External morphology
Head (
Figure 3
) moderately produced anteriorly, median length of crown about 1/2 interocular width and 1/3 transocular width; anterior margin narrowly rounded in dorsal view; ocelli located behind anterior eye angles, each closer to adjacent anterior eye angle than to median line of crown, situated at pair of slight concavities. Pronotum (
Figure 3
) with width approximately equal to transocular width of crown; lateral margins convergent anteriorly; dorsopleural carinae complete and oblique; disc smooth. Fore wings (
Figure 3
) opaque; membrane including all of apical cells, extending anteriorly along costal margin as far as basal half of wing. Hind legs with femoral apical setal formula 2:1:1; length of first tarsomere greater than combined length of two more distal ones.
Coloration
Background colour of crown, anterior third of pronotum, and mesonotum light green; remainder of dorsum dark green (
Figure 3B
). Crown with dark brown transversal stripe anterior to ocelli, forked at ends, and dark brown transversal stripe along posterior margin with projections attaining ocelli; dark brown line on median line of crown linking both transversal stripes (
Figure 3B
). Anterior third of pronotum with dark brown transversal stripe forked at ends, with short anterior branches, posterior branches extending posteriorly as far as mesonotum and returning to pronotum (
Figure 3B
). Mesonotum (
Figure 3B
) with three dark brown maculae: two on basal angles continuous with stripes of pronotum and median one extending from base to scutellar suture. Fore wings (
Figure 3B
) with dark brown stripes on and beside longitudinal veins. Face and ventral body parts yellow; pair of dark brown longitudinal stripes on muscle impressions.
Male genitalia
Pygofer (
Figure 4A
), in lateral view, moderately produced posteriorly; dorsal margin concave; ventral margin approximately rectilinear; apex narrowly rounded; numerous macrosetae from apical half to apex, scattered basally; slender process arising from ventral margin, extending posteriorly as far as apex of pygofer. Subgenital plates (
Figure 4B
) subtriangular, not extending posteriorly as far as apex of pygofer, gradually tapered towards narrow apical portion; macrosetae multiseriate near base, becoming uniseriate towards apex. Styles (
Figure 4C
) slender, without preapical lobe, not extending posteriorly as far as apex of connective; apex obliquely truncate. Connective (
Figure 4C
) Y-shaped. Aedeagus (
Figure 4D
), in lateral view, directed posterodorsally, almost straight from curvature at base; apex acute, with pair of dentiform processes on dorsal portion. Paraphysis (
Figure 4D
) with ramus directed posteriorly, apex acute.

Comparative notes
Scopogonalia interruptula
resembles externally
S. paula
and
S. osteiphera
sp. nov.
(
Figure 11A
) by the green colour and the broad dark brown stripes on and beside the longitudinal veins of the fore wings. However, it is different from these and any other species of the genus because of the single paraphysis (
Figure 4D
), instead of the paraphyses of the other ones.
