Membracis latifasciata Sakakibara and Evangelista sp. nov. ( Figures 18, 24 View Figures 24–26 , 27 View Figures 27–29 )
Diagnosis
Pronotum black, with broad yellow longitudinal band extended from the anterior margin to near the tip of posterior process, delimited superiorly by the sutural line and inferiorly by the lateral margins; in lateral view, pronotum fusiform, highly elevated above humeral angles and gradually descending towards apex of posterior process.
Measurements
Male/female (mm): total length 10.25/9.87; length of pronotum 8.50/8.25; length of tegmina 7.50/7.75; width of head 2.00/1.93; width between humeral angles 2.56/2.50; length of head 1.37/1.43.
Description
Male. Pronotum black; broad longitudinal yellow band extended from anterior margin above the head to near tip of posterior process, delimited superiorly by the sutural line and inferiorly descending from above the head to lateral margins, passing over humeral angles. Head black, eyes and ocelli castaneous. Tegmina dark, opaque; hind wings hyaline, slightly amber. Ventral surface of head, thorax, abdomen and legs concolorous with pronotum, except for brown tarsi.
Head approximately as wide as long, finely punctuate and pubescent, especially above epistomal suture; vertex weakly convex, lateral borders very slightly curved anteriorly; epistomal suture indistinctly grooved; superior margin inconspicuously sinuous; ocelli prominent, closer to eyes than each other; suprantennal ledges somewhat straight, foliaceous, vertical, almost parallel to each other; postclypeus diamond shaped, as long as wide, extended half its length beyond lower margins of vertex, apex truncate, covered with dense and shining pubescence.
Pronotum finely punctuate, sparsely pubescent; highly elevated above humeral angles, almost twice as long as high and then gradually arcuate to apex; in lateral view, fusiform, distinctly projected for a short distance anterior to head, anterior lobe rounded and weakly projected downwards, not reaching the level of ocelli; humeral angles obsolete; apex of posterior process acute, reaching distal angle of fifth apical cell of tegmina. Sutural line uniformly arcuate, almost parallel to dorsal margin.
Tegmina with veins R, M and Cu divergent at base; one discoidal and five apical cells; transverse veins s, r-m and 2 m-cu present; veins distinct, weakly punctuate throughout.
Genitalia closely resembling that of other Membracis species : aedeagus U-shaped, shaft directed vertically, anterior surface denticulate apically; styles slender, apical hook of shank curved, apex truncate with sharp edges, the ventral edge more pronounced; gonopore large, eliptical, subapical on posterior surface, membrane not produced.
Female. Identical to male, slightly smaller.

Remarks
Membracis latifasciata sp. nov. strongly resembles M. fusifera Walker and also M. foliataarcuata (DeGeer) regarding the shape of pronotum and the lateral yellowish bands. In the former, the yellow band is more or less fusiform and does not reach the anterior margin; in the latter species, on the other hand, the pronotum is more expanded, regularly rounded and the yellow band is much narrower, extending from the anterior margin to near the apex. In this new species, the yellow area of pronotum is far more extensive than the black area.
