Comparison to other known species of Becquartina

Based on all the known species of Becquartina a succinct descriptions for each species are provided below:

1. Body velvety black except for the yellow pronotal margin and dull yellowish ochraceous scutellar ribs. Forewing greyish yellow with black veins and darker suffusion along venation. Straight transverse fascia near the centre completely cross the forewing. From the base of costal margin to the node and claval area orange yellow. Hindwing apical area darker than forewing and basal half orange yellow......................................................... B. decorata ( Kato, 1940)

2. Body completely black except the pronotal margin and scutellar ribs which are brilliant yellow. Blackish-yellowish broad forewings have contrasting yellow straight transverse fascia near the centre which completely cross the forewing. From the base of costal margin to the node and claval area bright yellow and so is the basal half of the hindwing. Two line-like unbroken depression in the sub-external part of the anterior femur.................................... B. electa ( Jacobi, 1902)

3. Body completely black except the pronotal margin and posterior lateral lobes which are natural orange. Forewing fuscous except the extreme base including basal cell, costal area, costal vein, anterior margin of radial area and claval area which is neutral orange. A broad orange transverse fascia run across the forewing from the apical portion of the radial area to the hind margin. The basal half of the hindwing orange. Black veins of wings margined with greyish black which gradually diffuses................................................................................ B. bifasciata ( Chen, 1943)

4. Big cicada, entire body is matte black. Pronotal collar entirely yellowish brown. Broad forewing completely yellowish brown with very narrow continuous yellow transverse fascia and yellow and brown claval area. Hindwing completely velvety black.............................................................................. B. bleuzeni Boulard, 2005

5. Similar to B. electa but smaller. The orange-yellow basal spot of forewing reduced, doesn’t touch the base and radial cells. No black stripes along the veins. Two deep and wide depression in the sub-external part of the anterior femur.......................................................................................... B. ruiliensis Chou & Yao, 1985

6. Pronotum collar hemmed with yellowish brown and red. Dark forewing ribbed with red, and bright red costa and two yelloworange fasciae, one wide post-internodal fascia and another basal fascia containing the clavus and large part of cubital cell. Basal half of the hindwing white and rest of the apical area is yellowish brown. Hindwing variable in colour, the basal half may be dark red or tinged with orange or very reduced to non-existent or even the entire hindwing may be chestnut in colour................................................................................. B. versicolor Boulard, 2005

7. Body black and brown dorsally and matte black ventrally. Forewing matte brown with two fasciae. Forewing veins red but at both the fascia, veins are pale greenish, making the fascia undivided. Broad post-internodal transverse fascia of forewing runs from the costa to the hind margin without joining, oblong spindle shaped broad at the centre and narrow at both ends. Basal fascia covers entire clavus, more than half of cubital cell and the trace of it at the base of both medial cell and radial cell. Sexually dichromatic. Basal one third of hindwing pale and apical two third is matte black with pale spots from 2 nd to 5 th apical cells.................................................................................. B. bicolor sp. nov.
