From Vivek:

I am thrilled to share with you the latest development in our research endeavors here in India. We have recently uncovered an astonishing new cicada species from the genus, marking its inaugural appearance in India. This significant discovery was made independently within the mysterious forests of Garo Hills and Ri Bhoi district, igniting a sense of wonder in the realm of biodiversity exploration and shedding light on the untapped potential of Meghalaya’s diverse ecosystems.

As you are aware, cicadas in India have been a long-standing subject of neglect, with studies stagnating since the early 20th century. Despite boasting the world’s highest generic diversity of cicadas, their biology remains largely unexplored within India. With the unveiling of four new species in Meghalaya (including this one), alongside four additional additions to India’s cicada diversity since 2020, these forests continue to unveil new marvels.

Here is a link to the paper by Vivek Sarkar, Rodeson Thangkhiew, Cuckoo Mahapatra, Pratyush P. Mohapatra, Manoj V. Nair, and Sudhanya R. Hajong: Discovery of the cicada genus Becquartina Kato, 1940 (Hemiptera: Cicadidae: Cicadinae) in India with the description of a new species from Meghalaya.

This is a photo of one of my displays at home. Some of the specimens aren’t in the best shape, but it is good enough to distinguish the species.

Angamiana floridula, Becquartina electa, Gaeana cheni, Gaeana festiva, Platypleura mira, Tacua speciosa, Tosena albata, Tosena melanoptera, Tosena paviei, and Trengganua sibylla are featured in the image.

The “Butterfly Cicadas”

The cicadas belonging to the tribe Gaeanini (Ambragaeana sp., Gaeana sp., and Becquartina sp.)1 are among the world’s most beautiful cicadas. These cicadas have broad, multicolored wings. Their wings beat slowly rather than vibrate quickly, allowing them to flutter like butterflies. Michel Boulard calls them “Butterfly Cicadas” 2. Watch the video of a Gaeana festiva in flight:

Behold the beautiful “Butterfly Cicadas”:

Distinguishing features: Gaeana festiva come in an amazing variety of color variations. Colors include orange, yellow, white and pale green; fore and hind wings are often different colors as well. G. festiva, as Michel Boulard speculates, might be a periodical cicada, as it emerges in very large numbers 2. They might he proto-periodical as well.

Habitat: India, Southeast Asia3
