Rhotanella

Rhotanella is a small genus of planthoppers from the family Derbidae, tribe Rhotanini, with 8 species.

The species are found in the Philippines, Indonesia, New Guinea, the Solomon Islands and southern China.

The remaining forewing venation is similar to that found in the genera Alara, Dichotropis, Levu and Rhotana.

[1][2][3] Other features of Rhotanella include a mostly brownish colour of the forewings, typically with many veins lined with white spots.

It includes 4 species (R. bipunctata, R. lautereri, R. novemmaculata and R. punctuvenosa) which are found in the Philippines, the island of Sulawesi (Indonesia) and southern China.

[4][6][2][7][3] Apart from the approximately rectangular outline of the head in profile, the forewings have a series of black marks on the costa near the wing base.

It is assumed that the nymphal stages live in decaying organic matter like other derbids, feeding on fungi.

[6][2][3] Two species of Rhotanella (R. lucida and R. punctovenosa) had been already described under the genera Rhotana and Levu before Fennah's description of the genus.

[2] Taken the unusual forewing shape, venation and colouration, the separation of Rhotanella from Rhotana and Levu seems to be fully justified.
