本文记述并图示了采自西藏中国地区的一种新的稻飞虱分类群--Garumnella Bella GenN.n.，sp.n.，包括成虫和卵的外部形态以及雌雄生殖器的结构。将新属与Garumna Melichar和Paragarumna Muir进行比较，得到Paragarumna(Syn.n.)被列为Garumna的一个初级异名，并有两个新组合，即Garumna Passolappa(Muir)com.n。和Garumna Melichari Baker Comb.给出了Garumna种的Rev.新位置记录。对一对交配的新属的生殖器和卵子的形态进行了观察。女性有腹侧硬化性后阴道，形成扭转沟，前部有异常长的膜状阴道和增大的共同输卵管。在交配过程中，脊翼和扭槽看起来紧密相连，这可能有助于保持交配位置。在法氏囊的交界处可以观察到泡状突起。
The new planthopper taxon, Garumnella bella gen.n., sp.n., from Xizang, China, is described and illustrated, including external morphology of adult and eggs and structures of the male and female genitalia. The new genus is compared with Garumna Melichar and Paragarumna Muir, resulting in Paragarumna (syn.n.) being placed as a junior synonym of Garumna, with two new combinations, i.e. Garumna pseudolepida (Muir) comb.n. and Garumna melichari Baker comb. rev. New locality records for Garumna species are given. The morphology of the genitalia and egg of a copulating pair of the new genus is investigated. The female has a ventrally sclerotized posterior vagina forming a torsion groove, an unusual long membranous anterior vagina and an enlarged common oviduct. During copulation both the aedeagus and the torsion groove appear tightly interlocked, which may help to maintain the copulatory position. The aedeagus is observed in the bursa copulatrix.
