THE SYSTEMATIC POSITION OF JEMB_RA_NA DISTANT (HOMOPTERA, APHROPHORIDAE )
Liang Aiping (.The Entomological Museum, Northwestern Agricultural University)
In the present paper comparisons are made through analysis of charactcrs with cLiuistic taxononiic method of the external characters, main male .renital structures and biological features of Jembrana Distant. Ctovfa SUil of the family Aph rophoridae serves as the out-group.Jembrana exhibits a large number of characters (both apornorphic and p'esiomor phic) common to tall aphrophorids. This shows that Jembrana has a crrmion ancestor with all aphrophorids. The Jembrana and Aphrophora Germar of the Aphrophoridae possess many synapomorphies in common and consequently together they form a monophyletic group derived from a common p-rimitive aphrophorid ancestor. But, compared with Aphrophora, Jembrana further exhibits many derivative apomorphies and a few primitive plesiomorphies. The genus Jembrana seems to be more advanced in systematic position than the genus Aphrophora because of its being provided with more aciaptative mechanisms and because of the recency of branching forth from the common ancestor.
