Fletcher, Murray J. & Zahniser, James N., 2008, The first record of Goniagnathini from Australia with description of four new species of Goniagnathus Fieber (Hemiptera: Cicadellidae: Deltocephalinae), Zootaxa 1692, pp. 43-54 : 49

Goniagnathus sp.

( Figures 26–28 )

Material examined: 1 male, 36km NNE of Neale Junction, WA, 28.03S 128.02E, 18–20.ix.1982, B. Hanich & T.F. Houston, 471–4 ( WAM)

Notes: The single male listed here is similar to G. c e n t r a l i s in most structures of the male genitalia but differs in the shape of the subgenital plate which has a broadly emarginate posterior margin ( Figure 26 ), and in the apex of the aedeagus ( Figures 27, 28 ) which has the subapical serrations laterally rather than anteriorly. The specimen is dark chocolate brown with pale spots which further differentiates it from G. centralis but additional specimens are needed to confirm its novelty.
