Species descriptions
Paratettix amplus
male and female: costa frontalis inter antennas arcuato-producta, ab ocello ima basi excepta tota sulcata; vertex carina ad apicem producta postice obliterara instrucus, antice utrinque impressus, margine antico recto, angulis rotundatis; oculi supra verticem paulo elevati; pronotum femora valde suerans ad humeros arcuato-ampliatum, inter dilatationem et carinam mediam utrinqque carina abbreviata instructum, ab antico visum curvum, postice depressum, margine posticotruncatol carina media perfect, gracilis, integra, ad sulcum posticum vix consicue curva, propre meginem anticum subito depressa et olbiterata; lobus infero-posticus acuminatus; elytra ovali-oblonga apice rotundato; alae longae valde caudatae; carina femorum anticorum integra haud undata; articulus primus tarsorum posticorum tertio brevior. Fusco-niger, partim pluis minusve dilutior; tibiae posticae corneae; pronotum supra utrinque plaga nigra.
Paratettix argillaceus
P. proecedenti simillimus sed intervallo oculorum distincte latiore, latitudine oculorum, fastigio antrorsum non sensim angustato differt.
Paratettix albescens
This species appears identical or closely related to Paratettix histricus.
Paratettix femoralis
Pronotum, especially in the female, is somewhat roof-shaped, with a median keel which continues to the anterior edge. Sydney.
Paratettix australis
This is very similar to Paratettix femoralis in that the median carina continues to the anterior edge of the pronotum, but it is much broader between the eyes, just as wide as the width of the eyes. The median carina is lower and somewhat bent anterior to the cross slit.
