  Type genus:

   Trocnada Walker, 1858.

Introduction

This tribe originally included only the endemic genus Trocnada Walker with three species, all associated with the tree genus Eucalyptus L'Héretier (Myrtaceae). The oriental genus Trocnadella Singh-Pruthi was included in the tribe by Oman et al. (1990) without any justification and it was later removed by Dai & Dietrich (2012). Krishnankutty et al. (2016) transferred the genus Thalattoscopus Kirkaldy into Trocnadini so it now contains two genera, one endemic Australian and the other distributed mainly in New Guinea and neighbouring islands with three species in Australia.

Diagnosis

Medium-sized stramineous, brown or red leafhoppers; head short, crown poorly or not delimited, ocelli on face; forewing appendix well developed but not extended around wing apex; hindwing veins R4+5 and M1+2 confluent distally; male subgenital plates elongate, only partially concealed by pregenital sternite; female first valvulae with dorsal sculpturing strigate; second valvulae with two to three prominent widely spaced dorsal teeth.

Morphological synapomorphies supporting the monophyly of this group include the absence of macrosetae on the front femur, presence of a well-developed dorsal apodeme on the aedeagus, and the short, falcate male pygofer appendage (Krishnankutty et al. 2016).

Introduction

This genus was synonymised with Batracomorphus Lewis by Linnavuori & Quartau (1975) but reinstated by Knight (1983) who demonstrated that it was distinct. The genus was reviewed by Knight & Webb (1986) who recognised 21 species all of which are restricted to New Guinea, neighbouring island groups and northeastern Australia. Three species are recorded in Australia. The genus includes species in New Guinea which are recognised pests of coffee, Coffea arabica L. (Rubiaceae). The genus was transferred into the tribe Trocnadini by Kriahnankutty et al. (2016).

"Very similar to Bythoscopus, Germ. (=Macropsis, Auctt.), but frons, clypeus and genae anastomosed or only obsoletely sutured off. Postmargin of eyes beneath, emarginate. Apical margin of head widely rounded. Ocelli distant about two and a half times as far from each other as from the eyes. Vertex very short, seven or eight times as wide between the eyes as long, about twice as wide as the eyes together, acutely margined basally. Antennal ledge truncate. Pronotum and scutellum very distinctly transversely striated, pronotum at base slightly wider than the eyes, lateral margin somewhat rounded" (Kirkaldy 1905).
