Tribe Platyjassini Evans, 1953 View in CoL

Platyjassini Evans, 1953: 113 View in CoL (type genus: Platyjassus Evans, 1953 View in CoL ).

Description

HABITUS. Medium-sized to large (4.9–19.0 mm) pale yellow (green in life) or brown leafhoppers, with or without red, yellow or brown markings. Body moderately to strongly depressed ( Figs 1–3 View Fig View Fig View Fig ).

HEAD. With crown flat to slightly convex, usually produced, with two or more transverse carinae delimiting crown-face transition ( Figs 23 View Fig D–F). Ocelli on crown well separated from anterior margin and eyes. Face ( Figs 23 View Fig D–E) flattened to slightly convex; antenna inserted near anterodorsal corner of eye, shorter than head width; antennal ledge oblique, sharply carinate but not concealing antennal base, or amalgamated with marginal rim of crown; lateral frontal sutures absent or extended only to dorsal margin of face; gena slightly to strongly emarginate below eye, partially to completely concealing proepisternum; lorum flat, not extended to lateral margin of face; anteclypeus flat to slightly convex, distinctly broadened distally; rostrum short, not extended beyond middle coxae.

THORAX. Pronotum ( Figs 1–3 View Fig View Fig View Fig ) with transverse striations indistinct to well developed, lateral margins carinate and slightly to strongly divergent posterad of eyes, usually wider than head. Forewing venation ( Fig. 23G View Fig ) including at least one s, two r-m and three m-cu crossveins, appendix well developed, much wider than inner apical cell, extended to or near wing apex. Hindwing venation complete, with R4+5 and M1+2 partially ( Fig. 23H View Fig ) to completely confluent ( Fig. 23I View Fig ). Front femur with AM1 well developed, other setae of AM poorly differentiated or absent; row IC uniseriate or with setae scattered near apex; AV usually with several long, stout setae; tibia cylindrical or with dorsal surface somewhat flattened, row PD with widely spaced macrosetae; AD weakly differentiated; ventral rows moderately to well differentiated. Middle femur usually with several widely spaced macrosetae in AD and PD. Hind femur macrosetal formula usually 2+ 2+1, with penultimate pair close-set; supernumerary macrosetae sometimes present; tibia with all macrosetal rows well differentiated and extended for nearly full length of tibia, PD macrosetae more numerous and usually slightly longer than in AD; tarsomere I with dorsoapical pair of macrosetae, plantar rows variably developed, pecten with four or more platellae.

ABDOMEN. Male abdomen with 2S apodemes usually well developed, capitate ( Fig. 21E View Fig ); sternite VII enlarged, posterior margin truncate, slightly produced or slightly emarginate, concealing at least basal half of subgenital plates with genital capsule in resting position. Pygofer ( Fig. 21F View Fig ) broadly fused to valve, base well sclerotized dorsally, lobes with numerous scattered macrosetae in distal half, with or without appendages. Subgenital plates ( Fig. 21G View Fig ) separate to base, freely articulated to valve, narrow at base, broadened toward middle, then tapered to slightly compressed apices, usually extended to or near pygofer apex, with or without macrosetae, usually with some long, fine setae along dorsolateral margin. Style ( Fig. 19H View Fig ) narrow and sinuate basally, with short apodeme and elongate apophysis often bearing denticuli ventrally. Connective ( Figs 19H View Fig , 20H View Fig ) with median anterior lobe variably developed, articulated to aedeagus. Aedeagus with dorsal apodeme usually well developed, shaft usually curved dorsad, with or without processes. Ovipositor with dorsal sculpturing of first valvulae strigate ( Fig. 16A View Fig ) or (rarely) imbricate-areolate ( Fig. 17Q View Fig ); second valvulae usually broad distally with dorsal margin serrate distally ( Fig. 16R View Fig ), rarely narrow with two widely spaced dorsal teeth ( Fig. 16C View Fig ).

Remarks

As mentioned by Evans (1953), Platyjassini are superficially similar to members of the endemic New World iassine tribe Gyponini in having the crown usually well delimited and flattened, with the ocelli on the crown and well separated from the anterior margin and eyes. The two tribes also have a similar structure of the male and female genitalia, forewing venation and leg chaetotaxy. Platyjassini differ from Gyponini in having the anteclypeus broadened apically, the forewing appendix much wider than the inner apical cell, and the hindwing with veins R4+5 and M1+2 partially to completely confluent.
