Salinesia gen. nov.

( Figs 1–21 View FIGURES 1–8 View FIGURES 9–21 )

Type species. Salinesia atacamensis sp. nov., here designated.

Diagnosis. Body small (males <2 mm), dorsal side concolorous (male abdomen darker in Kosswigianella and usually in Muirodelphax ). Pronotum with lateral carinae reaching hind margin (lateral carinae of pronotum usually not reaching hind margin in Muirodelphax and Kosswigianella ). Male pygofer without processes, with armature not produced and narrowed due to excavation (armature of pygofer broad, usually produced in Muirodelphax and Kosswigianella ). Phallus curved ventrad. Segment X of male without processes (segment X usually with processes in Koswigianella).

Description. All specimens brachypterous. General body shape oblong, small (<2 mm), more than twice longer than wide; dorsal side concolorous ( Figs 1–6 View FIGURES 1–8 ).

Head. From dorsal view ( Figs 1, 3, 5 View FIGURES 1–8 ) subacute, subequal in width as pronotum. Macrocoryphe ( Figs 1, 3, 5 View FIGURES 1–8 ) longer than wide; lateral margins parallel; anterior side and posterior margin equal or almost equal in width; posterior margin of macrocoryphe straight or slightly notched, reaching eyes before mid-length; coryphe composed of two narrow pentagonal cells enclosed by carinae. Fastigium ( Figs 2, 4, 6 View FIGURES 1–8 ) in lateral view roundly curved. Eumetope in lateral view slightly convex ( Figs 7, 8 View FIGURES 1–8 ), widest near mid-length; inferior margin (at metopoclypeal suture) as wide as superior side (at fastigium); median carina distinct. Rostrum surpassing mesocoxae. Clypeus ( Figs 7, 8 View FIGURES 1–8 ) tricarinate; basal width about two thirds its length. Antennae with scape and pedicel terete, pedicel nearly 1.5 times as long as scape.

Thorax. Pronotum ( Figs 1, 3, 5 View FIGURES 1–8 ) subtrapezoidal; posterior margin bisinuate, medially concave; median carina present; lateral carinae distinct, diverging and reaching posterior margin. Mesonotum ( Figs 1, 3, 5 View FIGURES 1–8 ) with apex acute; median carina present; lateral carinae diverging and reaching hind margin.

Legs. Metatibiae with one lateral tooth near tibiofemoral articulation and a second tooth near mid-length. Calcar with fine teeth on hind margin.

Male abdomen. Apodemes of sternum I ( Fig. 9 View FIGURES 9–21 ) long and well separated. Pygofer ( Figs 10, 11 View FIGURES 9–21 ) in lateral view higher than long; ventral surface longer than dorsal; opening with no ventral processes; diaphragm not produced and with excavation, medially narrow. Suspensorium short ( Fig. 12 View FIGURES 9–21 ). Phallus ( Fig. 12 View FIGURES 9–21 ) simple, distinctly curved ventrad. Genital styli ( Figs 13, 14 View FIGURES 9–21 ) simple, from lateral view geniculate. Segment X ( Figs 12, 15 View FIGURES 9–21 ) wider than long (dorsal view), without processes.

Etymology. From “ Salinas” (Salt Marshes), based on the type locality of the type species, Salinas de Copiapó. Gender feminine.
