MADAGASCARITIA SONG & LIANG GEN. NOV.

Type species

Madagascaritia angusta Song & Liang sp. nov., by present designation.

Diagnosis

This new genus can be separated from other Aluntiini genera by the following combination of characters: cephalic process with dorsal surface very narrow and compressed laterally before the eyes, so it becomes nearly triangular in cross section; frons with intermediate carinae strongly elevated, median carina incomplete or complete but obscure in middle; tegmina with costal cell distinctly narrow, coriaceous, opaque, and bright yellow, with suboblique veins (although observed with difficulty because of sclerotic surface), without dendroid secondary veins; basal three-quarters with dendroid nodose secondary veins densely interspersed among longitudinal veins; Sc+R, M, and CuA first branching nearly abreast.

Description

General colour ochraceous in dead specimens (probably viridescent or stramineous green in life).

Head ( Fig. 11A–C ) distinctly elongate, 1.5–1.8 times as long as pronotum and mesonotum combined. Cephalic process with dorsal surface very narrow and compressed laterally before the eyes in dorsal view ( Fig. 11A ), so it becomes nearly triangular in cross section. Vertex ( Fig. 11A ) with median carina absent, only median furrowed suture visible; lateral carinae strongly ridged, convergent anteriorly between eyes, slightly sinuate in front of eyes, and then narrowed and nearly subparallel towards apex, but apex acuate; posterior margin weakly ridged, arcuately concave. Frons ( Fig. 11C ) with lateral carinae narrow and elongate; intermediate carinae strongly elevated, converging posteriorly and extending before eyes; median carina incomplete, or complete but obscure in middle. Clypeus, rostrum, eyes, ocelli, and antennae similar to Aluntia .

Pronotum and mesonotum ( Fig. 11A ) similar to Aluntia . Tegmina ( Fig. 2F ) elongate and broad, translucent, and dull whitish, nearly 2.5 times as long as broad; costal cell very narrow, mostly coriaceous, opaque, and bright yellow in colour, with suboblique veins (although observed with difficulty because of sclerotic surface), without dendroid secondary veins; apex rounded; basal two-thirds with dendroid nodose
