Genus Liara Redtenbacher, 1891

Liara Redtenbacher, 1891: 444 . Type species: Liara rufescens Redtenbacher

Diagnosis. Medium sized Conocephalinae with rather large and broad head. The pronotum is tunnel-shaped in cross-section, with the disc rounded into paranota, the apical area is subflat and shouldered and often slightly raised in male. The prosternum is unarmed, the mesosternal lobes are long-conical, the metasternal lobes short-conical or acute-angular, and the medial plate with a short spine or obtuse tubercle at both apical angles. Wing condition is often brachypterous, few species are fully winged. The femora, especially the mid femur, are slightly compressed. The male cerci are curved mediad and divided in apical area into a broad, often circa spoon-shaped, dorsal lobe and a narrow, band-shaped ventral lobe; sometimes with one or both lobes more strongly modified. The titillators of the male phallus are rather uniform between species; they are separate or rarely subfused near base, the apical parts subparallel except at very apex, with a lateral membranous sacculus or at least a lateral widening. The female ovipositor is compressed blade-shaped with the dorsal margin widened behind base, smooth margins, and the apex obliquely truncate. Coloration of the alive insect is often yellowish brown with black marks. The genus is very close to Unalianus Koçak & Kemal, 2009 (replacement name for Oxystethus Redtenbacher, 1891 due to homonymy) from which it only differs by the shape of the titillators.
