description: Genus Andes Stål, 1866
Andes Stål, 1866: 166.
Leirioessa Kirkaldy, 1907: 112 (synoymized in Muir 1925: 201).
Andes – Muir 1925: 201. — Zhou et al. 1985: 23. — Tsaur et al. 1991: 67.
Type species
Andes undulatus Stål, 1870 (subsequent designation in Muir 1925).
Diagnosis (modified from Tsaur et al. 1991)
Vertex narrowest and transverse at apex, widening to base, with U- or V-shaped basal emargination; lateral carinae strongly elevated; median carina absent. Forewing in resting position steeply tectiform; ScP +RA, RP and MP arising separately from a common point on basal cell or forming a minute common stem. Fore coxa with outer margin straight, subparallel with inner margin, not produced. Hind tibiae without or with several very small lateral spines. Chaetotaxy of hindtarsi 7–9/7–8.
Distribution
Palaearctic Region, Oriental Region, Australian Region and Afrotropical Region.
