Zahniser, James N. & Hicks, Andrew, 2007, Three new species of Icaia Linnavuori (Hemiptera: Cicadellidae: Deltocephalinae) from Peru and distinction of the genus from Athysanella Baker, Zootaxa 1390, pp. 27-39 : 37-38

Icaia sp.

( Figs. 30–36 )

Color fuscous to stramineous with faint light brown markings. Crown produced, median length about 2x that of inner margin of eye; depressed medially; texture with coarse longitudinal striations. Ocellus 3– 4 x own width from adjacent eye. Brachypterous; wings opaque, irregularly textured, and veins not apparent. Legs fuscous with brown markings; protibia formula 2+3 or 3+3; hind femur macrosetal formula 2+1+0; macrosetae on dorsal side of hind tibia black to dark brown.

Female. Pygofer without macrosetae. Seventh sternite with a distinct medial notch. First valvula dorsal sculpturing pattern maculose to granulose, submarginal. Base of first valvula with a dorsal hump; strongly bowed basally. Second valvula dorsal teeth of the typical chiasmine shape, extending only over one third of the apical dorsal margin.

Material examined. Female, PERU: Junín / 6 km SW La Oroya, 4000m / 11°36’20”S 76°2’34”W / 29 Oct 2002, C.H. Dietrich / vacuum, 02­51­1. Specimen deposited at INHS.

Notes. This appears to represent another new species, but is not given a name because males, which have the most distinctive species­level characters, have not been identified.
