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 : 34-36

Icaia laoroya sp. nov.

( Figs. 12–23 )

Length of male 2.7–3.1 mm, length of female 3.2–3.8 mm. Color ivory to ochraceous with extensive brown to black markings. Crown heavily marked with black or dark brown, sometimes with a pair of small black spots posteriorly, but spots sometimes not apparent in strongly pigmented specimens, as broad black pigmentation covers them (as in holotype); posterior margin, median line, and anterior margin fuscous; apex with a pair of small black spots; crown slightly depressed posteriorly on each side and with a small depression anteriorly; rounded to face. Legs marked with brown. Front tibia formula 3+3. Hind femur macrosetal formula 2+2+1, with posterior­most seta of penultimate pair reduced in size. Brachypterous, wings exposing 4 to 5 pregenital abdominal segments; strongly reticulated.

Male. Pygofer spatulate, with numerous scattered short setae; lateral cleft not membranous. Subgenital plates with several scattered short setae. Tenth segment membranous except for a pair of ventrolateral sinuate bands. Connective very long; anterior arms long and gracile, appressed anteriorly; stem long and expanded posteriorly. Style preapical lobe bluntly pointed, with a patch of fine setae arising from dorsal side; apophysis falcate. Aedeagus with a pair of ventrolaterally directed processes arising laterally near apex; constricted laterally about 1/3 distance of shaft to apex, with several distinct setae on caudal surface at constriction; with a distinct medial ridge on apical 1/4 of caudal surface.

Female. Pygofer with a few short macrosetae near apex. Seventh sternite slightly convex medially and gradually tapering to sides; dorsal connective tissue partly sclerotized and forming a semicircular­shaped band anteriorly. First valvula dorsal sculpturing pattern maculose to granulose, submarginal. Base of first valvula with a dorsal hump. Second valvula dorsal teeth of the typical chiasmine shape, extending over one half of the apical dorsal margin. Gonoplac with numerous short setae near apex.

Nymph. Abdominal chaetotaxy Type IV of Dmitriev (2002). Color greyish to fuscous or ochraceous, with brown markings. Crown with depressions on either side of medial line posteriorly, with depressions next to eyes, and with depression at apex. Head produced, median length about 2x that of inner margin of eye. Face greyish or fuscous with anterior half of frontoclypeus and entire clypellus dark brown.

Material examined. Holotype male, PERU: Junín, 42 km NE / La Oroya, 4000m, 11°24’18”S / 75°50’31”W, 17 Oct 2002 / C. Dietrich & R.Rakitov / sweeping, 02­15­2. 9 male, 6 female, and 3 nymph paratypes, same locality; 4 male, 8 female, 4 nymph paratypes, same locality, collected by R.Rakitov, vacuum, 02­15­3; 1 male and 1 female paratype, PERU: Junín, 3 km W / Curipata, 3800m / 11°36’36”S 75°57’25”W / 17 Oct 2002, R.A. Raktiov / vacuum, 02­13­3; 1 female paratype, same locality, collected by R.A. Rakitov, sweeping, 02­13­4; 2 male and 2 female paratypes, PERU: Junín / 6 km S Junín, 4000m / 11°12’15”S 75°56’13”W / 28 Oct 2002, C.H. Dietrich / sweeping, 02­49­2. Holotype deposited at MUSM. 10 male, 12 female, and 7 nymph paratypes deposited at INHS, 2 male and 2 female paratypes at CNC, 2 male and 2 female paratypes at UCMC, and 2 male and 2 female paratypes at SEMC.

Etymology. The species name is a noun in apposition. It is named for the town closest to the type locality, the mining town of La Oroya, and is dedicated to its people in their struggle for a clean and healthy environment.

Diagnosis. This species is distinguished from other Icaia by the shape of its aedeagus and the presence of paired subapical processes ( Figs. 14, 15 ).
