Duan, Yani, Gao, Yao & Dietrich, Christopher H., 2020, Pascoia, a new Deltocephalini leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae) from Peru, Zootaxa 4801 (1), pp. 185-190 : 189

Pascoia rakitovi Duan sp. n.

( Figs 1–4 )

Length. 5.0 mm.

Coloration and morphology. Fore margin of vertex with four fuscous dots, with pair of orange patches more posterad. Pronotum with three pairs of orange longitudinal bands. Most of mesonotum and scutellum orange. Forewing base orange transitioning to pale brown distally, with veins contrastingly white ( Figs 1 A–C). Face mostly pale brown, with paired white arcs corresponding to muscle scars of frontoclypeus ( Figs 1F, 1G ).

Male genitalia. Pygofer lobe with caudal margin bluntly angulate ( Figs 2A, 2B , 3A, 3B ). Valve caudal margin obtuse angulate ( Figs 2D , 3D ). Subgenital plate with 5 macrosetae ( Figs 2E , 3C ). Style preapical lobe acutely angulate; apophysis strongly curved laterad and relatively thick ( Figs 2F , 3E ). Connective shorter than aedeagus. Aedeagus with acute ventral angle near point of fusion with connective in lateral view, shaft nearly straight, abruptly narrowed near two-thirds length in lateral view, slightly widened at base of process then acuminate distally, processes extended from dorsal margin basad and crossing shaft; in posteroventral view slightly gibbous near midlength, processes extended along lateral margins of shaft for most of length then slightly divergent, sides of distal cleft acuminate and slightly divergent ( Figs 2G, 2H , 3F, 3G ).

Material examined. Holotype: male, Peru: Pasco Department P.N. Yanachaga Chemillén San Alberto Valley , ca. Refugio EI Cedro btw 2220–2270 approx, 10°32’S, 75°21’W, R. A. Rakitov, 11–X–2002 ( MSML) . Paratypes: 1 male, 1 female, same data as holotype ( INHS) .

Etymology. This species is named for R.A. Rakitov who collected the type specimens.
