Krishnankutty, Sindhu M. & Dietrich, Christopher H., 2011, Taxonomic revision and phylogeny of an endemic leafhopper genus Nesocerus (Hemiptera: Cicadellidae: Idiocerinae) from Madagascar, Zoological Journal of the Linnean Society 162 (3), pp. 499-543 : 520-525

NESOCERUS SCLEROPHYLLUS SP. NOV.

( FIGS 3K, L , 6Z, A 1 , 16C, D )

Diagnosis: Males of this species are similar to those of N. angulatus in habitus and male genitalia morphology, but may be distinguished by the uniform width of the preatrium in posterior view and the presence of long apical aedeagal processes reaching almost the midlength of the shaft.

Description: Length of male, 4 mm; female, 4.9 mm:

Coloration and structure: similar to that of N. angulatus .

Male genitalia: Pygofer, subgenital plate, style, connective as in N. angulatus . Aedeagus in lateral view with atrium narrow, socle well developed, preatrium in posterior view with apex as broad as base, shaft in lateral view broad, curved slightly anterad, slightly tapered towards apex; apex in posterior view acuminate, with pair of long, ventrally directed apical processes reaching almost middle of the shaft, then curved laterad. Gonopore subapical.

Female genitalia: Same as in N. trilineatus

Material examined: Holotype male, MADAGASCAR: Province Antananarivo, 46 km north-east of Ankazobe, Ambohitantel , 700 m, 18°11′52″S, 47°16′53″E, 15.x.–1.xi.2004, M. Irwin, F. Parker & R.
