El-Sonbati, Saad A., Wilson, Michael R. & Al Dhafer, Hathal M., 2015, A new species of the leafhopper genus Naevus Knight, 1970 (Hemiptera: Cicadellidae: Deltocephalinae: Opsiini), from Saudi Arabia, Zootaxa 4059 (2), pp. 393-400 : 397-399

Naevus hathali El-Sonbati & Wilson sp. n.

( Figs 3−15 )

Description. External morphology as given for genus. Aedeagus with apex of shafts expanded and rounded in lateral view with short anteriorly directed beaklike projection; elongate recurved processes situated preapically on inner margin of either shaft and extending to mid length of shaft, throughout length almost parallel to shaft; subapical process only on right side asymmetrically with apex very close to end of apical process; neither apical process nor single subapical process visible in lateral view; connection of aedeagus to connective free; connection of styli to genital plates style free; stylus with inner process elongate; subapical tooth of stylus poorly developed; pygofer about 1.5x as long as tergite VIII; pygofer with well differentiated macrochaetae; connection of genital valve to pygofer free; shape of posterior margin of genital valve produced medially; genital plates without macrosetae on or near lateral margin; subgenital plate with apical fingerlike process.

Note: all males examined have a lower inner spine on the right side only, making the aedeagus asymmetrical.

Female genitalia: Seventh sternite approximately 3 times as broad at base as long medially, with sinuous posterior margin, posterolateral angles conically rounded (fig. 15). Ovipositor depressed beyond pygofer apex. First valvula mediately convex. Second valvula gradually tapered apically with almost imperceptible serrations on dorsal surface of short. Dorsal sculpturing pattern maculose or with definitely delimited scales (fig. 6). Numerous macrosetae on pygofer.

Measurement. Length; male 3.8 − 4 mm, female 3.9 − 4.1 mm.

Differential diagnosis. The new species is closely related to Naevus dorsiplaga , but can be separated in the male aedeagus which has a preapical process and a single subapical process, neither of which is visible in lateral view, the subapical process reaching to less than one half of the length of the shaft.

Etymology. This species is named in honour of Dr Hathal M. Al Dhafer taxonomic entomologist, Department of Plant Protection, College of Food and Agriculture Sciences, King Saud University, Kingdom of Saudi Arabia.
