A new leafhopper genus with two new species related to Masiripius Dlabola, 1981 (Hemiptera, Deltocephalinae, Cicadellidae, Opsiini)

. The genus Oshaibahus El-Sonbati & Wilson gen. nov. is described with the type species Platymetopius zizyphi Bergevin, 1922. Two new species, O. kadiae El-Sonbati & Wilson gen. et sp. nov. from Sudan and O. linnavuorii El-Sonbati & Wilson gen. et sp. nov. from Iraq are described, and a new combination, Oshaibahus zizyphi (Bergevin, 1922) gen. et comb. nov. is proposed. The genus Masiripius Dlabola, 1981 (type species: Mahalana lugubris Distant, 1918) is rede ﬁ ned. An illustrated key to genera of the subtribe Opsiina and a key to species of Oshaibahus gen. nov. are presented to facilitate identi ﬁ cation .


Material and methods
Specimens examined are deposited in King Saud University Museum of Arthropods, College of Food and Agriculture Sciences (KSMA), King Saud University, Riyadh, Saudi Arabia; in the National Museum of Wales, Cardiff, UK (NMWC) and in the American Museum of Natural History, New York, USA (AMNH).Genitalia preparations were made by soaking the excised apex of the abdomen in hot 10% KOH solution for 8-10 minutes.The apex of the abdomen was washed in distilled water and then transferred to glycerin for further dissection and examination.After examination, it was moved to fresh glycerin and stored in a micro vial pinned below the specimen.The distribution data were based on georeferencing material examined and plotted using Google Earth.The map was created using the program ArcGIS v.10.3.All specimens were examined with a Leica LABOPHOT-2 stereomicroscope, hand-drawings of the male genitalia were made with a NIKON microscope, with a drawing tube attachment.Images were taken using a Canon 70D DSLR attached to a Leica Z6 microscope.Individual source images were then stacked using Helicon Focus v.6.22 (Helicon Soft Ltd) extended depth of fi eld software, with calibrated scale bars added using Syncroscopy Automontage v.5.4.Resultant images were saved as TIFFs (Tagged Image File Format) with LZW lossless compression at 3648 × 2432 pixel dimension.Morphological terminology follows Dietrich (2005).Measurements are in millimetres (mm).
This work was part of a M.Sc.degree program by the fi rst author at King Saud University completed under the supervision of the second author at National Museum of Wales, Cardiff (NMWC).

Diagnosis
The combination of three characters must be examined to distinguish Masiripius from all other genera of Opsiini: (1) aedeagus without basal process with two shaft branches arising from base, (2) each shaft gradually narrowing at apex, and (3) vertex, pronotum, and scutellum with irregular red markings.

Description
BODY LENGTH.Male 3.8 mm, female 4.2 mm.
COLOURATION.Irregular red markings on vertex, pronotum and scutellum ground colour brownish yellow with numerous scattered brown spots and irregular reddish-brown spots.
HEAD.Head as wide as pronotum, crown slightly shorter next to eye than median length, vertex punctate, shagreen and slightly more produced in male, longer than next to eye in female, irregularly rugose, rounded to face.Frontoclypeus narrow, longer than wide, length more than 2 × of width; clypeal suture straight and obsolete medially, clypellus tapered, parallel-sided, greatly produced beyond gena, apical margin sinuate, wider or subequal to lorum width; gena slightly incised; ocelli situated on anterior margin of head and close to eye; mesal margin of eye entire; lateral frontal suture reaching ocellus and directed mesad of ocelli; antennae long; antennal ledge weakly developed; antennal base situated; near middle or posteroventral (lower) corner of eye.
THORAX.Pronotum with short lateral margin, irregular blotch-like striations and produced anterad of eyes, without carinae, about 1.5 × as long as scutellum; scutellum wider than long, with separate irregular blotch-like striations beyond scutellar suture.
WINGS.Forewings about 3 × as long as wide, appendix restricted to anal margin, A1-A2 veins coalescing over part of their length.
LEGS.Legs yellow with brown spots.Profemur row AM with AM1, one intercalary row with more than fi ve fi ne setae (or greatly reduced or absent), two dorsoapical setae, AV row with numerous stout setae, slightly short; protibia AD row with numerous macrosetae, PV row with 1-4 macrosetae; metatibia arched throughout its length, PD row with long and short macroseatae alternating or subequal in length, AD row with macrosetae and smaller intercalary setae, AV row with numerous macrosetae and extending nearly to base; metafemur setal formula 2+2+1; metatarsomere I length equal or longer to tarsomeres II and III combined; setal areolae on legs.MALE GENITALIA .Pygofer with well differentiated rows of macrosetae, without a process, long-curved ventral margin, long setulate apically; valve articulated with pygofer,with narrow point of articulation; subgenital plate with one row of macrosetae at apical margin; style bent, small, fi ngerlike, broadly bilobed median anterior lobe and preapical lobe well developed, tooth well-developed preapically; connective articulated with aedeagus, linear, the arms contiguous; aedeagus without basal process, aedeagal shafts arising from base.

Distribution
India (Metcalf 1967), Iran (Dlabola 1981), Oman and Qatar (present study).The separation and distinctiveness of Masiripius from Oshaibahus gen.nov. is based on the basal process, apical shaft branches of the aedeagus and apodemes.In Masiripius, the aedeagus lacks a basal process, the shafts are relatively straight, narrowing at the apex.Additionally, the abdomen has welldeveloped apodemes.In Oshaibahus gen.nov., the aedeagus bears a basal process branching from base curving preapically with a stout apex.The abdomen lacks basal apodemes.
Both Masiripius and Oshaibahus gen.nov.can be distinguished easily from Afrascius and Japananus by the absence of a marginal carina on the pronotum and the aedeagal shafts separated at the base, and from Pugla by the absence of a marginal carina on the pronotum, with compound eyes narrowly separated forming diamond-shaped crown.

Etymology
This genus is named in honour of Prof. Alaa Oshaibah, Systematic Entomologist, Department of Zoology, Faculty of Science, Al-Azhar University, Cairo, Egypt.The gender is considered masculine.FEMALE GENITALIA.Seventh sternite more than 2 × as broad at base as long medially, posterior margin lobe-like, with median V-shaped notch in middle, posterolateral angles conically rounded or acutely rounded.Ovipositor depressed beyond pygofer apex.First valvula medially convex.Second valvula gradually tapered apically with variable serrations on dorsal surface.Numerous macrosetae on pygofer.

Etymology
The patronym honours the co-author's youngest daughter, Kadi Al Dhafer.23-26).In addition to generic characters, the specifi c characters for this species are: clypellar suture convex at apex; lorum as wide as clypellus at base, not widely separated from genal margin; frontoclypeus texture rugose with "netlike" brown colour; crown 2 × as wide as eye.

Discussion
The genus Masiripius was described based on a misidentifi ed specimen from Iran (Dlabola 1981).Webb & Godoy (1993) examined the holotype of Mahalana lugubris and designated this taxon as a senior synonym of Zizyphoides punctatus and also of M. zizyphi, which had been misidentifi ed by Dlabola. Webb & Godoy (1993) also transferred Mahalana lugubris to Masiripius.Viraktamath & Anantha Murthy (1999) designated M. lugubris as type species of Masiripius.Platymetopius zizyphi is here designated as the type species of Oshaibahus gen.nov.
In this paper, we describe a new genus in the Opsiini-Oshaibahus El-Sonbati & Wilson gen.nov.-and two new species: O. kadiae El-Sonbati & Wilson gen.et sp.nov.from Sudan and O. linnavuorii El-Sonbati & Wilson gen.et sp.nov.from Iraq.The new genus is closely related to Masiripius Dlabola, 1981; male genitalia must be examined to distinguish between and separate the genera.The world distribution for both genera is shown in Fig. 1: Oshaibahus El-Sonbati & Wilson gen.nov. is known from Algeria, Libya, Iraq, Sudan and the Kingdom of Saudi Arabia (Muzahimiyah in Al Khararah and Rhodet Khorim, Figs 2-3); the known distribution of Masiripius includes India, Iran, and also Oman and Qatar of the Arabian Peninsula.
Masiripius, except O. kadiae gen.et sp.nov.that is dusky dorsally.Oshaibahus gen.nov.can be separated from Masiripius by the following characters: MALE GENITALIA.Aedeagus with basal process, shafts arising from base but with stout apex.
