Diagnosis
S. omani can be distinguished from other species of the genus by the color pattern and the shape of the aedeagus. At least one other undescribed species with a very similar color pattern is known from sub-Saharan Africa, but differs from S. omani in details of the color pattern, especially on the crown, mesonotum, and base of the forewing, and in the male genitalia.
Etymology
This species is named in memory of Prof. Paul Wilson Oman, whose seminal work on the New World leafhopper fauna made the present work possible.

Description
SIZE. Male 4.8-5.0 mm, female 5.3 mm.
COLOR. Strikingly colored with contrasting bright yellow or ivory with dark brown areas. Crown bright yellow/cream colored, with irregular brown markings near anterior corners of eyes. Face brown with slight yellow markings. Pronotum and mesonotum brown laterally; bright yellow/cream colored medially, expanded toward apex of mesoscutellum. Forewing brown on basal 1/3; brown patch acuminate apically toward base of middle anteapical cell; hyaline or whitish on apical 2/3 except reflexed costal veins and apical veins tinged with brown and brown spot in 3rd apical cell. Legs and sternites mostly yellow except mesosternum brown; legs with brown pigment at bases of large setae.
BODY. Head narrower than pronotum; produced somewhat anteriorly; median length about 1.5 x length next to eye. Crown depressed. Anterior margin of head mostly shagreen, glabrous at tip; angled to face. Ocelli fairly large; situated laterally on anterior margin close to eyes. Frontoclypeus very long, narrow; shagreen. Antennal pits large, encroaching onto frontoclypeus. Antennal sockets situated above middle of eye. Antennae long, 1.5 x width of head or longer. Eyes notched along median margin. Clypellus expanded apically. Lorum wider than clypellus at base. Forewing veins R1 and R2+3 reflexed, strongly pigmented; with an extra reflexed costal vein; outer anteapical cell acuminate basally and apically; inner anteapical cell open; inner apical cell short, broad, triangular; with crossvein between A1 and claval suture; A1 strongly curved distally, meeting commissural margin nearly at right angle. Profemur row AV setae absent or reduced; intercalary row with ~10 long fine setae; row AM with AM1 only, situated near ventral margin. Protibia dorsal setae 1+4. Mesofemur row AV with numerous short, stout setae. Mesotibia dorsal setae 4+4. Metafemur apical setae 2+2+1. Metatibia row PD setae very long; longest setae nearly equal to or longer than protibia. Metatarsomere I long; apex with 5 platellae; apical row inner seta platellate.
MALE. Pygofer somewhat long, narrow; dorsal incision not reaching midlength; with numerous macrosetae medially on posterior half; posterodorsal apex with vertical row of ~8 very long macrosetae; internally with sclerotized bars reaching from base of segment X to anteroventral corner of aedeagus. Valve distinctly pointed medially. Subgenital plates long, triangular; with ~3 macrosetae laterally; with several long thin lateral and apical setae. Connective anterior arms touching apically; stem short; dorsal margin of stem produced in lateral view; fused to pair of processes. Processes of connective fused to each other along basal 2/3; fused to connective; in lateral view extending posterodorsally and curved posteroventrally near apex; processes flared toward apex in ventral view. Style preapical lobe distinct, with several long setae; apophysis long, gracile, with minute texturing. Aedeagus subquadrate in shape; posterior and dorsal margins indented; with flange from dorsoapical corner extending anteroventrally, spade-shaped in posterior view; gonopore on posterior surface near dorsal margin; disassociated from connective and connective processes. Segment X long; lightly sclerotized dorsally at base.
FEMALE. Sternite VII median length longer than width; produced medially; notched apically; with lateral lobes. Sternite VIII very darkly sclerotized medially. Pygofer with numerous ventral macrosetae; apex of each pygofer side with two bunches of 7-8 very long macrosetae; dorsoapical rim with group of 6 long macrosetae. First valvifers closely associate or lightly fused anteriorly; with distinct sclerotized margins. First valvula convex; dorsal sculpturing pattern strigate to reticulate, reaching dorsal margin. Second valvula with small irregular dorsal teeth reaching nearly to midlength; shaft with blunt dorsal tooth.
Remarks
This species is placed in Scaphoideus based on the following characters: forewing outer anteapical cell small, acuminate apically; forewing vein A1 strongly curved apically, meeting commissural margin at nearly right angle; connective with long pair of processes (in this case, processes are fused to each other basally and fused to connective); aedeagus disassociated from connective and connective processes.
