Description. The genus Paranataretus gen. n. can be recognized by the following combination of features:

Body length: 5.2–5.6 male, 5.0– 6 female.

Coloration: Vertex with irregular brownish-yellow spots or shorter longitudinal stripes, expanded to lateral margin, and laterad of whitish median line. Pronotum brownish with dense irregular whitish spots. Mesonotum with whitish marks. Scutellum with whitish marks medially and at corners. Forewing with dense irregular whiteyellowish spots or pattern, with whitish costal margin, whitish costal margin with two brownish reflexed veins and dense brown irregular spot ( Figs 1, 2 ); with ( Fig. 1 ) or without ( Gnezdilov 2020, Fig. 1 ) regular white spots at both claval margins. Ground ventral color light yellow whitish but abdominal tergites dark brown, legs with small brown setal areolae, claws brown.

Head: Head narrower than pronotum. Crown, slightly concave, irregularly rugose, produced, triangular, margins rounded to face, equal or more than two times eye width. Anterior margin of head irregularly textured ( Fig. 1 ). Face elongated. Ocelli close to eyes, near lateral margins of crown, slightly visible from above, mesial margin of eye entire. Gena expanded beyond eyes and slightly visible in dorsal view, not incised. Antenna long, near middle of eye, without ledge. Frontoclypeus width equal or 1.5 times of gena width directly below eyes, without median longitudinal carina ( Fig. 4 ), longer than wide, slightly inflated, without long fine setae laterally on frontoclypeus. Lateral frontal suture extent reaching ocellus, length above antennal pit shorter than clypeo-genal suture, directed laterad of ocelli; ratio of frontoclypeal-loral suture to clypellar-loral suture less than 1/3. Lorum separated from genal margin, equal to clypellus at base. Clypellar suture complete, arcuate. Clypellus expanded apically ovoid, not inflated in lateral aspect, concave apically ( Fig. 3 ).

Thorax: Pronotum with lateral carina ( Figs 2, 4 ), anterior margin produced, posterior margin concave to straight, short lateral margin ( Fig. 1 ).

Wings: Forewing rounded at apex, more than three times as long as wide, with three anteapical cells, with reflexed costal veins, with crossvein m-cu2, A1 crossvein between A1 and claval suture present, appendix with wide, restricted to anal margin. Hind wing submarginal vein complete ( Figs 1, 2 ).

Legs: Profemur with well-developed AM1, AV1 long, similar to AM1 but short, intercalary row with nine fine setae, AV row with numerous stout setae, with two dorsoapical setae ( Fig. 14 ). Protibia dorsal margin rounded, AD row with one macrosetae, AV row with numerous macrosetae, PD row with four macrosetae. Mesofemur AV row with five macrosetae with fine setae in between, AD row with five setae widely spaced, PD and PV rows with four moderate setae. Metafemur setal formula 2+2+1, penultimate pair setae set close to each other. Metatibia arched throughout length, AD and AV rows with stout macrosetae, similar to each other, PD and PV rows with alternating long and short setae. Metatarsomere I length equal to tarsomeres II and III combined, with two rows of macrosetae, one apical macrosetae ventrally and pair of macrosetae dorsally, with 4–5 platellae ( Fig. 2 ).

Male genitalia: Anal tube equal to or shorter than pygofer in lateral view ( Fig. 13 ). Pygofer brownish, with dense tufts of moderate setae ( Gnezdilov 2020, Fig. 5 ), or several scattered macrosetae posteriorly ( Fig. 13 ), side lobes broad or narrow, with ( Gnezdilov 2020, Figs 5, 8 ) or without ( Fig. 13 ) sclerified processes, with ( Fig. 13 ) or without membranous area covered with short setae. Valve free, wide, folded at apex, triangular, with pointed ends, reaches apices of style ( Fig. 12 ). Subgenital plate triangular, elongate, with uniseriate row of macrosetae laterally, with ( Gnezdilov 2020, Fig. 6 ) or without ( Fig. 11 ) scattered macrosetae in the apical half, with ( Fig. 11 ) or without ( Gnezdilov 2020, Fig. 6 ) dense short fine setae dorsally, acutely rounded apical margin. Style apical process elongated, curved laterally, apices smooth rounded, with ( Fig. 9 ) or without ( Gnezdilov 2020, Fig. 6 ) preapical lobe. Connective short, robust, almost U-shaped with well-developed arms ( Fig. 10 ). Aedeagus long and narrow, tubular, curved, S-shaped ( Fig. 5 ), with a wide apex in dorsal view ( Fig. 6 ), with an apical gonopore.

Female genitalia: Pygofer with dense macrosetae at upper half, ovipositor slightly surpassing pygofer apex; seventh sternite simple ( Fig. 18 ) or sinuated ( Gnezdilov 2020, Figs 4 , 13 ); first valvula ( Fig. 17 ) convex, with reticulate dorsal sculpturing pattern at margin, without dorsal elongation of sculpturing, with base not extended anteriorly; second valvula ( Fig. 16 ) broad, gradually tapered, without tooth on shaft; third valvula ( Fig. 15 ) with few irregular setae ventroapically.

Distribution. Madagascar ( Gnezdilov 2020); Saudi Arabia (present study) ( Fig. 19 ).

Diagnosis. This genus is similar to many genera in external features or genital structures (S-shape aedeagus) but can be identified by a combination of these characters: aedeagal shaft unified, with one gonopore, slender; pronotum with lateral carina; vertex-face transition smoothly rounded; tegmina with three closed anteapical cells. (More details are given in the discussion.)

Etymology. The name Paranataretus is a combination of the Greek word “Para” and the present related genus “ Nataretus ”; gender masculine.
