Gnezdilov, Vladimir M., 2023, A new species of the genus Paranataretus El-Sonbati, 2023 (Hemiptera: Cicadellidae: Deltocephalinae) from the continental Africa, Zootaxa 5389 (1), pp. 135-139 : 136

Paranataretus albertinus sp. n.

( Figs 1–8 )

Description ( Fig. 1 ). Structure. Vertex as long medially as wide between the eyes, with acutely convex anterior margin. Frontoclypeus elongate, not carinate. Hind margin of female sternite VII convex, with a pointed median process ( Fig. 8 ).

Coloration. Vertex black, with light median line and seven light spots—three elongate ones at anterior margin, two elongate ones on the sides of median line, and two triangular ones at posterior margin. Face, antennae, rostrum, body below, and legs light yellow. Abdominal sternites dark brown in middle, except entirely light yellow female sternites VI and VII, with black margins of median process on hind margin. Pronotum with black anterior half, dark brown with dense light dots in posterior half. Mesonotum black, with three light spots on scutellum margin in male and five light spots (three on scutellum margin and two in the middle) in female. Forewing corium generally brown, with dark brown veins and ivory stripe below costal margin and dark brown to black apically and below this stripe. Clavus brown, with dark brown veins. Hind wings brown, with dark brown veins. Claws dark brown. Gonoplacs light yellow, with brown lateral sides. First valvifers dark brown.

Male genitalia ( Figs 2–7 ). Anal tube short. Pygofer lobes elongate, each with an area of dense long setae below anal tube ( Fig. 2 ). Pygofer lobes without processes, fused below anal tube with a small comb ( Fig. 3 ). Genital valve nearly triangular, wide ( Fig. 7 ). Subgenital plates wide and short, each with a row of 7–11 long setae crossing the plate in its middle. Aedeagus S-shaped, strongly curved basally, with long and narrow tubular shaft, with simple tubular apex; gonopore apical ( Figs 4, 5 ). Connective short, X-shaped ( Fig. 6 ). Style long and narrow, with microsetae; apex narrowly rounded with denticles ( Fig. 6 ).

Total length. Male—6.9 mm (from apex of vertex to apices of forewings). Female (without head)—6.5 mm.

Etymology. The species named after the Albertine Rift.

Type material. Holotype, male, “ Congo Belge: P.N.A. / 27-V–7-VI-1957 / C. Donis 3104-05” // “Secteur Sud / Rwankwi, environs / Rumangabo, 1.500 m ”.

Paratype: female (head missed), “ Congo Belge: P.N.A. / 27-V–7-VI-1957 / C. Donis 3104-05” // “Secteur Sud / Rwankwi, environs / Rumangabo, 1.500 m ” .

Comparison. The new species differs from closely related P. brevis ( Gnezdilov, 2020) by larger size, slender and more elongate aedeagus, with simple tubular apex, elongate pygofer lobes, and wider subgenital plates with macrosetae crossing its middle ( Figs 2, 4, 5, 7 ).
