Gnezdilov, Vladimir M., 2020, Three new species of thegenus Tartessus Stål (Hemiptera: Cicadellidae: Tartessinae) from Vietnam, Zootaxa 4852 (3), pp. 350-360 : 355-356

Tartessus kabakovi sp. n.

( Figs 21 , 26–33 )

Description. In structure and coloration similar to T. iridescens sp. n. First metatarsomere with only 2 short macrosetae in the middle row ventrally.

Coloration ( Fig. 21 ). General coloration of the head and body with legs light brown yellow, except wide transverse black stripe below ocelli. Forewings light brown, with green tint; costal margin with black stripe in proximal part of the wing; R and M brown, other veins light brown yellowish. Claws dark brown to black dorsally.

Male genitalia ( Figs 26–33 ). Anal tube wide and long, narrowing apically (in dorsal view) ( Fig. 27 ), with one large apically tapered process bearing small spine near base on each side (in lateral view) ( Fig. 26 ). Pygofer lobes triangular with apices rounded, without processes ( Fig. 28 ). Genital valve concave medially ( Fig. 30 ). Subgenital plates wide and long, gradually narrowing apically, each with short row of nearly ten thick setae apically and with hair-shaped sparse microsetae on most of ventral surface and with a row of long hair-shaped setae on outer margins wrapped inward ( Fig. 29 ). Style with apical part narrowing to slender apex and with six subapical setae ( Fig. 31 ). Connective short and wide. Aedeagus with wide and strongly s-shaped shaft (in lateral view) ( Fig. 33 ), with pair of short apical processes extended anterolaterad and subapical gonopore. Lateral margins of aedeagal shaft dentate ( Fig. 32 ).

Total length. 11.0 mm.

Etymology. The species is named after collector, Oleg N. Kabakov (1928–2009)—well known Russian geologist, entomologist and collector.

Type material. Holotype: male, “D. R. Vietnam / Tam Dao / O. Kabakov VIII [1]963”. The label is in Russian, partly printed and partly hand written.

Distribution. Northern Vietnam: Vinh Phuc Province.

Differential diagnosis. The new species distinctly differs from other species of the genus for which the structure of male genitalia is known (e.g. Evans 1981; Linnavuori 1960; Metcalf 1946) by the wide, s-shaped aedeagal shaft.
