A new species,
The genus
The aim of this paper is to define the taxonomic status of the species belonging to the “
The specimens were examined using the light microscope Nikon Ni-U. Drawings were made with a camera lucida. Measurements are given in mm (

---|---|---|
Dorsal chaetotaxy | Thorax and abdomen very densely covered by very thin, fine and pointed setae, 0.037–0.050 mm long | Thorax and abdomen covered by very short, inconspicuous setae, arranged in 3–4 rows on each segment with blunt, capitate, spatulate or club-shaped apices, 0.010–0.020 mm long |
Head setae | As long as setae on antennae, fine with pointed apices | Shorter than setae on antennae, slightly thick and forked |
Antennae | Antennal segments swollen | Antennal segments not swollen |
Siphunculi | Siphuncular sclerites very low, siphunculi almost poriform, with little-developed flange with 2–3 rows of polygonal reticulation | Siphuncular sclerites well-developed, with very well-developed flange with 8–10 rows of polygonal reticulation |
Abdominal cuticle | Smooth | Wrinkled or reticulated |
Hind tibiae chaetotaxy | Some setae on distal part of tibiae 3–4 times longer than other setae, 0.14–0.15 mm long | Some setae on distal part of tibiae 4–5 times longer than other setae, 0.17– 0.22 mm long |

The holotype and paratypes of the new species are deposited in the Natural History Museum London, UK, (BMNH). Paratypes will be also deposited in the aphids collection of the Department of Zoology, University of Silesia, Poland (UŚ).
Main differences in pigmentation and chaetotaxy of hind tibiae and size of siphuncular sclerites among apterous viviparous females of the “
The new species can be distinguished from
The name of the new species is derived from characteristically short and inconspicuous setae on the dorsal part of the thorax and the abdomen.
The species live on branches and shoots of
Turkey, Uşak-Eşme.
Holotype: one apterous viviparous female marked as 1. TURKEY, Uşak-Eşme, 850 m, 10.VI.1964, no 731/64, 45a1, M. Canakçioglu leg. BMNH.
Paratypes. Same locality as holotype: one apterous viviparous female marked as 2, no 731/64, 45a1; four apterous viviparous female marked as 1, 2, 3, 4, no 731/64, 45a2 BMHN; four apterous viviparous female marked as 1, 2, 3, 4, no 731/64, 45a3 UŚ.
Other material examined: 22 apterous viviparous females, same locality as holotype: no 731/64, 45a4–45a9 BMHN.
