Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Coloradoa ajaniae Kadyrbekov sp.n. from host plant Ajania fastigiata (C.Winkl.)Poljak. is described from Kazakhstan.New species is similar to C. mesasiatica Kadyrbekov, 2004 but differs from latter by ratio of setae on 8th tergite to the diameter of 3rd antennomere near base (1.0-1.3 vs 0.8-1.0),by ratio of terminal processes to width of the head between eyes (0.27-0.36 and 0.33-0.55,respectively), by number of setae on 8th abdominal tergite (6-8 vs 8-10), and by host plant genus (Ajania vs Artemisia).New synonymy are proposed: Coloradoa brevipilosa (Ivanovskaja, 1958) = Coloradoa huculaki Szelegiewicz, 1981, syn.n., Coloradoa viridis (Nevsky, 1929) = Coloradoa nodulosa Zhang et Zhong, 1980, syn.n.A key to species of genus Coloradoa Wilson, 1910 is compiled.Key words: aphids, Aphididae,
