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

Two new species of the genus Isochlora Staudinger, 1882 are described: I. hreblayi Volynkin, Tth, Titov & Saldaitis, sp. n. (western Mongolia) and I. kozlovi Volynkin, Titov, Matov & Saldaitis, sp. n. (Qinghai Province, China). The type species of the genus-group names Chamyla Staudinger, 1900 and Grumia Alphraky, 1892 (I. arctomys Alphraky, 1897 and I. flora (Alphraky, 1892), respectively) are examined, and their synonymy with Isochlora is revised. The synonymy of Chamyla idia Staudinger, 1900 with Isochlora arctomys Alphraky, 1897 is revised as junior synonymies. Lectotypes are designated for Isochlora arctomys Alphraky, 1897, Chamyla idia Staudinger, 1900 and Grumia flora Alphraky, 1892. Isochlora intricans (Alphraky, 1882) is reported from Kazakhstan for the first time. Adults as well as male and female genitalia are illustrated.
